Standard PCB service refers to full feature printed circuit board manufacturing service. With years' experience in pcb fabrication company, we have handled hundreds of thousands of PCB projects, and covered almost all kinds of substrate materials including FR4, Aluminum, Rogers, etc. This page only touches standard FR4 based PCB. For PCBs with special technical substrate, please refer to corresponding webpages for information.
Unlike Prototype PCB service, our Standard PCB service has tighter production tolerances. The following two articles will give you enough information about those two services on their introductions and differences:
PCB Prototype Service vs. PCB Standard Production
Pcbmain offers both prototype service and standard PCB production. While you will usually eventually use both services, there is an appropriate time for each. The difference is simple. With the prototype service, we take your design and quickly build a small batch of boards using basic materials, which we then ship to you in just a few days. The idea is just to give you a sense of whether your design works or not and worth it to do a full production run. You can test the boards to locate any design flaws before you make a big investment in PCB fabrication based on that design.
In standard PCB production, we are actually making the boards you will use in your applications. This will take a bit longer since we may be using different materials and more complex fabrication processes (. multi-layer designs), but it will usually still be as fast or faster than other PCB fabrication services. You will normally make a larger run of these, since you will actually be using these boards for your market applications.
If you are working from an existing design you have used before, you may want to jump directly to the standard PCB production service. Since design flaws are much less likely, it could save you some time to get the standard boards you need right away. If you are testing a new design, we highly recommend you engage our PCB prototype service. You will lose little time and be able to verify that your design works before standard production, which could save you considerable time and money if you do uncover design flaws.
Get Your Next PCB Design off the Ground with PCB Prototype Service
When you are just starting the development of a new product our rapid PCB prototyping service can help you get your new design from concept to production in record time. When developing a new product, quickly iterating through new versions of your design is of the utmost importance. Rapidly testing and correcting designs is what will allow you to hone in on a finished product as quickly as possible. Additionally, it is also well known that making large engineering changes to a design is best done in the early phases of product development. Quick-turn PCB fabrications service can allow you to locate just such design change requirements early in the development cycle. Spot design errors in low quantity prototype production runs of your PCB board before ramping up production volume. Hence, it allows you to refine your next design quickly at an affordable cost.
As the saying goes, "time is money" and waiting on long lead time PCBs can doom a project to failure. That is why we offer quick-turn PCB prototype service, which builds your proto boards in as few as 2 working days. Additionally, this service is well suited to low volume production runs with a minimum order quantity of only five boards.
Although our prototype PCBs do not have as high of production tolerances as standard circuit boards, they allow you to get a very good idea of how well your final production version work. Having an accurate view of how your final design will turn out is of great importance to ensuring that your design is successful. Our prototyping service provides you with a nearly identical product to that of a high volume standard production run, albeit at slightly lower manufacturing tolerances. Despite the lower production tolerances, we support track widths down to 4mils and track spacing down to 4mils, 5mils minimum annular rings and minimum drill sizes down to (8mils). Additionally, we can manufacture PCB up to 16 layers in layer count and 500x500 mm in size, covering most PCB applications. Reviewing these capabilities, it is apparent that our prototyping service will allow you to test and verify demanding tight tolerance designs at a lower cost, with shorter turnaround times than what you would encounter with standard PCB services.
When developing surface mount based solutions, it's also of great utility to order solder stencils for prototype assembly purposes. You need to test your circuit design and make sure it is good for huge production.
PCB Prototype Advantages:
Opportunity to do a small test run of your PCB design
Fast turnaround on your order
Identify any design flaws fast
You can change the design without having wasted an entire standard production run
PCB Prototype Disadvantages:
The boards’ tolerances are not as high as standard circuit boards
You will need to wait until you receive and test the prototype boards before formally ordering your standard production run Limited board materials
Limited number of layers for your boards

Aluminum PCB Advanced Circuits Specification
Aluminum Printed Circuit Boards Contain a Thin Layer of Thermally Conductive Dielectric Material that Transfers Heat.
There are many names for these products; Aluminum clad, aluminum base, Metal clad printed Circuit Board (MCPCB), Insulated Metal Substrate(IMS or IMPCB), Thermally conductive PCBs, etc… but they all mean the same thing and perform the same way.
How Are Aluminum PCBs Made?
A thin layer of thermally conductive but electrically insulating dielectric is laminated between a metal base and a copper foil. The copper foil is etched into the desired circuit pattern and the metal base draws heat away from this circuit through the thin dielectric.
Operating theory:
The power device surface mounting on circuit layer, it is ideally suited for the mounting of high power light emitting diodes (LEDs) easily dissipating the heat generated by power devices.
Aluminum based PCB used:
Benefits of Aluminum PCBs
Heat dissipation is dramatically superior to standard FR-4 constructions.
The dielectrics used are typically 5 to 10 times as thermally conductive as conventional epoxy-glass and a tenth of the thickness
Thermal transfer exponentially more efficient than a conventional rigid PCB.
Lower copper weights than suggested by the IPC heat-rise charts can be used.
MCPCB & Metal Core PCB & LED PCB
MCPCB, Aluminium PCB, or call LED PCB are the circuit boards which use a base metal material as the heat spreader portion of the Aluminum clad Circuit Board, Aluminum PCB has good thermal conductivity, electrical insulation and mechanical processing properties, it's the most excellent and cheap cooling solutions.
MCPCB/Metal core PCB can be advantageous to use for their ability to integrate a dielectric polymer layer with a high thermal conductivity for a lower thermal resistance. Metal core PCB transfer heat 8 to 9 times faster than Rigid FR4 PCB. MCPCB laminates dissipate heat, keeping heat generating components cooler which results in increased performance and life. Metal core PCB are most widely found in LED technologies, using a metal core PCB in these LED products and applications help to greatly reduce the heat emitted.
Pcbmain: An Experienced MCPCB Manufacturer
Pcbmain has been working with Metal PCB/LED PCB for several years. We have gained extensive knowledge and experience in manufacturing Aluminum PCB from single-sided to double-sided which mainly used in LED lighting industry.
Rigid-Flex circuit boards are composed of a combination of rigid and flexible circuit boards that are permanently connected to one another.
The proper application of Rigid-Flex circuit boards offers optimum solutions for difficult, limited space conditions. This technology offers the possibility of a secure connection of device components with the assurance of polarity and contact stability, as well as a reduction in plug and connector components.
Additional advantages of pcb bare board are dynamic and mechanical stability, the resulting 3-dimensional freedom of design, simplified installation, space savings, and maintenance of uniform electrical characteristics.
Use of Rigid-Flex circuit boards can reduce the total cost of the final product.
Rigid-Flex circuit boards give you unlimited freedom of packaging geometry while retaining the precision density and repeatability of printed circuits.
As a high reliability replacement for wire and wire harness assemblies, flex circuits provide a significant cost savings with no reduction in performance.
There are a variety of terminations for china pcb manufacturer and we can provide all of these as standard manufacturing process.
Rigid flex PCB circuit are a hybrid construction flex circuit consisting of rigid and flexible substrates which are laminated together into a single structure. Each layer of rigid-flex circuit are electrically interconnected by plated through holes (PTH), which is different from a flexible circuit with FR4/PI stiffener on top or bottom of flex circuit only by the means of preventive or thermal sensitive adhesive only, no PTH.
Printed Circuit Board Manufacturer
Rigid-flex board enjoy the advantage of both rigid FR4 PCB and flexible circuits. In rigid area, components will be soldered on, and whole board can be bendable at the flexible circuit area, so that to save space of assembly, make whole product into a small size but with tight trace designing.
Also people don’t need to solder the FPC on China PCB, or connect FPC on PCB via connector, furthermore, that plated through hole interconnection is more stable, firm than soldering or connector. So more and more rigid flex board circuit has been widely used in both military and civil area.
Double layers PCB is a pat
What is Flexible PCB?
Flexible printed circuit boards, also called Flexible PCBs or Flex PCBs, derive their name for their ability to enable the circuitry to be designed to fit the electronic device or product, as opposed to building the device to conform to the circuit board. Immersion Tin PCB are characterized by a distinctly patterned printed circuitry and component arrangement highlighted by a malleable base material.
What are Advantages of Flexible Printed Circuit Boards?
Flexible printed circuit boards offer a number of potential benefits including:
Saving Space. Flex PCB design requires only about 10 percent of the space and weight of an ordinary circuit board assembly, offering greater installation and packaging freedom. The inherent flexibility also permits tighter bend capabilities.
Maximum Reliability. A flexible printed circuit board requires fewer interconnects, which in turn requires fewer contact crimps, connectors and solder joints. Simply put, a flexible PCB board does not contain as many potential sources for failure, which enhances their reliability.
Enhanced Capabilities. The flexible printed circuits boards are compatible with virtually any type of connector or component and works well with options such as ZIP connectors. They also perform extremely well in extreme temperatures and offer superior resistance to radiation and chemicals.
Cost Savings. Cost-saving advantages of Flexible PCBs include reduced material and packaging demands, lower parts replacement costs and assembly errors that could result in the need for repairs.
Thsse benefits make flex PCBs ideally fit for a wide range of applications in industries such as Military, Transportation, Medical, Consumer Electronics, Automotive, Aerospace, Communications and Industrial.
Apart from all types of Printed Circuit Boards (PCBs) such as Prototype PCB, Standard PCB, Aluminum PCB, HDI PCB, Flex PCB, Flex-Rigid PCB, High-Frequency PCB, Thick copper PCB, High-Tg PCB and Halogen-Free PCB, Pcbmain also manufactures solder paste stencils to meet Surface Mount Technology (SMT) requirements.
Stencils, also called SMT stencils, play a key role in transferring accurate amount of solder paste to correct positions on bare circuit boards ready for assembly. In other words, stencils can fast and efficiently ensure the most accurate solder paste amount and optimal electrical connection. With solder stencils, it is possible to use metal squeegee blades to apply solder paste easily over the openings on PCBs and make stencil to be well aligned with the surface of the advanced circuit board.
According to SMT stencil manufacturing technologies, we provide two types of stencils: laser-cut stencils and chemical-etch stencils.
Laser-cut stencils
The openings are lasered on 100% stainless steel. Generally speaking, this kind of stencil can be produced with high quality and a high degree of precision within a short time.
Chemical-etch stencil
The openings are etched into the metal using acid. Usually this kind of stencil offers better protection on material temper and hardness.
High Frequency PCB
What is High Frequency (HF) PCB?
Electronic devices with high frequency is the developing tendency nowadays, especially in wireless network. Satellite communication growing rapidly, information products move towards high speed and high frequency. Thus developing new products always need to use high frequency substrate, satellite system, mobile telephone receiving base station and so on, these communication products must use high frequency PCB.
The features of Thick Copper PCB.
DK should be small and stable enough, usually the smaller the better, high DK may lead to signal transmission delay.
DF should be small, which mainly affect quality of signal transmission, the smaller DF could make smaller signal wastage accordingly.
The thermal expansivity should be the same with copper foil as much as possible, because the difference will lead to copper foil separated in the changes of cold and heat.
Water absorptivity must be low, high water absorptivity will affect DK and DF when in the wet environment.
Heat resisting property, chemistry resisting, impact endurance, peel off resisting must be good.
Materials used for HF circuit board.
High-frequency board for wireless applications and data rates in the upper GHz range have special demands on the material used:
Adapted permittivity.
Low attenuation for efficient signal transmission.
Homogeneous construction with low tolerances in insulation thickness and dielectric constant.
Generally speaking, high frequency can be defined as frequency above 1GHz. Currently, PTFE material is widely used in high frequency PCB China manufacturing, it's also called Teflon, which frequency is normally above 5GHz. In addition, FR4 or PPO substrate can be used to the product frequency among 1GHz~10GHz. These three high frequency substrate have below differences:
With regard to laminate cost of FR4, PPO and Teflon, FR4 is the cheapest one, while Teflon is the most expensive one. In terms of DK, DF, water absorption and frequency feature, Teflon is the best. When product application require frequency above 10GHz, only can we choose Teflon PCB substrate to manufacture. Obviously, the performance of Teflon is far better than other substrate, However, Teflon substrate has the disadvantage of high cost and large heat resisting property. In order to improve PTFE stiffness and heat resisting property function, a large number of SiO2 or fiber glass as the filling material. On the other hand, due to molecule inertia of PTFE material, which it is not easy to combine with copper foil, thus, it needs to do special surface treatment on the combination side. With regard to combination surface treatment, normally use chemical etching on PTFE surface or plasma etching to plus surface roughness or add one adhesive film between PTFE and copper foil, but these may have influence on dielectric performance.

High-TG PCB High Temperature PCB fr4 Material
The Glass Transition Temperature (Tg) is one of the most important properties of any epoxy and is the temperature region where the polymer transitions from a hard, glassy material to a soft, rubbery material.
Circuit board material must flame-resistant, it can’t be burned at a certain temperature and only be soften. The temperature point is called the glass transition temperature (Tg).
The higher Tg point means higher temperature requirement during lamination. And the Aluminum clad Circuit Boards will be hard and crisp, which will affect hole and the electrical properties.
Ordinary PCB materials at high temperatures, not only will be soften, deformation, melting and other phenomena, but also the mechanical and electrical properties decline sharply.
General fr4 Tg is 130-140 centigrade, moderate Tg is greater than 150-160 centigrade, High-Tg is greater than 170 degrees.
The higher of Tg, the better performance of PCB heat resistance, moisture resistance, chemical resistance, stability and other characteristics.
FR4 is a code name for grade of Epoxy Glass material.
Tg means Glass Transition Temperature.
When the working temperature reaches to the melting point, that means the temperature exceeds the Tg value, the status of pcb material will be changed from glassy to liquid, which will affect the function of pcb. And this value is related to the stability of the pcb dimension.
As usual, made with Tg ≥ 170℃ pcb material, which is called high Tg printed circuit board. With the rapid development of the electronics industry, high Tg material is widely used in computer, communication equipment, precise apparatus and instrument and etc.
Thick-Copper PCB
With the highly development of telecommunications and electronics industry, thick copper board is widely required by PCB customer. Thick copper PCB is mainly used for central power system and power electronic devices, which is because it enables the board to conduct higher current and decrease the product size.
China thick copper board mean the finished copper thickness of the board is more than 4OZ(140um), this is the most important factor for us to compare the thick copper PCB from those standard PCB with 1OZ or 2OZ copper.

What is HDI PCB
High density interconnect (HDI) PCB, represent one of the fastest growing technologies in PCBs. Because of its higher circuitry density than traditional circuit boards, the HDI PCB design is able to incorporate smaller vias and capture pads, and higher connection pad densities. HDI Boards contain blind and buried vias and often contain micro vias of or less in diameter.
By using HDI technology, designers now have the ability to place more components on both sides of the raw PCB if desired. Now as the development of via in pad and blind via technology, it allow designers to place smaller components closer together. This means faster transmission of signals and a significant reduction in signal loss and crossing delays.
HDI PCB is regularly found in mobile phones, touch-screen devices, laptop computers, digital cameras, 4G network communications, also prominently featured in medical devices.
Advantages of HDI PCB
The most common reason for using HDI technology is a significant increase in packaging density. The space that obtained by finer track structures is available for components. In addition, overall space requirements are reduced will result in smaller board sizes and fewer layers.
