PCB Board Manufacturing
PCB board is one of the essential components of electronics product manufacture. Every electronic product needs PCB board manufacturer, from small watches and calculators to computers, communication electronic equipment, and even military weapon systems, PCB board manufacturing and PCB assembly are indispensable parts.
Analyze several development stages of PCB board manufacturing
Early Stages of PCB board manufacture
In 1948, the PCB board began to be used commercially. PCB manufacturer fabricate PCB with paper phenolic aldehyde copper foil substrates in the early days. The PCB wiring is mainly screen printing, so it calls a printed circuit board.
The mature stage of PCB Board
In the 1990s, electronic equipment continued to shrink, PCB circuit board manufacturer made PCB for the mechanical industry with a huge demand. At this time, PCB manufacturer has changed from circuit printing to dry film manufacturing. Transfer the original circuit diagram to the circuit board that needs to be manufactured through the principle of photosensitive imaging.
High-speed development Stage of PCB Board
In the 2000s, PCBs became more complex with more functions while the size became smaller. Especially multi-layer and flexible circuit PCB designs make these electronic devices more operable and functional, with small size and low cost PCB.
PCB Layers
Single layer PCB are used in simple electronic products, such as radios, simple speakers, and other OEM PCB products.
2 Layer PCB board is widely used in each electronic products from consumer electronics to industrial products as a cost-effective advantage in China PCB manufacturer.
A 4 layers PCB contains four conductive copper layers. The top and bottom layers are the signal layer, and the middle two layers are the power layer and ground layer. The power layer and the ground layer can be isolated in the middle to reduce interference.
MultiLayer PCB emerged with the development of science and technology, electronic products are required to be portable and smaller.
Main PCB Types
Most rigid PCBs are fabricated by FR4-based epoxy resin materials in China PCB manufacturer. Rigid PCB board is flat with the advantages heat-resistant, moisture-proof, mildew-resistant, acid-alkali-resistant, impact-resistant. Also it’s good mechanical properties, dielectric properties and processing properties in PCB manufacturer. It’s excellent electrical performance in wet and dry conditions. Especially good flame retardancy, little influence from the environment, stable dimensions.
The flexible circuit board is a highly reliable and excellent flexible printed circuit board made of polyimide materials by PCB manufacturer. It’s high wiring density, lightweight, thin thickness. And advantages of bending, folding, winding, and good heat dissipation performance. it can realize lightweight, miniaturization, and thin, so as to achieve the integration of component devices and wire connections. This design is easy PCB assembly manufacture for parts in small and fragile devices. Flexible PCB board is best suited for temperature-sensitive working conditions or industries-related equipment in OEM PCB factory.
Rigid-flex PCB board is a combined flexible circuit board and rigid circuit board manufacturing.
Advantages: The rigid-flex board has both the characteristics of Flex PCB board and Rigid PCB board. Therefore, it can be used in some products with special requirements. It has both a certain flexible area and a certain rigid area, which is helpful for saving the internal space of the product. , It is of great help to reduce the dimension of finished products and improve product performance.
Disadvantages: There are many production processes of rigid-flex PCB board in China PCB manufacturer. The PCB board technology is difficult, the yield rate is low, and more materials and labor are invested. Therefore, its price is relatively expensive and the production cycle is relatively long.
MCPCB is a metal-based copper-clad laminate with metal aluminum, copper, and iron as the substrate. It has good heat dissipation and is often used in high-power products. Such as LED photos, new energy vehicles, etc.
Rogers Series PCB board is a ceramic-filled PTFE composite material used in commercial microwave and radio frequency applications. It has excellent stability and a dielectric constant of 3 to 40 GHz at room temperature. The material has a dissipation factor (Df) of 0.0013 to 10 GHz, making it ideal for bandpass filters, microstrip antennas, and voltage-controlled oscillators.
PCB Assembly
King Sun PCB provides one-stop service for PCB manufacturing and PCB assembly.
PCB Components Purchase
We have a complete material procurement management and control process, and can quickly provide component quotations to customers.
Years of core supplier database accumulation, let our components quality assurance, price advantage. Of course, we also accept customers to provide BOM materials to our PCB assembly factory.

PCB Application
Consumer Electronics Products
Consumer electronics include: audio, video and DVD players, smartphones, televisions, smart watches, calculators, TV remotes, mp3 music players, toys, digital cameras, computers and laptops, mobile phones and GPS to home and kitchen appliances. Such devices often use standard PCB board that is fairly standard and similar to each other.
Medical Equipment
High-density PCB circuit board is always used in medical devices. They support new prototype testing and advanced medical technologies using denser PCB design. This also reduces the complexity of small, lightweight medical devices in PCB manufacturing.
Industry
PCB circuit boards are commonly used in industrial machinery and industrial control. For example, industrial machines such as motor controllers, industrial computers, industrial load testers, frequency converters, and measuring instruments,high-current battery charging all need PCB manufacturing.
Automotive and Aerospace
PCB circuit board is used in GPS navigation, car audio, car dashboard, car sensors, and other equipment in automotive electronics. In the aerospace industry, PCB circuit board is used in aircraft, aviation remote sensing systems, aviation radar and other equipment manufacture.
PCB Design
PCB design is based on the PCB schematic diagram to realize the functions required by PCB board design enginner. The design of the PCB board refer to below aspects:
Analyze how to design the schematic diagram, it will affect PCB board layout
In order to reduce PCB prototype manufacture errors and improve PCB design efficiency, we will use circuit simulation.
Design schematic components and build your own PCB component library
The PCB schematic diagram is an important part of the circuit board design. It contained various symbols, graphics, text and comment characters representing the actual electronic components. we can see each electronic component specific parameters from the circuit schematic diagram. Such as Model, nominal value and the connection relationship between each components. After completed schematic diagram, you need to use the ERC tool to check for errors until there are no principled errors.
It is necessary to design and build a new PCB component package library by yourself
First draw the outline PCB board follow PCB process requirements,then layout and route the PCB board. Routing rules include trace spacing, various line widths, size of vias, topology of wiring, etc., which need to be set according to the actual situation of the design.
