PCB Board Manufacturing

PCB board is one of the essential components of electronics product manufacture. Every electronic product needs a PCB board manufacturer. From small watches and calculators to computers, communication electronic equipment, and even military weapon systems, PCB board design manufacturing and PCB board assembly are indispensable parts. We analyzed 3 development stages of PCB board manufacturing.

1948—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.

1990s—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.

2000s—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.

 Our Clients

PCB Layers We provide

Single Layer PCB

Single layer PCB are used in simple electronic products, such as radios, simple speakers, and other OEM PCB products.

2 Layers PCB

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.

4 Layers PCB

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

MultiLayer PCB emerged with the development of science and technology, electronic products are required to be portable and smaller.

What is a Rigid PCB-rigid pcb material-single sided pcb manufacturer

PCB Assembly

PCB Components Purchase

We have a complete material procurement management and control process, and can quickly provide component quotations to customers. We also accept customers to provide BOM materials to our PCB assembly factory.

SMT Assembly Processing

Our PCB assembly manufacturer has first-class equipment, perfect quality control system, and rich practical experience, which makes our PCB assembly high efficiency, high quality, and price advantage.

Through Hole Assembly

After the PCB assembly is finished SMT, it enters the through hole assembly. Through hole asssembly generally adopts the wave soldering process, and the wave soldering machine is used for welding processing and firm components.

PCB Assembly Testing

We will do PCB functional test for PCB assembly according to the customer’s requirement.
