PCB: Printed Circuit Board.
Main function: supporting and interconnection for circuit component.
In 1936,the concept about PCB was put forward by English Doctor Eisler and made the first piece of PCB.
In 1941,the PCB was applied to military equipment by America.
In 1953,appeared for double-side PCB.
In 1960,appeared for multilayer PCB.
In 1990,appeared for BUM(build up multilayer) PCB.
Basic Type: rigid PCB,Flexible PCB,Rigid-Flex PCB.
Layer: single-side PCB,double-side PCB,multilayer PCB.
Technology:HASL_LF,Gold finger,carbon oil,Au plating,OSP,Immersion gold,
immersion tin,immersion silver.
The example-production process for double-side PCB with HASL_LF:
Board cutting- drilling- PTH- Panel Au Plating- outer layer- pattern plating- outer etching- soldermask- silkscreen- HASL- Etest-FQC-FQA-package
1. IPC-A-600 (standard can be accepted for PCB)
2. IPC-6012(standard for rigid PCB)
3. IPC-6013(stand for flexible PCB)
4. IPC-TM-650(test method for PCB)
Final standard according to contract between customer and supplier.
PCB application field and acceptance check class:
A-class 1: for general electronics. Such as TV,toys,USB etc
B-class 2: for electronics of professional use only. Such as computer,instrument etc.
C-class3: for high reliability electronics. Such as military,aviation etc.
Printed circuit boards are widely used in many fields such as consumer electronics, communications equipment, automotive electronics, industrial equipment, medical electronics, smart security, clean energy, aerospace and military products, and are indispensable electronic elements in modern electronic information products. The level of development of the device and printed circuit board industry can to a certain extent reflect the development speed and technical level of a country or region's electronic industry.
In recent years, with the development of industries such as the downstream electronic information industry and the automotive industry, the demand for various electronic products has increased significantly, further widening the space for the development of the printed circuit board manufacturing industry.
