What is the future development trend of PCB circuit board technology?

Circuit board manufacturing belongs to the modern electronic industry. Circuit board is also called PCB board, aluminum substrate, high-frequency board, PCB circuit board, PCB, circuit board, printed circuit board, flexible board, etc. Nowadays, electronic circuit boards are widely used in various fields. Almost all electronic devices contain corresponding printed circuit boards. It is an important part of electronic equipment and the support of electronic components, which is equivalent to the lifeblood of electronic products.

Traditional circuit board manufacturing process:

Single board: cutting鈫抯creen printing鈫抍orrosion鈫抪rinting removal鈫抙ole processing鈫抪rinting mark鈫抐lux coating鈫抐inished product.

Double-sided board: cutting鈫抎rilling/laser鈫抌lack shadow鈫抍opper plating鈫抣aminate鈫抏xposure鈫扗ES鈫扖VL鈫抪ressing鈫抯older mask printing鈫抯urface treatment鈫抰ext printing鈫抏mpty board electrical testing鈫抪ackaging and shipment.

Multilayer board: Lamination 鈫?Drilling 鈫?Plasma 鈫?Shadow 鈫?Lamination Exposure 鈫?Copper Plated Hole 鈫?De-lamination 鈫?Secondary Lamination Exposure 鈫?Circuit 鈫?Cover Film 鈫?Solder Mask Ink 鈫?Gold Plating 鈫?Text Ink 鈫?Sticking Strong Sheet 鈫?Punching 鈫?Electrical Testing 鈫?Inspection 鈫?Packaging and Shipping.

In the future, the development trend of circuit board processing and manufacturing technology is to develop towards high density, high precision, fine pore diameter, fine wire, small pitch, high reliability, multi-layer, high-speed transmission, lightweight and thin.
