From the current situation, only our country has recovered the supply of products in a short time, accelerating the trend of domestic replacement of PCB industry.
Almost every kind of electronic equipment, from small electronic watches and calculators to large computers and communication electronic equipment, as long as there are electronic components such as integrated circuits, in order to make the electrical int
In order to meet different market needs, pcb board manufacturers can open these different forms of files. Then, what materials need to be prepared before pcb board proofing? Follow long Bo technology to understand!
Flexible circuit boards are mainly used in some sophisticated products, mobile phones, computers, digital cameras. Flexible circuit boards have great advantages over ordinary circuit boards, light weight, and can be bent.
There are many other factors that can affect proper coating of the PCB, including failure to clean the components before coating, failure to remove the original tri-guard paint from the surface, electrostatic discharge, and possibly even poor construction

Flexible circuit board is made of polyimide or polyester film as a substrate with high reliability, excellent flexibility of the printed circuit board.
Flexural FPC has three main functions: flexural and reliability, economy and cost.
One. Introduction to FPCFPC: English full spell Flexible Printed Circuit, referred to as soft board.It is made of conductor circuit graphics by using optical imaging graphics transfer and etching process on a curving substrate surface. The surface and in
Circuit board negative circuit or copper surface is transparent, positive circuit or copper surface is black
With the continuous improvement of automobile safety, comfort and intelligence, PCB (printed circuit board) products are also facing the development of intelligent and green needs.
Signal integrity circuit board design criteria include SI problems, pre-design preparation, cascade, crosstalk and impedance control, high-speed nodes, technology selection, pre-wiring stage, post-wiring SI simulation, post-manufacturing stage, model sele
