Reasons for blistering of multilayer circuit board
(1) Improper suppression leads to the accumulation of air, moisture and pollutants;
(2) In the process of pressing, due to insufficient heat, too short cycle, poor quality of semi cured sheet and inc
At present, the coating method of resist is divided into the following three methods according to the precision and output of circuit graphics: screen missing printing method, dry film / photosensitive method and liquid resist photosensitive method.
FPC soft board is an important electronic component. It is also the carrier of electronic components and the electrical connection of electronic components. Through the analysis of the development of FPC soft board in the main regions, the market dev
According to the base material, PCB can be divided into flexible circuit board, rigid circuit board and rigid flexible combination plate, which are used in different equipment according to different purposes.
