The first printed circuit boards were much simpler than the designs we see today. Containing far fewer solder connections and components, th
Three reasons for manufacturer is difficult to tin the High frequency PCB
FPC supplier tells you the advantages of AOI：
Restructuring a product to use flexible circuits instead of rigid boards presents immediate weight benefits. Users generally experience weight decreases of up to 75% when compared to conventional designs.
Almost everything on the Earth displays resistance and other parasitic properties.
As a rule of thumb, unless a customer requests functional testing, as a Flexible PCB manufacturer you should opt to use either in-circuit testing or flying probe testing to determine that your product is functional.
PCB factory china tells you the Influence and control of solder mask
Automated optical inspection uses cameras to take photos of a printed circuit board and compares them against detailed schematics to ensure that there are no mistakes on the board. The board is lit from various angles and several pictures are taken and assembled together to build a complete profile of the board.
PCB fabrication and PCB assembly are two distinct parts of the PCB manufacturing process.
Once all of the bugs have been worked out and any possible manufacturing variables have been amended, full production can begin.
