As the PCB industry of electronic products in mainland China, it has entered a stage of continuous and stable growth. As the global PCB industry manufacturing l...
There are also many varieties of silicone resin coating materials for pcb printed circuit boards, such as heat curing solution, 100% moisture curing solution, 1...
The reasons for the above phenomenon and the improvement methods are as follows:1. Open circuit caused by exposed substrate:1. The CCL is scratched before stora...
advantage:(1) It can be freely bent, wound, and folded, and can be arbitrarily organized according to the requirements of spatial layout, and can move freely an...
It can be seen that the PCB sample is flush with the substrate, meeting the requirement of height difference <15um. In fact, if the grinding process and hole...
For products where the circuit and substrate are flush with the PCB, the copper surface is thicker, usually greater than 3oz, and the line width and spacing are...
(1) Substrate: The first step in designing a cleaning process is a thorough review of the printed circuit board layout to determine plated through holes, hole a...
In an automatic insertion line, if the printed board is not flat, it will cause inaccuracies, components cannot be inserted into the holes and surface mount pad...
Dismantling method: For the dismantling of the integrated circuit, it is best for beginners to use a solder fan, move quickly along the peripheral pins of the c...
