When do circuit board inspection work, it is not allowed to use a soldering iron for welding. It is strictly forbidden to directly test the TV, audio, video and other equipment without power isolation transformer with instruments and equipment whose shell
We can take following 6 methods to prevent board bending and board warpage when PCB board passes through reflow furnace:1. Reduce the effect of temperature on the PCB board stress; 2. Using high Tg sheet; 3. Increase the thickness of the circuit board;
Common PCB surface treatments include hot air solder leveling (HASL), organic solderability preservatives (OSP), electrolytic gold，electroless nickel immersion gold(ENIG), immersion silver and immersion tin. Now let's learn their advantages and disadvanta
In the PCB copy board design process, the circuit schematic is often drawn based on the actual object. Therefore, the method of mastering the PCB copy board physical diagram back to the circuit schematic diagram will be the primary procedure for the desig
Six good habits benefit PCB design, details determine success or failure, learn to set rules, tthink more about others, draw a schematic diagram, carry out the circuit layout well and try to do simulation.
Reasons and control methods that may cause poor board surface quality during the production and processing of PCB circuit boards:The cleanliness of the board surface and surface micro roughness
The quality of circuit boards is a concern for people. Excellent circuit boards can help people to produce better. So what methods can we use to judge whether they are good or bad?
