Gold, silver and copper in the popular science PCB board

Printed Circuit Board (PCB) is a basic electronic component widely used in various electronic and related products. PCB is sometimes called PWB (Printed Wire Board). It used to be more in Hong Kong and Japan before, but now it is less (in fact, PCB and PWB are different). In Western countries and... Read More

The destructive analysis of laser coding on PCB

Laser marking technology is one of the largest application areas of laser processing. Laser marking is a marking method that uses a high-energy density laser to locally irradiate the workpiece to vaporize the surface material or cause a chemical reaction to change color, thereby leaving a permane...
