Wire Bonding

Wire bonding – the method of mounting a chip onto a PCB There are 500 to 1,200 chips connected to each wafer before the end of the process. In order to use these chips where needed, the wafer needs to be cut into individual chips and then connected to the outside and powered on. At this time, the... Read More

Three PCB steel stencil processes

PCB steel stencil can be divided into the following types according to process: 1. Solder paste stencil: As the name suggests, it is used to apply solder paste. Carve holes in a piece of steel that correspond to the pads on the PCB board. Then use solder paste to pad print onto the PCB board thro... Read More

Why can’t PCB line go right Angle?

In PCB production, the design of the circuit board is a very time-consuming and does not allow for any sloppy process. In the PCB design process, there will be an unwritten rule, that is, to avoid the use of right-angle wiring, so why is there such a rule? This is not a whim of the designers, but... Read More

What causes black PCBA circuit board welding plate?

PCBA circuit board welding disc black problem is a more common circuit board bad phenomenon, resulting in PCBA welding disc black for many reasons, but usually caused by the following reasons: 1, pad oxidation: If the PCBA pad is exposed to humidity for a long time, it will cause the surface of t...
