The purpose of gold deposition process is to deposit nickel gold coating with stable color, good brightness, flat coating and good solderability on the surface of printed circuit. It can be divided into four stages: pretreatment (degreasing, micro etching, activation and post leaching), nickel precipitation, gold precipitation and post-treatment (waste gold washing, di washing and drying).

The difference between the sinking gold and the gold plate of the PCB

The sinking gold plate and the gold-plated plate are commonly used in the current PCB production process. With the integration of IC more and more high, the more IC feet more dense. and the vertical spray tin process is difficult to become a fine solder plate blowing smoothly, this will bring the SMT placement of the difficulty; In addition, the service life of tin-spray plates (shelf lifetime) is very short.

Wireless routers, like other wireless products, RF (RF) systems, need to work within a certain frequency range, can communicate with other devices, 2.4GHz is the early wireless router widely used in one of the frequency bands, penetration high. So, when searching around the network, sometimes you can see dozens of wireless signals, which is like driving on the road, two lanes to go dozens of cars, each other is inevitable impact, this is the channel interference we often say.

Heat dissipation skills of PCB

The heat generated by the working of electronic equipment makes the internal temperature of the equipment rise rapidly. If the heat is not dissipated in time, the equipment will continue to heat up, the device will fail due to overheating, and the reliability of electronic equipment will decline. Therefore, it is very important to heat the circuit board.
