PCB circuit board processing how to deal with burr?

Shenzhen million Chong Hing Electronics Co., Ltd. for you one by one answer!

Shenzhen Hongmingxing Electronics Co., Ltd. was established in 2003, the product categories include: double-sided, multi-layer printed circuit board, microwave high-frequency PCB, buried / blind hole high-density printed circuit board PCB manufacturing has a direct laser Imaging, high-frequency board manufacturing, characteristic impedance control, blind burial manufacturing, Bluetooth headset, flying probe test technology are the industry leader, through the company's research and development team's tireless efforts, has successfully completed the development of mechanical micro-hole, Digital backplane, high-precision impedance, Bluetooth headset, HDI and other leading production technology.

For the printed circuit board surface treatment of burrs, many times because of a variety of reasons lead to damage to the circuit board,

This will not only affect the quality of the product has affected the speed of the circuit board, if the surface of the circuit board how to deal with the burr?

There are several ways:

1. The shape of complex parts should pay attention to the quality of pre-plating to prevent the resulting replacement of copper layer;

2. Anode sets should not be too thick to prevent clogging (single-layer polyester cloth is appropriate); anode hook and pole contact between the good.

3. Regularly add hydrogen peroxide, add appropriate should be vigorous stirring; test and ensure the concentration of sulfuric acid, thereby reducing the role of copper powder;

4. Phosphorus content of the anode can not be used; anode and cathode area ratio shall not be less than 1.5: 1;

There are any PCB circuit board processing problems can consult us! High quality, low price, quality assurance.
