  As an important part of modern electronic equipment, Switch pcba board is an information carrier that integrates various electronic components. It has a wide range of applications in the electronic field, and its quality can directly affect the performance of the product. In the traditional inspection, the Switch pcba board mostly relies on manual visual inspection, and in the inspection process of the Switch pcba board manufacturer, it is inevitable that people directly touch the Switch pcba board with their hands.

  What harm will it bring to directly touch the Switch pcba board? When touching the Switch pcba board by hand, if you don't wear special gloves, fingerprints will be left, which will cause the bad scrap of the Switch pcba board and reduce the reliability of the end user.

  Disadvantages of finger prints in the manufacturing process of Switch pcba:

  1. The bare hand touch board before the solder mask of the Switch pcba board will cause the solder mask to go down, resulting in poor adhesion of the green oil, and it will bubble and fall off during hot air leveling;

  2. In the process of the immersion gold circuit board after soldering and before packaging, touching the surface of the circuit board with bare hands will cause the surface of the circuit board to be unclean, resulting in poor solderability or poor bonding;

  3. When the bare object of the Switch pcba board touches the circuit board, a chemical reaction occurs on the copper surface of the board in a very short time, resulting in oxidation of the copper surface.

  4. Printed wet film or silk screen printed circuit and the board surface before lamination have fingerprint grease, which can easily cause the adhesion of dry/wet film to decrease, lead to the separation of plating and plating during electroplating, and the gold plate is easy to cause the board surface Pattern, after the completion of the solder mask, the surface of the board is oxidized, and the color of yin and yang appears.
