      Half hole technology After the PCB is made in the half hole, the tin layer is set at the edge of the hole by electroplating. The tin layer is used as the protective layer to enhance the tear resistance and completely prevent the copper layer falling off from the hole wall. Therefore, the impurity generation in the production process of the printed circuit board is reduced, and the workload of cleaning is also reduced, so as to improve the quality of the finished PCB. After the production...

      Why are multilayer boards mostly even? Due to the lack of a layer of medium and foil, the cost of raw materials for odd PCB is slightly lower than that for even PCB. However, the processing cost of odd layer PCB is significantly higher than that of even layer PCB. The processing cost of the inner layer is the same, but the foil/core structure significantly increases the processing cost of the outer layer. Odd layer PCB needs to add non-standard lamination core layer bonding process on th...
