Differences between multilayer PCB and single panel / double-sided PC The biggest difference between multilayer PCB and single panel and double panel is that the internal power supply layer (to maintain the internal power layer) and the ground layer are added. The power supply and ground wire network are mainly wired on the power supply layer. However, the multilayer wiring is mainly the top and bottom layer, with the middle wiring layer as a supplement. Therefore, the design method of m... -

The difficulty of laminated structure of mixed press PCB One of the major challenges in RF/microwave applications is how to ensure that the actual tolerances are within the design tolerances, so as to achieve the desired operating frequency. One of the biggest challenges in the lamination design of mixed-pressure structures is to have uniform thickness between different panels or even between different pieces. Due to the existence of a variety of substrate material types, there are a variety ... -

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... -

Crack problem of inner thick brazing pad The demand for heavy copper PCB is increasing, and the inner layer pads are getting smaller and smaller. The problem of pad cracking often occurs during PCB drilling (mainly for large holes above 2.5mm). There is little room for improvement in the material aspect of this kind of problem. The traditional improvement method is to increase the pad, increase the peeling strength of the material, and reduce the drilling rate, etc. Based on the analysis...
