      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 of P...

      About Multilayer PCB 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 multilayer. PCB is basically the same as that of d...

      Advantages Of The Plug Hole 1. The plug hole can prevent PCB through the wave soldering tin from the through hole through the component surface caused by short circuit; That is to say, within the scope of the wave soldering design area (generally the welding surface is 5mm or above) there is no hole or hole to do plug hole treatment. 2. The plug hole protects against possible short circuits caused by closely spaced devices such as BGA. This is the reason for the hole under the BGA to keep the...

      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 of c...
