There does not seem to be a direct correlation between the PCB vias inserted into the solder mask and the copper. However, clogging with poorly performing solder resist can cause destructive results on the PCB. As a special technology of stencil printing, with the appli...
1.Questions about hole attributes In this 3D drawing, the customer designs these 2 pads that need to be opened. However, these 2 holes are defined as VIA (via) attributes, and the customer select "via hole with solder mask" when placing the order. The two p...
For high-frequency circuits with anti-interference requirements, grid copper is preferred, which reduces the risk of board warping during wave soldering in SMT. For low-frequency circuits with large electric currents, solid copper is preferred. The lin...
The blistering on the circuit board surface is actually the problem of poor bonding force of the board surface, which refers to the quality problem of the board surface. It contains two aspects: 1. The cleanliness of the board surface; 2. The problem of ...
PCB is the abbreviation of the printed circuit board, which is the basic platform for carrying electronic components to realize corresponding functions. According to the substrate material, the PCB is manufactured according to the PCB design document, and the conne...
There are two ways to distinguish the quality of a printed circuit board. On the one hand, it is judged from the appearance. On the other hand, it is judged by the quality specification requirements of the PCB itself. There are two ways to distinguish the quality of a p...
PCB design is very important in the process of the printed circuit board, which determines the whole basis of PCB. Here are some summarized points of PCB design that need to pay attention to: 1. Choose PCB board: The choice of PCB board must strike a balance betwe...
PCB is the abbreviation of the...
