The spacing and size of conductive rubber keys shall be consistent with the actual size of conductive rubber keys, and the PCB board connected with this shall be designed as a gold finger, and the corresponding gold-plated thickness shall be specified.
The larger the number of turns of common mode choke, the larger the parasitic capacitance and the worse the effect of high frequency isolation.
the copper coating on PCB, if the grounding problem is handled well, is certainly "more advantages than disadvantages", it can reduce the signal line backflow area, reduce the signal external electromagnetic interference.
In PCB board copy and design work, we often have to debug and test the circuit board, the debugging of six types of module circuit board is one of them, in order to let you better understand the debugging technology of six types of module circuit board, f
The trial-production process of six types of modules generally carried out by domestic counterparts is mainly after determining the main circuit, designing the compensation circuit, carrying out a large number of scheme design and sample production.
The copper roots narrow the line spacing, resulting in the printed board does not meet the requirements of Party A, and may even be rejected. Because the rejection will make the production cost of PCB greatly increased.
Laser marking can be a variety of characters, symbols and patterns, character size can be from millimeter to micron magnitude, which has a special significance for the anti-counterfeiting products.
The formation of residual film slagging indicates that the previous film removal process is not thorough. Poor film removal is often the result of the combination of edge film and electroplating.
The more links there are, the more likely there will be problems. This can be regarded as a very special aspect of the printed circuit production process.

The initial wiring phase uses a large 0.050 inch hole spacing in the SMD outlet and takes into account the type of package used. The subsequent wiring phase allows the holes to be positioned close to each other so that all tools achieve the highest spread
