How to improve the appearance quality of PCB solder resistance

how to improve the appearance quality of the printed circuit board flux resistance has become an urgent problem to be solved in every PCB factory. Factors that affect the appearance quality of solder resistance

Basic design of solder resistance

Double-sided PCB extends from the substrate surface to both sides are composed of line layer, solder resistance layer, character layer, and through the drilling layer through the top bottom line to achieve connected electrical ventilation. In the actual p

Explore PCB circuit board solder resistance layer and solder paste layer

Solder resistance coating is a kind of protective material suitable for the exterior surface of circuit board. The solder resistance coating will cover the entire surface of the board, including metal and dielectric materials, except for the pads and hole

The difference and function of PCB welding aid layer and welding resistance layer

Solder pad refers to the part of the board to be coated with green oil. In fact, the solder mask uses a negative output, so when the shape of the solder mask is mapped to the board, it is not green oil solder, but exposed copper. Usually in order to incre

11 Uses of 0 ohm resistance

0 ohm resistance is the resistance of 0 ohm, used in PCB design and other aspects, is a kind of ideal resistance. Zero ohm resistance is not no resistance, it's just close to zero ohm. How much current can be passed through the 0 ohm resistance of each pa
