PCB circuit board design solder joint is too dense, easy to cause wave welding, solder joints leakage. Here we analyze the design of PCB solder joints under the optimization of the way too tight.
An analysis of the optimization method for the design of PCB circuit board solder joint
Analysis: this board plug-in components more, relatively dense. Because the distance between the solder joint and the solder joint is 0.3-0.5mm, it is easy to cause the continuous welding, and because of the poor quality of soldering flux, it causes a lot of leakage in the south.
Countermeasures: to increase the distance between solder joints, intermediate solder oil increased. Strictly control the quality of flux.
Thinking: the design of a more dense PCB circuit board, as far as possible a small range of density, can pull open as far as possible. Such as the safe spacing of PCB, although 0.3MM, but can be done as far as possible to increase the 0.6MM to more than 0.6, so the probability of the problem will be greatly reduced.
