Hi, Please comment: We have a problem in our wavesoldering process; Vias are too close to each other, and solderbridges occur. The width of soldermask between vias is only 0.2 mm, ( 0.008" ). Hole size is 0.4---0.6 mm ( 0.016"---0.024" ) Sometimes it is a must to design vias in parallel with the solder wave. What is the minimum width of soldermask between vias so that bridges can be avoided ?
