There are a number of processes needed to fabricate a bare PCB and each one takes money and time. Smaller is Better In the early 2000s the first fine-pitch ballTo do this without the solder going through the hole I would use copper capped vias, also called blind vias, which now seem to be a quite common design practice. 75:1. With via in pads there is the issue of having sufficient solderpasted to fill the via hole during the reflow process, which can cause a lot of problems, for instance, skewed parts, tombstoning, etc, JLC will not take the consequential responsibility due to this. These four items are considered when we determine the data: SMD component to component spacing. The diameter of the solder mask opening should be double the diameter of the bare copper for the fiducial. 3 mm, BUT smallest drill hole size is 0.
