Has anyone heard of vias cracking (barrel from pad) when being wave soldered. Was told this was a big problem by contract pcb designer, he always tent vias because of this. The reason was that the solder filling the vias caused stressing and then sep

Your area ratio for this aperture is fine (.78) usually any value greater than .66 will provide a reliable paste release. I would make sure however that the stencil is polished. I agree with other posts regarding your setup and/or paste type is prob

We just got Red-E-Set from Production Solutions for our DEK ELA printer. It is a similar concept, it's mechanical instead of hydralic or pnumatic. The print results are very good and the operators love how easy they are to setup. I am planning on
