You're joking rite? I mean the pitch between these two connectors is night and day. Of course you will get shorts on the 96 pin connector because your leads are right on top of each other. Now, what to do about it: You took a picture of the top o

I had one project with micro-vias in 0805 and larger pads, with no issues. But my most recent project had vias that were larger than the 0402 pads that the via was in. To the point that for a number of the lands, there was no visible pads (a couple

Hi, Those via's sure do sound large, and I think the designer must have made a mistake in the PCB design do you think? From looking at our PCB designs, if we moved to via in pad, it would really reduce the size of the PCB, so this is an important i

In my past experience, having via's under or attached to SMD lands produces risk. Solder will not consistently wick the same if it is being drawn into a via. This has also caused issues from solder wetting through the via to the other side causing a

From info I have been told from design standpoint, via in pads helps with managing EMC issues with working design, in particular for high speed digital/dense populated type PCB's. We had a manufacturing customer that had very low yield because of th

Question: We have an issue right know on a prototype batch with via in the pad on an very small pcb 50x50mm (in a panel of course). The designer has no room to move the vias as they said. The pcb is to packed with components also 8-layers. It is also

Never though an American would know about our little country beeing without a gouvernement for half a year. In Belgium, this is how law making goes: 1. First think of a rediculous proposistion. 2. Make it a law and execute it 3. Find out that is red

Does anyone out there have a method of cleaning CP6 shaft clutches that is "easier" ? I am not a fan of just pulling the shaft down and wiping it out. I like to take them apart and clean/lube them. It is a pain to get the crowns back on without rip
