What if you were this guy [PeteC] and you knew this batch of boards had some goofball issue that messed with product quality, increased rework and all that AND you still had to run them? I've had to eat from the pie before. I'll bet you have also.

Hello guys, first of all I would like to thanks everyone for their posts. I really appreciate it. We are now communicating with vendors about damaged boards. And something about the analysis of damaged boards. We have not yet done, but we are trying

Peter, Based on the images, it looks the HASL is too thin. I have seen this a few times when the pcb supplier uses too aggressive of a process to remove the solder. This can lead to oxidation of the underlying copper. An XRF of a pad that won't take

I'm putting together a spec for testing solder tips for resistance, voltage leakage, and temp tolerance. I've found solid numbers for both max acceptable resistance and voltage leakage, but nothing for max temp tolerance. Anyone have values they're

Just Essemtec, unless one of the many non-jetting machines used from Nordson or Camalot etc would work for you. Of course just because the paste you want to use is not supported doesn't mean, given your "cost is no object" approach, you can't have so

This is usually a standard part of a machines toolkit if you have paid for the (probably optional) software packages that handle data input. However you've already said you are using Excel, so why not flip the data in there, its not a huge mathemati

If it is "wondermask" made by Techspray, it is supposed to be water soluble. It being overcured (we have experienced this before), water will not touch it. We used acetone which softened it up to remove it with an orange stick. We apply it ourselves

Use a solder pallet, the pallet will mask off the locations required, thus eliminating the need for any kind of masking!! You've eliminated the need to apply, but you still have to peel off, not much of time saver. Pallets can be used for batch or s

I think you'd better create the BOM list first and clarify what kinds of components you want, then you can contact the assembly supplier for quotation, just remind them to use the cheapest one, many Chinese supplier can offer very attractive price fo
