There's a ton of em'. We used the one from Paul N. Gardner Company, part # WF-CCD. They cost 0.95 each, so if someone decides the gage looks better in their garage, it's not that big of a deal. We set up a program that puts down 4 stokes on a test

Being a mostly-government contract house, we bought an XRF for R/I to inspect for the PRESENCE of lead in components. No matter which brand you get, they are all easy to use and relatively fast. We were very impressed with the software capabilities

Good Morning, We have 4 Mirtec machines currently. We use them in our standard SMT, Lead Free and Through Hole area's. We use them for 1st pc. pre-reflow verification and 100% post reflow inspection. I recommend them highly. We have had extremely g

we looked at the mirtec when we were selecting our AOI machine, it is a good machine, we eventually settled on an MVP GEM, comparable price but very powerful machine, we place down to 16thou pitch and 0402 and the MVP's solder joint inspection on the

No not really. They are inspected with gloves, but all PCB's are in our facility, no matter what the finish. They are stored in the same packaging material that they are shipped in. We haven't been using ImmAg for that long yet, so maybe we will se

JAX: Thanks for the reply. We did send one of the boards back to the bare board supplier and they do concede that it is black pad. When you inspect the assembled board under a microscope, you can easily move the entire solder joint away from the p

Hi all, I just wave soldered 40 boards (20 if Imm Sn and 20 of Imm Ag) using SAC 305 (in this case the wave machine manufacturer (electrovert) suggested the alloy too). plan to carry out x-sectioning to see the results. overall, just from the visual

For visual inspection table 1-2 seems to be in order here. If you can not see the bottom using 1.8 and table 1-2, it clearly would be a defect and rework would be the only option Well, my thoughts anyway, wonder if someone has other thoughts on thi

Anybody ever use SAM to inspect a bare pcb? What can you see? Is the scatter noise so bad you can't even see the copper layers? I would think you could at least see to some depth and then flip the board over. I work in a R&D environment so speed
