I read through this thread somewhat and checked out the pictures. I've programmed TH lead checks on a newer Yestech and an older Mirtec. I personally use the Yestech white-top/histogram check and the only solder inspection Mirtec has. In my experienc

EricR: Regarding "*** By the way, since we have used the Tin-Silver-Copper lead free solder there has been a strange liquid type chemical leek from the oven exhausted pipes." ... I don't know anything about your process, but the first thing I'd inve

Ok, I have an issue that is somewhat uniform in it's recurrence in that it keeps showing up on the same location on the board. The problem area is a group of traces on the exposed side, that keeps having solder mask peel occur. As you can see in the

Dear JSK, It sounds like the root causes of your problem are two fold. First, excessive heat will polymerize the abietic acid found in rosin forming neo-abietic diamers and polymers which are much less soluble than the parent monomer. There are

Steve: I thought Kyzen products were "additives" to either aqueous or semiaqueous inline or batch machine cleaning processes. I'm trying to clean the no-clean residue from a few components that can not bear to see water. Can you use Kyzen products

| We recently made the switch to no-clean and the wurface mount is turning out beautifully. However, the wave solder process continues to put up a fight; we are getting a white residue on the surface of the PCB. The residue is not localized to

Well... Some are worse than others... How can you identify that it is caused by uncured mask and not flux residues? The flux is from indium, 3592. Some research in their tech library revealed that either Kyzen or Zestron would work, which is the re
