WA Engineer, If you are able to change over to OA instead of RMA, you can clean effectively with DI water. (I know that some Military contracts specify RMA) Most systems are designed to filter the waste water of ionized contaminants before dumping t

To address the last sentence of the recent posting, Austin American Technology does have experience with board cleaners as described. More recently AAT developed a cleaning system simliar to your description called the AquaBatch. The AquaBatch was

Knock off some balls and you may find it has a flat bottom to it were it has mechanically stuck to the solder resist usually seen under 60X magnification. Common with Liquid photoimageable resist (I know again) Best way to check resist cure is to pay

I have also seen this before on a CP6. We had an issue once on a CP where the shaft was coming down too far at stn 1 for pick up and forcing the nozzles up and sticking in the windmill. Check that the correct spring type is being used. Also, maybe

We're not familiar with your DYMAX #984-LVUF. The problem is not with your conformal coating. The problem is with your 0805 [and not all of 0805, probably just those from a specific supplier]. This lack of coverage of components is called dewetting

We received about 5K assembly boards from china. They left flux residu on top of the board and the flux they use was different than us. RESULT ... we use a translucent cylicon to cover the board and it was not possible to dry the cylicon because of

We have an HSP 4796B chipshooter on the floor. Feeder pick-ups after changeover (during new run start-up) are always a bit of a hastle. Can anyone tell me if a feeder "zeroing" jig works well? I always reset feeder B offsets. I recorded "B" offse

Hello, I have a question on white residues formation at wave soldering. We have recently run experiments to test the performance of various halide-free water soluble fluxes (ORH0 under JSTD-004). The flux was applied through a spray fluxer and all P

Your problem is not the 0.4 pitch. Your problem is the manual cleaning. Manual cleaning will only remove the solder paste from the surface of the stencil. What's more, manual cleaning will force additional contamination into the 0.4 pitch apertures
