WA Engineer, Good Morning, Your cleaning system requirements will depend on your chemistry use in production. Are you using RMA or OA flux? This will impact the requirements of the cleaning system. OA will allow you to use a DI water cleaner. If you

Density is an "implied" measurement to determine activity. Most flux suppliers can sell you a flux acidity (activity) measurement kit. I used one from Multicore a few years back. We used it once in the morning and once after lunch to monitor no-clean

Hi, We have just purchased a new rework station, i'm looking for tips to get the best quality rework possible. Currently when we are replacing a SMT component we take off the old one clean the pads with solder braid then IPA, re-tin the pads the

Hi John, Are you talking about cleaning the pallets after running to store them? or during production? well in any case...I recently started to use this cleaning solution "Cybersolv" from Kyzen. It is water soluble and also can be used instead of IP

Just a shame that the HASL fluids that are used contain Hydrobromic or hydrochloric acids or a mixture of the two and are full of strong wetting agents that are NON IONIC so the IC test results mean very little as they are checking for Ionics only. P

Blimey just seen the picture that is bad. You could try to dissolve some of the residue/gunge in IPA if it is flux residue it should readily dissolve if it is resist issue then only portions will dissolve leaving a white powder which is Talc If you

It is probably due to the solder mask being undercured and is porous alowing the flux to be absorbed which boils when it hits the solder wave that kills the adhesion. You should be seeing this only over copper traces/tracks. Reduce flux volume and in

Can anyone share some tips on cleaning pneumatic type feeders? Some feeders I have seem to be "lazy", unable to react fast enough to the the pickup heads. Someone told me to wash them in IPA, with no oiling at all, while somebody else advised to a

We used Loctite 3609 and never had problems. If memory serves me isn't 3606 a screen print adhesive? First thing I would check is the cure profile of the adhesive. If it doesn't develop full adhesion, could be problems. Nuther question is are you
