Hi All, Let me summarize the key facts and findings: 1) This is not a permanent problem. Only one production batch was affected. The cleaning solution was exchanged and now the cleaning process runs normally. 2) Probably the residues are not ion

Hi All, As a result of equipment damage I have a problem with a cleanliness of printed circuit assemblies. One whole production batch was polluted by ionic residues because a large amount of hard water had been penetrated in the water-supply system

No, put a thermocouple on the heater and monitor the temperature during cleaning.

Does anyone have an equipment recommendation for stencil cleaner brand/type that they would recommend for no-clean pastes? I have used ultrasonic cleaners in the past with aqueous pastes, but I don't want to buy something that really won't work for u

There are a lot of things that might affect your cleaning efficiency. Paste type (no clean or w/s?), cleaning chemistry, aperture aspect ratio (aperture width/stencil thickness), "linty" wipes, etc. Another thing you need to look at is the frequency

It depends on the flux type. If it's water soluble, it should be cleaned soon after reflow because OA flux remains active after reflow. If it's rosin or no-clean (low-residue), then the only concern is the longer wait time, the more difficult it will
