Nordson ASYMTEK engineers are familiar with the regular 1A33 but the gel is a relatively new product. Its purpose is to prevent the exact problem you are describing. Can you provide us a phone number so we can discuss in person? You can send the phon

hey, thanks for the advice. We have replaced all the lines and have had the valves cleaned & rebuilt, so we are hoping that will be sufficient. What does the dewetting of the urethane coating look like???

I would also suggest looking at your ramp rate in the cure oven. We noticed that accelerated heating increased the "gas out" of the solvent. We run 1A33 and and do not exceed a .5/degC ramp rate.

what we are getting is open circuits not every BGA is failing we use Humiseal 1A33 and currently there is no masking instruction for around the BGA

We have PVA 350 benchtop dispensing equipement with humiseal 1A33 CC material. is there any moisture measurement process in conformal coating material?

Good morning Mark, No issues around the masking at this point. The issue seem to be in open areas as well as between clad runs. We are using Humiseal 1A33 Conformal Coat.

Dear Mike, I've forwarded your question to the experts at Nordson ASYMTEK. I believe most of the team are on leave for the holidays, but hopefully we'll have an answer for you next week. Thanks!
