Where is the best place to buy Humiseal 1A33 in gallons?

Hello , We are using Kester 959T flux and we wish to purchase Aim Ws 716 flux, due to higher activity. We also use humiseal 1a33 for conformal coating. Is anyone using Aim flux and humiseal 1A33, are they compatible ? Thank you for info

Hello @ the specialists, we have a Nordson Asymtek SL940 to coat our pcb's. We can use the valves SC100 and SC400 for conformal coating applications. We use the Humiseal 1A33 as the conformal coating. Now we would like to use the standard 1A33 in th

We doubt that Humiseal 1A33 is causing opens in your assemblies. We'd guess the opens occur earlier in the process, but are not hard failures. So, you pass your tests. When applied, the conformal coat flows into the gap in the ball crack and insulate

Well, since you're looking at a water soluble flux from AIM, I'm guessing you wash the boards before you conformal coat them. Thus, I wouldn't expect any interaction between the excess flux that you're washing off of the boards and the Humiseal that

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

Silicone contamination could appear as fisheyes or dark spots under UV light. 1A33 can be heat cured but is a single component oxygen cure coating - it needs a source of oxygen to cure. An unvented oven may slow or limit the cure. Check out the TDS

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.
