Humiseal 1A33

Electronics Forum | Tue Feb 24 09:47:45 EST 2015 | rgduval

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

BGA failure after coating

Electronics Forum | Thu Oct 01 07:03:55 EDT 2009 | davef

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

Clean before conformal coating?

Electronics Forum | Thu Jan 04 17:26:17 EST 2001 | Cory

We're going to begin conformal coating a few of our assemblies as required by our customer. We're using Kester No clean paste and will use cotton gloves to keep the boards clean while handling. My question is: Do we need to clean the boards prior to

Conf.Coating - Humiseal 1B31LOC vs. 1B31

Electronics Forum | Thu Jul 29 00:50:37 EDT 2004 | C.W

Anyone has experience with Humiseal 1B31LOC and 1B31? Their material properties(physical, chemical, temp. etc) are fairly much the same after cure but there are some differences when they are at liquid stage. We are currently using 1B31 but is planni

Conformal Coating Dilemma

Electronics Forum | Tue Jul 26 11:02:30 EDT 2005 | dphilbrick

I have a single sided PCB that contains 4 RF connectors that will require conformal coating. Sounds easy, well the RF connector is .080 in diameter and stands a whole .050 in height. The sub-straight that the barrel sits on is about .020 thick. I don

Conformal coating mask dots and halos

Electronics Forum | Thu Feb 25 07:37:42 EST 2010 | pcbrown

We are using Humiseal 1B31 and polyester dots for masking. We are spraying this in a Binks sprayer mixed at almost 1:1 with 521 thinner. Whe are seeing the coating creating thin halos around the poly dots as if the dots are "rejecting" the coating. T

Acrylic conformal coat cure test method

Electronics Forum | Wed Feb 28 20:10:08 EST 2001 | mhunter

Checked the archives with no luck. Anyone have a reliable test method of verifying acrylic conformal coat cure. Using Humiseal 1B31 mixed with approximately 30% solvent, spraying with a Nordson. Thanks in advance.
