Thank you for all of the advice. I am using the extended spray for these cards. Humiseal have recommended using their own thinners 600 instead, so will run some trials with this and also the humiseal pre-mixed material (at the moment we mix our ow

I am looking into replacing another business division's Acrylic coating process with our Urethane coating process. Unfortunately, MIL-I-46068 doesn't differentiate AR/UR's performance, and the MFR data sheets don't match up at all (they each spec di

We us a lot of 1B31 it could be one of the most common coatings out there. We do not clean the boards and do not have an issue. I would check the solder mask compatibly. I would also see how the 3rd party company is testing the boards what criteria o

In a past life I used a Swam Blaster from Crystal Mark with the media from them as well. I used it on Humiseal 1A31 and 1B31 (I think those were the products, it's been a little while). This machine and material were awesome IMO. Made CC removal a

We currently have an assembly that we have to mask the surface of several (24)SMT components where thermal compound is applied at a latter operation. These component packages vary from BGA's to QFP's. After the thermal compound is applied the PWA is

My company recently aquired an asymtek coating machine and I have been using Humiseal 1B31, an acrylic coating, in it to coat all the boards given to me. They have now come to me and asked if it is possible to run Humiseal 1A33, a urethane coating, t

Hi All, Recently we are working on the conformal coating process using Humiseal chemical 1B73 and thinner 521. Bubbles on component body/joints are seen after gone through the IR Reflow Oven. During the conformal coating, only tiny bubbles seen af

Once the HumiSeal conformal coating has been applied to the printed circuit board it is usually best to allow the material to reach a touch-dry stage, before heating the board to accelerate the cure schedule. This avoids potential problems such as bu

totally wrong. a. I do not reccomend Humiseal UV products. My Dad started Humiseal. b. As the former VP of Dymax Corporation I know quite a bit about this subject. Contact Dymax in Torrington, CT and inquire about 984LV. c. You will definetly sleep b
