I've recently been placed in control of operations of our SCS conformal coat sprayer and I must eliminate problems with wicking of humiseal 1b73 into surface mount connectors while also trying to minimize masking as much as possible. We use a 55:45

Here is a posting by P Kinner at Humiseal ... Typically, there are three main approaches to avoid coating wicking into press-fit connectors (and other keep out areas). Wicking is a phenomenon caused by a combination of low viscosity of conformal coa

Hey all, we will be starting to coat our PCB's soon. I am looking for info on what type of UV light is needed to inspect the boards. We will be using Humiseal 1B73 Acrylic coating. TIA, JD

It's weird that it would be just 0805. When we see this it relates to a single part number and it goes way after a time. We use a Humiseal 1B73. I've emailed you the contact for a person that is very knowledgeable on conformal coatings.

I am new Engineer in conformal coating and I am looking for help with dewetting. What "Tricks of the trade" can I try to reduce or eliminate dewetting? We use a lot of Conap CE 1155 and Humiseal 1B73? Any help would be appreciated!!!

Humiseal recommends a 1 to 1 mix ratio of 1B31 and Thinner 521. I have for that I need to thin my ratio more to get humiseal to spray correctly in our PVA650. Also I am using Humiseal 1B73 but the tech data sheets say the same for spraying. Try thinn

I use Trace Labs and certainly recommend them. I actually just had this test done last week. Adhesion test per ASTM-3359 Method B. We also use Humiseal 1B73, which is similar to the 1B31 you use. Is your soldermask "active" enough for this coat

Hello to all out there, We're considering CC process,and would like to know some defferences between SSC3 of Electrolube and Humiseal 1B73, yes,I know that SSC3 is silicone one,and Humiseal 1B73 is solvent based acrylic as well as other basic propert

A while ago I tried using rubber boots for masking but couldn't get them to work because the coating we use (Humiseal 1B73) is so thin it leaches under the rubber. If you can get them to work with your application more power to ya.
