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

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

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

Hey Phil, i'm just curious what your rework processes are for your hardware after conformal coating is applied (if any). I'm interested in conformal coating as our hardware can be exposed to moisture rich environments at customer sites but to my kno
