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

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

Have you always used xylene? For our 1B73 we use nothing but 73 thinner from Humiseal or PGMEA at about 50/50 depending on the humidity.

Update on 1B73 bubbles, Changed over to a mixture of Humiseal 73 thinner with coating (25 sec on Zahn 2) observed a reduction in bubble formation (approx. 20%) but still present.

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
