We are producing boards with Alpha 591S RMA No-Clean paste and are coating after SMC with Dow silicone ( toluene solvent based) conformal coating. We have experienced several failures due to soft shorts ( electrochemical migration?) We have also obse

Hi, I need a recommendation for a manufacturer on a reasonable cost conformal coating (silicone or other). This is a US domestic appliance PCB 9 volts only that must be dipped. Silicone or other could be unused. There is a standard RJ45 socket I wher

I am doing some rework to my CCA. I then need to conformal coat the board. I'm using Humiseal 1A33 GEL and my jumper wires are teflon coated. I understand the chemical interaction between the 2 products. My question is "Is this an acceptable prac

One of the safest ways to dispose of urethane conformal coating waste is to cure it. Once it's cured it no longer is considered a hazardous waste. In the uncured state it is. We have tubes of epoxy adhesives (out of shelf life) that we do the same

Thanks Dave, sounds totally plausible. In answer to Pete B's questions 1. Spot mask IS only being applied to earthing points, top and bottom side. 2. Unsure. Speaking to manufacturer they are telling me it is compatable. However data sheet is vague.

I would suggest trying an acrylic peelable mask. In most cases peelable temporary masks are latex materials. Since you use an acrylic conformal coating it makes sense to use a mask with the same make up to avoid incompatabilities. Link to acrylic mas

Morning all, Can anyone recommend a simple low cost method to spray apply conformal coating to our PCB's. Looking for something simple, semi-automatic, and repeatable for operators to use without problems. This is a very low volume application, appro

Wood or Black Light is the common way to call that UV ligth used ie. inside "disco" and used for many applications like to activate the fluorescent particels contained by conformal coating material,adhesives, paper money, etc. Any way ask for TL-08

Hello, I want to make a simple conformal coating machine, I think in a Cartesian robot with MACH3 software. My questions are about the G-Code for the program (the software to design: % open/close nozzle, the paths (trajectory), import the pcb fi

Hi, Currently we are facing bubble formation in conformal coatings in the pcba. Have varied various specs of the conformal coating machine, even during manual application also having the same issue. the material used is silicone conformal coating. N
