These micro ablation stations can be outfitted with air ionizers and you can use less electronegative materials like corn starch as the blast media. Laser ablation works on parylene and other coatings when on metal surfaces. BWET

Is there a reason you're considering bead-blasting the conformal coating? It seems like a bit of overkill. Most of the cc that I've used over the years either has a solvent that will dissolve it, or will dissolve with heat. Heat has been our go-to

Does anyone do this? We have a small booth and lots of different kinds of media to try. it will be local stripping of coating on components for rework purposes. My main concern is ESD levels and how best to measure this. Any ideas or any papers o

Paralene, Paraxylene, or other vacuum deposited coating will require this method to remove the coatings. UR and Acrylics have solvents, as Rob above has mentioned. Plastic bead media and wheat chaff are ones that I know have been used for Paralene

Yeh due to the solvents in the coatings im guessing there is a health and safety risk. Solvent stripping is a lengthy process for the coatings we use and usually means submerging the whole board so not local to the rework. We have a booth with ioni

This is a late reply, but from my experience a really good removal station is one made by a company called CCRCo. They make a micro-abrasive station that addresses all the ESD concerns. They utilize a reusable media that is really cost effective. The

You can inspect joints using an X-ray machine and we use a sand-blaster type machine which blasts (Starch) to remove the conformal coating. (Carbo Blast). However; the inspection should be done prior to Coating, as we all know some jobs are rushed t

... continuing with Q2: How do you remove and replace? A2: Belt sander, sand blasting, grinding wheel, etc. Parylene/Paraxylyene is a great coating and can be selectively removed by several methods. The IPC-7711 (Rework of Electronic Assemblies)
