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

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)

Try by using hot air (narrow nozzle) blasting the chip body until it gets released. Regards.....GS

You can try strip it with Chemically (like Acetone) or micro-blasting.

I agree that the tines (webs between apertures) can become damaged on fine pitch stencils from a blast of air. If they get bent, the stencil won't seat and gasket properly allowing bleed out of paste. Of course we all know that the air being blasted

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

We've never tried to remove Paraylene from a BGA, but we stayed [in seperate rooms] at the Red Roof Inn. Parylene/Paraxylyene is a great coating and can be selectively removed by several methods. IPC-7711 (Rework of Electronic Assemblies) has a sect
