Peter: Based on our company's experience with removing a variety of different coatings, including parylene, the BGA's can be removed. We would use a chemical etch followed by a neutralizing process. We would then reflow the devices and pry them off

I am working on an application requiring removing BGAs from a board coated with parylene. These BGAs have low standoff with less than 0.015" after SMT soldering. Can some comment on a reliable and consistent process to perform such rework? given tha

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

You will have to machine the part off down to the top of the balls. Wick solder off from individual sites one at a time. All that will be left is Parylene shell where balls once were. Take an orangestick and alcohol to break up and remove. Tricky par

In a past life I used a Swam Blaster from Crystal Mark with the media from them as well. I used it on Humiseal 1A31 and 1B31 (I think those were the products, it's been a little while). This machine and material were awesome IMO. Made CC removal a

We bought a conformal coating removal machine AKA a sand blaster at an auction. It is a CCR2000 especially made to be ESD safe. Does anyone have any experience with sandblasting conformal coating? We mostly use humiseal 1A33 and UV40. When we use the

There is a 8lb steel plate that is held down by 4 toggle bolts at the top of the machine. Its where you load the cutting media. If that plate does not have a pressure gauge built into it, contact CCR. They will send you one free of charge (at least t

We are looking for advice on removal of BGA components once urethane conformal coating has been applied and cured.

I know Micro Care made a unit that removed conformal coating with compressed air and a solvent. But they no longer make it. Does anyone have the 2000 version of this unit and may want to sell it or know of another compressed air solvent solution, p
