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

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

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

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

Alternatives are: * DSCC Columbus continues to maintain the QPL for MIL-I-46058C. [Engineering is unlikely to change.] * Use International Electrotechnical Commission Standard, IEC 61086 - Coatings for loaded printed wire boards (conformal coatings)

Many companies use IPC-CC-830B as a replacement for the deactivated MIL-I-46058 conformal coating standard.
