Is there any relyable to hole a chip if functionality isn't a concern? A few months back one of my coworkers tried making a p4 keychain with a dead cpu. He busted a good drillbit trying to drill it and then borrowed a plasma cutter to try burning a hole. All he got for his trouble was a scorched spot on the surface.
Long ago at a then small, now enormous semiconductor company, a colleague of mine had need to drill holes in the ceramic lid of CerDIP packages, for a hoped-for production conversion of a stock of hundreds of thousands of units. He found a method, (not only for that, but for the "secret sauce" reason for doing it). I think he used a laser--must have been a pretty energetic one--not likely one in your home shop.
My employer's got a decent machine shop for prototyping/destructive testing purposes (where I suspect the plasma cutter was accessed), but afaik no industrial lasers.

So far I've crunched some hundred units with S40 without any problem.
I'd say it is ok to say this version is stable.
