I' ll have to agree with Dave on this one. Just get the information from the Suppliers. The Glass plate, Aluminum board, Glass slugs, etc... are all used to determine if a calibration is needed or if it was succesful.( they can also give you offset i

Read an earlier thread about using glass slugs to determine placement CPk. Can it actually be done this way? What's the procedure? Be interesting to know 'cause if it's feasible, I'd probably get myself a kit. None of us here are stat's experts a

We have problems with achiveing a void free soldered joint when we seal different kind of packages (QFP,LCC and PGA) We think the problem partly is due to outgasing from the die-adhesive (silver-glass) Does anybody have any reccomendations what to d

Try: Tungsten, tungsten carbide, ceramics like boron-nitride or how about pyrex glass? Glass blowers could make "hooks" that connect to a cross bar. I would NOT use aluminum (even if anodized). Try stainless steel 316. 303, 304 do not have enough
