Thanks mikkey for this links.

I managed to find firm in Serbia that is making holes in stainless steel with high precision that is required for reballing trafarets.
From datasheets of diferent chipsets I found measures between holes and number of holes. Does anybody know what shoul be diameter for holes. On datasheet, for example INTEL FB82801EB, there is information about space between centers of soldering places 1.27mm and diameter of 0.6-0-9mm for each .Should hole in trafaret be 0.9mm in diameter or biger? What diameter of holes for 1mm; 1,0668mm; 1,118 mm spacing I need? I have to provide that information for engineer that is preparing laser cutting.

Help please master gurus:)
