WebSo the general rule is that the gold-tin preform should be 90-95% of the area of the die or metallization, always ensuring, in the case of lid sealing, that the preform frame is smaller on the OD by 250 microns and at least 125 microns larger on the ID dimension. In addition, Au-Sn solder has a little quirk that is WebGold tin preform with eutectic composition (zeta'-phase and delta-phase).
