WebThe IPC has defined a measurement method for determining whether an XRF instrument has the capability of meeting the new specification limits. The method involves performing a Type 1 Gage R&R study using a reference standard that falls within the specified thickness ranges for Au and Ni. Below is an excerpt from the new IPC-4552A publication: WebThus, to insure sufficient useable tin at assembly, the performed on the area with the longest tin whiskers identified in the minimum ISn deposit thickness of 1 micron is specified by IPC-4554 screening inspection under a magnification of 1000X by SEM.
