Inspection criteria on PIH parts

Inspection criteria on PIH parts | 4 August, 2004

Can anyone comment on inspection criteria for PIH applications. I'm of the opinion that the inspection criteria used for wave soldered joints should be used for PIH. Some colleagues believe that a bottom side fillet is not necessary since the solder is being reflowed from the top of the board and a 75% barrel fill will not necessarily yield the same type of fillet as wave on the bottom of the board.

Any comments?

Thanks, Richard

We agree with you. Since when do failures ask themselves about the process used to attach them to the board, before failing. Smack your colleagues for us!!!
