Tom, All of the slash sheets in IPC-4101 that correlate to those taken from MIL-S-13949H reference the MIL-S-13949H slash sheet number. If you have IPC-4101, you can find these listed in the Slash Sheet Index or on the applicable slash sheet under ID Reference. Please let me know if you have any further questions. Best, Chris Chris Jorgensen Project Manager IPC 2215 Sanders Rd Northbrook, IL 60062 -p- 847-790-5328 -f- 847-509-9798 [log in to unmask] >>> "Tom Kropski" <[log in to unmask]> 10/01/98 06:54AM >>> Chris, I've seen many emails regarding the replacement of mil-s-13949, but never any list of replacements to ipc-4101. Is there a guide to what slash sheet from mil-s-13949 correlates to the slash no.s in 4101?
