Hi Dan, The material call outs for the 232 and 241 have been replaced by 4203 and 4 but what slash sheets are called out? 6013 will help you with the reliability but no flex circuit will withstand this many cycles.

Fellow netters. Here is a question that was posed to me this afternoon. Any help would be greatly appreciated. Dan S. This circuit board is to be repairable, and as part of this requirement, certain parts (surface mount resistors, surface and through hole capacitors, and wires) need to be capable of 20 solder cycles. The previous design was manufactured to the following IPC standards: IPC-6013 IPC-FC-241 IPC-FC-232. My question is, do these standards specify resolderability, or are there other standards that would specify resolderability? --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 15.0 To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 ----------------------------------------------------- --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 15.0 To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 -----------------------------------------------------
