Using a bad-board pallet marker has been used successfully and is a method that keeps the pain off the assembler during placement. Much depends on the programming capabilities of your equipment but most should handle it. Have your layout people number the array and add the marker detail. The number of xouts seems to diminish the return over 50%. We frequently see an allowable xout directive as 50% of the array, but not more than 25% of the pallets shall have xouts. This could provide a balance from fab to assembly and keep all costs down. --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 1.8e 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 847-509-9700 ext.5315 -----------------------------------------------------
