>>> Ken Patel <[log in to unmask]> 09/18/01 11:06AM >>> All, What are the major reasons for not allowing piggy backing of the components? I know IPC-D-275 and it's replacement does not allow. I know there will be an additional rework cost but if the board is laid out and then engineering comes out with ECN that requires piggy backing of components -People here want to avoid costly fab spin on relatively low volume? There shall be some good quality and reliability reasons which I would like to know. re, Ken Patel. --------------------------------------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d 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 delivery of Technet send the following message: SET Technet NOMAIL Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail Archives Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------------
