Change control in regard to AS 9100 may require following a formal change control procedure depending upon how the changes are being performed. Change control the way I've developed (and even audited to) in regards to AS 9100 are this; Significant changes will be documented and when necessary proven by first article, process validation, etc. Significant is determined by each company. For example, you have a profile for a unique product line that you wish to improve upon, you make whatever adjustments to the SMT line (temp, dwell, placement, etc) and these are typically documented within a control plan, quality plan, work instruction, etc. In this respect, a 'significant' change has not occurred and the more formal, extensive action eluded to in AS 9100 need not apply. Should you restructure your entire operation, new equipment type, new process flow, transition from leaded to lead free, those may be considered significant. Keep in mind that AS 9100 was written for the fabrication of Aircraft power plants to simple titanium hydraulic tube manufacturers. Each company has to apply this as appropriate to their operation.

Has anyone had any experience of this practice? What is the general opinion of trying to control SMT program issue status (not assembly issue but SMT/reflow program issue) using an engineering change. Is this common practice. When changes are made to the SMT, reflow or stencil print, program there would need to be an EC to approve the change. I am a bit unsure if this is workable!! Thanks for the input in advance.Douglas I McCall. _________________________________________________________________ Win 100's of Virgin Experience days with BigSnapSearch.com http://www.bigsnapsearch.com --------------------------------------------------- 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 -----------------------------------------------------
