IPC-7912 for end-item DPMO is about two years old now; IPC-9261 for in-process DPMO was published several months ago. The IPC DPMO 5-22g committee met two weeks ago and has generated a revision to 7912 that will be balloted in about a month; need to go through a public announcement of the proposed standard first. No changes in formulas but the examples were clarified and document layout changed for ease of use. We (IPC) frequently get requests for "typical" DPMO numbers so users can assess themselves against industry. It's been a challenge to get anyone to offer up numbers so we can build a benchmark. It's considered proprietary info and companies seem to be concerned that their numbers will be used against them by competitors. We're exploring ways to do this in the blind, perhaps through our TMRC or EMS Council. In the meantime, Bob Willis and the SMART Group in the UK have already started gathering numbers. SMART keeps referring to it as PPM but references 7912; Bob will have to tell us if it's truly DPMO as defined by 7912 so we'll know if their numbers are apples to apples. If we can set up a program that satisfies company confidentiality concerns and you'd like to participate, please reply to me off-line (it helps with the privacy stuff you know) [log in to unmask] Cordially Jack >>> [log in to unmask] 05/29/02 03:15PM >>> Hi Ron, There was an activity within the IPC termed DPMO which is a TLA for Defect Per Million Opportunity. The original intent was to accomplish what you asked for, comparing apples to apples. Off the top of my head I believe it was IPC-9261. Hope this helps, Mel Mel Parrish Director of Training Soldering Technology International 102 Tribble Drive Madison, AL 35758 256 705 5530 256 705 5538 Fax [log in to unmask] www.solderingtech.com -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of Dieselberg, Ron Sent: Wednesday, May 29, 2002 12:57 PM To: [log in to unmask] Subject: [TN] One of our Quality Managers has asked me to quiz the TechNet for information on solder defect rates. We think we are pretty good and want to compare against others in the industry. He has asked for rates for hand soldering and also machine (automatic) soldering. We deal in two basic product lines; IR products and Space/Communications. Any information regarding solder defect rates in the hand soldering and or automatic soldering areas would be appreciated. Thank you.
