Failure Mode Effects Analysis (FMEA)

Electronics Forum | Fri Apr 19 11:10:34 EDT 2002 | Steve Bondarewski

I am part of a software company looking for electronic industry feedback for the perfect FMEA software tool. Understanding how boring FMEA studies can be, how can FMEA software be improved to reduce liability and increase innovation? Basically, I wa

CMMs (Coordinate Measuring Machines)

Electronics Forum | Tue May 07 15:24:13 EDT 2002 | gregp

I believe Mitutoyo makes a CMM for that application. They were soliciting the idea at APEX show a couple of years ago. I believe they were going to develop some software to do just what you are asking for (following the IPC-9850 format). A CMM, ho

Industry Standard Naming Convention for Parts

Electronics Forum | Fri May 10 16:59:03 EDT 2002 | burguj2002

I currently create Pick&Place programs for Universal and Fuji equipment via Fujicam. I've tried to come up with a straightforward naming convention for PD's but it's not clear for some people or operators. Is there some sort of procedure or method ou

Epoxy Push Test Specifications

Au Plating

Electronics Forum | Fri May 31 06:31:44 EDT 2002 | ianchan

Recommended board finish for 0402s

Electronics Forum | Mon Jun 10 22:14:49 EDT 2002 | davef

While they're '50 pitch', you need to think of 0402 as fine pitch parts. So, ENIG, imm silver, and imm tin finishes and probably OSP would be good choices. Stay away from HASL.

Placement machine comparison

Electronics Forum | Tue Jun 18 10:42:17 EDT 2002 | Boardman

Just wondering what criteria you used to come up with Junki? Direct experience? Last I checked Juki had the lowest annual spare parts costs of the major suppliers. Not what I'd call junk.

SMT COMPONENTS

Electronics Forum | Tue Jul 16 17:03:31 EDT 2002 | stepheno

I worked for a CM in the GTA here in the GWN. Our buyers would give a techie a pile of "part substitutions" for him to sign off on. He would check out the requests and sign only a very small percentage. Some were radically different parts. I asked

Key Production Indicators

Universal Instruments charts five barriers to success 1. Nonconforming material reports 2. Parts shortages 3. Configuration changes 4. Miscellaneous - rework, software changes 5. Assembly errors

Tracking SMT Attrition (Load/Unload Loss)

Electronics Forum | Thu Jul 18 11:29:06 EDT 2002 | Mark S.

>But since we are a low volume high mix operation I need to account for almost every part used.99.5% (financial) We then also report the machine reject information on an inventory adjustment sheet. This seems to cover all the bases.
