Software to test

Electronics Forum | Sat Jan 08 00:47:15 EST 2005 | rodionp

Hello, I was wondering if anyone of you would like to test our software before we go release. The plan is to release that soft some time before March 2005. But before that I want to get people to use it with hopes that they will "brake" something...

Touch-up and inspection of visual defects

Electronics Forum | Wed Apr 27 11:43:32 EDT 2005 | patrickbruneel

Hi Daan, What we did in the time was pareto analyses on all board designs to determine the critical areas (mainly design errors) and only inspect those specific problem areas. Every batch had a copy of the PC board with problem areas marked and only

FUJI Line vs MY15 line

Electronics Forum | Thu May 26 12:21:04 EDT 2005 | stepheniii

We have dek-my12-my12-heller. We are very happy with it. Change-over time varies more by facility than by machine type. I worked at a place with dek-mviif-msf-btu and we had faster changeovers there. There we had a dedicated feeder set-up. Close to

All good points and thank you for your replies. Most of the components lost are discretes. The problem I have is my operators gather any SOIC "lost components" and return them to stores in a small metallised bag. This in turn goes into a 16" X 12" X

New SMT line - Need equipment selection help

Electronics Forum | Thu Jun 29 23:54:06 EDT 2006 | grantp

Hi, I think it's a good choice for a startup, and if your finding it's accurate enough. We only went Fuji because of our volume, and small errors were adding up, but if I was starting from nothing again it would be MYDATA because I could not afford

Stencil thickness

Electronics Forum | Thu Jun 09 13:30:34 EDT 2005 | PWH

I would suggest 7mm thick "Durostone" as a carrier material. Cut lip/pocket for PCB so it is 0.05" thinner than thickness of PCB. Allow 0.010" gap on all sides of PCB. Machine lip to width between 0.050" and 0.100" to support under perimeter sides

HOW TO REDUCE MACHINE SET-UP TIME???

Electronics Forum | Fri Jun 10 10:49:06 EDT 2005 | jbrower

Hi James, As my companys process/manufacturing engineer, I set up a program that dramaticly reduced machine down time. Some base numbers; we went from an average of 4-6 hrs set up on our Mydata to setups of under 15 minutes on average and some belo

Rheometric Pump - Yes or No???

Electronics Forum | Mon Jun 27 14:15:23 EDT 2005 | Bob R.

We have a couple sites (out of over 150 lines) that use them. The site that picked them stands by them through thick and thin. Any time they have problems they blame it on the paste, even though paste from the same lot will be running great next do

Lead Free and Leaded Process Mix

Electronics Forum | Mon Jun 27 09:09:19 EDT 2005 | Bob R.

We've all been soldering Pb free parts for a couple decades. All your surface mount capacitors have probably had a Sn finish for years. Whenever one of our parts with a SnPb finish converts for Pb free we have the manufacturing site do a small buil
