Hi all, We've had a Yestech F1 system for several years now. Overall we are happy with the machine, fast and easy to program. Good false call rate and few misses. Now for the issues. We have two in particular. 1. Software crashes - these general

Hi Graham, I've worked in the industry selling EnSolv, Lenium, and now ENTRON solvents, which are all based on stabilized NPB. These solvents do not always clean the no lead pastes. The problem is that the pastes are becoming more like adhesives,

I work with a small EMS shop that has extremely good capability because I created it for an R&D Lab for the U.S. Army. We have at times discussed leasing the equipment/facility to other companies who prefer that to farming out their work to an EMS.

This is just an example of what we do at our facility. We record cycle times of the "cells" the operators work in, they are divided into load time, robot time, tester, and packout. Generally I let the operator complete the process about five or more

Thanks ISD, I had a look at those papers from Freescale regarding the LGA "optimal zero-g offset after PCB mounting". Had me going for a while until I realised it was in relation to the finished product. Hmmmmm. LGA/QFN type. They can be a little t

Hi again Bobpan, One thing I noticed when I pulled the z-rod to inspect it was that it was "bearly" finger tight. When I replaced it, I snugged it a bit better (not overtightening). After resuming setting up additioanl placements (this board requires

Thanks again Bobpan for all of your help. I hope some of my questions are dumb ones. Regarding "first", the QA error 0, you were right. In checking the setup, for some reason theta was 65227 instead of the 0 that I thought I had set. Regarding "sec

Hi Bobpan, Regarding "second", the results of the test are no difference - still rejects the part. I tried 2 mils, 3 mils, 5 mils, 7 & 9. I changed the tolerances fron about 15% to 20%+. By the way, I did put on the new nozzle and it is still the sa
