Anyone have experience printing solder paste for a Toshiba SSM3K15CT(TPL3) FET with CST3 package? Using 1 to 1 rectangular apertures with a 4 mil stencil and Alpha OM 338 #4 powder size lead free solder paste. Print head speed is 15 mm/sec and solven

Hi guys, We have an interesting case we haven't seen before (see the picture below) http://postimage.org/image/lu2f4ae55/ Solder balls form on unpopulated pads after reflow. 1. Reflow profile is fine. 2. Stencil thickness / paste volume is also f

Hi MikeS, I didn't post all the information, because I didn't want to mislead you. I wanted to see your way. We tried 3mil and 4 mil stencil using type 4 paste. It was hard to get the right aspect ratio and that;s why we did it on Nickel stencil - a

Hi, We are having a problem with the interpretation of the surface evaluation criteria of J-STD-003 section 4.2.2.4.2. "A minimum of 95% of each of the surfaces (i.e. each pad) being tested shall exhibit good wetting. The balance of the surface may

Hi all. I used a 5/16" white paper sticker to mark a reject PCB in a panel of 10. One of my my Quad 4Cs sees it O.K. and marks the PCBs reject. The other machine either shows them all reject or shows the marked one as good and the other 9 as rejec

HI! We have a QUAD 4C since 8 months . Yesterday the head remained immobile in the position where it put the last component to complete a board and indicates Motor Error # 5 (SRX engine communication time-out) and I don’t know what it means and ho

We have two QUAD 4C working in tandem. 3 months ago the EPCU battery (QUAD # 2) died, then we change it. Then downloaded the MODs from the controller to the assembler(does simultaneously on both machines). All this time we continue to work normally.

Hi: Our machine (QUAD 4C) has a CyberOptics laser 6604033; when initialize at HOME, z-rod descends and doesn't retracts, which makes me think that the laser is misaligned, here's a link to the video recording: http://www.youtube.com/watch?v=W9ma7Zsf

I have been using Quad 4C's for 15 years and have never come across this error. Everything initializes OK but when I start a program through Central Controller I get an "OUT OF MEMORY" error. I have flushed the Mod codes and re-entered them and have

It could be PC Memory or maybe a full hard drive. I would check the following first. 1. Reset board count (there is a bug that causes problems if the count gets too high.) 2. Make sure ROA=OFF if the line is in your configuration file editor. 3. Ma
