Hi Darby, No, I'm not cutting on the robot guys. I actually went thru their site and found it interesting. They truely use their knowledge and creativity, which is a rare thing to find these days. That, coupled with their common sense and resourc

Hi John, Depending on your board, it could make a difference. Copper finishes might leave that part of the pad exposed, which is a no-no in most places. Where as a HASL board prolly won't care if you pulled the print back. On the other end, over

Good morning, (1) This depends on component type. In general it would be better to have fully populated board. Or at least you should mount components with different thermal mass. You should place TC�s at three points at least: component with high t

We have fought with cut-tape way too much. It's always a bad idea. We've tried a couple methods/devices for manual splice with limited success. Before you look into this I would ask them if they could supply you cut tape qty's inslusive of fairly

We build quite a few cables ourselves, and we go through a lot of heat shrink labels. Unfortunately, we only use Brady heat shrink labels, so I don't know if I can help much. Are you actually running raw heat shrink through your printer? If so, go

Hey fellas. Listen, I'm trying to see what the industry as a whole is doing with regard to placement and reflow of the tiny QFN devices. Not the larger ones, but the 4mm or 5mm ones. We struggled a bit with a QFN24, 5mm square. The thermal pad undern

Is it a failure or a schedule overdue? If it's a failure check the vacuum sensor in the exhaust. You should be able to locate the straw and follow it back to the diaphragm. You can adjust the diaphragm. Or you can electrically jumper past it.

Thoughts are: * Eliminate solder spotting on gold fingers through process improvement in broard handling, printing paste control, and reflow recipe development. Search the fine SMTnet Archives for previous discussions. * Dispense or print a reflow te

I have an older TP9, with a programming station monitor, and a machine monitor. Both are RGB input monitors, with the cable coming from the MyData to a y-coupler on the machine monitor, and a cable running to the programming station. The monitor on

If you need any info about the 4785, let me know. If you understand Perl I'd be happy to send you the software I wrote for 4785 program generation. Mine is based around PanaPRO but it would at least give you a very simple optimization routine if
