Thank you for your response. I appreciate all anyone can provide to help with this. I have no manuals to use. I inherited this task when the usual operator dropped dead the other day. He was the only one who ever ran this machine. I was able to print

Hey Thanks! Yep, they are pricey but I think it would be a worth while expense to safegaurd $250,000 worth of leds! I will tell the powers that be and see if I can squeeze out some cash. If I scrap one loaded board could I use it for profiling 20 to

There seems to be less play in the pocket than with other parts i've loaded. I was assuming the large nozzle would work better but for reasons unknown to me it didn't. I also tried a 1mm and had parts all over the machine (can you say hand place 100+

I guess no one at ECD reads this forum. They make a clip-on thermocouple prob. Where I used to work we had 3. At first I thought they were very awkward to set up. But once you practise a bit and get used to the right hand thread tightening screw

Crappy piles? Weren't they a hard rock band in the 80's? I know on most of our boards the little silk screen dot is just the component identifier in really small font when looked at in Gerber. But this dot isn't very big, so I see how it can affec
