Yes, I can see your problem, the nozzle makes only good contact in the center and so the ends don't make good contact. The ends tend to curl up during reflow. There were two suggestions to solve this. 1) Let the operator push down the labels befor

Help! Does anyone know how to get a Camolot Gem II machine to put down dots for 0402 placement? I have been working with Electrovert Tech's that say their machine WILL place dots for 0402's. I have reduce the speed of the pumps to half the speed,

The two first level cuts at comparing placement machines are: * Placement rate * Range of component capabilities This boils-down approximately to machine price. Virtually, everyone's feeders are priced similarly. Go to "Circuits Assembly" magazine

We do use a company for custom fixtures, but we also make some in house. The biggest hurdle for a board that requires a fixture to go through printing and SMT is that the board has to be the tallest thing. So any hold downs or locating hardware has

Thanks to the emails and posts I've read I think I've narrowed the problem down. Its a Netscape issue (which is why when people first initially said they were having problems it was working for me.) I'm working to resolve the issue. In the mean ti

Barry, We have two of the MV models, one that we bought second hand, and the other new. The " i S " means inline? We love the MV's, which are offline, semi-auto, vision aligned. Just a great machine. Simple, intuative software, all parameters easy to

You have to be careful here. The figure is expressed as placement accuracy, not process quality therefore 3 sigma does not relate to 2700 PPM defects but 2700 parts per million placed outwith 15microns (0.0006" / 0.6thou). Extrapolating the distribu

Hey MoonMan, Did I catch in one of your fabulous threads that you're using Tetra stencils? I'm anxious to find out how you're liking them. We we're all set up to go to Tetras, then mgt decided to close down our factory - Dooop! "Foiled" again! (te

Pete, I started with the App engineers, they had me try a 21g needle then a 23g needle then a 25g needle. The tech's are the ones suggesting that I slow the pump down to half speed and try a 27g needle. The needles are $150 a piece.....I now have

We have been pretty successful with screen printing glue, however the smallest component we now glue is a 0805. We had many problems using our Gemini II to put down glue dots for a 0603, so we altered the pads to do double-side reflow. As our own int
