Hi all, Recently the place where I work at purchased an SMT assembly line. The stencil printer is a used DEK Horizon 03i. We received no manuals with it and are having issues with the cleaner. The motor does not move and it does not move along the ra

Honda, Prnting Glueisn't as difficult as it sounds, as long as you have the right stuff and a good set up. It also depend's on what your going to be placing. If your just doing 0603, 0805 and 1208 than you really only need an 8 thou or 10 thou stenc

Hi Antonio: You clearly have printed excessive amount of solder paste on the pad. You can reduce the amount of paste by one or two methods: 1. Switchover to 5 mil thick stencils. 2. Change the design of your stencil openings (at the discrete compone

Paddesign, aperture size and stencil thickness determine the amount of solder for your joint. Once you have found suitable parameters you need to control the volume of your paste deposit which is influenced by printer settings, paste condition, stenc

1. Throughput * Dispenser: Slower, may loose 70% of tact on fast chip shooters * Printer: Can be put in front of and use fast chip shooters effectively 2. Rework Rate ???? Deposition control???? * Dispenser - High control over amount paste - Coplan

I presume you have no vision alignment. Buy yourself a little monocular measuring microscope ( about $100 ). You are not going to get the registration you require between stencil and pcb for each print if you are running off tooling pins , edge clamp

James, we used to use 3 clamshell type printers (one of which did have a two camera vision system, and did all our fine pitch), but had limited success with 20 mil pitch. 25 mil pitch was no problem. I suspect that you'll find people that have had

Hi Todd, it might be a philosophical question if soldermask between finepitch pads is prefered or not. That should depend on the capabilities of a particular site and their experience. We actually prefer soldermask down to 0,4mm pitch and don�t have
