Are you absolutely sure the problem is with the humidity? We had a problem with 3528 size leds, damaged by the pick and place nozzle because a 0.2mm mistake in the height measurement. Also, we found that several suppliers are using fake desiccant ba

Need to pick between an inexpensive Manncorp manual axial lead former or the Manix unit. Any one have any experience with either of these two units?

First clean and de-bur the hole in the nozzle, then try it again. If the Head does not pick up at the feeder, then moves to the dump position...it means that the Vacuum Sensor Board has detected that the nozzle vacuum is above the LOW threshold setti

If you're still having this problem, talk to Al at MyData about replacing the ribbon cable that is wrapped inside the head, and connected to the two LED's. It's a bit of a pain to replace this cable, but, it did fix the problem for us. The other po

Yes, this is a good point and really only time will tell just how reliable such a machine becomes. What I'm aiming for is to simplify and reduce the number of sub-assemblies. For example we are building the camera/vision processor and lighting into

With what machine? I cannot help until that is disclosed.

Good question :) I'd say with a machine that is available for an average pick and place operator nowadays. Our manufacturer is not fixed yet, that's why I don't have any specific. On a related note I'm wondering whether the machine is so importan

Hi Folks, I'm working on a LED display that is composed of multiple layers. What is interesting for the point of this discussion is the PCB layer and the light deflector layer on top of it. Please take a look at the related pictures at http://plus

I would expect any half decent machine to place 0603 parts slap bang on target to the typical defined accuracy for such parts on most machines of perhaps ~60 microns or better. Self correction during reflow is IMHO much less pronounced with lead-free

Flexibility (if what I am thinking about flexibility is correct) is more important than speed. Most of the time spent on reloads, not the runs. We have high mix and fairly low volume (100-1000) Medium complexity QFPs, 0402, LEDs 100-2000 components p
