The ONLY (unlikely) cause I could think of is if you are pushing the component into the solder, ending up with more solder on one side than the other. Why do you think it is the volume of solder that is causing this? By the way, there are "low tomb

On SMTnet, we've discussed the the frailties of controlling paste height, when volume is a more telling measure. Sometimes if you seperate too quickly, the paste tries to stay attached to the aperture walls. This creates a 'U' shaped deposit with r

We've actually bought a second FX-D, which is intended to mainly handle smaller, higher-volume boards. That will still serve to improve throughput. But at the same time, we're also adding another pick'n'place machine which has a rated speed that's 2

Here's what I do: - Test Surface Insulation Resistance (we're in the high reliability market and use a test significantly harder than IPC's). I also test SIR in combination with other assembly materials like conformal coatings and wave solder flux

First, what would you define as semi-automatic? For SMT production you might need a screen printer (these can be anything from full manual to full auto. The low end printers manual require each board to be aligned with a piece of mylar prior to p

Thanks for your advice. My business model is fine, but I just find it to be unreasonable that there isn't a "no frills" oven below $3500 that maintains quality. I'll spend that much if I have to as I don't want to mess around with bad solder joints o

There are a few directions to go from Here... 1) Outsource it to a CM, 2) Capital investment both have there issues. To Out source I would have processes in place to Inspect quality, resolve issues, Assure quaility, and Hope they can meet your deadli

I just got a used Philips CSM84 pick and place machine for $1500. I had to widen a doorway and rent a forklift to get it inside, as well as have it shipped. So, the total cost was much higher, but still under $10 K. I may have gotten lucky on this

Doesn't exist. True Solder Paste dispensing is a Mycronic only solution with Essemtec coming behind with slightly less cpapbility. With Essemtec you can have one machine that prints and places, that saves space, with Panansonic you can have machines
