Purely from a technical interchange perspective, how thick is a slice? That is, what is the Z axis resolution of the machine? This isn't listed on the web link. There are pictures that imply separate of a BGA on the top and discretes on the bottom

When you measure "solder paste heigth of 7 & 8 mils using a 5.0 mils stencil," are you measuring the top of a flat brick? Sometimes if you snap-off the stencil too fast, the paste touching the stencil walls form peaks along the edge of the brick that

Bob has been very helpful so far. He was very reasonable on the price for the manual too. I think I'll have this thing in production by Monday Morning! So far I've replaced the 5V Power Supply, re-aligned the X and Y, and re-laminated the table to

What is the purpose of glueing it? If it is glue the bottom side parts followed by reflowing the top side parts followed by wave soldering the bottom side parts, then it's easy to measure. Hold the board with the 0603s facing down. If they don't f

We have A heller 1809 2005 model have replaced the chain drive motor twice have replaced 2 top blowers and one bottom blower as far as reflowing the solder performance has been great. the tech support has been great as well. we run 3 shifts 5 days

It would, but is it correct? This is what QA came back with. "Think of a chassis, connected to earth ground, sitting on top of a mat. In this situation, we are bypassing the meg-ohm resistor to ground." If the mat, the operator and the test equipmen

Well, since you've gotten no takers, we'll launch in to this with careful analysis and introspection, fully aware that we're likely to get 'blasted' for any number of reasons. The most critical parameters to monitor for proper wave solder machine pr

Hello Everyone, I have noticed that everytime that we have ran a PCB with fine pitch components (or even 0603s), there are little white strands on the leads or on top of the components. It occurs on both lead and lead free solder. We usually soak

This is not a common method of defluxing. Vapor degreasers were the top choice pre-1989 but have given way to spray-in-air defluxing technology. Here come of the vapor degreaser manufacturers: Detrex http://www.detrex.com/ Baron Blakeslee http://
