dots of minimal height. So, use a lower viscosity adhesive. * Higher standoff components => larger (and taller) dots. So, use a high viscosity [typically, also high yield point] adhesive.

I am printing on DEKs and using simulara paramateres as for a solder it works really fine. In general going faster gives you more paste/glue. Less pressure gives you more paste/glue again. All the rest depends on your current board. Regards, Emil

Ok, thanks for the info, fortunatelly we already have our Camalot glue dispenser machine In-line with our MPM, for helping whit the high stand-off components.

Experts, Any advise on Hot Bar Soldering.I'm relatively new to this process.What are the pros and cons as opposed to using connector?

Yes I agree with Emil that the Jig/Fixture design is crucial for alignment. The hot-bar machine I worked with came with a digital camera and monitor to aid with alignment. Other than that, the right profile (heat, pressure and dwell), and a good fl

I wanted to hear from users of the SN100C alloy to find out what they think is positive and negative about this lead free alloy. Thanks, Keith

What I know for SN100 - it is designed for selective sodering. I beleave it is more expensive, compared to other alloys. Emil

Oh,I consider the process is wrong,it is stencil print paste-mount-reflow -apply glue-reflow,then wave solder. it must pass twice reflow,also the first reflow profile is different and the second .
