Sorry to see an old friend go away. A couple of weeks ago, Lou Reed passed away. Now this ...

Try to insert thin copper plate (approx. 1.5mm thk) at the end of the flow direction. Place it approx. 2mm away from the lead. The copper will pull away the solder & thus minimise bridging problem.

We use an ultrasonic stencil cleaner (not Smart Sonic) and have problems with stencils falling apart. The metal foil is pulling away from the screen. Is this a common problem with ultrasonic stencil cleaners?

Steven, Dave is right, wash them away. Since it is RMA paste, you may need to have a saponifier to go for Semi-aqueous washing. Or you may want to contact your supplier for a cleaner to wash it away with some agitation ( ultrasonic). Mag.

From personal experience with 4c's: run away as fast and as far away from them as you can. These will bring you nothing but grief.

Hello. We have a low profile LCC on a board. The clearance is ~ 2mils after reflow. Cleaning away residual flux with an ultrasonic 50C water cleaner caused some LCC and 0201 components to loosen. Should we stay away from the ultrasonic cleaner?

With the machine off, try to move all axes manually away from any limits, i.e.: away from the end of their course. Some machine can't deal with having axes at limit when you turn them on.

Patrick, It actually seems to go away after every adjustment. Whether it's flux, heat, doesn't matter but it always reappears. The part that has me baffled is the fact that another identical part is approx. 4 mm away, and never affects this one.

Can you give me any more information on how they take heat differently? Do they get hotter? Pull heat away from the PCB? Heat more even and pull heat away from the surface? Thanks, June
