Each thermal cycle decreases the thickness of the OSP. So depending on the material, fabrication method, and blablabla; after one thermal cycle we'd expect the OSP to provide adequate protection for a couple of days. After that, you may need a more a

Hi, This week I received a newsletter from the people from High-Tech Conversions, offering an under stencil wipe which needs only water to activate its and clean. My question is, did any body tried it? Is it better than cleaning with solvent?

Low tombstone pastes have been around for 8-10 years. Talk to your paste supplier about suggestions of the "latest and greatest." Usually these pastes: * Are a blend of alloys with slightly different melting points * Have a mid-level activity flux *

Manually load the board and activate the solenoid for table up/down. Goto I/O then check the status of the sensor. if the sensor was tripped when table is down, removed the pin and check for foreign objects. Or check the hole of the pcb, maybe the si

Glycols, polyglycols, polyglycol surfactants, polyethers, and glycerine are used in water-soluble flux formulations because they provide excellent wetting of the board surface and dissolve the more active materials used in these formulations. [Printe

Keep in mind you'll still need to preheat the assembly to properly activate the flux/drive off volatiles in the paste. Perhaps a convection toaster oven... Add some cooling coils and a freeboard/tube to the top of your pasta cooker or turkey fryer t

We currently use and have used Aim W/S 483 for the past ten years. We have had great support from AIM. Paste Characteristics, wetting, slump, washing is all outstanding. Great activity, works well with NiPd and other lead frames.

Check your reflow profile as well, it could be that your ramp rate from flux activation to reflow might be too steep. This is in the same line as the post from Ken. Too fast a rise in temperature will collapse the outside rows too far in advance of
