Dreamy It sounds like you are having fun in your new job. Saponifier. Alkaline chemicals, added to water, that convert rosin/resin flux residues in the water to soluble soaps. Generally, saponifiers are better if used in an aggressive spray-in-ai

Hi Grant, If you're really looking for speed, I'm sure you're looking for another machine for doing the QFPs, BGAs stuff etc. In that even, why not have a look at the long proven Assembleon FCM machine!! It is a totally different concept with UNMATC

I am an equip mfrs rep. I took a customer to my wave solder principal's factory to run their boards on a wave with no-Pb alloy, (Sn96.5 Ag3.0 Cu0.5) in air environment. The results were excellent with pot temp of 263C (505F). Their boards are low to

Shameless? In APE's experience not so - air velocity/power is extremely important in carrying energy to the board and close loop control of that energy is crytical in maintaining a controlled environment - if a machine design requires that air is for

I've worked with a Vapor Phase Oven a semi-automatic and a manual oven for evaluation. They worked fine and produce better grain of solder joints. The fluid that you need depends on the solder temperature that you require. I've used a 200'C fluid for

Hi, I think you cannot go wrong with Convection. If you want to experiment with VP, just get some of the fluid and put it into a pasta cooker on a standard domestic hot plate. Have a basin full of cold water so after reflow you can lift the cooker a

65%), if one failed on the board i replaced all of them, and re-tested and thermally cycled them inline with our spec (-55/+80 Deg/C for 48hrs) this was a nightmare, especially when some cracks were not detected until several weeks later while flying

Stefen- When looking at it from your perspective only it makes no sense to off-shore. The machines and operators are but a small part that goes into the decision to move overseas. The bigger picture is the fact the "entire" operation gets outsourced.

Well...here is what I can tell you: I have over $40K worth of bent A12,A13,A14 tools.Yes you heard me right $40K worth. (Since 1995) Mydata used to make a repair kit to fix them but decided to quit. They tell me the reason they quit making the kit i
