| | | | | Hi, | | | | | | | | | | I need some urgent informations on stencil design guidelines on how to perform epoxy printing on 0603 and 0402 components. Could anyone help? ( Reflow process is not possible because of some other constriants) | |

Russ, On both instruments, I ran them through the wave 20 times each using identical profiles and wave parameters, and then used statistical formulas to measure the variation and repeatability of each. I had these all in Excel, but that was around 1

SuMoTe, that is a fair suggestion, but I believe will be a non-starter. The solder pump motors are actually 40V motors being run from a PWM 24V supply. I did one time try hooking up to a separate power supply up to 40V but all this seemed to do was m

Thanks Bukas. I've actually gone to a lot of trouble over the past 24 months to completely clean, rebuild and adjust the pump and nozzle assemblies and even through all of that we've still never been able to get theoretical maximal wave height from t

Here's what I do: - Test Surface Insulation Resistance (we're in the high reliability market and use a test significantly harder than IPC's). I also test SIR in combination with other assembly materials like conformal coatings and wave solder flux

are you using composite pallets in the wave or oil/wax around the pump impellar? cheers greg

This may not be a solution to your problem, but something from my tuner car days jumped into my head. If you are running at 100% and not getting the height you need, change out one (or both) of your pulleys. A bigger pulley at the motor side, or a sm

Check the temp of your pot. It may be getting cooler if you can notice a difference in pump height and density. You may have lost a heater element or two. You can adjust your pot chemestry, but why would you want to if your solder sample came back

i had 2 pumps xD also, propeller size can give you a clue. do some research on turbines of any kind, its same principal. you can have someone check it for you on same machine, i'm sure someone will help.
