HELLO, Do anybody know if is existing an empirical rule that can show me how many amps can carry a plated through hole with a diameter of x.xx millimeters? Is there a formula depending on X.XX value that could help me to make such calculations? How

I would like to perform a Solder paste height capability study. I will apreciate any info about and what equipment use to measure the height of the solder paste. I only found the attached equipment. Solder Paste Height Measurement System (SPM-300-3D

1500 lbs) vary by a couple of degrees) were standard. I thought that flux penetration into PTH barrel and solder pot immersion depth and solder pot parallelism would be also critical factors. We are using the ECD WaveRider to measure the implied sold

Wave set-up DOE * Immersion depth [1/3 to 2/3 of board thickness] has the least impact of any variable in wave soldering. * Contact length the greatest impact. * Control flux density, time through preheaters, top side temperature as the board reaches

The variables to study: * Dwell Time * Contact Length * Conveyor Speed * Parallelism * Top-side Substrate Temperature Before wave * Solder Pot temperature All of these variables are inter-related (ie changing one variable will affect another)

Is this topic on Wikipedia, Facebook, or MySpace as well?

Im not sure if someone has posted this topic before. Anyway,we plan to make capability study on our wave-soldering machine but we have no experience on how to do it effectively. My question is what we should consider most among the critical parameter
