There are many factors that will affect post soldering height. Lead shape/type, pad geometry, fillet formation, etc... You will need to measure each type of component before and after reflow. Russ

Does anybody know of any document(s) that define the different package types such as SOP, SOIC, VSOP, TSOP,TSSOP, QSOP, LQFP, VQFP, etc...? I am re-doing our component library and would like to use industry names for each component type. Thanks Rus

I just had a better idea, why not make your own template. A cylindrical guage printed out on a piece of mylar. A series of concentric rings with a quantity on each ring. Use it as an overlay.

Could you provide the specific alloy info (percentage od each) OR provide the melting point of this alloy? Please also provide the component specs (pitch, ball diam.) And the pad size and design used on the board. Russ

You need to know flows, pressures and costs of bulk. Plus purity requirments. Each use is different.Savings can be big. Email me if I can help, I sell these units

Please ignore the v-score figure it did not come out the way I intended. The v-score is not uniform in that equal amounts of material are not removed from each side of the board.

We have considered running a spare board with each job as a possible solution, however due to the cost of the assembly, this would not be preferred.
