Whether or not SnPbAg will cause issues is trivial. You must build to the solder specified on the print.

What do you mean by "airborne"? We have been using SnPbAg for 15+ years to build assemblies to IPC class II standards although with most assemblies going to Pb free, we are not using it near as much as we used to.

One of the things you need to know are the parts you are building Flight Critical. Meaning if the board fails will it bring down the aircraft. Or non critical meaning one of the over head light will fail as an example this determines how much latitud

Sir I more information i did not shared with you. The finish of this critical board is ENIG. Do you recommend ENIG finish for the flight critical boards

paste should be 12-16mm in diameter. If your squeegee is the same size as your roll you shouldn't observe any difference for 15boards. Adding paste is important when you run hundreds and thousands of PSBs.

Does IPC definition for "QFN Void Ration" ? Like IPC 7095 susgestion the BGA Void ratio.

there is no clear percentage for the total voiding, but I know that single voiding shouldn't cover two via holes(defect)

Would like to know if some exists norm that refers the parameters for test of extraction (pull test) of components SMD using adhesive.

We are having a problem setting up the Mirae MR20LP Pick and Place Machine.For some reason the program cannot see the feeders.All the feeders in the program are in Yellow which means FEEDER MISSED but supposed to be green.
