All, I recently purchased a microscope camera and have been trying it out on various items. Have placed two photos on the IPC website which I believe illustrate a tin [or solder plated] lead on which the plating has reflowed and squirted out from beneath the mold compound. Have seen similar manifestations with improperly processed solder & glob-topped assemblies. http://ipc-technet.groupsite.com/gallery/22093 filed alphabetically under folder name - Tin Plated Leads Anyone else have other ideas? Please keep in mind that this an old modem board of unknown chronological vintage that I had in my 'scrap bin'. It just happened to be the subject of my scrutiny. I see no evidence of solder balls, etc on the board.
