EEEk!!! Soldering is a skill... don't let him anywhere near it. Inspecting solder joints is not easy, especially for novices.
I predict cooked board, delaminated tracks, overheated components....

Best would be to clean the print with IPA, as arne suggests. Then take a magnifier glass and inspect the solderings carefullyand resolder bad ones. Then again clean with IPA. eric ------------------------------------------------------------------------------ From: neonixie-l@googlegroups.com [mailto:neonixie-l@googlegroups.com] On Behalf Of Dman777 Sent: zaterdag 11 oktober 2014 3:38 To: neonixie-l@googlegroups.com Subject: [neonixie-l] Re: Nixie Clock Cool Project- a few questions I was studying the area where the heat is trying to figure out where the heat is coming from, since there are no real components near the heat concentration. Using my camera and zooming in, I see some strange markings on PCB board surface and some brown/burn spots also. Could this have anything to do with the heat concentration? What are these from? I attached a couple of pictures. Thanks, -Darin ...clip.... -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
