Soldering 1N4148 so close to the glass body, plus using a thick drop of solder, makes it really easy to overheat the diode. They are everywhere because they are cheap, not because they are robust... The diodes may become unconditionally conductive, so it may not be an obvious bug. I fried many of them, because my soldering skills were not that good, I did not read the data sheet and so my iron was too hot and I soldered them for too long. Plus by using short wires, all the heat transferred into that fragile glass body. |
