PiStorm32-lite: JLCPCB soldering issues
Since about three weeks the building instructions and documentation for the PiStorm32-lite are available (amiga-news.de reported). After that, many interested people ordered the necessary parts from JLCPCB. Some problems occurred during assembly, which Andrew 'LinuxJedi' Hutchings now summarises in his latest blog entry:
Apparently, the holes in the bottom of the boards were filled with metal balls. This was especially the case with orders placed via JLCPCB's economy service. Basically, the problem could be fixed by poking the balls out from above with a pin.
It was quickly found out that the problem was excess solder paste that got into the holes during the Reflow process. In a few cases, however, even the solder penetrated the metal of the plug. The developer goes into detail about the exact reasons for this in the further course of his explanations. (dr)
