| + | This gallery shows some pictures of bad solderings - they should prevent you from making the same errors (feel free to add even more pictures here!) | ||
| + | |||
| + | 1: the core module has some bad solderings (loose connections), which could lead to failures. There are also missing solderings (e.g. 33pF cap below crystal). It makes sense to solder each pad again, the [[Soldering]] guide in the Wiki gives some useful tips\\ | ||
| + | 2: the legs of the caps should be cutted, otherwise they can cause a short circuit which can damage the PIC!\\ | ||

| + | |||
| + | 3: this seems to be a bad ground connection directly at the 78xx - it can lead to the wrong voltage. Here the same: just solder the pads again, it will help\\ | ||
| + | And same like above: the long cap legs need to be cutted, the danger for shorts is too high!\\ | ||
