ProtoDAC TDA1387 X8 project

I have personally not experienced a module failure. I only use and sell modules that test with the highest voltage output. The modules are made with recycled chips, so they may be prone to failure. To date, with the hundreds of kits I have sold, no one has reported a module failure.

I think damage to the chips due to soldering the module pins would be difficult, because the trace length from module pin to chip lead is relatively long.

I recommend soldering only the 7 required pins (1, 2, 3, 5, 6, 25, 28) to make any module exchange easier. I would recommend removing a bad module by cutting the pins, and then desoldering each pin individually.
