So, you will need to solder the items to the board first before putting the PCB into a DDC pump? Then, solder 8 copper tiny lead-wires of the pump armature to the new PCB?

It sounds like a job for really tiny fingers and a professional hobbyist soldering station.

But the thrill to have an all out DDC with no limits and a POT (variable resistor) is very intriguing. I have several dozen DDC-1T (MCP350) pumps on hand but no pro solder station.
