A regular XM pattern MCPCB won’t work cause the center thermal pad of the LZ1 is larger than an XM thermal pad and contacts the XM + & - pad’s in the center. Not a problem with the xml color pad cause the + and - pads are divided into 4 tony sections isolated from eachother.

Ask VOB he my have one or two more xml color sinkPAD’s left, tho if you only drive it at one amp you don’t really even need it (tho DTP never hurts).

FYI at 1.4A there is no need to run a reduced duty cycle when on a DTP board, that’s what DTP boards are for.

Since the color SinkPADs aren’t available, having a DTP solution has been bugging me. Since the LZ1 thermal slug extends into the cathode and anode pads, your solution was to cut the traces of the center two pads of the cathode and anode of the color SinkPAD.

Then I stumbled upon this thread where djozz made a XML Color board from a 16mm round XML SinkPAD. He cut through the traces with a scalpel, checked for continuity and filled the cuts in with Arctic Alumina to keep the solder out of where it shouldn’t go.

Then I had a brainfart after seeing how the traces of the 16mm round look and came up with a idea on mounting a LZ1 on a 16mm round SinkPad. I’d prefer to use a the 20mm star so I could use a host like a Convoy M1 or M2 but I can’t find any high res shots of the 20mm SinkPAD to see how the traces look on that model.

What do you think? Will my brainfart work or did I just end up having diarrhea of the brain?
