MTN Electronics designed direct-thermal-path 20mm Quad Copper MCPCB for Cree XP series and Nichia 219 series emitters. There is a solder paste stencil available here.
Each MCPCB includes (3) 1206 Jumpers to bridge the pads necessary for parallel LED configuration (no jumpers necessary for series). The LED's negative side (cathode) should be on the side with the "*" symbol. Two of the Pads have two symbols prefaced by *P (for parallel configuration) and *S (for series configuration).
2S2P configuration is also possible, but a bit more tricky. Please see 2S2P configuration picture for more information.
If you purchase a bare MCPCB, please remove the protective plastic coating before reflowing LEDs!
We will reflow any (4) in-stock bare XP-G2/G3, Nichia 219, or XP-L HI / XP-L2 LEDs onto this MCPCB.
If you purchase multiple bare LEDs, please indicate which you would like to be reflowed in your order checkout comments. Please also designate in what configuration you would like the LEDs to be reflowed (parallel or series---if we do not receive a checkout comment, we will assume parallel, since this is the most common designation).
Add Wires Service
For an additional fee, we will solder a pair of 22 AWG tinned copper silicone wires to your MCPCB (only if LEDs are being reflowed!).
