New 3030 DTP boards in 16mm and 20mm size, made specially for Osram white flat LEDs, but Osram has some other high power LEDs in that size too.
Reason for these boards over XP/3535 boards is that with XP boards white flat LED like to slide on one corner during reflow causing off-centered LED if it's not re-centered during reflow with tweezers.
For small qty this may be ok, but for me it was a PITA. With new 3030 boards there is no such problem since footprint is exact like it should be and LED is always nicely centered.
These PCBs have factory lapped bottom surface and they are fully gold plated, so price is little bit higher than nickel plated PCBs. Also PCBs in panel are separated by double V-cut for nicer and cleaner cut without notches, this also adds ~10-15% cost.
From now on I will only have white flat LEDs soldered on 3030 PCBs, I already changed listing for 20mm white flat 1 and 2, and will do the same for 16mm after few last pcs soldered on XP16 PCBs are sold.
Man how I wish you got the FA1, FA4, FD1, or FD4 tint bin. I would have bought a bunch presoldered on your mighty mcpcbs for sure. Too bad the FC1 tint is above the BBL and I can’t get used to any emitter with greenish tints.
Okay guys, I just installed an LD-B4 and a MOSX with Luxeon MZ in a C8…
It lights ON but I don’t understand how to switch modes, or config or whatever.
With the closed website I can’t access to the datasheet sooo… anyone knows how these work please ?
