Assuming that's all that wrong with it!Hey Dirk,
I have two boards on my bench, #1 and #2... #1 has the small aluminum heat-sink and a burned out LED driver (failed from overheating). #2 has the thick copper heat-sink and would be fine except the installer ripped J4 off during installation.
The LEDs on #2 are fine and the traces failed from the mechanical stress of attaching/removing a quick connect to it (I don't think heat will affect the traces on the copper boards). I figured #2 would work if I could fudge the J4 connection, so that's what I did in the photos above.
I still plan to repair #1 and then take temperature readings on both, but I won't do that until I get a hot air rework station (coming soon) to do the LED driver removal/replacement.
Incidentally, I saw a board with a torn off J4 on eBay for 40 bucks... if my fix would fit in the housing, an enterprising person could have themselves a cheap replacement!
That is simply poor design.Since the J1 and J4 connectors are surface mount, they're depending on the adhesion of the trace to the board substrate (a copper or aluminum plate) to handle the stress of connection/removal.
You could opt for something simple like some copper plate etc - that would probably enough to take the edge off the heat being generated within the driver.I wouldn't use a "stick-on" or adhesive heat sink because it will likely fall off...
