I just finished wiring up 2 BB750s ready for installation into the McModule. The BB750's were tested fine. Both lit up my 5 watters when they were powered from my 6V battery holder. I then fitted a BB750 into a McModule, powered it up for a few seconds to make sure contacts were not lost or loosened during the fitting. No problems there. The next step was to pot the circuit in the McModule with Artic Alumina to aid the transfer of heat from the components to the McModule.
Note the added copper heatsinking on the LTNH and the diode /ubbthreads/images/graemlins/grin.gif
After potting and letting it cure for 30 minutes, I proceded to test it inside a PM6 host running 2 x 123s. What I found was frustrating! After about 10-12secs on, the light dropped from max brightness to moon-mode. By moon-mode, I mean I can look directly at the 4 dice in the 5 watter lit.
I also tested the BB750 which I haven't installed into the McModule and it does the same thing. That is, it would go to 'moon-mode' after about 10-12 seconds of power on. So what's going on?
