| OK, I have finally got one of these puppies to work. The "H" doesn't mean a thing. linears4 was correct. Thanks to him I kept trying and finally succeeded.
By the way, I think my issue for these not working was uneven heat distribution from the upper heater. I am using the reflectors, but be very cautious. You have to test where the center is or the heat will not be even all around the chip. DON'T RELY ON THE LASER. It is just as important to check for laser accuracy as it is TC accuracy. The reflectors are not centered automatically, you need to adjust them. I now use 2 TC's every time. One on each side of the chip to insure even heat. This has proven to work for me. |
