I have been ripping the Ali heatsinks out of TV's for a while.
I have to unscrew the screw that holds the transistors on & rip the little metal tags that they use to solder the heatsink onto the circuit board off. I used a needlenose plier.
Theres metal pins of 3 designs (whole pin - 2peice pin & hollow pins)
The hollow pins break if you don't get it right the first time.
I found out quickly that its best to bend the heatsink 'off & out' around the hollow metal pin.
That makes it loose enough so that the pin will pull out 'first go'. You can't have ANY of the metal pin left on the Ali heatsink.
I'm left with -
The metal soldered tags (steel clip)
Nuts, bolts, screws & washers -(all steel),
Transistors (Copper)
The actual Heatsink (Ali)
So to quantify it I counted them &...
66 various Ali heatsinks weighs 2Kg, thats NZ$2.40 worth.
Not much but I will keep doing it, the Fe & Cu helps.
Or about US$2.00 for 66 heatsinks.
All from TV's, any sizes. Thumbnail to envelope size.
