Heat Sink Note

These heat sinks are a very unigue & easy way to dissipate the heat generated by 14 to 16 pin ICs such as those on the Pac-Man boards at positions 2A through 2D. If your ICs are good & only missing the heat sinks you'll need to glue these on as the OEM chips were sitting flat against the PCB when soldered in. You can glue the spring clip to the top of the IC or you can cut off the spring clip portion & glue only the fin portion of the heat sink to the IC. I use to use GC's Radio Service Cement, but I've been told that was discontinued. I'm sure there must be some equivalent on the market today... or perhaps something better for this purpose. Some of you have reported a few odd ways that have worked, such as TC who says that fingernail polish works great :-)

If you are replacing the IC that requires a heat sink then these are made to order easy for you & require no glue at all. They simply clip on the chip and in doing so, use both the top & bottom of the chip as surface contact points, funneling the heat to the fins for dissipation. You can clip them on prior to installing the IC or just be sure to leave the IC up off from the PCB enough to clip them on after soldering... although clipping them on prior to soldering may be beneficial in keeping the chip cool during the installation period!

These black annodized aluminum heat sinks really do a great job of keeping the chips cool & are much better then the OEM in MHO. They sell for a buck a piece at most electronic parts stores, but I was able to find a batch of them at half that when my supply of them ran out & y'all kept asking for them. Hopefully, I've got enough to last a good while now, so they can continue to be on the Dollar Store Page at two for a dollar.
