I recently added a mod chip to my JP Sega Saturn; having looked at some online pics and installation instructions, its been recommended to wrap the mod chip in materials such as cardboard/plastic/rubber/electrical tape to insulate it from shorting out the chip on the RF shield... a necessity for sure. I have no idea how hot these mod chips get, but like any electronic device - its going to produce heat and that heat will only become more intense if not allowed to dissipate. Heat is bad for electronics; will this wrapping procedure shorten the life of the chip... I don't know as I have not read of any examples.... maybe? So it got me to thinking about taking a different approach and I came up with using nylon ties to keep the chip in place and it will allow heat to dissipate from the chip, plus the installation looks neater. For a non-conducive pad; I used the rubber from an old mouse pad and trimmed it slightly larger than the mod chip. From the pic, you can see where I fed the nylon tie through. I tightened it just enough to keep the chip in place. Mod chip installation (V3 Universal) on a JP Sega Saturn model 2 (HST-3220), Sanyo drive model 610-6473-30.
