can anyone tell me what the white stuff is on a VCO chip?

can anyone tell me what the white stuff is on a VCO chip?

2008-01-30 by rj krohn

hi guys, i had to temporarily remove a few VCO chips. this obviously required me to "break the seal" of the diode, or tiny resistor, that is adhered to the face of the VCO chips with some white material.

those voices are now just a little less stable than the others. im assuming that heat regulation between those two parts helped stability-what should i use to "re-adhere" that part to the face of the VCO chip?

thanks alot!!!

Use new dielectric (!!) thermal compound kit. I removed the old kit
some months ago and applied new kit on all oscillators and it
improved stability a lot. I used coolermaster high performance kit
from a electonics webshop.
