Gap pad/Putty pad identification and location
Follow the information in this section to identify their shape, location, and orientation of the various gap pads and putty pads used in SD650 V3.
Installation Guidelines for gap pad and putty pad
There are two types of thermal pads: putty pad and gap pad. When replacing components, always replace putty pad. Replace gap pad if it is damaged or missing.
Attention
The putty pad is unfit for use if the expiry date on its packaging has passed. Acquire a new putty pad for proper putty pad replacement procedure.
