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-N 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 detached.
Attention
Do not use expired putty pad. Check the expiry date on putty pad package. If the putty pads are expired, acquire new ones to properly replace them.
See the following for gap pads, putty pads, and PCMs used in SD650-N V3:
