1. 2. FM-PCB mounting
Heat dissipation compound :
Shin-Etsu Silicone [ G-776 ] grade  0.05g
Apply heat dissipation compound
DMD heatsink type
DMD radiator pump type
2) Clean up on the rear of the DMD chip
 t  Remove the old heat dissipantion compound on the rear 
surface of the DMD chip cleanly.
1. Preparation
1) DMD heatsink or DMD radiator pump preparation
 t  Remove the old heat dissipantion punpound on the rear 
surface of DMD heatsink or DMD radiator pump and apply 
new one evenly.
 t Take care that compound does not stick out.
Interposer
Remove the 
remaining com-
pound cleanly.
Caution!
Do not touch the part of the metal pin on the interposer and the 
contact part on the FM-PCB. Cause the poor contact outbreak
