Before attaching the heat sink sheet, clean up the contact
surface of the DMD module and Peltier Mounting with the
cleaning liquid. If there are some fragment of the old heat
sink sheet on the contact surfaces, warm up them with the
hair-dryer and then remove with plastic spatula.

surface. If there are some dust particles on the
surface, use the air spray to remove them.
