I'm interested in adding a heat spreader to a group of components on a PCB. The components are very fragile so I can't apply pressure to them, even a soft silpad would be too much. My plan is to use a liquid gap filler underneath a heat spreader, but I can't find any vendors that sell them. I'm referring to the sort of lid that is used on CPUs, which mount directly to the PCB with adhesive and have a cavity to accommodate the CPU die. Like in this picture:
Any ideas? I need about 1-2mm of clearance, and it has to cover an area of at least 10x10mm.
