ABL HEATSINKS 345AB1000B HEAT SINK

another application is the attachment of delicate electronics to heat sinks here we're comparing the commonly used thermal grease to our metallic glue in this case we have a CPU attached with a heat spreader to the heat sink using thermal grease the grease here gets pumped out over time due to thermal cycling and can cause gaps in this interface causing poor eat transfer simulating a direct die attachment to the heatsink without the heat spreader here we can see that grease getting pumped out after this has been thermal cycle this is the metallic blue attachment it's a permanent attachment and so it doesn't it doesn't experience any that pumping out here we can see it's a very thin solid seal to the heatsink directly from the silicon wafer
