Mounting with Phase Change Thermal Interface Material

A phase change thermal interface material (PC-TIM) between the resistor and the heatsink is required to mount the resistor and enable the full use of its continuous power and thermal monitoring capabilities. Vishay offers the option to deliver the resistor with the PC-TIM pre-applied to help streamline and simplify the customer’s procurement and production processes. To mount the resistor with the optional PC-TIM, make sure the heatsink is clean and the PC-TIM has not been compromised. Bring the bottom side of the ISOA resistor to a minimum temperature of 60°C for 60 seconds either by applying power or by applying heat directly. For disassembly, bring the PC-TIM to a temperature of 50­°C before removing the resistor. Resistors with the pre-applied PC-TIM should be stored horizontally, in a dry place, and contact with other surfaces should be avoided to prevent compromising the surface of the PC-TIM. It is also recommended that the PC-TIM be used within 3 months of the date code shown on the resistor. If the PC-TIM is damaged during assembly or disassembly, it is recommended that the resistor be discarded.
