How is the thermal resistance of an IC package determined?
The thermal resistance of an IC package is the measure of the package’s ability to transfer heat generated by the IC (die) to the circuit board or the ambient. Given the temperatures at two points, the amount of heat flow from one point to the other is completely determined by the thermal resistance.
When to use a tester for IC testing?
Test Philosophy The tester is used to test an IC for any opens and/or shorts on any IC connection (pin/BGA). The test of the IC is intended to insure that all common pins are connected to the same network of pins, independent pins make a connection to the die, and there are no shorted pins.
How is the junction temperature of an IC determined?
Given the temperatures at two points, the amount of heat flow from one point to the other is completely determined by the thermal resistance. By knowing the thermal resistance of a package, one can calculate the IC’s junction temperature for a given power dissipation and its reference temperature.
How does the enable pin change with temperature?
The input resistance on the enable pin increases linearly with rise in temperature. So, with a constant voltage applied on the enable pin, the enable input current should decrease linearly with rise in temperature.
Why is it important to consider thermal management of ICS?
Thermal management should be considered during package selection to ensure high product reliability. All ICs generate heat when power is applied to them. Therefore, to maintain the device’s junction temperature below the maximum allowed, effective heat flow from the IC through the package to the ambient is essential.
How long does IC diamond thermal compound last?
IC Diamond is truly an outstanding thermal product with the combined attributes of ultra-high performance and high durability. IC Diamond lasts 3X-4X longer than your typical retail compound.
What is the thermal conductivity of IC Diamond?
IC Diamond ® Thermal Compound. Purified synthetic diamond has a thermal conductivity of 2,000-2,500 W/mK compared to 406-429 W/mK for pure silver. Diamond’s five times better thermal conductivity compared to silver makes it a superior heat transfer material for cooling high performance CPUs and is electrically non-conductive and non-capacitive.
