ZFW TIM Tester gen2 Thermal Interface Material Tester

ZFW TIM Tester gen2 Thermal Interface Material TesterisZFWA thermal interface material testing instrument developed for studying thermal conductivity and insulation materials, such as gap fillers or gaskets, adhesives, and foils. In addition, both the substrate and the solid can undergo thermal analysis. The development of this device began with2012Since then, it has been continuously developing and improving. Meets ASTM D5470-17, IPC-TM-650 2.4.54 testing standards

TIMThe tester has now received good market feedback. This testing device is used by many well-known companies, especially for testing gap thermal conductive materials.

The test bench can accurately measure the (effective) thermal resistance of the sampleRthDue to the high-precision resolution of gap measurement (measuring layer or sample thickness), the thermal conductivity of materials can be accurately determinedλ.

By measuring different layer thicknesses, the contact thermal resistance between the thermal conductive material and the aluminum test surface of the equipment can be determined. Generally speaking,TIMThere are several measurement modes in the tester, depending on the type of material being tested: for low viscosity samples, thermal resistance orλeffThe thermal conductivity as a function of gap (layer thickness) can be measured without pressure, while for solid materials, thermal resistance is determined as a function of contact pressure.

ZFW TIM Tester gen2 Thermal Interface Material Testeraccording toASTM D5470The fixed cylinder method is usually used for measurement, which has been established as the standard testing method for the heat transfer performance of thermal and electrical insulation materials

ZFW TIM Tester gen2 Thermal Interface Material TesterIntended to provide comprehensive thermal characteristic analysis of materials, its functionality goes beyond basic testing and can achieve:

· thermal resistanceHigh precision measurement of the heat resistance of the sample.

· thermal conductivityBy using high-precision gap measurement technology, calculate the true thermal conductivity of the material.

· contact thermal resistanceBy testing different thickness layers, the device can separate the contact thermal resistance between the material and the test surface.

· Optical gap measurementThe high-precision non-contact optical method is used to measure the interface gap, which accurately reflects the gap changes caused by compression and thermal expansion, improves the accuracy of thermal resistance and thermal conductivity measurement, and reduces the uncertainty caused by parasitic thermal paths.

· Complies with international standardsAll measurements strictly follow the steady-state heat flux meter method and comply withASTM D5470andIPC-TM-650The standard also provides multiple measurement modes in addition to these standards.

Multi functional measurement mode

To adapt to materials of different viscosities and morphologies,ZFWThe thermal interface material tester provides two distinct control modes:

· Gap control modeSuitable for low viscosity materials such as thermal conductive silicone grease and paste, it can measure the functional relationship of thermal performance with specific layer thickness.

· Pressure control modeSpecially designed for high-performance thermal conductive silicone grease, films, solids, gaskets, and elastic materials, capable of withstanding temperatures up to2 N/mm²Measure thermal resistance under specific contact pressure.

ZFW TIM Tester gen2 Thermal Interface Material TesterOne of its functions is its ability to perform compression and expansion tests. These tests can be conducted using quasi-static, dynamic, or cyclic methods. this kind of“Layered testing”The thermal expansion phenomenon of the heat source and radiator during actual operation was simulated from a mechanical perspective.

· Predicting thermal failureContinuously record changes in thermal and mechanical properties (gap and force) over multiple cycles.

· Determine the adhesion limitAccurately indicate the force or gap value at which the material separates from the interface, thereby effectively preventing thermal failure caused by delamination or peeling.
