Matrix supplies phase change thermal interface materials for electronics applications. At a clamped joint between a heat-generating component and a heat sink, these materials offer a dry pad format during assembly and a changing contact behavior as the interface warms. Our phase change material offering supports that connection between material and application.
A pad that changes at the interface
Parker Chomerics THERMFLOW materials are solid at room temperature and soften at their specified phase-change conditions. This allows the material to conform at the contact between the component and cooling surface. The behavior belongs to the selected product and the thermal conditions at that joint.
This is a different format from a thick gap filler spanning a larger separation. At a clamped heat sink interface, the material occupies the contact area between closely mating surfaces. The footprint, attachment arrangement and intended operating cycle influence which construction is appropriate.
The supplied shape belongs to the component
A phase change pad can be supplied in a shape that follows the intended contact area. Matrix supports precision converting for suitable engineered materials, including review of shapes and sizes around the component footprint. That connects the selected thermal material with a part used in the electronics build.
A defined pad format can also make the interface material a recognizable item within the assembly. The material designation and supplied outline remain linked, so a heat sink requirement can be discussed in terms of the actual contact location. Matrix can assist with material selection and sample inquiries for that evaluation.
Thermal material support from Matrix
We distribute and convert appropriate third-party materials. Parker Chomerics supplies the THERMFLOW formulations and their technical documentation; Matrix supports the application discussion and suitable supplied formats. Product choice includes the joint conditions and any electrical insulation requirement, as thermal interface materials do not all provide the same dielectric function.
Contact Matrix to discuss a phase change thermal pad for your clamped heat sink interface, including candidate materials and the contact shape required by the equipment.
