Gap Filler: Thermally conductive, liquid gap filling Materials

Gap Filler is supplied as a two-component, room or elevated temperature curing system, resulting in a soft, thermally conductive, form-in-place elastomer ideal for coupling “hot” electronic components on PC boards with an adjacent metal case or heat sink. Gap Filler is primarily for use in applications where a strong structural bond is not required.

Supply Chain Simplification

Liquid, form-in-place Gap Fillers are adaptable to multiple applications, allowing single part sourcing for a variety of different jobs. Instead of ordering large quantities pads or films – where each variety of size and thickness is a different part number – a single Gap Filler product can satisfy thermal control requirements for several products. Simply dispense where needed, the material forms in place and thermal control is achieved. One product, many applications.

Low Component Stress

As compared to thermal pads, liquid thermal interface materials lower overall component stress Even though pads are soft, the compression applied to the pads once they are placed puts stress on components. Gap Fillers, on the other hand, require significantly less force to wet out the liquid. These unique materials flow into all of the voids of even the most delicate circuitry and then cure in place to form a solid pad-like structure, which also safeguards against shock, vibration, drop, expansion and mechanical stress.

Automation-enabled High Throughput

When speed, high throughput and exceptional thermal control are the challenges, Gap Fillers are the solution. Applied via automated dispensing systems, Gap Fillers facilitate high-volume production speeds while sacrificing nothing in the way of thermal management capability. Two-part Gap Fillers are dispensed quickly, flow in and around even the most delicate circuitry, form in place and compensate for the large tolerances between the heat-generating device and its housing or heat sink counterpart.

Minimal Waste

Gap Fillers are only dispensed where needed in the desired thickness and pattern, keeping material waste to a minimum. 

 

As the materials are two-part with activation occurring only when each component is mixed, Gap Fillers are on-demand products used only in the desired volumes as needed, which reduces material waste significantly.
