Thermal conductive gel application case: How does the dispensing equipment apply adhesive to the heat sink?

In automated production, the key to applying thermal grease to heat sinks using dispensing equipment lies in the precise control of the amount of grease, the application path and the equipment parameters. This typically involves three main stages: preparation, dispensing and pressing.

Ι.Automated Dispensing Process?

1. Preparation and Fixing

 Before dispensing, the heat sink base must be fixed to the dispensing machine’s work platform using a dedicated clamp (such as an adjustable baffle) for precise positioning to prevent displacement during dispensing. Simultaneously, the thermally conductive material needs to be connected to the dispensing system.

● Fixing the Heat Sink: First, the heat sink base needs to be fixed to the dispensing machine’s work platform using a clamp for precise positioning to prevent displacement during dispensing.

● Connecting the Dispensing System: The dispensing of thermally conductive gel is usually packaged in 30cc, 55cc syringes, or drum larger containers, and directly connected to the dispensing machine’s dispensing system.

● Material Type: Thermally conductive silicone grease; Dispensing Form: Syringe, drum container; Characteristics: High viscosity, typically using servo pressure dispensing technology for precise control.
