Thermal Paste Dispenser for 5G Base Station Assembly

Product Specifications

Technical details and manufacturing context for Thermal Paste Dispenser

Definition

The Thermal Paste Dispenser is a specialized automated dispensing system used within the Modular 5G Base Station Production System. Its primary function is to precisely deposit controlled amounts of thermal paste onto heat-generating electronic components, such as processors, RF modules, and power amplifiers. This ensures optimal thermal conductivity between the components and their heat sinks, which is critical for maintaining 5G base station reliability and performance under high thermal loads.

The dispenser operates using pneumatic or servo-driven positive displacement mechanisms, typically syringe-based with precision nozzles. It extrudes thermal paste in predetermined patterns and volumes, controlled by programmable logic controllers (PLCs) or robotic systems that coordinate with production line timing. This ensures consistent application thickness, coverage area, and placement accuracy according to component specifications.

Key parameters include a dispensing volume range of 0.01–5.0 mL per cycle, with a repeatability accuracy of ±0.01 mL. Operating pressure is 1.0–1.6 MPa. Dispensing speed ranges from 0.1–5.0 mL/s. The system operates in ambient temperatures of 5–40 °C and non-condensing humidity of 20–80% RH. Power supply is 220–240 V AC (50/60 Hz), with power consumption of 300–500 W. Clean dry air supply is required at 0.5–0.7 MPa. The machine weighs approximately 150–200 kg and has a footprint of 800×800×1600 mm (L×W×H).

Materials used in construction include stainless steel for fluid path components, PTFE/Teflon for seals and wetted parts, aluminum alloy for the structural frame, and ceramic or hardened steel for nozzle tips. The control system features a touchscreen interface with PLC.

For procurement, verify model-specific values and standards with the legal manufacturer or supplier, as the listed parameters are reference ranges. The dispenser is a component within a larger production system and is not a standalone product for end users.

Working Principle

The dispenser uses pneumatic or servo-driven positive displacement mechanisms, typically syringe-based with precision nozzles, to extrude thermal paste in predetermined patterns and volumes. Controlled by PLCs or robotic systems, it coordinates with production line timing to ensure consistent application thickness, coverage area, and placement accuracy according to component specifications. The system operates within defined pressure, temperature, and humidity ranges to maintain repeatability.
