High-Precision Micro-Volume Eccentric Screw Valve for UV Adhesive Dispensing in VC Vapor Chamber Assembly

Volumetric control Eccentric Auger Valve KSP0450 for VC Vapor Chamber assembly application

The micro-volume eccentric screw valve is an ideal dispensing solution for sealing copper pipes in VC (vapor chamber) heat spreader assemblies. Designed for high-precision applications, it delivers bubble-free, consistent micro-doses of UV adhesive, ensuring complete and uniform sealing around copper inlets. With volumetric control and a servo-driven rotor-stator mechanism, the valve handles medium to high-viscosity UV resins with excellent repeatability and no dripping or pulsing. Its low-shear dispensing protects adhesive integrity and prevents air entrapment, meeting strict requirements for thermal performance and airtight sealing in electronic cooling systems. Compact and automation-friendly, it is perfectly suited for high-volume VC manufacturing lines.

Core Advantages

1. Ultra-small dose output, suitable for the fine sealing requirements of copper pipe mouth
2. Stable and non-pulsing, effectively controlling the consistency of UV glue curing
3. No glue leakage, no wire drawing, ensuring the overall thermal performance and sealing reliability of VC
4. Good material compatibility, UV glue can be used for a long time without corrosion or aging problems
5. Supporting high-speed operation of automated production lines, improving yield and beat efficiency

Main appliaction

• Gluing Vapor Chamber Brass tube
• Pad assembly
• FPC connector PIN
• In-vehicle Camera AA process

FAQ

Q1. Can the eccentric screw valve ensure precise sealing around copper pipe inlets on vapor chambers?
Yes. The valve offers high-precision volumetric dispensing, ensuring uniform adhesive coverage around copper pipe edges without overflow or voids.

Q2. Is the screw valve compatible with UV adhesives used in VC manufacturing?
Absolutely. The valve supports a wide viscosity range and uses chemical-resistant stator materials like FFKM, making it fully compatible with UV-curable adhesives.

Q3. What is the minimum volume the valve can dispense for tight copper pipe applications?
Micro-volume eccentric screw valves can dispense as little as 1 μL per shot, ideal for precise sealing in narrow copper inlet areas of vapor chambers.
