VC Water Bath Bubble Leak Tester

VC Water Bath Bubble Leak Tester for Vapor Chamber Production

Product Description

The VC Water Bath Bubble Leak Tester is a dedicated quality control machine used in vapor chamber (VC) manufacturing. It detects seal integrity defects by pressurizing the sealed VC internally and submerging it in a water bath — any leakage point becomes immediately visible as a stream of rising air bubbles.

With independent pressure control per station (1–5 KG), adjustable inflation and detection time, and compatibility with VC products up to 300×300mm, this machine delivers reliable, repeatable leak detection results that protect downstream production from escaping defective units.

Key Features & Technical Advantages

1.Independent Air Pressure Control per Station

Each test station is equipped with its own independent pressure regulator, adjustable from 1 to 5 KG. Multiple vapor chamber products with different pressure specifications can be tested simultaneously — no manual switchover required between product types.

2. Programmable Inflation & Detection Time

Both inflation time (pressurization cycle) and detection hold time are independently configurable via the control panel. Operators can fine-tune the cycle to match VC wall thickness, cavity volume, and production takt time requirements without compromising test sensitivity.

3. Instant Visual Leak Location

Water bath bubble testing provides immediate, operator-readable confirmation of both leak presence and exact leak location. Unlike pressure decay methods, this technique lets operators pinpoint the defect site in seconds — enabling rapid rework decisions on the production line.

4. Wide Product Size Compatibility

The machine accommodates vapor chamber products up to 300×300mm, covering standard VC sizes used in server CPUs, AI accelerator modules, GPU thermal solutions, and high-power LED cooling systems.

5. Robust Industrial Build

The 1800×900×1800mm machine frame is engineered for continuous production line operation. The water bath chamber is designed for easy drain-and-refill and uses corrosion-resistant materials for long service life in high-humidity workshop environments.

FAQ

What is a VC water bath bubble leak tester?

It is a quality control machine used in vapor chamber (VC) manufacturing to detect seal leaks by internally pressurizing the VC and submerging it in a water bath — leaks are visible as rising air bubbles.

The standard machine supports VC products up to 300×300mm. Custom larger sizes are available on request.

Yes. Each station has fully independent pressure adjustment from 1 to 5 KG, allowing simultaneous testing of different VC product types.

Yes. Since inflation pressure is adjustable down to 1 KG and both inflation and hold times are programmable, the machine can be safely operated without over-pressurizing thin-wall VCs.

The machine operates on AC 220V with a power consumption of 1.5 KW — standard industrial power supply, no special electrical installation required.
