Industrial Applications

1. Lithium-ion Battery Cell Leak Detection

Utilized in the quality control phase of Li-ion battery manufacturing to perform precision leak testing on battery pouches and cylindrical cells. The sensor monitors the minuscule flow of nitrogen escaping from improperly sealed cells. Its construction adheres to the F1a standard, avoiding copper, zinc, and nickel contamination.

Problem Solved

Prevents catastrophic battery failures and electrolyte dry-out by detecting micro-leaks down to 0.002 l/min, while strictly adhering to the material constraints required for safe Li-ion battery manufacturing environments.

2. Semiconductor Micro-Die Pick-and-Place Verification

Integrated into semiconductor handling systems to monitor vacuum levels and bypass flow during the gripping of microscopic chips. Because the sensor operates effectively in vacuum conditions down to -0.9 bar and holds an ISO 14644-1 Class 4 cleanroom certification, it is safely deployed directly over wafer handling lines.

Problem Solved

Resolves the unreliability of standard pressure switches when handling tiny micro-dies, as the SFAH precisely measures the minute flow differences (under 0.1 l/min) indicating whether a microchip has been successfully gripped or dropped.

3. Medical Device Micro-Catheter Integrity Testing

Employed in medical cleanroom assembly stations to pressure test micro-catheters and miniature fluidic channels. Compressed air is introduced at up to 10 bar, and the sensor measures the leakage rate using its high-precision thermal mass flow principle. Data is continuously logged to a PLC via the IO-Link interface.

Problem Solved

Detects microscopic manufacturing defects and imperfect seals in life-critical medical devices by identifying ultra-low continuous leakage flows that traditional pressure-decay testing might miss due to volume expansion.
