Calibrated micro holes or ‘micro-leaks’ are used to calibrate leak test equipment and/or verify leak test processes.
In order to verify accuracy of leak test equipment or to prove a leak test process works correctly, a confirmed ‘leak’ or ‘positive control package’, as it is otherwise known, must be introduced into the process. Correctly functioning equipment would then identify that introduced leak.
Positive control packages (the product with the micro leak) are used in the development of leak test processes and leak test equipment and as a tool to calibrate leak test equipment.
Positive-control packages are produced by creating a micro-leak directly into the item being tested. For example, in the case of packaging, a hole is created by laser drilling directly into the packaging material. The benefit of producing the positive-control packages in this way is that the defect can be created in a specific location or locations to recreate specific localised faults (for example; on the neck of a pharmaceutical ampoule) or a particular feature could be machined, depending on the test requirements.
Our applications laboratory houses numerous laser micromachining systems which have been designed and built with the capabilities which allow us to machine a wide range of materials, even challenging transparent materials including glass and plastics. Which is why we provide calibrated micro holes to OEMs and packaging manufacturers across the globe.
