TM Electronics Testing 101 – Leak, flow and package testing


Although Leak and Package Testing are different in their functional approach, the fundamental motivation for testing is the same – to ensure that material that is supposed to remain in a package or product stays there, and that nothing in the outer environment that is not intended to get into the package or product can enter.

Perhaps your product is designed to contain a material without losing any of the contents or to transfer a material or solution intact from one point to another. Perhaps you are introducing a new product that is itself enclosed in a completely sealed package, sterile or otherwise, to protect the product from the world, or to protect the world from your product.

Whatever issue you are facing, it has become apparent that testing is important. Leaks mean product failure. Seal or closure weakness may lead to leaks. A leak or seal weakness may lead to material leakage, environmental contamination, loss of sterility or component failure. In all cases, leaks mean waste of manufactured product, and leaks that are not found will surely lead to customer complaints!
