Full visibility in manufacturing and supply chain

In modern electronics manufacturing, the processes at play are incredibly dynamic. Component changes, test system maintenance, environmental factors, different test operators, unit firmware, to name a few translates into a huge range of potential causes of a product of reduced quality. The modern KPI toolbox for Quality Assurance must facilitate full transparency into all of these, alongside a well-balanced ability for early intervention. 

By selecting WATS we gain real-time information from all our production sites globally.

Unit Verification

When all test data is readily available, you can also instantly check if a given unit has been tested as required. With the help of Unit Verification Rules, you can be sure that no product leaves the factory or supplier unless all tests are performed, in the correct order, and passed. Advanced organizations can also programmatically design strict manufacturing processes to reduce the possibility of human errors during manufacturing, with the Workflow Module.*

*WATS Workflow Module is currently only available for on-premise installations.

Monitor your test policy

Excessive product retesting is an unfortunate situation, that many companies are completely unaware of, and that goes against their test policy. This problem exists both in in-house manufacturing, as well as outsourced. Very often, the problem exists due to an inability to use data to improve the test systems and is allowed to continue because the extent of retesting is not visible. By understanding the specific performance of test equipment, you can easily remove the trivial causes of test failures, also eliminate the arguments to perform retesting. You can also easily gauge the frequency of retesting and evaluate if additional corrective actions are necessary.

Optimize Test Coverage

A product test is only as good as its coverage. And unfortunately, this coverage is not always scientifically determined. Test limits are often determined based on a combination of ideal component specification and past experience. And very often these test limits are deployed as-is, with little or no adjustments. On the one hand, this can cause false failures. But on the other hand, this often leads to test limits that are very forgiving and allows faulty products to pass undetected. WATS gives you the ability to analyze these trends so that you can make informed decisions on updating test software and test limits. And avoid unnecessary factory escapes.

RMA/Warranty Analysis

Units that are returned from the field represents the highest possible cost when dealing with failures introduced during design or manufacturing. By having full traceability of the origin of a product, you also hold power to understand what took place during the inception of individual units or groups of units, and that might have caused them to fail at a later time. We have seen customers reporting an astonishing 97% decrease in warranty claims after introducing WATS.

Asset Management

Keeping track of the maintenance status of your test equipment goes beyond simple calibration data management. An Automated Test Equipment rack contains multiple instruments, together with interfaces and connections. All of whom has different calibration intervals, cleaning intervals and pin-replacement intervals. WATS gives you the ability to design the detailed maintenance specification of all of your test components and translates test reports into usage data. You will have quick and easy access to both the overall and detailed maintenance status of all your test assets.
