Test of printed electronics

Printed electronics are moving boundaries for electrical components by being smaller, thinner, and even transparent at a level where the human eye cannot detect errors.

At Mekoprint we aim to ensure that every component we produce is 100% functional before it reaches your factory. We achieve this through a combination of electrical testing systems and automated optical inspections.

Roll-to-roll electrical function test

The adoption of flying probe technology have marked a significant improvement in our testing of printed electronics. Electrical function test is carried out roll-to-roll, with programmable probes that move across the foil to specific points programmed in test specifications.

Previously, a physical "bed of nails" setup was needed for testing various points on the printed component. This setup had to be customised for each product, which was both costly and time-consuming.

Now, with roll-to-roll electrical function test, we are not tied down to physical tooling. We can set up the tests exactly as needed for each individual customer.

Customised test options

Our state-of-the-art flying-probe technology perform electrical testing of our printed electronics components on rolls.

We are committed to ensure that components produced in high volumes are fully functional and tested in various ways either with a complete electrical test on final products and/or regular testing throughout the manufacturing process.

Testing the ability of a component to store an electrical charge. This test is essential for assessing the performance of capacitors and circuits that rely on capacitive elements.

Accurate measurement helps ensure stability and functionality in electronic devices.
Determines how much a material or component opposes the flow of electric current. It's crucial for verifying the electrical integrity and specifications of resistors and conductive paths.

Consistent resistance levels are key to device reliability.
Testing the ability of a component to induce a voltage as a result of a changing current.

Influencing how effectively the component can manage current changes in circuit applications.
Detecting interruptions in electrical traces.

Essential to ensure there are no breaks that could disrupt the electrical continuity and affect the performance of electronic circuits.
Identifies unwanted connections between conductive traces that should be isolated.
Checking individual electronic parts for functionality and compliance with technical specifications.

"The electrical test setup enables us to quickly and effectively ensure that rolls of printed electronics are 100% tested before sending to our customers. It is future-proved for the new generations of flexible and stretchable sensors, that are much more complex than their predecessors."

Advantages of flying probe technology

Flying-probe technology allows us to create test designs tailored to your specifications, offering multiple benefits in effectively managing the more complex demands of the next generation of roll-to-roll printed electronics and sensors.

Enabling test of larger volumes in less time
Ensures high precision in testing
Reduces initial costs by eliminating the need for specialised tooling

Increasingly complex printed solutions

The growing use of printed electronics technology across consumer products, industrial machinery, wearable technology, and other industries, means increased attention on our capabilities.

During recent years we have experienced a shift from simple solutions to more complex solutions. Fine line conductive traces, and materials with flexible and stretchable features has boosted the need.

Advanced solutions incorporating high levels of detail requires precise process control.

Our test procedure eliminates uncertainty, and guarantee a thoroughly-tested printed electrical component. Ready for in-line, high volume production and at a competitive price.

A number of our customers have already benefited enormously. Are you interested in further dialogue on how we can assist in your project?
