Your advantages with our test fixtures

Fast

Thanks to the design, manufacture and assembly of our needle adapters in-house, we are independent of external suppliers. The first test fixtures can be delivered within 1-3 weeks.

Affordable

Thanks to the 3D printing-optimized designs of our needle adapters, our costs are well below the market average. Since we only calculate our development costs once, additional, identical test fixtures are particularly inexpensive.

ESD protection

For use in ESD-protected areas, our test jigs are provided with a special coating or are optionally made entirely of special ESD material.

Flexible

Circuit boards? Individual components? Assemblies? Entire devices? We develop and produce the appropriate test jigs.

Compact

Our compact and robust needle adapters can be integrated into almost any production line.

Maintenance-free

Our needle adapters are designed for several million cycles without maintenance. Only the test contact pins have to be replaced after 10,000 to 100,000 cycles, depending on the application. The replacement is usually carried out without special tools.

Test fixture designs

For common requirements, we offer needle adapters in the 4 designs BAL, PRL, POL and IDL. Completely customized needle adapters or mounting devices are also possible. The shape and size of all our test jigs are always individually adapted to the assembly to be tested. Thanks to the additive manufacturing process, special features in the needle adapter can be easily taken into account.

BAL

This BAL design was specially developed for small circuit boards.

Double-sided contacting is also possible with this.

Inquiries / Offer

We always endeavour to process your queries within 24 hours in order to be able to provide you with an individual offer for your needle adapter as quickly as possible. If you have any queries, you can reach us at the email address info@eloprint.de, the telephone number +49 711 50480481 or via the following contact form.

Step 4

Order

When ordering, we ask you to provide a test sample for testing purposes. This will of course be returned to you undamaged together with the needle adapter.

Step 5

Development / Manufacturing

As soon as we receive your order, we start designing your test fixture. Once we receive your test piece, we can check the tolerances and smooth functioning and then production can be completed.

Step 6

Delivery

We will hand over your test jig to a suitable shipping service provider within the agreed delivery time.
