Your advantages with our test adapters

Fast

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

Cheap

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 adapters are particularly inexpensive.

ESD protection

For use in ESD-protected areas, our test adapters 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 adapter.

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 adapter 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 adapters 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.

Our printing processes

FDM offers a variety of materials, versatile design possibilities, and affordable as well as easy handling.

FDM (Fused Deposition Modeling)

MSLA (Masked Stereolithography)

MSLA offers the highest level of detail, smooth surfaces, rapid layer curing, and is ideal for intricate components and small batch production.

SLS offers high strength, precision, and the production of complex shapes, making it ideal for durable test fixtures.

SLS (Selektives Lasersintern)

Inkjet

Inkjet enables precise complex geometries using UV-curable photopolymer droplets and water-soluble support material.

Individual features

Thanks to the additive manufacturing process, special features in the needle adapter can be easily taken into account, be it for unusual designs of the test objects or special requirements for the test adapters:

  • Display and controls in the test adapter
  • Side contacts
  • Sensors in the test adapter
  • Exemptions of certain areas of the examinee
  • Test needles from any manufacturer or we make a suggestion
  • Permanently installed electronic components in the needle adapter (e.g. ISP, measurement cards, multiplexer, etc.)
  • Contacting of test points, pads, vias, solder joints, connectors, …
