Your advantages with our test adapters
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, …
