Your advantages with our test adapters
For common requirements we offer the 3 construction types BAL, PRL, POL and IDL. Completely individual constructions are also possible. The shape and size of all of our test adapters are always individually adapted to the assembly to be tested. Thanks to the additive manufacturing process, special features can be easily taken into account.
This not only applies to unusual designs of the test objects, but also to special features of the test fixtures such as:
- Display and controls in the test adapter
- Exemptions from certain areas of the examinee
- Sensors in the test adapter
- Test needles from any manufacturer or we will make a suggestion
- Contacting test points, pads, vias, solder joints, connectors, …
- Lateral contacts
- Permanently installed electronic components in the adapter (e.g. ISP, measurement cards, multiplexer, etc.)
This BAL design was specially developed for small circuit boards. Double-sided contacting is also possible with this.
The PRL design is particularly suitable for small and medium-sized boards. It is characterized by very good usability and good accessibility of the circuit board when clamped.
The POL design is suitable for large boards. It can hold down the circuit board at any point and make double-sided contact if necessary. The robust mechanism allows contacting hundreds of test points.
This IDL test adapter was specially developed for very large boards. A robust adapter that reliably contacts even large quantities of very large circuit boards.
Are your requirements too individual for our standardized construction methods? Then we are happy to create individual constructions. This is worthwhile, for example, for assemblies that are installed in housings or if individual plugs have to be contacted.

Simply calculate the expected costs yourself using our price calculator. We ask for your understanding that the costs for individual requirements may vary.
Send us your requirements. In particular we need:
- Number of test points
- Dimensions and shape of the board
- Information about large, heavy or protruding components
- Connectors to be accessible
- Do currents flow above 1 ampere?
- Special requirements
We accept all of the following data formats:
Photos / Screenshots / Drawings
3D data of the test object (.stp / .iges)
2D data of the test object (.dxf)
Questions / Offer
We do our best to settle all outstanding queries and send you a binding offer within 24 hours.
When ordering, we ask you to provide a test specimen for test purposes. This will be returned to you in sound condition upon delivery of the adapter.
Development / Manufacturing
As soon as your order is in, we begin designing your adapter. Once your test specimen arrives, we are able to check the tolerances and smooth functioning of the device and its production can be completed.
Within the agreed delivery time, we will hand over your test adapter to a suitable shipping service provider.
