The IDL (Industrial Line) expands the ELOPRINT range with a robust adapter, ideal for large PCBs with many test points. Its aluminum frame ensures high stability and precision, while the CNC-milled needle bed enables reliable electrical contacting. The adapter opens with a rotating motion and closes linearly, pressing the test needles in gently without shear forces.
Available in standard sizes 200×200 mm and 300×300 mm as well as individually for very large circuit boards
Double-sided contact possible
Interchangeable needle bed/hold-down device
Custom interface
Large installation space in the adapter for components such as in-system programmers or measuring electronics
Robust frame made of aluminum strut profiles
Adaptable through sensors, switches, display elements (LEDs/displays), switching contact pins (for detecting the presence of the test object)
Guidance of the board via the external geometry or using catch pins
This test fixture has a test area of 300 x 480 mm. It is used for testing a panel. To keep the complexity of the test fixture and the evaluation electronics low, the panel is not fully contacted but only row by row, allowing it to be gradually removed, repositioned, and contacted again.
Compact and complex
This IDL adapter had to fit into a small space and is therefore smaller than the standard sizes. At the same time, it has many functions, such as contact in three directions (bottom, top and side). Inside, 23 LEDs are guided to an evaluation module via flexible light guides. It can also be pneumatically locked and opened. The lock protects the operator from high voltages and ensures that programming and testing of the test object can take place without interruption. Incorrectly tested DUTs can only be removed after manual confirmation, which prevents them from being accidentally sorted into the good parts. The pneumatic opening serves as a convenience function and is intended to speed up the test process. Additional shock absorbers enable a soft stop when opening automatically.
Side contact
The circuit board to be tested is already in a housing. Here you can see the side contact, which automatically moves to the test object when the adapter is closed. In this way, for example, connector pins can be contacted with test contact pins, but it is also possible to contact connectors using matching mating connectors. This is particularly common for USB-C sockets.
Additional modules
Thanks to the practical aluminum strut profiles, attachments, such as in this case a holder for buttons and a display, can be added without any problems. Of course, we are also happy to create the necessary hardware and software to carry out the test routine and control the display if required
Stability and precision
The IDL (Industrial Line) expands ELOPRINT’s range with a robust adapter that reliably contacts even large quantities of very large circuit boards. With a frame made of aluminum strut profiles, it guarantees maximum stability and precision. The CNC-milled needle bed enables reliable electrical contacting of even the smallest test points.

Various innovation
The IDL offers standard sizes (200 x 200 mm and 300 x 300 mm) and meets individual requirements. The folding mechanism ensures easy access to test contacts and test object holder. With its user-friendly functions, double-sided contacting and optional integration options, the IDL sets new standards for circuit board testing.
