The interposer 421 has a wide-pitch connection surface 4211 and a wide-pitch interconnection surface 4212 on opposite sides (e.g., bottom and top sides of the interposer 421 in fig. 2) and electrically coupled to each other; the spacing and arrangement between the first plurality of inner contacts 4213 of the wide inner contact surface 4212 is substantially equal to the spacing and arrangement between the plurality of contacts (not shown) of the wide connecting surface 4211.

Wherein the top gasket 423 is annular and elastic, and is disposed at an outer side portion of the narrow-pitch connecting surface 4221 (for example, the plurality of contacts of the narrow-pitch connecting surface 4221 are surrounded by the top gasket 423 and are exposed outside the housing 41); that is, the top gasket 423 is clamped between the housing 41 and the fan-out adapter plate 422 (e.g., the narrow-pitch connection surface 4221).
Accordingly, the holder 100 in the present embodiment is electrically coupled to the rotating board module 4 and the circuit board 1 through the plurality of conductive adhesive columns 33 of the connection layer 3, so that the existing welding manner is replaced by the detachable connection layer 3 between the rotating board module 4 and the circuit board 1, and thus the detachable connection layer is detachable from each other for facilitating subsequent use (e.g. maintenance and replacement or transfer to other components).

More specifically, the positioning plate set 201 includes a spacer 2011 mounted on the outer frame 2, an upper guide 2012 disposed outside the spacer 2011, and a lower guide 2013 disposed inside the spacer 2011.

Furthermore, the upper guide plate 2012 and the lower guide plate 2013 are mutually matched, and are fixed with a plurality of conductive probes 202 for abutting against and electrically coupling with the narrow-pitch connection surface 4221 of the rotating plate module 4, but the invention is not limited thereto. For example, as shown in fig. 6, the number of the rotating plate modules 4 can be increased, and the rotating plate modules 4 are also disposed in the accommodating space S surrounded by the circuit board 1 and the outer frame 2, and the probe head 200 and the connection layer 3 are correspondingly adjusted.
Example two
Please refer to fig. 7, which illustrates a second embodiment of the present invention.

Accordingly, the rotating board module 4 in the present embodiment may be formed by the first annular step 411 and the second annular step 412 of the housing 41, so that the components (such as the interposer 421, the fan-out interposer 422, and the top gasket 423) in the circuit fan-out structure 42 can be precisely positioned on the connection layer 3, thereby ensuring electrical connection therebetween.
Example III

Since this embodiment is similar to the first embodiment, the same parts of the two embodiments will not be described again, and the differences between the present embodiment and the first embodiment are described as follows:
in the present embodiment, the circuit fan-out structure 42 does not include the interposer 421 according to the first embodiment; that is, the circuit fan-out structure 42 may be a single board body (such as the fan-out interposer 422) or may include only the fan-out interposer 422 and the top gasket 423, but is not limited thereto.
Specifically, the circuit fan-out structure 42 has the wide-pitch connection face 4211 located at the opposite side and the narrow-pitch connection face 4221 electrically coupled to the wide-pitch connection face 4211. That is, the fanout inner face 4222 of the fanout interposer 422 of embodiment one is used herein as the wide pitch connection face 4211 of the circuit fanout structure 42. The second ends 332 of the conductive adhesive columns 33 are abutted against and electrically coupled to the wide-pitch connection surface 4211, and the conductive probes 202 are abutted against and electrically coupled to the narrow-pitch connection surface 4221, and further electrically coupled to the circuit board 1 through the circuit fan-out structure 42 and the conductive adhesive columns 33.

Further, the rotor board module clamps the fan-out adapter board by adopting the interposer and the housing, so that the fan-out adapter board can reduce the horizontal deformation degree (i.e. maintain the better levelness) of the fan-out adapter board after the detachable testing device is assembled.
Furthermore, the holder can be further provided with elastic members (such as the bottom gasket, the filling body, and the top gasket) at appropriate positions among the plurality of members, so that the corresponding members can be expected to deform due to force balance, and the horizontal deformation degree of the fan-out adapter plate can be effectively reduced (i.e. better levelness is maintained) after the detachable testing device is assembled, and the plurality of conductive adhesive columns of the connecting layer can be stably connected to the rotating plate module.
