Abstract: An adapter bracket includes a holder, a first fixing element and a second fixing element. The holder includes first to third strip-shaped bodies. The first strip-shaped body is formed with first notches linearly arranged thereon. The second strip-shaped body is formed with second notches linearly arranged thereon. The third strip-shaped body is formed with third notches linearly arranged thereon. The first fixing element detachably couples the first and second strip-shaped bodies together, so that the first and second strip-shaped bodies are in contact with each other, and the first and second notches are jointly combined into a plurality of first fastening holes. The second fixing element detachably couples the second and third strip-shaped bodies together, so that the third and fourth strip-shaped bodies are physically connected together, and the third and the fourth notches jointly combined to form a plurality of second fastening holes linearly arranged.

Abstract: An adapter bracket includes a holder and a fixing element. The holder includes a first strip-shaped body and a second strip-shaped body. The first strip-shaped body is formed with a plurality of first notches linearly arranged on a first coupling surface of the first strip-shaped body. The second strip-shaped body is formed with a plurality of second notches linearly arranged on a second coupling surface of the second strip-shaped body. The fixing element detachably couples the first strip-shaped body and the second strip-shaped body together, so that the first coupling surface and the second coupling surface are in contact with each other, and the first notches and the second notches are jointly combined into a plurality of fastening holes arranged linearly, and each of the fastening holes can hold an object therein.

Abstract: Herein disclosed is a test head connection method, the method comprises the following steps. First, a load board and a card holder are provided between a test head and a probing machine, the card holder is disposed in the probing machine, and the card holder is used to accommodate the load board. A vacuum function of the test head is activated, and the test head is moved to align the card holder. The test head is moved to touch the load board in the card holder. At least one clamping piece is used to fix the test head and the card holder. Wherein the load board and a wafer are connected by direct probing.
