Abstract: A key structure includes a keycap, a connection assembly, engaging members, and a base plate. The connection assembly disposed between the base plate and the keycap is movably connected to the keycap and the engaging members, so that the keycap and the connection assembly engaged with the engaging members are positioned on the base plate. The base plate includes engaging protrusions protruding from an upper surface, so that the engaging members are bonded to the base plate through the engaging protrusions. Each engaging protrusion is located between two openings of the base plate, connects the two openings, or is disposed corresponding to the openings. Each engaging member covers one or more engaging protrusions through injection molding, and is fixed to the base plate. The engaging members are respectively disposed on the openings, fill the openings, or completely cover the engaging protrusions.

Abstract: A key is disclosed herein. The key is disposed on a baseplate of a keyboard device, and comprises a sheet metal keycap and a supporting structure. The sheet metal keycap includes a body portion and two bending portions. The two bending portions are formed by extending downward from a side of two punching holes on the body portion, respectively. The supporting structure is disposed between the sheet metal keycap and the baseplate. Two sides of the supporting structure are pivotally connected to the bending portions and the baseplate, respectively. The key is thinner due to sheet metal keycap which is integratedly formed. A keyboard device with a plurality keys is also provided herein.

Abstract: A key structure includes a base, a keycap, and a connecting rod. The base includes a structural plate and a connecting plate. The connecting plate is configured on the structural plate. The keycap is configured on the structural plate and includes a plate body and a first hook. The connecting rod is configured under the structural plate and extending towards an extension direction. The connecting rod includes at least a second hook. The connecting rod moves along the extension direction relative to the base to drive the second hook to be fastened to or detached from the first hook. When the first hook is detached from the second hook, the keycap moves relative to the connecting rod to expose the space between the keycap and the base, and then the key structure is easily repaired or cleaned.

Abstract: A key structure is provided. The key structure comprises a substrate, a membrane circuit disposed on the substrate, a conduction switch disposed on the membrane circuit, a keycap, a bending portion fixed to the keycap, an elastic member disposed on the membrane circuit and abutting against the keycap, and a connecting rod disposed movably between the membrane circuit and the keycap. The connecting rod includes an operating arm and an engaging portion. The operating arm is connected to the engaging portion, and the engaging portion selectively engages with the bending portion. When the operating arm moves in a direction parallel to a surface of the keycap, the operating arm drives the engaging portion to disengage from the bending portion and the elastic member provides a force against the keycap to move the keycap away from the conduction switch.

Abstract: A semiconductor test system having a tester and a prober and the test method thereof are proposed. A test mark signal and a control board having a discrimination circuit and a protection circuit are added to a test connection interface of the tester. When performing multi-chip test, the connection result is displayed after checking the test mark signal by the discrimination circuit. Whether the test can be performed or not is then determined by the protection circuit. When the interface connection is incorrect due to man-made carelessness, an alarm will buzz for warning, and the protection circuit will be simultaneously activated to disable the tester. Normal test can be performed only if the interface connection is correct. Thereby, the correctness of the test results can be ensured to reduce returned purchase and to enhance the quality of production.
