Abstract: A method for controlling liquid ingress detection and an electronic device are provided. The method includes: controlling a liquid ingress detection circuit to start liquid ingress detection in a Type-C interface; stopping applying a voltage to first data pins when a detection result of the liquid ingress detection is that liquid ingress occurs in the Type-C interface, and obtaining a first parameter of a screen of the electronic device; when the first parameter of the screen is a screen-off state, controlling the liquid ingress detection circuit to start next liquid ingress detection in the Type-C interface after first duration; and when the first parameter of the screen is a screen-on state, controlling the liquid ingress detection circuit to start next liquid ingress detection in the Type-C interface after second duration, where the first duration is greater than the second duration.

Abstract: The present disclosure relates to a connector and a continuity test device. The connector includes a connector housing having a block portion being provided with a terminal accommodating chamber, and a front holder insertion space being adjacent to the block portion for inserting a front holder that detects terminal half-insertion from a front side. The connector housing is formed with a groove for detecting erroneous fitting into a continuity test device. The groove for detecting erroneous fitting is fitted with a projection provided on the front holder when the front holder is inserted into the front holder insertion space. The groove receives a convex portion provided on a fitting port of the continuity test device when the connector housing is fitted into the fitting port of a continuity test device for a connector without the front holder.

Abstract: A testing system for electrical interconnects having a removable device under test printed circuit board (DUT PCB) that electrically connects with the electrical testing components of the system. A removable top plate is placed on top of the DUT PCB and is locked in place by a plurality of locking posts that selectively connect to cam surfaces in the top plate that pull the top plate down sandwiching the DUT PCB between the top plate and the electrical testing components of the system. An actuator is also presented that presses the device under test into the electrical interconnect at increments where tests are performed on one, some or all of the contact points of the electrical interconnect. This information is then analyzed and graphed to assist with determine the optimum force and/or height to use during actual use.

Abstract: A method for determining a connection status between an antenna amplifier and an antenna structure includes applying a first diagnostic voltage to a connecting link between the antenna amplifier and the antenna structure, reading out a first voltage value at a measuring point of the connecting link, and comparing the first voltage value with the first diagnostic value. The method includes applying a second diagnostic voltage different from the first diagnostic voltage to the connecting link, reading out a second voltage value at the measuring point, and comparing the second voltage value with the second diagnostic voltage. A faulty connection between the antenna amplifier and the antenna structure is determined if the first voltage value corresponds to the first diagnostic voltage and the second voltage value corresponds to the second diagnostic voltage.
