Abstract: A probe module, which supports loopback test and is provided between a PCB and a DUT, includes an adapter, two probes, two inductive components provided at the adapter, and a capacitive component. The adapter has two connecting circuits. An end of each of the probes is connected to one of the connecting circuits, while another end thereof, which is a tip, contacts the DUT. Each of the inductive components has an end electrically connected to one of the connecting circuits, and another end electrically connected to the PCB through a conductive member, which is provided at the adapter, wherein two ends of the capacitive component are electrically connected to one of the connecting circuits, respectively. Whereby, the signal paths are changed by the differences between frequencies of signals, and the transmission path of high-frequency signals is effectively shortened.

Abstract: A cooling system includes a cooling device, a controller and a defrosting unit. The cooling device has a compressor, a condenser, an expander, an evaporator, a cooling channel and a coolant. The coolant is functioned in the evaporator to thermally exchange with a working fluid in a pipe. The controller is adapted for controlling the temperature of the working fluid by controlling the cooling device. The defrosting unit has a switch disposed on the cooling channel and located between the compressor and the condenser, and a defrosting channel connected with the switch. After passing through the switch, the coolant is optionally fed to anyone of the cooling channel and the defrosting channel. After flowing through the defrosting channel, the coolant passes through the evaporator and then flows back to the compressor. As a result, the cooling system is capable of fast defrosting without using a heater.

Abstract: A probe device includes a spring probe having a spring sleeve with at least a spring section and a connection segment fixed to a needle and having a convex portion protruding over an outer cylinder surface of the spring section, and a probe seat having stacked dies and at least a guiding hole through which the probe is inserted. The dies includes a lower die, a supporting die above the lower die and a non-circular supporting hole at the supporting die. The distance between a supporting surface and a center of the supporting hole is greater than the radius of the outer cylinder surface and smaller than the distance between a guiding surface of the supporting hole and the center, which is greater than the maximum distance between the convex portion and a needle center, thereby preventing the probe receiving external force from exceeding deflection and bending.
