Abstract: An electronic load device includes a main board and a load module. The main board has a plurality of first connecting ports. The load module includes a sub board and a heat-dissipating unit. The sub board has a second connecting port and a pin-hole port. The second connecting port is used for detachably connecting one of the plurality of first connecting ports. The pin-hole port is used for connecting a power component. The heat-dissipating unit has a cylindrical body and a plurality of heat-dissipating fins. The cylindrical body is defined with an outer surface and an inner surface opposite to the outer surface. The plurality of heat-dissipating fins is connected with the outer surface. When the power component is connected to the pin-hole port, the power component contacts the inner surface.

Abstract: Herein disclosed is a voltage dividing resistor comprising a resistance bar and a plurality of dividing connectors. The resistance bar has a first end and a second end and provides a first current path, which stretches from the first end to the second end along the resistance bar. The distance between the first end and the second end is less than the length of the first current path. The first and second ends are configured to be electrically connected to a power source. The dividing connectors are electrically connected to different locations on the first current path. Each of the dividing connectors has a contact pad. The resistance bar is not coplanar with the contact pads. A divided voltage is obtained from a pair of dividing connectors chosen from the plurality of dividing connectors.

Abstract: A support apparatus is configured to support electronic components. The support apparatus includes a tray and a plurality of recessed structures. The tray has a cavity therein and at least one intake hole communicated with the cavity. The recessed structures are disposed on the tray and recessed toward the cavity. Each of the recessed structures is configured to accommodate at least a part of a corresponding one of the electronic components and includes a support surface and a plurality of first spacers. The support surface has an exhaust hole communicated with the cavity. The first spacers are disposed on the support surface of a corresponding one of the recessed structures. When a corresponding one of the electronic components is supported on the first spacers, any adjacent two of the first spacers and the corresponding electronic component form a first flow channel.

Abstract: An electrical probe includes a base body and a probe head. The base body has a main body portion and at least one positioning portion, and the positioning portion protrudes from the main body portion. The probe head is detachably disposed on the main body portion of the base body. The probe head has an outer edge away from a side of a central axis of the main body portion, and the positioning portion protrudes from the outer edge.
