Abstract: A carrier structure is provided with a plurality of package substrates connected via connecting sections, and a functional element and a groove are formed on the connecting section, such that the groove is located between the package substrate and the functional element. Therefore, when a cladding layer covering a chip is formed on the package substrate, the groove can accommodate a glue material overflowing from the cladding layer to prevent the glue material from contaminating the functional element.

Abstract: A lash brush includes a case, a rotatable shaft, a plurality of bristles and a reciprocating transmission mechanism, the rotatable shaft is driven into reciprocal motion along an axial line by the reciprocating transmission mechanism, a first unit of the reciprocating transmission mechanism comprises an actuating surface having a plurality of spacing members, a second unit of the reciprocating transmission mechanism comprises a contacting terminal contacting against each of the spacing terminals in sequence to make the rotatable shaft vibrate back and forth instantaneously along the axial line.

Abstract: A coil structure for a coreless motor includes a plurality of first conductive traces and a plurality of second conductive traces. The first conductive traces are disposed in succession relative to one another, and are each arranged into a planar spiral configuration having a substantially polygonal shape. At least one adjacent pair of the first conductive traces cooperate to define a space therebetween. Each of the second conductive traces is disposed in the space defined by a corresponding adjacent pair of the first conductive traces, and is arranged into a planar spiral configuration that has one of a substantially triangular shape and a substantially rhombic shape so as to substantially fill the space.

Abstract: A testing system for a device under test (DUT) includes a test parameter-generating device and a platform module. The test parameter-generating device stores test information, and is operable so as to execute a test algorithm, so as to generate a transmission signal upon execution of the test algorithm, and so as to generate a test environment with reference to the transmission signal. The platform module is operable so as to conduct testing of the DUT using the test information stored in the test parameter-generating device under the test environment generated by the test parameter-generating device.
