Abstract: A printed circuit board Assembly (PCBA), including at least one crystal oscillator and a printed circuit board (PCB), is provided. The crystal oscillator includes a body and a shell. The shell covers the body. The PCB includes at least one inserting area and at least one plated hole. The inserting area is used for receiving the body. The plated hole is disposed on the inserting area. When the PCBA is under wave soldering process, the solder is drawn from one side of the PCBA to another side via the plated hole for enabling the shell to be electrically connected to the bare copper of the inserting area via the solder. Consequently, the shell has an even better shielding effect, and the EMI effect is reduced.

Abstract: A disk drive for reading a disk is provided. The disk drive includes an optical pickup unit and a spindle motor. The optical pickup unit is disposed below the disk to read data of the disk. The spindle motor carries and drives the disk to rotate, so that the optical pickup unit is able to read the data from different areas of the disk. The spindle motor includes a motor portion and a turntable. The motor portion drives the turntable to rotate. The turntable is used for carrying a disk. The turntable includes a body and several slots. The slots are spread over the disk uniformly and symmetrically. Each of the slots is equipped with several anti-vibrating bodies. When the turntable rotates at high speed, the anti-vibrating bodies collide with one another to reduce the energy of tilting to prevent the turntable from tilting.
