Abstract: The disclosure discloses a crystal device without an external package, which comprises: a crystal body (21) and two pins (22), wherein the crystal body (21) is a cylindrical body port of a crystal with the external package (15) and redundant pins (12, 13) being removed, and is arranged on a Printed Circuit Board (PCB) horizontally. The two pins (22) are connected to a bottom end of the crystal body (21). Extension parts of the two pins (22) are inclined towards the PCB, and become horizontal when they reach the PCB and are welded to the PCB, and a spacing between the two pins (22) increases gradually. The disclosure also discloses a method for manufacturing a crystal device without a package. The device and method can reduce the cost and make the welding more convenient.
