Abstract: A package structure includes: a substrate includes a first surface; a semiconductor chip disposed on the first surface; a support disposed on the first surface and surrounding the semiconductor chip comprises an electrical conducting member and penetrating the support; and an optical component disposed on the support and electrically connected to the substrate by the electrical conducting member.

Abstract: An RF chip test method is disclosed. The RF chip test method includes disposing an RF chip within a chip socket, with the RF chip having at least one RF pin and at least one non-RF pin, the chip socket having conductive elements, and the conductive elements contacting the RF pin and the non-RF pin; connecting the non-RF pin to a ground end and connecting the RF pin to an RF measuring instrument; measuring a S11 parameter of the RF pin using the RF measuring instrument; and comparing the S11 parameter with an allowable range so as to judge the contact condition between the RF pin and the conductive element.

Abstract: The present invention provides a universal connector for a pneumatic tool with unlocking by air flow. A directional locating member is mounted between the sleeve and the first coupler, or the pin-joint member, so the sleeve can be securely locked when located at the first position. Available at first and second positions, the second coupler of the universal connector can be positioned in the absence of aeration, or reset automatically after aeration, thus achieving unlocked by air flow purpose. This ability provides easier and convenient assembly or disassembly of the universal connector and pneumatic tool without needing any controlling members, thus guaranteeing improved ease-of-operation and higher applicability.
