Abstract: A package structure and a formation method of a package structure are provided. The method includes disposing a chip structure over a substrate. The chip structure has an inclined sidewall, the inclined sidewall is at an acute angle to a vertical, the vertical is a direction perpendicular to a main surface of the chip structure, and the acute angle is in a range from about 12 degrees to about 45 degrees. The method also includes forming a protective layer to surround the chip structure.

Abstract: A signal contact member and a ground contact member to which a center conductor and an outer conductor of a coaxial cable are connected are supported by an insulating housing member. The ground contact member has an annular fitting portion that fits and connects to the ground contact portion of a mate connector device. The annular fitting portion is provided with an opening for disposing a center conductor connection portion of the signal contact member. A shell portion of a ground contact member or an insulating housing member is provided with a conductive member given a ground potential. The conductive member partially fills the opening in the annular fitting portion.

Abstract: A method of manufacturing an electrical connector includes: contacting an end portion of a center conductor exposed in an end portion of a coaxial cable having the center conductor with a conductive contact; applying ultrasonic vibration to the end portion of the center conductor and the contact to join the end portion of the center conductor and the contact each other; and accommodating the contact in an insulation housing after the end portion of the center conductor and the contact are joined to each other, and covering at least a part of a joint of the end portion of the center conductor and the contact with the insulation housing.
