Title: Innovations of Chi Hwan Jeong
Introduction
Chi Hwan Jeong is a notable inventor based in Seoul, South Korea. He has made significant contributions to the field of technology, particularly in sound transmission and probe card design. With a total of 2 patents, his work reflects a commitment to advancing engineering solutions.
Latest Patents
One of his latest patents is an "Apparatus for transmitting and receiving sound." This invention features a directional microphone designed to detect sound for transmission. A sound output unit is strategically placed at a side of the microphone where sensitivity is low. This arrangement effectively prevents sound coupling between the received sound and the transmitted sound, eliminating the need for complex signal processing to reduce echo and howling.
Another significant patent is for a "Probe card having deeply recessed trench and method for manufacturing the same." This innovation allows the probe of the probe card to move only in a vertical direction using a trench. This design enhances electrical and mechanical characteristics while automatically limiting vertical movement within a predetermined range. The invention also enables a reduction in pitch to correspond with decreasing distances between pads, maintaining the flatness of the probe tip within a few micrometers. This technology allows for 32 simultaneous parallel testing, which is a significant improvement over conventional probe cards, and facilitates wafer-level testing, thereby reducing time and costs associated with wafer testing.
