CLAMPOF PLASMA CLEANING DEVICE

摘要

PURPOSE: A clamp of a plasma cleaning apparatus is provided to prevent damage of a solder ball and burning damage by minimizing a space of a lower part and the solder ball of the lower surface of a printed circuit board. CONSTITUTION: A plurality of mounting grooves(111) is formed on the center region of the upper surface of a bottom plate. A guide groove(112) is respectively formed on both side regions of the upper surface of the bottom plate by being separated by the mounting grooves. A compression spring is vertically installed on the guide groove. A pressurizing unit(130) is combined in order to be penetrated by the compression spring on the guide groove. Both ends of a printed circuit board are clamped by the pressurizing unit. The printed circuit board is horizontally maintained by pressing the upper part of the pressurizing unit.
