Description

Technical Field

[0001] This utility model relates to the field of lead frame core material technology, specifically to a degreasing device for the surface of lead frame core material. Background Technology

[0002] The surface of the lead frame core material needs to be kept clean, as oil is a dielectric and has a certain degree of conductivity. If there is too much oil on the lead frame, it may form a conductive path between adjacent pins, causing a short circuit. Therefore, it is necessary to degrease the surface of the lead frame core material. Existing degreasing methods typically use organic solvents.

[0003] Existing lead frame core materials are usually alloy metals. Due to the high quality of the metals, it is difficult to move or hold the metal materials when they are stacked, which increases the difficulty of cleaning and the labor intensity of workers. To address this issue, we propose a degreasing device for the surface of lead frame core materials. Utility Model Content
