一、概述我厂于1985年从日本三洋电机公司引进了二次焊接设备,用于电视机机芯板的自动焊接。机芯板是电视帆的心脏,它电路复杂,尺寸有限,从而焊点小,焊点密度大。以我厂生产的46cm彩色电视机为例,大小为φ2.5mm左右的焊盘,最大焊接点密度为12个/cm~2,由此可见焊接的可靠性对整机的正常工作是至关重要的,而焊接技术是重要的 I. Overview I plant in 1985 from Japan’s Sanyo Electric Company introduced a secondary welding equipment for the automatic movement of the TV plate movement. The movement plate is the heart of the TV sail, it is complicated circuit, size is limited, so the solder joint is small, the solder joint density is big. Take the 46cm color television set produced by our factory as an example, the pad size is about φ2.5mm, and the maximum welding point density is 12 pieces / cm ~ 2. Therefore, the reliability of the welding is related to the normal work of the whole machine Important, while welding techniques are important
