Thermal compression welding head pressure-buffering tin soldering device and tin soldering technology thereof

Abstract

The invention discloses a thermal compression welding head pressure-buffering tin soldering device and a tin soldering technology of the thermal compression welding head pressure-buffering tin soldering device. The device comprises a box body and a machine frame installed on the box body. Hydraulic cylinders are installed on the machine frame, the output ends of the hydraulic cylinders are connected with a sliding plate, an installation plate is installed on the sliding plate through an adjusting mechanism, and a welding head is installed on the installation plate through a welding head base. A pressure buffering mechanism is arranged on the machine frame, and a bearing platform mechanism is arranged at the position, located below the welding head, of the top of the box body. According to the device, the hydraulic cylinders push the sliding plate to move downwards, the adjusting mechanism adjusts the position of the welding head, the downward pressure is gradually buffered through the arrangement of the pressure buffering mechanism, the pressure on workpieces in the process of tin soldering operation of the welding head is gradually reduced, the quality and the reliability of welding spots of the workpieces are improved, the different machined workpieces can be conveniently positioned through the arrangement of the bearing platform mechanism, and the tin soldering operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of soldering, in particular to a thermal pressure welding head slow pressure soldering device and a soldering process thereof.

[0003] Thermocompression welding is a welding process that connects flexible circuit boards and rigid circuit boards. As an emerging manufacturing process and an important part of the microelectronic surface assembly technology field, a stable and efficient thermocompression welding process is undoubtedly important to ensure good product quality. Link, the existing hot-press soldering device, the pressure exerted on the workpiece during the working process is to push the welding head down through the hydraulic cylinder, and perform soldering operations on the workpiece. During the downward movement of the welding head, the welding head does not move down
