Thermocompression welding head pressure-releasing tin welding device and tin welding technology thereof

Abstract

The invention discloses a thermocompression welding head pressure-releasing tin welding device and a tin welding technology thereof. The thermocompression welding head pressure-releasing tin welding device comprises a workbench, a rack, a machine head, a thermocompression welding head and a pressure regulation hand lever; the rack comprises a first section and a second section; the first section and the second section of the rack are connected perpendicularly; the first section of the rack is connected with the workbench; the second section of the rack is connected with the machine head; the direction of the machine head is perpendicular to the surface of the workbench; the pressure regulation hand lever is arranged at the upper part of the machine head; the thermocompression welding headis arranged at the lower part of the machine head; an equipment switch and an emergency stop switch are arranged on the workbench; the thermocompression welding head comprises a heating sheet, screw locating holes and a connecting sheet; the thermocompression welding head is an alloying thermocompression welding head; and the thermocompression welding head is a single-point, double-point, cross-slot or flat welding head. With the adoption of the thermocompression welding head pressure-releasing tin welding device, welding tin is compressed, and a pressure-releasing process is used, so that thermocompression welding head pressure-releasing tin welding device is simpler in structure and convenient to operate, the appearance of a welded spot is smooth, the forming is good, the quality and thereliability of the welded spot of a workpiece are higher, and the problems of welding tin spattering and solder beading are solved.

Description

technical field [0001] The invention relates to the field of hot-press soldering machines, in particular to the field of automatic hot-press soldering machines. Background technique [0002] As we all know, communication and electronic products require soldering processes in the production process, and most of them require manual simple operations. During manual soldering operations, the soldering speed is relatively slow, which reduces production efficiency. In response to this situation, a fully automatic soldering machine has appeared on the market at present, which can realize automatic welding operations in the X-axis, Y-axis, Z-axis and rotation direction according to the instructions input in advance, instead of manual operation. [0003] The hot-press welding head of the traditional automatic hot-press welding machine basically keeps the pressure on the workpiece during the working process. The solder will be crushed by the welding head at the moment of melting, and ...

AI Technical Summary

Problems solved by technology

[0003] The hot-press welding head of the traditional automatic hot-press welding machine basically keeps the pressure on the workpiece during the working process. The solder will be crushed by the welding head at the moment of melting, and it is easy to make the extruded molten solder Splash out, and the splashed solder will naturally solidify to form tiny tin beads. The tin beads are likely to cause short-circuit faults in the workpiece conductors and reduce the quality and reliability of the workpiece solder joints.
