Welding method of multifunctional hot pressure welding machine

Abstract

The invention discloses a welding method of a multifunctional hot pressure welding machine. The method comprises following steps: firstly, a circuit board to be welded is placed on a work table of a base surface, and through a positioning block on the work table, determining of the designated welding wire position is carried out; a power source of the hot pressure welding machine is turned on, and through a control keyboard on a control panel on the surface of a control host, a hydraulic drive box is controlled to drive a lifting rod to move downwards. The welding method of the multifunctional hot pressure welding machine has the beneficial effects that a temperature feedback control loop composed of a temperature detector, the control host and a heater can automatically control the pressure head to be heated to the reserved temperature value, the circuit board damage caused by the too high pressure head temperature and the influence of the too low temperature on the welding effect are avoided, and the good manufacturability of the hot pressure welding machine is ensured, and practicability is good.

Description

technical field [0001] The invention relates to the field of hot-press welding machines, in particular to a multifunctional hot-press welding machine welding method. Background technique [0002] 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. In the link, hot-press welding often needs to use a hot-press welding machine during operation. However, the traditional hot-press welding machine cannot perform constant temperature control heating on the pressure head when it is working. Since the heating temperature of the pressure head cannot be accurately controlled, if overheating will Burning the circuit board to be welded, if the temperature is too low, it will directly affect the welding ...

[0002] 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. In the link, hot-press welding often needs to use a hot-press welding machine during operation. However, the traditional hot-press welding machine cannot perform constant temperature control heating on the pressure head when it is working. Since the heating temperature of the pressure head cannot be accurately controlled, if overheating will Burn the circuit board to be welded. If the temperature is too low, it will directly affect the welding effect. In view of the above situation, a new welding method of hot press welding machine can be designed to solve the above problems.
