Spot welding head design principles: different welding materials, different welding point requirements, different welding energy, and different spot welding head designs required. General spot welding heads are divided into three parts, namely the power connection part and the transition part As with the discharge part, different designs have different effects on connection, gathering and discharge, which will lead to different welding effects and service life. Generally speaking, a good discharge effect means a good welding strength and a low welding voltage. Under the same parameters, the service life of the corresponding spot welding head will be reduced.

The spot welding head is generally used in spot resistance welding equipment, and it is in direct contact with the object to be welded, and is a device that directly supplies current and pressure to the object to be welded. The difference between a spot welding head and a soldering iron head is that spot welding is actually a type of electric welding. The object to be welded is dissolved in another object to be touched by the instantaneous high temperature of the current, thereby welding them together. The electric soldering iron is a manual soldering tool, and the soldering iron can be well welded by heating the tip of the soldering iron to above 300℃. Precision welding equipment: electronic spot welding machine designed for welding metal wires or metal sheets with a diameter or thickness of more than 0.4mm. It is suitable for tin-free welding between the PIN pins and wires of various connector plugs. 1.Welding equipment with AC power supply and large pressure adjustment. Fine Pulse Heat Press: Provides precise temperature and pressure control with precise positioning and adjustment equipment. Therefore, it can be used for soldering gold fingers such as FFC, TCP, FPC and circuit boards. 2.Pulse heat press: It can provide accurate control of temperature and pressure. It can be used as a high-end soldering iron, equipped with a certain automatic welding channel, which is more efficient. It is suitable for welding between various connector plugs and connecting wires. 3.Automatic welding equipment: It can supply automatic welding channels, and perform sequential welding according to the preset welding procedures, without manual intervention. Improve production efficiency.

1.When the new evaporation boat is used, the voltage is gradually increased by screen operation to control the time, each time the voltage is increased for 5 minutes, and them it is increased again( for example 7V-8V-9V)or started according to the program set by the aluminum plating machine. Gradually boost and heat the evaporation boat process anneal to release internal pressure. At the same time, the gas absorbed inside the boat material is also released. Aluminum wire combines with the evaporation boat, and it takes about 20 minutes to wet it. Wetting too fast will reduce the stability of the evaporation gas and greatly shorten the service life of the evaporation boat.
