The welding working principle of precision spot welding heads

1.Stress connection: When precision spot welding head is welded at room temperature, pure solder is a plastic self-annealing alloy, it can absorb stress under the condition of work hardening or fatigue and damage due to stress cycling. The unique function of this precision spot welding head soldering enables it to connect materials with different thermal expansion coefficients,rigidity and strength under the condition that some typical requirements of mechanical assembly accessories are not proposed for planning. Fox example, the planning of printed circuit boards violates all structural planning criteria related to stress convergence, material strength, load distribution and vibration resistance. If there is no soft soldering connection method and its stress connection ability, it is impossible to have printed circuit boards well known today. If other stress yield welding methods are selected, such as brazing or other welding methods, it may cause the damage of the laminate, the drop of the line strip and the damage of the glass-metal seal of the board-on-board equipment.

2.Reliability: Because soft soldering can be welded at a lower temperature, plastic and welded components usually do not deform and deteriorate due to heat.

3.Economical: Because the equipment used for soft soldering of precision spot welding head is simple, the material is cheap and the soldering process is controllable, so the soldering method is particularly economical. In the near future, as long as we still use wires, semiconductor equipment ans insulation material and make circuits based on the principles of electric pulse ans magnetic pulse, the soft soldering of precision spot welding head will be an essential technical means.
