Laser welding machine laser welding processing technics on capacitor case

Capacitor is one of the most widely used electronic components in electronic devices. It is widely used in the circuit for passing alternating current and stopping direct current, coupling, bypassing, filtering, resonance loop, energy conversion, and control etc. With the rapid development of electronic information technology, the upgrade speed of digital electronic products is getting faster and faster. The production and sales of consumer electronic products, mainly flat-panel TV (LCD and PDP), notebook computer, digital camera and so on, continue to grow, driving the growth of capacitor industry.

As the demand for capacitors increases, its quality requirements are also becoming higher and higher. According to the analysis of the market, the processing technics of capacitors often determine the quality of the capacitors. Durable capacitor components are generally processed by fine welding technics. Today many capacitors adopt soldering, which is also a common traditional soldering process.

However, the components processed by soldering are not perfect and many flaws occur. When soldering, it will produce a pungent smell, which is harmful to human body. Therefore, we recommend not use the soldering method. Laser welding will be much better to process the capacitors. Nowadays, there is a special equipment for capacitor welding in the welding market, that is continuous Laser welding machine.

The continuous laser welding machine uses a high-energy laser to locally heat the material in small area. The energy of the laser diffuses into the interior of the material through heat conduction, and the material is melted to form a specific molten pool. Laser welding is mainly for the welding of thin-walled materials and precision parts, it can implement spot welding, butt welding, stitch welding, sealing welding, and the like.

The capacitor laser welding machine developed by Shenzhen Sunlaser adopts non-contact welding. The operation process does not require pressure, it has small weld seam and heat affected zone, little deformation, fast welding speed, smooth and beautiful weld seam.
