Laser soldering machine how to choose the solder wire welding

 Laser tin welder welding is suitable for a variety of industrial fields, for different sizes and shapes of products, and according to the product, characteristics can provide a variety of welding methods. Take tin wire laser welding as an example, laser wire feeding welding process, laser welding head, or product driven by the 3-axis platform, to complete the process of single-point wire feeding welding or moving wire feeding welding. Realize the automatic operation of the wire feeding and welding process. With a point/ring/ellipse laser; can be adjusted through the focal length of the size of the weld joint; can be quickly programmed to switch products and other characteristics.

Laser soldering with different wires

1. Rosin-type solder wire

 

Suitable for welding of repair and related components in the electronics industry. The residue after soldering has high impedance, no leakage, and can pass the high voltage test. It is the most commonly used tin wire in the electronics industry.

 

2. No-clean solder wire

 

Ideal for refinishing PCBs that require less soldering residue, high insulation resistance, and clean surfaces.

 

3. Nickel-plated solder wire

 

Suitable for soldering hard materials such as nickel materials, nickel-plated surface components, wires, terminals, sockets, lamp holders, etc.

 

4. Welding aluminum wire

 

Suitable for soldering aluminum materials. The flux is non-rosin type, and soldering is firm and reliable with very good results. The residue after soldering can be washed with water.

 


5. Stainless steel tin

 

Suitable for soldering stainless steel materials. The flux is non-rosin type, the soldering is firm and reliable, the effect is very good, and the residue after joining can be washed with water.


6. Solid core solder wire

 

Flux-free, suitable for special applications such as fuses and metal pipe fittings.

 

7. Specialized soldering wire for cell phone drag soldering

 

Suitable for multi-lead fillet welding of cell phone accessories, IC, flat cable, connecting wires, etc. The welding effect is very good, and it can be used for small-spacing soldering at one time.

 

The temperature management of laser welding is very important, and MRJ laser solder wire equipment has a temperature regulation control system. Depending on the solder wire or solder wire used, it is very important to select the most appropriate temperature setting through the specialized soldering operation software. When using lead-free solder for the soldering operation, it is usually desirable to set the temperature of the laser solder wire below 350 degrees to 370 degrees due to the heat resistance of the parts and the consideration of safe operation.

History of Lasers

Image
  Lasers have been hailed as one of the great inventions of the twentieth century, following nuclear power, computers, and semiconductors, and have brought about a great technological breakthrough for mankind. The laser radiation produced by lasers is famous for being the "fastest blade", the "most accurate ruler" and the "brightest light". Nowadays, laser technology plays an important role in many fields such as medicine, the military industry, communications, and so on.   The birth of the laser is the result of the tireless efforts and arduous exploration of many scientists.   In 1917, Albert Einstein proposed the concept of "stimulated radiation", which laid the cornerstone for the theoretical foundation of lasers.   Although the theory of lasers had already been proposed at that time, the actual preparation of lasers was quite challenging. By the 1950s, with the progress of photon and microwave technology, the manufacture of an oscillator cap...

Automated laser welding improves MDM yields

Image
Hiring and training skilled personnel is not only costly, but in today's labor market, it is becoming increasingly difficult for companies to find and retain this talent. Automated laser welding systems dramatically reduce the need for skilled personnel. For example, once an engineer or technician has specified and stored all aspects of a welding application using the machine software, the operator can safely initiate the welding process with limited access to functions through the GUI.   Avoiding subjective judgment on the operator's part, combined with the use of in-situ vision, process monitoring, laser monitoring, and post-process validation features, provides consistent production, increased yields, and reduced scrap. Whenever there is any deviation from the specified limits in the process, the machine makes the necessary adjustments or stops the process and alerts the operator. This is clearly a benefit for any application. It would be especially beneficial when welding p...
