In today's society, the pace of life is getting faster and faster, and the requirements for products are also getting higher and higher. Everyone likes to carry things conveniently, just like headphones. In the past, there were only wired headphones, but nowadays, such products are relatively fewer, and Bluetooth headphones are chosen more often. Facing the current competitive market, it is very fierce. And at this time, Nowadays, many people have many demands. Now, JJY Solder Paste Manufacturer will explain to you how to choose solder paste for headphones during the soldering process?

I. Selection of Welding Process

In terms of soldering technology, most factories nowadays use manual soldering. Traditional manual soldering is highly flexible and less likely to cause damage to headphones, but the soldering speed is relatively slow. Some highly automated devices will use automatic soldering machines for soldering. This method consumes a lot of materials, has inaccurate soldering accuracy, and is prone to damaging the earphone casing. However, the soldering speed has been greatly improved, being about five times that of manual soldering. In addition, there is laser soldering, which has become popular in recent years.

Advantages of laser soldering:

1It is suitable for soldering small and precision parts and places where the soldered parts are sensitive to temperature.

2Fast heating speed, precise positioning, and can be used in0.2Completed within seconds.

3As long as the surface of the workpiece is kept clean, there is no need to use flux, eliminating the need for secondary cleaning and ensuring the service life of the workpiece to the greatest extent.

4Non-contact welding, no generation of static electricity.

5The yield rate of solder is higher than that of ordinary automatic soldering machines.

6.Equipped with a visual positioning system, it is suitable for assembly line production.

Ii. Selection of Solder Paste

The first thing we need to consider is safety. Since headphones come into close contact with the human body when in use and are very close to the head, it is necessary to choose solder paste that poses less harm to the human body. Secondly, sound quality is a major criterion for consumers to judge the quality of headphones, so we need solder paste that can ensure the sound quality does not deteriorate. Finally, what we need to consider is the residual problem during welding.TWSThe components used in headphones are relatively delicate and difficult to clean, so the residue after welding must be minimal.

According to the requirements listed above, the most suitable one isLead-free silver-containing solder pasteThat's it. Lead-free silver-containing solder paste has low environmental toxicity and leaves little residue after soldering, which can meet the requirements of human safety and no need for cleaning during soldering. Moreover, lead-free silver-containing solder paste has good wettability, does not dry easily, has stable effect, strong electrical conductivity, good performance, and can effectively ensure that the sound quality does not deteriorate.
