Preparation method and precautions of lead-free high temperature solder paste
Jan 04, 2023
01-04
2023
Process control and production methods when using lead-free solder paste. Nowadays, soldering of electronic products is an important production link. Currently, lead-free solder paste products are used. There are two types of products, low and high temperature, and they are also called lead and lead-free. , each of which is a different production method and control, the following small series of solder paste manufacturers will first introduce the production method of high-temperature solder paste.
What should be paid attention to when soldering tin wire on the base material?
Jan 03, 2023

2023
Tin wire is a kind of welding material. Tin wire is generally used in the electronics industry relatively more. Tin wire plays a very important and significant role in the field of electronics production. It can be said that it is an indispensable material in the processing and production process of the electronics industry. However, what should be paid attention to when the solder is wetting the substrate?
Production characteristics of lead-free solder wire

With the needs of social development, lead-free solder wire is a very popular soldering product. It has become an irreplaceable existence, lead-free environmental protection and practicality are inseparable, and it is also the main reason why many people choose to use lead-free solder. There is also a reason why more people choose to rely on lead-free solder, because this creation is of greater help to many businesses.
Why lead-free solder paste is easy to dry

1. It is said that it is due to the solvent in the formula of the flux in the lead-free solder paste. It is true. If the flux used to produce solder paste is volatile
Of course, the solder paste will dry out slowly during use. However, there are too many factors for the dryness of solder paste, and the dryness of solder paste is due to the instability of the flux system.
Is there any hazard in lead-free tin bar solder?
Dec 30, 2022

2022
Lead-free tin bar solder is more or less toxic, and tin bar solder is divided into lead-free solder and leaded solder. Is lead-free solder toxic? The gas produced when using lead solder wire is toxic Yes, in addition to gases such as rosin oil and zinc chloride, lead vapor will also be produced. But now the tin wire is lead-free. Do not inhale the fumes generated during soldering of lead-free tin bars. Generally, factories will install fume exhaust pipes to reduce harm to the human body. Do a good job of ventilation.
How to use solid core solder wire
Dec 29, 2022

The solid core needs the assistance of flux during welding, because there is no flux in this type of solder wire, hence the name solid core solder wire. The flux used for soldering with solid solder wire is preferably a combination of rosin and a small amount of activator, similar to the type of flux in ordinary solder wire.
How to achieve high-quality results in lead-free solder paste

Along with the generation of SMT, lead-free solder paste also came into being. It combines flux and solder powder, as well as thixotropic agent and surfactant, so as to achieve better soldering effect during the soldering process. Lead-free solder paste is usually used in the soldering process of capacitors, resistors and other components on the surface of PCB.
Judging the sensitivity of environmental protection tin wire

The sensitivity of the environmentally friendly tin wire indicates the ability of the environmentally friendly tin wire to receive weak electromagnetic wave signals. The sensitivity of the environmentally friendly tin wire mainly depends on the performance design of the circuit in the image channel part of the environmentally friendly tin wire.
Solder paste use common problem analysis

Reflow soldering of solder paste is the main board-level interconnection method used in the SMT assembly process. This soldering method combines the required soldering characteristics excellently. These characteristics include ease of processing, wide range of SMT designs Compatibility, high soldering reliability, and low cost; however, when reflow soldering is used as the most important SMT component-level and board-level interconnection method, it is also challenged to further improve soldering performance.
The characteristics of lead-free solder bar and its soldering temperature are intuitive
Dec 27, 2022

2022
For lead-free welding of products exported to Europe, America and other countries, the tools and components used must be lead-free. Lead-free solder bars have light yellow traces, because lead-free generally contains copper metal. Lead-free solder bars are basically lead-free (the EU ROHS standard is less than 1000PPM, and the Japanese standard is less than 500PPM). Lead-free solder bars generally contain tin, silver or copper metal elements.
