What is the difference between solder and tin?
Jan 12, 2023
01-12
2023
Solder is an important raw material for connecting electronic components when soldering lines, including tin wire, tin ball, tin bar, etc. Applied to all kinds of electronic soldering, suitable for manual soldering, wave soldering, reflow soldering and other processes. The wire solder used in standard soldering operations is called rosin cored solder wire or wire. Flux is added to the solder. This flux is composed of rosin and a small amount of activator.
How to choose solder paste
Jan 12, 2023
01-12
2023
When we choose solder paste, we must first understand the basic characteristics of the components themselves, such as how high the temperature is, what is the material of the components, and what is the process of the components, etc.
Lead-free environmentally friendly tin bars play an important role in work
Jan 11, 2023
01-11
2023
Lead-free environmentally friendly tin bars play a very important role in soldering work. Solder bars made of different alloy components also have different properties and uses.
(1) Pay attention to the height of the liquid level in the solder furnace, the tin inside should not be too much or too little, and the technicians should pay attention to reasonable control;
How to maintain the solder paste when using it?
Jan 11, 2023
01-11
2023
We all know that solder paste is a viscous paste-like object composed of tin and other metal substances, fluxes, and additives. Its main function is to solder components to the corresponding positions on the PCB board. How to maintain the solder paste during use?
Why do soldering iron lead-free soldering process choose tin-copper lead-free tin wire?
Jan 10, 2023
01-10
2023
There are many kinds of lead-free tin wires that can be used for lead-free soldering with soldering irons, such as tin-copper lead-free tin wires, 3.0 silver lead-free tin wires (305), 0.3 silver lead-free tin wires (0307), etc. Which tin wire to choose? Wire is determined by many factors, such as: the requirements of the soldered product, precision, welding effect, cost control, etc., but today many electronics manufacturers choose tin-copper lead-free tin wire. The reasons are summarized as follows:
Tin Bar Soldering Guidelines and Precautions
Jan 10, 2023
01-10
2023
1. Working temperature:
Sn63/Pb37 lead-tin bar suggested working temperature: 255±10℃.
Suggested operating temperature for lead-free tin bars: 265±10°C.
2. Removal of scum in wave soldering
What are the industrial uses of solder paste?
Jan 09, 2023
01-09
2023
The solder paste itself is also a viscous shape that is uniformly combined with uniform solder alloy powder and reliable flux, and can form an alloy material connection during soldering. This substance is very suitable for the safe and reliable welding of automatic production of surface mount. It is a high-tech product of the modern electronics industry. Let's discuss it together with the following solder paste manufacturers:
What should I do if there is a sharp and continuous welding during tin wire welding
Jan 09, 2023
01-09
2023
Why does the tin wire have the phenomenon of sharp and continuous welding? In many cases, it is because there is moisture in the through hole of the PCB board. When soldering, the moisture is heated and turned into water vapor. Regular tin balls.
How to quantify the impact of solder paste voiding on solder joint performance?
Jan 06, 2023
01-06
2023
Voiding is a common problem when soldering with lead-free solder paste. Spacing between grains of lead-free solder paste can also cause voids. In addition, due to the inconsistent diffusion rate of metal elements, vacancies are usually left in the intermetallic compound body, and the vacancies will form cavities after continuous accumulation. The presence of voids results in compromised electrical and thermal properties.
The use and characteristics of lead-free solder bar and solder bar
