Types of solder commonly used in electronic industry welding
Oct 12, 2022
10-12
2022
(1) Filament solder - usually called solder wire, with rosin flux in the center, called rosin core wire, which is commonly used in manual soldering.
(2) Sheet solder - commonly used in the welding of silicon wafers and other sheet welds.
(3) Ribbon solder - commonly used in automatic assembly production lines, an automatic welding machine is used to punch a section from the ribbon-shaped solder for welding to improve production efficiency.
(4) Solder paste - It is made by mixing solder and flux powder together. It has been widely used in the automatic patch process.
Can solder paste completely replace solder?

2022
Whether solder paste can replace solder, I believe some people will have this question. When it comes to solder paste and solder work, the final result is to weld components firmly, but whether they can be replaced, the specific analysis is as follows :
First of all, solder paste is a paste-like solid that is uniformly mixed with solder alloy powder and flux carrier system in a certain proportion; the viscosity of solder paste has rheological properties,
Correct use of solder wire

2022
Correct use of solder wire can effectively improve the efficiency of soldering, so how to operate to meet its standards? We generally think that mastering the correct and skilled solder wire welding operation method is the first and most important step rate. Summarizing a large amount of information and years of experience of technical engineers in the solder industry, we have drawn some attention directions and welding standards for the correct use of solder wire:

The role and advantages of high temperature anti-oxidation solder bar
Sep 30, 2022
09-30
2022
The high temperature anti-oxidation solder bar is specially manufactured for electronic manufacturers whose solder furnace temperature is 400°C-500°C. Provide building templates for electronic components containing enameled wires, and tinning for coolers (such as transformers, inductors, coils, relays, degaussing coils, etc.).
How to choose solder paste correctly

The main difference between high-temperature solder paste and low-temperature solder paste is that the temperature of some chips cannot be high when passing through the furnace, and bubbles will form when the temperature is high, but the low-temperature solder paste may cause problems with some vibration pins after the temperature is generated (higher). , High temperature solder paste is generally used in SMT components with large heat generation. Some components generate large heat and can withstand high temperature, while low temperature solder paste contains bismuth element, which is relatively brittle. If the components need to move or vibrate, it is not recommended to use Low temperature solder paste.
What is the difference between solder paste and tin bar?

Solder paste and tin bar products are both solder products and are widely used in the electronics industry. So what is the difference between solder paste and tin bar? The following is a summary of the differences between solder paste and solder wire by double Chile solder manufacturers:
What are the advantages of low temperature tin wire?
Sep 28, 2022

2022
What is the difference between low temperature tin wire and usual tin wire? Why use low temperature tin wire, and what advantages does it have over other tin wires?
This has to start from the alloy composition of the low-temperature tin wire. The low-temperature tin wire is a tin wire with Sn and Bi as the main alloy components. The proportion of this tin wire is 42% for Sn and 58% for Bi. The lead-tin wire we usually use is composed of tin-lead alloy, and the lead-free tin wire is basically composed of three metals: tin, silver, and copper. In contrast, bismuth is the focus of low-temperature tin wires.
What sign of solder wire is lead-free environmental protection?
Sep 28, 2022
09-28
2022
Solder wire is divided into lead solder wire and lead-free solder wire, so how to distinguish lead and lead-free solder wire? In fact, it can be distinguished from the mark of the tin wire.
The wire diameter, rosin content, and weight are generally written on the label of the solder wire, which are all very easy to distinguish. The wire diameter is marked with mm, such as 0.8mm, which means that the wire diameter is 0.8mm.
The relationship between solder wire and fuse?
Sep 27, 2022
09-27
2022
In the solder industry, the questions asked by customers are really ever-changing. One customer asked whether solder wire and fuse can be mixed. What is the relationship between the two? Is there any difference? We also searched for this question. Here are some relevant information to share with you:
The composition of leaded solder wire is an alloy of tin and lead. The proportion of tin and lead is different, and the melting point of the solder wire is also different; the melting point of lead-free solder wire and the temperature required for welding are also different.
