What are the phenomena that occur when the solder bar is welded?
Sep 14, 2022
09-14
2022
During the welding process of the tin bar, some unexpected situations will occur, resulting in poor welding. What is the reason for the tin bar to appear in these situations?
1. The flux and the bottom surface are in poor contact; the angle between the bottom plate and the liquid surface is improper.
Are tin wires and soldering wires the same, and what are their functions?
Sep 13, 2022

2022
Solder wire is a very important material in the electronic soldering industry, used for manual soldering of products and automatic soldering with the aid of machines. The tin wire is composed of two parts: tin alloy and flux. The alloy components are divided into tin-lead, tin-copper, etc., and the flux is evenly poured into the middle part of the tin alloy. The common classifications of tin wire are lead-free tin wire and leaded tin wire (also called lead-free solder wire and leaded tin wire); tin wires with different compositions have different melting points and corresponding uses.
Poor analysis of solder joint position bridges when soldering with solder paste

2022
There are various reasons for the short circuit between the solder joints of the circuit board formed during the soldering process with solder paste, which can be mainly divided into three categories: one is the reason of the solder paste itself; the other is the reason of the incoming circuit board ; The third is the influence of welding process. Solder paste manufacturers can analyze the reasons for these defects one by one:
How to use eco-friendly tin bars
Sep 09, 2022

2022
With the increasing awareness of environmental protection, the solder in the electronic manufacturing industry is also required to be environmentally friendly. Therefore, environmentally friendly tin bars have begun to replace traditional leaded tin bars. The price of environmentally friendly tin bars is higher. From the perspective of cost saving, waste environmentally friendly tin bars need to be recycled.
Soldering process related materials and common sense

1 Definition of solder: the use of heating tools (electric ferrochrome) to firmly join two or more point metal conductors to achieve the purpose of conducting electricity.
make process.
2 Common sense of solder: There are generally two types of solder commonly used in toy assembly:
A. Tin bar: It is used on the wave crest passing tin machine specially used for electronic pulling, which will not be introduced here.
B. Tin wire:
a Composition: 60% tin, 40% lead, the hollow part of the tin wire contains flux.
b. Features: The melting temperature of the tin wire is above 190 C, and the conductivity is good.
Solder Wire Solder Wire Solder Bar Tin Bar Tin Wire Various Uses
Sep 08, 2022

2022
The production and maintenance process of electronics, hardware, clocks, toys, accessories and other industries are inseparable from soldering, so lead-free tin bar soldering materials are indispensable in these jobs. The melting point of solder varies with the ratio of tin to lead, and the melting point of tin-lead alloys is lower than that of any other alloy. High-quality solder has a tin-lead ratio of 63% tin and 37% lead. The melting point of this proportion of solder is 183°C. Some poor-quality solders have higher melting points, and the solder joints are rough and slag-like after solidification, which is due to the high lead content in the solder.
Solder paste quality inspection steps

1. For solder powder detection, the particle size of tin powder can be measured with a high magnification microscope to check the distribution of tin powder particles. It is relatively high, which proves that the quality of this solder paste solder powder is relatively good, and it will not affect the quality of SMD printing on the stencil.
The reason for the large amount of tin slag in the tin bar?

2022
There are many reasons for the generation of tin dross, involving product quality, operation methods and maintenance methods of machinery and equipment, welding materials, etc. It is often encountered that many factories do not care about the height of the tin surface. Some tin bar factories with the same specifications and series use only about 5KG/8 hours of tin dross, while others use more than 10 kg/8 hours of tin dross.
What is tin bar? The role of tin bar?
Sep 07, 2022

2022
Tin bar is a solder product. There are two types of tin bars: leaded tin bars and lead-free tin bars, both of which are used for circuit board soldering. Made of pure tin, good wetting and fluidity, easy to tinplate. The solder joints are bright and full, and there will be no welding and other undesirable phenomena. Add enough antioxidant elements, strong antioxidant ability. Made of pure tin, reducing tin dross and reducing unnecessary waste.
How many degrees should the lead-free tin bars be set properly during use?
Sep 06, 2022

2022
Generally speaking, we should set the appropriate degree during use. I believe that many technical experts will discuss this issue. The general temperature of lead-free solder bar welding is set to 280 plus or minus 10 degrees, because there is no preheating for manual dip soldering. , so the temperature setting is generally higher.
