How much is the lead-free environmentally friendly tin wire 1.0mm?
Dec 19, 2022
12-19
2022
Lead-free environmentally friendly tin wire is made of high-purity cloud tin, which is suitable for packaging solder and electronic assembly of semiconductors
The research and development and manufacture of solder are bright and full, with good flow and less spatter.
Process characteristics of lead-free environmentally friendly solder wire
Dec 16, 2022
12-16
2022
Lead-free environmentally friendly solder wire uses lead-free solder instead of traditional tin-lead eutectic solder, which makes the process of lead-free environmentally friendly solder wire have significantly different characteristics. First, the temperature of the welding process is significantly increased, and the process window is sharply reduced.
Use of wave soldering lead-free solder bar

Inspiration and Suggestion from Corrosion Failure of PCBA Components to Wave Soldering Lead-free Solder Bars.
Due to the lack of post-soldering cleaning process, the use of no-clean flux in wave soldering lead-free solder bars has the risk of high surface ion content. If there are certain defects in the solder mask or green oil plug holes, under the action of a continuous electric field, the accumulated corrosive ions will gradually penetrate through the solder mask and corrode the copper layer, resulting in a series of defects in lead-free solder products.
Why does the solder paste need to be warmed up before patch soldering?
Dec 15, 2022
12-15
2022
With the development of society, solder paste, as an auxiliary soldering material, has become an unreliable part of many industries, so it is becoming more and more popular in society now, so everyone knows why it is necessary to warm up before patch soldering. Have you ever understood this, the following solder paste manufacturers will explain it to you:
Application analysis of lead-free solder paste in pcb circuit board
Dec 15, 2022

2022
At present, many companies are using lead-free solder paste products and processes, so lead-free environmental protection solder paste is an important part of the lead-free process, and its performance is attracting more and more attention. The following is based on the product development of lead-free ring solder paste, and discusses in depth some problems caused by lead-free processing technology, such as alloy selection, printability, ultra-low temperature reflow, void level, etc.
Solder ball basic production technology

Laser soldering machine and manual soldering iron soldering difference
Dec 14, 2022
12-14
2022
The process of laser soldering machine and manual soldering iron soldering is divided into three basic steps: preheating, heating for providing tin wire and heating for providing solder after forming. Although the basic process of manual iron soldering and laser soldering is the same, the method of providing heating wire is different. Here's a look at the difference:
Manual soldering iron soldering process.
Tools and operation steps required for tin wire manual soldering
Dec 13, 2022

2022
At present, tin wire welding of electronic components mainly adopts tin soldering technology. Soldering technology uses tin-based tin alloy material as solder. The tin wire melts at a certain temperature, and the metal weldment and tin atoms attract, diffuse, and combine with each other to form an infiltrated bonding layer. It seems that the copper platinum of the printed board and the lead wires of the components are very smooth. In fact, their surfaces have many small concave-convex gaps. The molten tin solder diffuses along the surface of the weldment with the help of capillary suction to form solder and solder joints. The infiltration of the components, the components and the printed board are firmly bonded together, and it has good electrical conductivity.
The main components and functions of solder flux

1. Activator: solder flux can effectively remove oxides on the surface layer of PCB copper film pads and soldering parts of parts, and at the same time have the function of reducing the surface tension of tin and lead;
Solder flux introduction
Dec 12, 2022
12-12
2022
There are many types of solder flux, one of which is the dielectric strength, the higher the better, most solder pastes are organic or acidic substances, organic substances are not conductive, acidic substances may be slightly conductive, but after welding on the circuit half , all volatilize, and only organic matter remains, which will not conduct electricity.
