Laser soldering machine and manual soldering iron soldering difference

Laser soldering machine and manual soldering iron soldering difference

Dec 14, 2022

12-142022

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.

The main factors affecting the welding quality of tin wire are welding current and energization time, electrode pressure and shunt, etc.
  1. Tin wire welding current and energization time
According to the size of tin wire welding current and the length of energization time, spot welding can be divided into two types: hard specification and soft specification.

Tools and operation steps required for tin wire manual soldering

Dec 13, 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.

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;
What is the impact of weather and temperature changes on solder paste?

What is the impact of weather and temperature changes on solder paste?

Dec 12, 2022

The main products in the soldering industry are solder paste, tin wire, and tin bar. The main raw material for soldering is tin. When the weather is low, the crystal form of tin will be changed, making tin brittle. At present, we All electronic products used have minimum and maximum operating temperatures, so tin is no exception. What impact does the change of weather and temperature have on soldering tin? I have collected some information for you to organize as follows:

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.

What are the differences between 3.0 silver and 0.3 silver in lead-free solder paste

Dec 12, 2022

As a necessary material for reflow soldering in the solder industry, solder paste can be divided into lead-free solder paste and leaded solder paste according to environmental protection standards. Among them, there are 3.0 silver and 0.3 silver environmentally friendly high-temperature solder paste in lead-free solder paste, both of which are Silver-containing environmentally friendly lead-free solder paste series products have passed ROHS certification and are used in SMT reflow soldering processes. So what is the difference between the two, the double Chilean solder manufacturers summarize as follows:

When the solder wire is used for welding, the solder meets the high-temperature soldering iron at the pad and melts due to the high temperature. The liquid tin spreads quickly with the help of flux and is firmly connected to the pad. At this time, there may be two situations that lead to the phenomenon of poor tin frying under the welding process. The editor of the following double Chile solder wire manufacturer will introduce the tin beading phenomenon that occurs when the solder wire is used:
