What should I do if tin beads appear when solder wire is used?
Dec 12, 2022
12-12
2022
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:
What are the advantages of tin wire reflow soldering machine technology
Dec 09, 2022
12-09
2022
1) When reflow soldering technology is used for soldering, it is not necessary to immerse the printed circuit board in the molten tin wire, but to complete the soldering task by partial heating; therefore, the components to be soldered are less thermally impacted and will not be affected by Overheating causes damage to components.
The principle of reflow soldering and wave soldering of tin bars
Dec 09, 2022
12-09
2022
The difference between reflow soldering of tin bars and wave soldering is that reflow soldering is through SMT boards, while wave soldering is through plug-in boards. Reflow soldering is one of the three main processes in the SMT placement process. Reflow soldering is mainly used to solder PCB circuit boards that have already mounted components, and then cool the solder paste through reflow cooling to solidify the components and pads together.
How to judge whether the solder flux is no-clean
Dec 08, 2022
12-08
2022
Qualified solder flux is not good or bad, and qualified solder flux is only suitable or not. Soldering process, equipment, PCB (circuit board) quality, component quality, solder quality (tin content), operator proficiency, etc. are different, and the selection and requirements for solder flux are also different.
Soldering industry tin bar wave soldering and reflow soldering process
Dec 08, 2022
12-08
2022
Wave soldering refers to the process of spraying the molten solder bar into the solder wave required by the design through the electric pump or electromagnetic pump, so that the printed board pre-installed with components passes through the solder wave to realize the soldering end of the component or the pin and the printed circuit board.
Manual soldering points

2022
The following points are derived from the tin bar soldering mechanism and proved to be generally applicable by practical experience.
1. Master the heating time
Different heating speeds can be used for tin bar soldering, for example, if the shape of the soldering iron tip is bad, we have to extend the time to meet the temperature requirements of the tin bar when soldering large weldments with a small soldering iron. Prolonged heating times are detrimental to electronics assembly in most cases because
What is the difference between automatic welding of tin wire and manual welding?
Dec 07, 2022
12-07
2022
In the solder wire industry, there are two major aspects of solder welding methods, one is automatic welding by machine, and the other is manual welding; the so-called automatic welding by machine refers to the realization of solder wire and components by means of an automatic soldering machine. Welding; Another kind of manual welding is the process of manually feeding tin and manually operating welding components with the help of soldering tools such as soldering iron tips.
Wave soldering operation process and basic tin bar welding process
Dec 06, 2022
12-06
2022
Wave soldering is to make the soldering surface of the plug-in board directly contact with high-temperature liquid tin to achieve the purpose of welding. The high-temperature liquid tin maintains a slope, and the liquid tin is formed by a special device to form a wave-like phenomenon, so it is called "wave soldering", mainly The material is solder bar. At present
Basic principles and basic conditions of tin bar welding
Dec 06, 2022
12-06
2022
Tin bar welding is a welding method that uses its low melting point to heat and melt, then infiltrates and fills the gap at the joint of metal parts. Because the solder is often a tin-based alloy, it is named. Widely used in the electronics industry.
