Efficient use of no-clean solder flux
Dec 08, 2022
12-08
2022
What is the difference between no-clean solder flux and cleaning solder flux
1. No-clean solder flux means that the board surface is relatively clean after solder flux soldering, and the board surface is relatively clean when the requirements are not high or under normal circumstances. However, in special cases, it is still necessary to clean the board surface.
What are the rigid requirements for solder paste in surface mount and assembly processes?
Dec 08, 2022

2022
With the application of reflow soldering technology, solder paste has become an important process material in surface mount technology (SMT). In the reflow soldering of surface mount components, solder paste is used to implement the leads or terminals of surface mount components. The connection of the solder pad on the board.
Tin alloy lead-free solder inspection
Dec 07, 2022
12-07
2022
Tin alloys are a lead-free soldering option, however, soldering can exhibit the appearance of "whiskers" - small bumps of metal that protrude beyond the solder joint or pad. This kind of whisker can grow very long, so that the current of the two welding areas is too large, a short circuit occurs, and the equipment malfunctions. This problem can be easily found using tin alloys in-circuit test, but it can take time for tin whiskers to grow, and it can be a long-standing reliability problem.
Detection method of lead-free tin bar
Dec 07, 2022

2022
Lead-free solder bars have a high melting point and can damage components or assemblies. According to the concept of lead-free soldering, the melting point temperature of SnAgCu is increased from 183°C to nearly 217°C, and the peak temperature is as high as 260°C. After a long period of preheating, the high temperature can be properly reduced. Trim temperatures are also affected, with some components reaching up to 280°C. Components used at such higher temperatures must undergo qualification certification, and uncertified components need to be assembled manually.
Tin bar welding technical requirements
Dec 06, 2022
12-06
2022
Tin bars weld high-quality printed boards, the most important thing is the setting of technical parameters, and how to make these technical parameters reach the best value. Make the solder joints free from missing soldering, virtual soldering, bridging, pinholes, air bubbles, cracks, hanging tin, and sharpening. The setting parameters should be tested and analyzed to find out a set of optimal parameters and record them.
What are the characteristics of the change in the heating process of solder paste soldering?

What are the characteristics of solder paste changes during solder paste soldering heating? The following solder paste manufacturers will talk about it for you:
When the solder paste is always in a heated state, its reflow can be divided into five processes:
In the first step, apply up to the required viscosity and performance of the screen printing material. The solvent gradually begins to evaporate, and the surface temperature must be slow (about 3°C per second to limit boiling and splashing to prevent the formation of small tin beads.
What role does rosin play in solder?
Dec 05, 2022
12-05
2022
Everyone knows that in the process of solder wire, rosin is just a kind of flux. There are several aspects such as oil pollution on the surface of the material, increasing the welding area, and preventing re-oxidation, so what role will rosin play in the process?
How to use tin wire to weld aluminum components
Dec 05, 2022

2022
Aluminum can be soldered with an electric soldering iron and tin wire. The key is to use a special flux to remove the aluminum oxide layer. Aluminum conducts heat faster, so use a high-power soldering iron.
Summary of advantages and disadvantages of low temperature lead-free solder paste
Dec 02, 2022
12-02
2022
In the soldering industry, each manufacturer’s solder paste formula is different, the production process is different, and the types will also have certain differences. According to the melting point of lead-free solder paste, it can be divided into low-temperature solder paste, medium-temperature solder paste and high-temperature solder paste. As the name suggests, solder paste is a solder paste with a low melting point temperature.
What is the difference between flux, flux paste and solder paste?
Dec 02, 2022

2022
In the electronics industry, I believe everyone has heard of electronic solder such as flux, solder paste, and solder paste. Flux, solder paste, and solder paste are all used in soldering processes, and there are still obvious differences between them. Yes, let's introduce it in detail:
