Types of lead-free solder paste
Jan 06, 2023
01-06
2023
Lead-free solder paste is one of the more common auxiliary materials for soldering in the electronics industry. Nowadays, with the development of the times, it will be used in many of our industries. Lead-free solder paste is divided into several types, because there are many types and specifications of solder paste, and the products for soldering are also different, of course, the price is also different. The following solder paste manufacturers will talk about it for everyone:
How to solve the problem of air bubbles in lead-free solder paste solder joints
Jan 05, 2023
01-05
2023
When using lead-free solder paste for soldering, some air bubbles will appear in the solder joints from time to time, which not only endangers the stability of the solder joints, but also increases the probability of invalid components. Most electronic component manufacturers will use it. Solder paste manufacturers Let me explain to you:
Solder bars and fluxes make a perfect match
Jan 05, 2023

2023
Poor soldering of electronic products with tin bars can cause problems with circuit boards. Let's introduce tin bar + flux to ensure excellent solder joints.
Perfect solder joints: use the right flux, there are many types of flux, there are lead-free flux and lead flux, which one you use when soldering is very important, choose the right flux for the excellent quality of solder joints Role is crucial.
Active tin wire knowledge

2023
Solder wire is one of the indispensable electronic accessories for welding and repair welding in the electronics industry. According to the production process, it can be divided into two types, one is solid core, the other is hollow core and rosin. At present, the tin wire with hollow core and rosin It can be used for direct welding during welding, which is convenient and widely used, and the efficiency is much higher. Recently, some people have asked what is active solder wire and what are its advantages?
The alloy composition of leaded solder paste and lead-free solder paste is different
Jan 04, 2023
01-04
2023
The components of lead-free solder paste are: Sn, Ag, Cu, Bi, and the main components of leaded solder paste are: Sn, PB. We cannot directly distinguish this alloy with the naked eye. It needs to be detected by a spectral analysis instrument. detection.
Classification of tin bars and reuse of solder bars

1. Classification of tin bars
Tin bars are classified according to their composition and can be divided into leaded tin bars and lead-free tin bars.
At present, the commonly used lead-free tin bars are: tin-copper lead-free tin bars (Sn99. /Pb40 etc.)
What are the basic contents of solder paste in process research?
Jan 03, 2023

2023
At present, it is the most popular technology in the electronic assembly industry. With the continuous improvement of circuit assembly density, the wide application of reflow soldering technology, and the concept of "green assembly", the demand for solder paste in the SMT industry continues to increase. Nowadays, it has become one of the indispensable raw materials, and the problems that everyone should pay attention to in the process of use are not known.
Rosin usage specification for lead-free solder bar
Dec 30, 2022

2022
Rosin is a common additive in lead-free solder bars, so rosin will not cause electrical conductivity. It is an insulator itself, but the additive content of lead-free solder bars contains rosin but there are other active substances. Lead-free solder bars Excessive metering of some active substances may cause leakage.
How to Improve Solder Paste Printing Process

2022
Although the SMT process is currently a very mature manufacturing process, there are still many aspects that can be innovated to improve the advanced nature of the process. For solder paste research and development companies, producing a solder paste material that can print small gaps less than 0.4mm is one of the challenges currently facing; for users, before choosing a suitable solder paste
Tin wire structure
Dec 29, 2022

2022
The skill of tin wire welding is a proficient process. The speed of soldering mainly depends on the selection of solder wire. The speed of tinning on high-quality solder wire is fast. For the ordinary soldering structure of PCB, it is usually required that the size of the solder joint between the solder wire and the PCB should be Select the solder wire with high tensile strength and high activity for the alloy structure of the solder joints of the PCB board.
