Product Introduction
singway's solder bars are made from high quality Yunnan high purity tin gold with a range of outstanding features that are particularly suitable for high quality welding methods such as wave soldering, selective wave soldering and manual welding:
The first high purity tin gold material: We choose high purity Yunnan tin gold material to ensure the raw material quality of the solder bar, reduce the content of oxidation and impurities, and provide high quality welding performance.
The second vacuum deoxidation treatment: the solder strip is subjected to vacuum deoxidation treatment to effectively reduce the oxygen content, ensure that unnecessary oxidation reactions do not occur during welding, and improve the welding quality.
Third uniform casting: We use a uniform casting process to ensure the uniformity and consistency of the solder strip, so that the temperature distribution in the welding process is uniform, and improve the quality and stability of the solder joint.
Fourth for high quality welding: These solder bars are especially suitable for applications requiring high quality welding, such as wave soldering, selective wave soldering, etc., to ensure that the solder joint is bright, uniform and strong.
The fifth kind of welding method: not only suitable for wave soldering and selective wave soldering, but also suitable for manual welding, providing flexibility for a variety of welding methods.
Sixth, reliable quality: Through strict quality control and monitoring, our solder bars ensure reliable quality and provide a highly stable material for welding tasks.

Product Features

Increase productivity

Less slag discharge

Short wetting time

Fast melting speed

Easily solderable

Strong antioxidant capacity

High reliability of solder joins

Good expansion ability

Under the same process conditions, the chain speed is accelerated from 70cm/min to 90cm/min, the fluidity of the solder is significantly improved, the residence time of the solder is reduced, and the temperature of the tin furnace can be kept at a low level, which not only reduces the generation of tin slag, but also reduces the possibility of precipitation of metal elements such as copper and chromium, and ultimately improves the quality and efficiency of welding. This change significantly optimizes the welding process, reduces energy consumption, reduces material loss, improves the cleanliness of the welding environment, and accelerates the production speed, making the production process more economical and efficient.

Hey, let’s talk about high-temp solder wire—you know, the stuff that doesn’t melt when things get hot? Regular solder wires melt too easy, right? Like that common 8812 one, it only handles 250-280°C. But when you’re packaging chips, you gotta bake ’em multiple times at high temps. Conventional lead-
During wave soldering, dip soldering, and other soldering processes, excessive dross on the solder pot surface not only increases solder bar consumption costs but also leads to solder joint inclusions, cold joints, poor soldering quality, and even reduced overall production line efficiency.
