Uses fluorine-based special surfactants. It has strong wetting properties while being compatible with no-rinse applications!
【Overview】 Stainless steel is a base material that can be soldered. The Sn in the solder bonds with the Fe and Ni in the stainless steel to complete the joint. The difficulty of soldering is due to the behavior of the oxide film on stainless steel. While the oxide film on stainless steel serves to prevent rust, it also hinders soldering. During soldering, the oxide film on the stainless surface is removed by the flux, but a new oxide film grows due to heat and oxygen in the air. Therefore, it is necessary to complete the soldering in a short time before the oxide film grows too thick. 【Three Features】 - Strong wettability - Stainless steel can also be soldered - Compatible with no-clean *Test reports are also included in the catalog! *We offer solder with flux for stainless steel, so please contact us!
We will introduce the applications of low melting point solder.
Applications of Low Melting Point Solder Low melting point solder is used for the assembly of heat-sensitive components such as camera modules. Until now, these components have been retrofitted using resin-based solder, but further efforts are being made to lower temperatures and automate processes through the use of low-temperature solder and laser heating. Challenges of Low Melting Point Soldering Low melting point solder requires dedicated flux that matches its melting point, so it cannot be directly applied to what is currently in use. Additionally, since the alloy contains bismuth, caution is needed when using it in areas that require high reliability, such as automotive parts, medical devices, and industrial equipment. Ishikawa Metal's Low Melting Point Solder We already offer a variety of syringe-type solder pastes with proven market performance, including halogen-free syringe-type solder paste, so please contact us for more information. *For more details, feel free to contact us.*
