Reliable Solder Joints It generates strong and firm solder joints, contributing to the longevity of soldered connections. It has long service life. | Good Solderability The silver and copper in this solder brings it a low thermal stress and higher electrical conductivity, ensuring the quality of soldered assemblies. | |
Eco-Friendly Formulation The solder wire doesn't contain lead. It complies with environmental regulations and sustainability initiatives and suitable for projects that require RoH compliant. | Affordable Cost This solder wire contains only 0.3% of silver, making it much lower cost comparing to SAC305 solder wire. This is good for projects that have limited budgets. |
Electronics Manufacturing: Lead-Free Solder Wire Sn99Ag0.3Cu0.7 finds extensive use in creating reliable connections within electronic components, circuit boards, and assemblies. Such as PCBA, microwave ovens, air conditioners, electric kettles, hair dryers, sensors, connectors, switches, etc.
Medical equipment that needs to comply with RoHS regulations and avoid lead contamination, such as pacemakers, defibrillators, ultrasound machines, etc.
Automotive components that require high fatigue resistance and thermal stability, such as ABS systems, engine control units, etc.
