The double-sided green lead-free tin-plated board is made with an environmentally friendly lead-free soldering material formula, strictly complying with international environmental protection standards such as RoHS. It is produced in a green manner without any pollutant emissions. The double-sided circuit design is combined with a uniform and thick tin coating, significantly enhancing the shear strength of the solder joints. It is resistant to high-temperature aging and has excellent vibration resistance performance. It can effectively reduce the risk of false soldering and ensure stable and undamaged signal transmission. It also has the advantages of flexible wiring and controllable cost. It is widely used in scenarios with high requirements for environmental protection and reliability, such as automotive electronics, medical monitoring equipment, 5G communication modules, industrial control PLCs, and high-end instruments and meters. It is the preferred carrier that combines green manufacturing with high-performance requirements.
