With the continuous upgrading of global environmental protection regulations, lead-free soldering has become the mainstream process in the SMT and PCBA manufacturing industry. It has replaced traditional tin-lead materials and is widely used in consumer electronics, industrial control, smart home and automotive electronics.
Lead-free soldering adopts lead-free environmental solder alloy, solder paste and flux, cooperating with professional reflow temperature profile to complete soldering. It has obvious advantages compared with traditional tin-lead technology:
- Environmental FriendlyComply with RoHS standards, no heavy metal pollution, and meet market access requirements for Europe, America and other regions.
- Higher Solder Joint ReliabilityLead-free solder has denser structure, better resistance to thermal cycling and vibration. It is not easy to crack or fail after long-term operation.
- Excellent High Temperature ResistanceSuitable for automotive and industrial high-temperature working environment, maintaining stable performance without softening and deformation.
- Suitable for Miniature ComponentsFor 0201 and 01005 tiny components, lead-free solder shows uniform wettability and reduces defects such as bridging, solder beads and voids.
Lead-free soldering requires higher melting point and reflow temperature. It puts forward stricter requirements on PCB heat resistance, solder paste selection and process parameter optimization.
Globalwell fully adopts RoHS lead-free production standards. With professional process optimization and material control, we provide stable and high-quality SMT processing for export and high-precision electronic products.
