Description

Double-Sided PCB with Lead-Free HASL

Are you looking for a reliable, cost-effective, and highly durable solution for your electronic projects? Our Double-Sided HASL (Hot Air Solder Leveling) PCBs offer the perfect balance of exceptional solderability, long shelf life, and robust mechanical strength. They are widely utilized in automotive electronics, industrial control systems, smart home appliances, and power supplies.

Key Features & Product Advantages

• Superior Solderability: The Lead-Free HASL surface finish provides a uniform, highly solderable tin coating, ensuring strong and reliable joint connections during both SMT and through-hole assembly processes.

• Double-Sided Circuit Routing: Features top and bottom copper layers connected by plated through-holes (PTH), allowing for higher component density and more complex circuit designs within a compact footprint.

• RoHS Compliant & Eco-Friendly: Manufactured using strict lead-free processes to ensure compliance with global environmental standards, making it smooth for international market clearance.

• Cost-Effective for Volume Production: HASL remains one of the most reliable and budget-friendly surface finishes available, significantly lowering your overall manufacturing costs without sacrificing quality.
