Lead Free PCB Assembly
Lead-free PCB assembly is the process of producing and assembling printed circuit boards (PCBs) with lead-free components and solders. Lead is a toxic metal that has long been used in the production of electronics, but it is now being phased out due to environmental and health concerns.
Committed to Manufacturing Solutions
RoHS PCBs and advanced circuits. As a lead-free solder finish, Advanced Circuits employs a Tin Copper alloy. It's Nihon Superior's SN100CL, a solder that's been around for a while in Asia. It is composed of 99.3% tin, 0.06% copper, and some proprietary elements such as nickel.

Testing Procedures
The process of producing and assembling printed circuit boards (PCBs) with lead-free components and solders is known as lead-free PCB assembly. Lead is a toxic metal that has long been used in electronic manufacturing, but it is being phased out due to environmental and health concerns.
The use of lead-free components and solders is used in lead-free PCB assembly. Alternatives to lead-based solders that can be used in lead-free assembly include tin-silver-copper alloys, tin-copper alloys, and tin-bismuth alloys. Due to their higher melting point than lead-based solders, these alloys can be more difficult to work with and may require specialized equipment and techniques.
As more companies and governments implement regulations to reduce the use of lead in electronics, lead-free PCB assembly is becoming more common. Adopting lead-free assembly can help to protect the environment while also lowering the risk of health problems associated with lead exposure.
