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.

The Printed Circuit Boards were flawlessly assembled. Mis Wang, the WINOW engineer in charge of our project, organized the parts flawlessly. She asked all of the pertinent questions to ensure a successful outcome. We had a very pleasant and productive working relationship with her, and we hope to work with her on future projects again.
This board is required to charge the lipo batteries on my robotic platform (rover). I ordered this item for the first time and was pleased with the excellent communication throughout the ordering process, manufacturing progress, and delivery tracking. It was shipped quickly and arrived on time.
The boards arrived yesterday, and assembly has begun. Outstanding solder wetting, crisp line definition, and drill holes centered on the via lands.
Please convey my gratitude to everyone who created such wonderful boards.
