Lead Free PCB Assembly
Sustainability and environmental responsibility are essential factors for organizations of all sizes in the modern world. By selecting lead-free PCB assembly services for their electronic products, businesses can showcase their dedication to sustainability.
What is lead-free assembly?
Printed circuit boards (PCBs) can be manufactured using leaded or lead-free technology according to user’s needs. Given their advantages for the environment and compliance with the RoHS (Restriction of Hazardous Substances) Directive, which compels businesses to decrease the use of hazardous materials in the production of electronic devices, lead free PCBs are growing in popularity. It is considered necessary for electronics manufacturers to implement lead-free assembly during PCB assembly in addition to adopting lead-free manufacturing technology, which refers to the not use of lead in the soldering process.
Surface mount technology (SMT), which allows components to be placed directly onto the surface of the PCB rather than being inserted through holes, is often used to create lead free PCBA boards. These PCBAs have the potential to outperform conventional PCBAs in terms of reliability, durability, and performance characteristics including electrical conductivity and thermal stability.
Lead-free PCBA services can be tailored to fit the particular requirements of your company and may involve custom PCB design and production, component selection, and the application of advanced manufacturing methods. Your company can showcase dedication to sustainability and environmental responsibility by choosing China lead-free PCB assembly, and it can also produce high-quality, dependable products that adhere to the latest regulatory standards.

Why FS Technology Lead Free PCB Assembly Services?
RoHS-compliant lead-free PCB assembly process
Customized lead-free PCB assembly services can include the design of custom PCBs to meet the specific needs of your business. For electronics companies that do not have design capabilities, the first step in lead-free turnkey assembly is PCB design. This involves creating a detailed schematic and layout that outlines the components, connections, and signals on the PCB. The design process may also involve material (FR4, Rogers, HF) and process (HASL lead-free PCB, gold plated PCB, ENIG), custom shape, size and layout to optimize performance and meet your specific requirements.
Customized lead-free PCB assembly services can include the selection of specific components to meet the needs of your business. This can include selecting components with specific performance characteristics, such as high reliability or low power consumption.
Lead-free circuit board manufacturing
Once the circuit design is complete, the next step is to manufacture lead free PCB. This involves creating the physical PCB using a variety of techniques, such as etching, drilling, and plating. The PCB is typically made from a layer of copper-clad laminate, which is a composite material made up of a layer of copper foil on a substrate of glass-reinforced epoxy.
SMT placement assembly
After the circuit board is fabricated, the next step is to assemble the SMD components. Before entering the SMT high-speed placement machine, FS Technology uses the best lead-free solder paste to ensure the reliability of placement. Then, these components are tiny components that are mounted directly onto the surface of the PCB board using a soldering process. The components are placed onto the PCB using a pick-and-place machine, which positions them accurately on the PCB using a set of robotic arms.
Lead-free reflow soldering
Once the SMT assembly is complete and the SPI inspection equipment confirms that the SMD components are positioned correctly, the PCB will go into a ten-zone reflow oven to be heated to melt the solder paste and bond the components to the PCB. The reflow process is carefully controlled to ensure that the components are properly soldered to the PCB without damaging them.
Testing the quality of turnkey lead free PCBA
According to the needs of customers, various PCB inspections will be run through the entire service process to ensure that they meet the required specifications and standards. This may involve visual detection, functional testing, AOI inspection, and other types of testing to ensure that the PCBA is of high quality and meets the required performance criteria.
Overall, the process of FS Technology’s lead-free PCBA involves designing and PCB fabrication, assembly of SMD and DIP components, reflow/wave soldering, and inspecting and testing the finished PCBA. By working with a manufacturer that offers customized lead-free PCB assembly services, you can ensure that your business gets the specific products and services it needs to meet its unique requirements.
