Product Description

Quick Turnaround Lead-Free PCB Assembly Service CEM1 CEM3 Rigid Flex Printed Circuit Board



Lead-free PCB Assembly Description


Lead-free PCB assembly refers to the process of manufacturing printed circuit boards and assembling electronic components without the use of lead-based materials, in compliance with regulations such as RoHS and REACH. According to these regulations, the lead content of solder paste used for PCB assembly must be within 0.1%.

For a truly lead-free PCB assembly process, the lead-free requirement (Pb < 0.1%) extends throughout the entire EMS manufacturing process. This includes electronic components, PCB copper-clad laminates (CCL), PCB inks, surface finishes, solder paste, enclosures, packaging bags/boxes, and all equipment/devices/jigs used during the fabrication process.

By eliminating lead from the assembly process, lead-free PCBs minimize environmental impact and health risks associated with lead exposure, while still ensuring reliable and high-performance electronics.


Advantage Of Lead-Free PCB Assembly Service


PCBA manufacturers are subject to RoHS standards, which require replacing traditional lead-based solders with lead-free alternatives for RoHS-compliant PCB assembly.

By eliminating the use of hazardous lead-based materials, our lead-free PCB assembly process significantly reduces the environmental footprint of electronic products. This approach not only complies with RoHS and other environmental regulations but also contributes to a greener and healthier planet for future generations.

Lead-free PCB assembly typically uses solder alloys that are free of lead, such as tin-silver-copper (SAC) alloys. Other materials may include lead-free surface finishes, fluxes, and conformal coatings designed for compatibility with lead-free processes.

PCB Assembly PCB Materials

FR4: The most commonly used Material for PCB.

FPC: Flexible Printed Circuit Board(or flex PCB) is a thin insulating polymer film that conductive circuit patterns are printed on, the most advantage for the FPC board is flexibility, which allows it to be the connection within a compact space or parts that need to bent. Also check the differences between Rigid-flex PCB and Flex PCB with stiffener.

Aluminum Board: The Aluminum PCB has good heat dissipation than FR4 PCB, which makes it suitable for boards that need quick/large heat dissipation, such as the LED Boards.

Rogers: When advanced electrical properties and performance are critical, such as Dielectric, dielectric constant, Rogers PCB boards would be the solution, normally only for professional high-frequency electronic engineers.
