4. Layer Stackup: Stack the prepared substrate layers with copper foil layers according to the design specifications. Ensure that layers with higher halogen content are minimized in the stackup.
5. Circuit Patterning: Use a process like photolithography to transfer the PCB design onto the copper layers. A photoresist is applied, exposed through a mask, developed, and then etched to remove unwanted copper, leaving behind the desired circuit pattern.
6. Drilling: Drill holes for component mounting and interconnection between layers. Drilling should be performed with appropriate equipment to minimize contamination and ensure accuracy.
7. Plating: Apply a thin layer of copper to the walls of the drilled holes through a process called electroplating. This forms the vias that facilitate electrical connections between layers.
8. Surface Finish: Apply a surface finish to protect exposed copper and ensure solderability. Common surface finishes for Low CET PCBs include immersion silver, immersion tin, and OSP (Organic Solderability Preservatives).
9. Solder Mask Application: Apply a solder mask to the PCB surface, leaving openings for component pads and vias. The solder mask protects the copper traces from oxidation and provides insulation.
10. Component Assembly: Mount components onto the PCB using soldering techniques such as reflow soldering or wave soldering. Use low-temperature soldering methods to minimize halogen release during assembly.
11. Testing and Inspection: Conduct electrical testing and visual inspection to ensure the functionality and quality of the assembled PCB. Test for adherence to low CET requirements and halogen content limits.
12. Final Inspection and Packaging: Perform a final inspection to verify that the PCB meets specifications and standards. Once approved, package the PCBs for shipment to customers or assembly into end products.
