What is the ISOLA FR406N Substrate Fabrication Process?

The fabrication process for ISOLA FR406N substrate involves several key steps to ensure high-quality printed circuit boards (PCBs) that meet performance and reliability standards. Here’s an overview of the typical fabrication process for FR406N:

1. Material Preparation: The FR406N substrate starts with a base laminate material consisting of woven glass fabric impregnated with an epoxy resin. The resin is formulated to enhance the electrical and thermal properties of the substrate.
2. Copper Cladding: The laminate is then coated with a thin layer of copper on one or both sides. This copper layer is used to create the circuit traces and pads. The copper cladding is typically applied through a lamination process that bonds the copper foil to the epoxy resin.
3. Layering and Lamination: For multi-layer PCBs, additional layers of FR406N laminate are stacked with copper layers in between. The stack is then subjected to a lamination process, where heat and pressure are applied to bond the layers together, forming a solid, integrated substrate.
4. Drilling and Via Formation: Holes are drilled into the substrate to create vias and through-holes for electrical connections between different layers. The drilling process must be precise to ensure proper alignment and functionality.
5. Copper Plating: After drilling, the holes are plated with copper to establish electrical connections between the layers. This process involves depositing a thin layer of copper onto the walls of the drilled holes through an electroplating process.
6. Etching: The substrate undergoes an etching process to remove unwanted copper and define the circuit traces. This involves applying a photoresist layer, exposing it to light through a mask, and then etching away the exposed copper to create the desired circuit pattern.
7. Lamination of Solder Mask:A solder mask is applied to the surface of the PCB to protect the copper traces and prevent solder bridges during assembly. The solder mask is typically a polymer coating that is cured using UV light.
8. Silkscreen Printing: Text and other identifying marks are added to the PCB using a silkscreen printing process. This involves applying ink to specific areas of the PCB to indicate component placement, test points, and other relevant information.
9. Final Inspection and Testing: The fabricated PCBs undergo thorough inspection and testing to ensure they meet electrical and mechanical specifications. This may include visual inspection, electrical testing, and functional testing to verify performance and reliability.
10. Cutting and Routing: Finally, the PCBs are cut and routed to the required size and shape. This involves separating individual boards from larger panels and machining any necessary cutouts or slots.
