8 Layer Fr4 circuit board Manufacturing Service

8 Layer Fr4 circuit board Manufacturing Service

♦ What's Printed Circuit Board Manufacturing Service?

​​Printed Circuit Board Manufacturing Service​​ refers to the professional process of producing ​​Printed Circuit Boards (PCBs)​​ based on customer designs. PCBs are essential components in electronic devices, providing mechanical support and electrical connections for components like resistors, capacitors, and integrated circuits.

♦ What's Fr4?

FR4 (or FR-4) is a glass-fiber-reinforced epoxy-resin laminate.
It is the most common substrate used to make rigid printed-circuit boards (PCBs).

♦ ​​Key Features of PCB Manufacturing Service:

​​

• Design Submission​​

Customers provide design files (usually in ​​Gerber format​​, along with drill files, BOM, and assembly drawings).

Engineers review the design for manufacturability (DFM checks).

• ​​PCB Fabrication Process​​

​​Material Selection​​ – Choosing substrate materials (e.g., FR-4, Rogers, flexible PCBs).

​​Printing & Etching​​ – Transferring the circuit pattern onto copper-clad laminate.

​​Layering & Lamination​​ (for multi-layer PCBs).

​​Drilling & Plating​​ – Creating vias and through-holes.

​​Solder Mask & Silkscreen​​ – Applying protective coating and component labels.

​​Surface Finish​​ – Options like HASL, ENIG, OSP, or immersion silver/gold.

​​Electrical Testing & Inspection​​ – Ensuring no shorts or open circuits (e.g., flying probe test, AOI).

• ​​Additional Services (Optional)​​

​​PCB Assembly (PCBA)​​ – Soldering components onto the board (SMT or through-hole).

​​Testing & Quality Control​​ – Functional testing, burn-in testing, etc.

​​Box Build & Packaging​​ – Full product assembly.
