♦ 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:
Customers provide design files (usually in Gerber format, along with drill files, BOM, and assembly drawings).
Engineers review the design for manufacturability (DFM checks).
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).
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.
