Overview of Military Printed Circuit Boards
Specialized printed circuit boards, military-grade PCBs serve core defense applications like military aircraft avionics, battlefield communication gear, and missile control systems. They feature enhanced durability to endure harsh environments—including extreme temperatures, heavy vibration, chemical corrosion, and EMI. These PCBs deliver stable, long-lasting performance for mission-critical operations.

Military PCB Manufacturing Process
1.Engineering Check (DFM): Review and preparation of design files, ensuring compliance with military specifications.
2. Inner Layer Processing: Imaging, etching, and AOI (Automated Optical Inspection) of the internal circuits.
3. Lamination & Drilling: Stacking and bonding all layers under pressure, followed by precise drilling of holes (vias).
4. Plating: Chemically and electrically plating copper to create highly reliable Plated Through-Holes (PTH).
5. Outer Layer Patterning & Etching: Defining the final external circuitry and then etching away excess copper.
6. Finishing & Test: Applying solder mask and military-grade surface finishes (e.g., ENIG), followed by mandatory 100% Electrical Testing (E-test) and final inspection.
What documents are required for custom PCB manufacturing?
1. Gerber files (RS-274X)
2. BOM (if PCBA needed)
3. Impedance requirements & stack-up (if available)
4.Test requirements (TDR, network analyzer, etc.)
What do Gerber files typically contain?
Normally,Gerber files includes: PCB Type,Board thickness, ink color, surface treatment process ect,.
