Custom PCB Reliable PCB Solutions for Aerospace, Naval & Ground Defense Systems

Xingqiang Custom Military-Grade Multilayer PCB for Tactical & Industrial Use:

We are Xingqiang Circuit Board Technology Co., Ltd., a professional manufacturer of custom PCBs. This rugged multi‑panel PCB is designed for high‑reliability communication, sensor interface, and industrial control applications. Built with 4–6 multilayer structure and ENIG plus gold finger surface finish, it delivers stable signal integrity and strong wear resistance. Using high‑TG FR‑4, Rogers or PTFE materials, it supports extreme temperature, shock, and vibration resistance. It can be customized to military‑grade standards complying with MIL‑STD, ideal for defense, aerospace, tactical communication, and industrial systems.

1. Gerber files (RS-274X)
2. BOM (if PCBA needed)
3. Impedance requirements & stack-up (if available)
4.Test requirements (TDR, network analyzer, etc.)

We’ll reply within 24 hours with a free quote, DFM report, and material recommendation.

What do Gerber files typically contain?

Normally Gerber files Include:PCB Types,Product thickness, Ink color, Surface treatment process and If SMT processing is required, component BOM and tag drawing are also required.

Main Steps of Military-Grade PCB Production
1. Material Preparation

Select MIL-STD compliant high-reliability materials (e.g., high-Tg FR-4, PTFE) and cut to size.
2. Inner-Layer

Fabrication,Photolithography, etching and AOI inspection to form inner circuits.
3. Layer Lamination

Stack inner layers, prepreg and outer copper foils; bond via high temp/pressure.
4. Drilling & Plating

CNC drill vias/holes; desmear and copper-plate for interlayer electrical connection.
5. Outer-Circuit & Solder Mask

Form outer circuits via photolithography/etching; apply and cure military-grade solder mask.
6. Surface Finish & Legend Printing

Apply ENIG/hard gold finish; print and cure component legends.
7. Routing & Shaping

CNC/laser trim the board to final dimensions.
8. Reliability Testing & Packaging

Conduct thermal shock, vibration and electrical tests per military specs; vacuum-seal and deliver in anti-static packaging.
