Custom Multilayer PCB Manufacturing High-TG FR-4 & PTFE Specialists for Mission-Critical Applications
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.
Customization Service
- Gerber files (RS-274X)
- BOM (if PCBA needed)
- Impedance requirements & stack-up (if available)
- 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. 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.
