What is Heavy Metal Military Plate PCB?
Heavy metal military plate PCB refers to printed circuit boards used in aerospace, aviation and military equipment. These specialized boards are designed to operate in extreme environments and deliver high reliability, anti-interference capabilities, high temperature resistance, high pressure resistance, and aeronautical characteristics. Given their critical applications in national defense security, aircraft safety, and mission success, aerospace and military PCBs must adhere to extremely stringent manufacturing standards that ensure performance under extreme conditions and harsh working environments.
Manufacturing Process
1. Pre-Production & Engineering (DFM): Importing design data and conducting rigorous Design for Manufacturability checks to ensure compliance with military specifications.
2. Inner Layer Processing: Imaging and etching the copper, followed by Automated Optical Inspection.
3. Lamination: Bonding layers, prepreg, and copper foil together under high temperature and pressure into a single rigid board.
4. Drilling & Plating: Drilling required holes and making hole walls conductive using chemical and electroplating processes.
5. Outer Layer Processing & Final Etching: Forming circuit patterns on outer layers using plating and etching techniques.
6. Finishing & Testing: Applying solder mask, performing military-grade surface finishing, conducting 100% Electrical Testing, and stringent final quality inspection.
Frequently Asked Questions
How many layers can your circuit boards provide?
We typically provide 1-30 layer boards, and in special cases, we can stack more layers.
Do your circuit boards support customization?
Yes, we support customized designs. You can send us your Gerber files and BOM list, and we will provide you with an accurate quote based on the information and market conditions.
What do Gerber files typically contain?
Normally Gerber files include: PCB types, board thickness, ink color, surface treatment process, and if SMT processing is required, component BOM and tag drawing are also required.
What is your minimum order quantity for PCB boards?
Our minimum order quantity is 1 piece (5 square meters), with larger quantities receiving bigger discounts.
Do you have relevant certification certificates to support this?
We hold numerous important certifications, including ISO, UL, CE, and RoHS. All products undergo rigorous quality testing.
What payment method do you usually use?
For small orders, samples, or urgent payments, we accept Western Union. For large orders, we recommend T/T, which ensures the safety of both parties.
