Engineering considerations

High-reliability acceptance class

Applications of this kind typically require IPC-6012 Class III acceptance, with stricter criteria for hole-wall copper, layer registration and plating integrity than Class II. Manufacture and inspection can be organized to Class III.

Material and thermal matching

Where the temperature span is wide, matching material Tg and thermal expansion matters more than layer count alone. High-Tg (>170°C) and hybrid high-frequency constructions are available; specific grades are reviewed per project.

Applicable board types

The board types below are the ones that come up most often in aerospace applications. Each link goes to that board type's capability page with material, layer-count and process ranges. Combined constructions such as hybrid lamination or embedded copper are also available.

• Multi-Layer PCB
• High Frequency PCB
• Rigid-Flex PCB
• Resin Plugged Via PCB

Frequently asked questions

How long does a aerospace project take from enquiry to prototype?

Quotations are returned within 30 minutes as a rule. Expedited prototype lead times run by layer count: double-sided 24 hours, 4-layer 48 hours, 6–8 layer 72 hours, 10–12 layer 96 hours; single-stage HDI at 6 layers is 48 hours. Volume lead times are set by order quantity.

Which inspection and material documents can you supply?

As standard we supply a certificate of conformance, material certifications with lot records, and electrical test records; impedance test reports and microsection analysis are available on request. Acceptance can be run to IPC-6012 Class II or Class III, which must be stated on the order.
