Transportation
Board requirements across transportation vary widely, and selection is usually driven by some combination of heat dissipation, signal integrity, structural space and reliability grade. Below are the engineering considerations that come up most often in this area, together with the 4 applicable board types we already manufacture.
Engineering considerations
- Vibration and mechanical endurance
- Vehicle and rail environments impose sustained vibration, where solder-joint and hole-wall fatigue are the main failure modes. Acceptance to IPC-6012 Class III is available, as are press-fit hole constructions.
- Wide operating temperature
- On-vehicle and outdoor equipment sees a wide temperature span, where material Tg and thermal expansion matching determine interlayer reliability. High-Tg (>170°C) materials are available, with grades reviewed per project.
Applicable board types
The board types below are the ones that come up most often in transportation applications. Each link goes to that board type's capability page with material, layer-count and process ranges. Combined constructions across board types, such as hybrid lamination or embedded copper, are confirmed by engineering review.

Frequently asked questions
- How long does a transportation 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. Standard lead times and production scheduling are confirmed separately against order volume.
- 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.
This page describes general engineering considerations for this application area and the board-type capabilities we already hold. It is not a commitment on a specific project. Exact stack-up, material grade, tolerances and acceptance criteria are confirmed through engineering review and in writing.
Routine enquiries are answered within 30 minutes. Once you upload Gerber files and technical requirements, engineering returns manufacturability findings together with the quotation, so design conflicts surface before production rather than after.
