Communication

Engineering considerations

High-frequency materials and loss

Insertion loss in an RF chain is dominated by the dielectric. Rogers 4350B/4003C/3003, Arlon 85N and Taconic RF-35 are available, including hybrid constructions with FR-4.

High-speed digital and layer count

Backplane and switching products run high layer counts with strict length matching. Standard volume production reaches 40 layers; low-loss options include Isola FR408HR/I-Speed and Panasonic Megtron 6/7.

Applicable board types

The board types below are the ones that come up most often in communication 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.

Frequently asked questions

How long does a communication 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.
