Questions About Materials?

Board Construction Options

Board construction generally includes standard single and double sided, single sided with pre or post bonded metal cladding, mixed dielectric multilayers, PTFE multilayers, and metal core multilayers.

Single/Double Sided Circuits

Thickness availabilities from .002" to .250". Laser routing for thin dielectrics with complex profiles and tight circuit edging requriements. Consistent development with wire-bondable gold applications.

Metal Backed Circuits

Attachment options available include fusion bonding, fabrication, and post fabrication. Most fusion bonding is assisted with material work from Tatonic, Rogers, and Arlon. Our metal backed circuits reduce waste, improve RF grounding, expand normal temperature ranges, and more.


Full PTFE and mixed dielectric construction available, generally completed with FR-4 and microwave laminate. MCN offers embedded copper heat sink cores and thermoclastic bond films (including FEP lamination.) We strive to keep core thickness as thin as .005".
