Definition

This technology provides a cost-effective substitute for rigid-flex circuit technology. This is garnered by eliminating the use of more expensive polyimide-based flexible substrates and a streamlined process flow since it requires only one lamination cycle (no lamination cycles if only 2 layers). The flexible portion is achieved by controlled-depth milling away the FR4 material in the bend area. While this allows for multiple bend cycles as shown in limited industry testing, we would recommend this technology only for large radius, flex-to-install bends.
