What CAC does

CAC, Inc. is a privately held U.S. manufacturer of CAC® (Copper Aluminum Copper) bonded lamination foils used as separator sheets in multilayer printed circuit board (PCB) fabrication. The company bonds thin copper foil to one or both sides of an aluminum separator sheet inside a proprietary clean-room process — branded "Clean Room in a Box" — that eliminates copper-surface particles and dents five microns or larger, addressing yield losses on high-density, fine-line, and gold-feature circuit boards. Its product portfolio spans double-sided CAC Lamination Foil, single-sided CA and AC Lamination Foil variants, standalone solid aluminum foil for drilling entry, and aluminum separators, all produced at a Lake Forest, California headquarters facility.

Beyond its core CAC® line, CAC operates a light gauge metal toll processing service from a Bloomingdale, Illinois facility, processing thin-gauge aluminum, stainless steel, copper, titanium, and coated products that larger roll levelers cannot handle. The business model is primarily one-time product sales of consumable lamination foils plus professional-services revenue from toll processing, sold both directly to PCB OEMs and through a four-region distributor network — Insulectro in North America, CCI Eurolam in Europe, Multicomplex in Asia, and A.J. Englander in the Middle East — supplemented by trusted-partner relationships with Denkai America and JX Metals Corporation. Pricing is quote-based and not publicly disclosed, consistent with negotiated specialty-materials contracts.

The company has held ISO 9001 quality certification continuously since 1996 (currently ISO 9001:2015, valid through 2027) and positions itself as the inventor and technology leader in bonded copper separator products. Its go-to-motion is hybrid: content marketing through cac-inc.com and LinkedIn for top-of-funnel demand generation, paired with the channel-partner network for global fulfillment and field technical support. CAC's claimed quantifiable outcomes include 30–50% labor productivity gains for PCB fabricators, support for thin foils down to 9µm, and fine-line capability as small as 50µm.

Core offering

CAC, Inc. manufactures proprietary CAC® (Copper Aluminum Copper) bonded lamination products — thin aluminum separator sheets with copper foil attached to one or both sides in a state-of-the-art clean room — for printed circuit board fabricators requiring particle- and dent-free copper surfaces during multilayer lamination. The company also provides light gauge metal toll processing services (cut-to-length, slitting, paper interleaving, PVC application, line marking, aluminum degreasing) for difficult-to-handle thin aluminum, stainless steel, copper, titanium, and coated products.

Product overview

CAC, Inc. is a manufacturer of CAC® (Copper Aluminum Copper) bonded copper products for the PCB (printed circuit board) industry. The product portfolio centers on CAC® branded lamination foils—available in double-sided (CAC Lamination Foil) and single-sided variants (CA Lamination Foil, AC Lamination Foil)—which feature copper foil bonded to aluminum separator sheets to protect copper surfaces during multilayer PCB lamination. The company also offers aluminum separators sold separately, solid aluminum foil for drilling applications, and toll processing services for light gauge metals. All CAC® products are manufactured in the company's Lake Forest, California facility and distributed globally through authorized partners.
