22521 Nonreinforced Dielectric Materials Nonreinforced dielectric materials include resin-coated copper foils, unclad photoimageable dielectric materials, and non-photoimageable dielectric materials 225211 Resin-Coated Copper Foils Resin-coated foils are the most common materials used for build-up multilayer microvia applications Many product variations are available and fit well within the existing multilayer-manufacturing infrastructure Epoxy-based coated foils are the most common and have performance properties similar to FR-4 but with no glass reinforcement Peel strengths, thermal performance, and electrical properties are excellent A variety of other resin systems are also being developed and starting to be used for coated foil build-up applications Resin-coated foils come in two general types with either one or two resin layers One-pass coated foils have a single B-stage layer designed to flow, fill, and provide thickness control at the same time.

Two-pass coated foils have a C-stage resin layer adjacent to the foil and a B-stage layer for flow and fill The fully cured C-stage layer acts as a stop during the lamination process, typically enabling better thickness control Resincoated foils are available in a variety of thicknesses, yielding between 10 mil (25 micron) and 30 mil (76 micron) thick, finished dielectric layers Copper foils most commonly used are 1/2 oz (18 micron) and 3/8 oz (1334 micron), but there is substantial interest in thinner copper foils for improved laser efficiency and better fine-line circuitry definition 225212 Other Resins Since build-up technology is still in its relative infancy but evolving rapidly, many different and diverse approaches are being investigated for the resins used and variations on the via-formation process.

Low-Dk/Dj resins such as polyphenylene ether (PPE) are being used to address signal speed and integrity demands in resin-coated foil build-up structuresAnother approach is to use additively plateable resin and use the copper as a sacrificial carrier, eliminating the need to laser through copper An additively plateable resin has the characteristic of high surface adhesion to electroless copper or direct metallizationThe sacrificial foil makes it compatible with normal multilayer lamination processes, saving the need for expensive coating machinery, while also protecting the thin dielectric from harm until it is laminated to the printed circuit This also gives excellent surface topography for good peel strength The properties of a resin-coated foil are given in Table 224 See IPC- 4104 specification sheets 12, 13, and 19 through 22 for more complete material performance information..

Laminate suppliers should be contacted when special needs arise, as the resulting composite will require understanding of fabrication and design issues. Resin-coated foils come in two general types:

One-pass coated foils have a single B-stage layer designed to flow and fill and to provide thickness control, all at the same time. Two-pass coated foils have a C-stage resin layer against the foil and a B-stage layer for flow and fill. The fully cured C-stage layer acts as a stop during the lamination process, typically enabling better thickness control.

With the exception of the laser process, all the basic technology to produce SBU using resin-coated foil is the same as, and found in, most multilayer PWB production operations Another alternative is to use additively platable resins In this approach, the copper foil acts as a sacrificial carrier The process is similar to that described earlier, but the first step after lamination is to etch off all the copper chemically This eliminates the need to laser through copper and makes acquisition of registration targets simpler The structure left behind by the copper also gives excellent surface topography to the resin for good peel strengths from the subsequent additive plating stepThis approach allows for extremely fine feature definition and much greater laser efficiency 225213 Unclad Nonreinforced Photoimageable Dielectric Materials Material chemistry options for this group include epoxies, epoxy blends, polynorborenes, and polyimides.

Elements of measuring equipment (length, roughness)

They can be applied as liquid or dry film, negative or positive imaging, and can be solvent- or aqueousdevelopable To improve the dielectric s adhesion to copper, most dielectric suppliers require a copper pretreatment with a black oxide or conversion coating (oxide replacement) prior to application of the dielectric Most of these materials are either epoxy or epoxy- and novolac-based to provide high Tg and good plating, and most provide adhesion values for plated copper of at least 11 kg/cm at a 25 m copper thickness Typically these dielectrics are metallized using conventional solvent swell and permanganate etching techniquesThe liquid materials use only safe solvents (those not known to lead to harmful health effects with prolonged exposure Typical microvias are seen in Chap 23; Fig 2327 and Chap 29; Figs 295 and 2912.
