Chapter 2: Profile of the Making Holes Conductive Use Cluster

Printed Wiring Boards Cleaner Technologies Substitutes Assessment: Making Holes Conductive

This section of the Cleaner Technologies Substitute Assessment (CTSA) describes the technologies that comprise the making holes conductive (MHC) use cluster. A use cluster is a set of chemical products, technologies, or processes that can substitute for one another to perform a particular function. In this case, the function is "making holes conductive" and the set of technologies includes electroless copper, carbon, conductive polymer, graphite, non-formaldehyde electroless copper, organic-palladium, and tin-palladium. Information is also provided for a conductive ink technology, which can be used to perform the MHC function on double-sided boards, but not multi-layer boards.

Section 2.1 presents process descriptions for each of the MHC technologies and describes the chemical composition of MHC chemical products that were evaluated in the CTSA. Section 2.2 briefly describes additional technologies that may be used to perform the MHC function, but were not evaluated. Section 2.3 summarizes the market for MHC technologies, including information on the total market value of MHC chemicals, and the market shares of electroless copper processes as compared to the technologies.
