DuPont™ ELECTROPOSIT™ 1000
Description
The Dow High Aspect Ratio Plating System (SHARP) is designed for reliable through-hole plating of thick multi-layer printed circuit boards with hole aspect ratios up to 15:1. Dow can also provide processes for plating through-holes with aspect ratios greater than 15:1. Contact your Dow Technical Representative for more information.
The SHARP process consists of ELECTROPOSIT™ 1000 Plating Additives and a specially-developed high acid, lowcopper plating bath. This combination offers excellent throwing power at plating rates.
