MacDermid Alpha - Connectors & Interconnect Finishes
Chemical processes for the application of long lasting corrosion resistant coatings for connectors and interconnects. Whether you need durability, long lasting corrosion resistance, or functional final finishes, we have a wide range of chemical processes for finishing connectors and interconnects. The MacDermid Enthone brand of connector finishing technology meets the demands for increasingly complex shapes, finer features, and greater reliability. Through reduced consumption, greater metal selectivity, and increased productivity, every process is designed with the lowest cost of ownership in mind.
- Pre-treatments: specially formulated cleaners and activators for a wide range of substrate metals.
- Base metals: matte and bright coppers, nickels, and nickel alloys that provide a robust foundation for long-term adhesion and reliability.
- Tin: bright and matte deposits that are highly solderable and have excellent whisker resistance.
Cleaner and Degreasers
Alkaline electrocleaner for steel and copper
Activators
Fluoride containing acid salt for activation of copper, copper alloys, and steel
Bright, Matte
High speed plating for mid to high current densities, available in either sulfuric acid or MSA solutions.
Strike
Cyanide-based copper strike.
Nickel-Tungsten Alloy
Sulfamate based nickel-tungsten (35-45 wt% W) deposit for improved wear and corrosion resistance. High speed / wide plating window allows tight control of alloy composition.
Nickel-Phosphorus Alloy
Sulfamate based nickel-phosphorous (3-12% wt% P) deposit for improved corrosion resistance and non-magnetic properties. High speed / wide plating window allows tight control of alloy composition.
Semi-Bright Matte Pure Nickel
Deposits a semi-bright, slightly tensile stressed, and ductile layer. Ideal undercoat for precious and non-precious metal deposits.
