CIRCUPOSIT™ 6500 Electroless Copper Process
CIRCUPOSIT™ 6500 Electroless Copper Process Flow Horizontal Application
As HDI designs, especially those incorporating every layer interconnect (ELIC) technology to enable increasing functionality become more common in today’s mobile devices, tablets, and wearables, the demands on interconnect density and reliability are continuously challenged.
To meet these challenges, Dow has created the CIRCUPOSIT 6500 Horizontal Electroless Copper System, based on an Ionic Catalyst and a Tartrate-based Electroless copper for ELIC and IC Substrate applications.
Key Features of the process:
- Conditioning system, coupled with the Catalyst and Electroless copper designed for coverage on today’s advanced dielectrics.
- Horizontal process for ease of handling, uniform chemistry application, reduced operator exposure to chemicals & vapors
- Highly stable Alkaline Ionic Catalyst, with little or no sludge formation
- Tartrate-based electroless copper formulated to provide excellent throwing power, bath stability, and ease of treatment.
- Excellent copper to copper adhesion of deposit for optimum copper joint reliability.
- Can be used for MSAP product/processes with ELIC or IC substrate applications
- Meets advanced reliability requirements: HCT, Pin-Pull, Thermal Stress, Thermal Shock
