M-System integrated desmear–electroless copper was developed using design for six sigma techniques to provide a proven primary metallization system to fit the needs of the industry. The first stage of the process is a chemical desmear process designed for today’s variety of special resin systems. The process can be tailored to run in vertical or horizontal equipment. The second stage is our advanced electroless copper processes with options from low build to high build thicknesses.
The core of the process is our M-Condition line of conditioners selected for various material including FR-4 epoxies, polyimide, flex or high frequency, low loss materials, and our M-Activate system. Together with our patented M-Accelerate system, we can offer superior back light coverage and strong interconnects that consistently survive the stresses of thermal expansion and movement in reflow and assembly. M-Copper processes can be chosen for the specific thickness range desired given the dwell time and whether processing is vertical or horizontal.
The M-Copper Omega is a high dep metallization process combines a unique, patented activation sequence with a statistically designed electroless copper bath. The patented activation sequence utilizes nontraditional conditioning and acceleration steps to enhance glass coverage. This enhanced coverage yields superior post pattern plate backlight performance. The statistically designed electroless copper bath will produce the highest reliability on microvias and high aspect ratio holes.
M-Copper EF is the only electroless copper system on the market that is sold by an international plating supplier which can outperform local suppliers at a competitive price in both vertical and horizontal equipment. M-Copper EF is specifically formulated from decades of experience with electroless copper plating and modern innovations to allow for a revolution in quality and service in a segment of the PCB industry that rarely sees new offerings.
