Sales plan
- Sales start: June 1, 2007
- Sales target: 10,000 units per month (at mass-production stage)
- Sales price: varies with size, specifications and volume
Main Features
- Precisely controlled characteristic-impedance
- Characteristic impedance of circuits is precisely controlled. Both of single-ended transmission and differential transmission circuits are available.
- Various shielding structures
- Use various mesh pattern shields, and shield materials including new materials depending on customer's requirement.
- Reduces reflection-loss, cross-talk, conductor-loss, and dissipation-loss to the utmost limit
- Various base-materials for various usage
- New base-material such as LCP (Liquid Crystal Polymer) and PEN (Polyethylene Naphthalate), etc. are available for special environmental requirements such as "moisture-resistance" and "Low-VOC."
These new base-materials also have advantage with its space saving (thinner than conventional material), and low-thermal dissipation properties.
