CHUKOH FLO COPPER-CLAD LAMINATES

Product catalog summary

Company Overview: Chukoh Chemical Industries, Ltd. is a Japanese company with multiple branches and technical development centers across Japan, including Tokyo, Fukuoka, Nagoya, Osaka, and international project departments. The company specializes in the development and production of advanced fluoroplastic laminates.

Product Overview: The document focuses on CHUKOH FLO® Copper-Clad Laminates, which are fluoroplastic circuit boards designed for high-frequency applications, particularly in the microwave band. These laminates are known for their stable dielectric constant, low dissipation factor, and excellent tracking resistance.

Key Features:

Stable dielectric constant across a wide frequency band.
Low dissipation factor in high-frequency bands.
Low water absorption and excellent heat resistance.
Suitable for satellite communications, mobile telecom, and other advanced electronic applications.

Product Grades: The document lists various grades of laminates, each with specific properties:

CGP-500: Standard substrate with high peel strength and dimensional stability.
CGS-500: Improved dielectric constant and dissipation factor.
CQF-500: Extremely low dielectric loss in the microwave band.
CGN-500: Reduced dielectric loss, excellent performance at 20 GHz or higher.
CGA-500: Mass-production substrate with high-frequency characteristics.
CGH-500: Lower dissipation factor for substrates with lower loss.
CGK-500: High dielectric constant for compact, lightweight substrates.
CGC-500: Combines strength and stability of ceramics with high dielectric constant.

Technical Specifications: The document provides detailed technical specifications, including density, thermal expansion, peel strength, flexural strength, resistivity, dielectric constant, dissipation factor, and water absorption for each laminate grade.

Compliance and Standards: The Matsuura Plant is ISO 9002 certified, and certain laminate grades have UL approval. The document also mentions QS accreditation and JAB certification.

Usage Guidelines: The document advises against using laminates in medical applications or where temperatures exceed 260°C, except for soldering. It emphasizes compliance with disposal regulations and the importance of reading safety data sheets and manuals.

Workability: CHUKOH FLO® laminates can be machined similarly to general substrates, with specific surface preparation required for through-hole machining.
