1. Introduction of IsoClad 933:
Rogers IsoClad 933 laminates are non-woven fiberglass/PTFE composites designed for PCB substrates.

Utilizing non-woven reinforcement, these laminates are ideal for applications requiring conformability.

IsoClad 933 employs extended random fibers and a proprietary process to enhance dimensional stability

and mechanical strength.

2. Features:

• Dielectric Constant (DK): 2.33 at 10GHz/23°C
• Dissipation Factor: 0.0016 at 10GHz/23°C
• Peel Strength: 10 lbs. per inch
• Water Absorption: 0.05%
• Outgassing: 0.03% TML, 0 CVCM, 0.02% WVR
• Dk Uniformity: Excellent

3. Benefits:

• Flexibility: Greater than woven fiberglass
• Isotropy: Highly isotropic in X, Y, and Z axes
• Dk Stability: Maintained across varying frequencies
• Dimensional Stability: Improved
