Shielding film for high speed transmission FPCs（Ultra thin and high shielding effect）
UL94 VTM-0（Combination with Kapton 50H）

These are thinner types of shielding film with a high shielding effect. With the miniaturization of electronic devices and the increase in mounted components, the trend of downsizing is continuing. In addition, the demand for high shielding in the high frequency range has been increasing in recent years, and our products can meet this demand. Depending on the required shielding effect and thickness, you can select from SF-PC®3900R1-C or SF-PC®3900R2-C.
High shielding effect
Product Shielding effect 1GHZ 10GHZ SF-PC3900R1-C Above 80dB Above 85dB SF-PC3900R2-C Above 85dB Above 95dB
Realize the total thickness of 12µm/13µmWhile maintaining a high shielding effect, the total thickness is as thin as 12μm (SF-PC3900R1-C) and 13μm (SF-PC3900R2-C).
