High purity aluminum foil offers excellent electrical conductivity, easy etching and effective EMI shielding. Aluminum foil is versatile, easy to form, and resistant to heat and corrosion. Polypropylene (PP) offers high impact resistance, mechanical strength, and resistance to a wide range of solvents, acids and bases.

Features

Applications

Shielding laminates consist of at least two materials whose combined performance exceeds that of their individual components. In our context, we refer to shielding laminates consisting of both metals and non-metals, usually involving a combination of PET, PP, PI, PPS, PTFE with metals such as copper and aluminum.

Metal shielding laminates are produced by continuously bonding two thin metal sheets or natural metal films to one side of a thermoplastic core. These cores form sheets that are lighter in weight, easy to fabricate, flat and durable.

Copper/PET shielding tapes is primarily used in various fields, such as extremely fine coaxial wires, low-loss antennas (computers), solar cell wires, etc.

EMI solutions include three main approaches: electromagnetic interference shielding, printed circuit board grounding, and electromagnetic interference absorption.

  • Electromagnetic Interference Shielding involves blocking electromagnetic noise and attenuating cable-collected noise. It uses high-reflectance materials (usually low-resistance metals) to encase or seal openings in target devices for EMI and EMS solutions.
  • Printed circuit board (PCB) grounding is the process of electrically grounding electronic equipment to prevent electrocution, treating the earth as a large conductor at zero potential. There are two types of grounding: rack grounding and PCB signal grounding.
  • Electromagnetic Interference Absorption (EMI Absorption) utilizes magnetic loss, dielectric loss, and conduction loss to convert radio wave energy into thermal energy. EMI absorbers have a wide range of applications.
