Polyethylene terephthalate (PET), commonly known as polyester resin, is the most prominent type of thermoplastic polyester.
Slightly oxidized copper foil surfaces can be cleaned using an alcohol sponge. However, for long-term or extensive oxidation, a sulfuric acid solution is required to clean and remove oxidation.
Cable taping methods include longitudinal taping and cross taping. Cross taping further divides into traverse taping and diagonal taping. Longitudinal taping is used for core wires where no overall stranding is required, and it does not require flexibility. Traverse taping is a high-speed process with good flexibility.
Films laminated aluminum foil with hot melt adhesive are divided into two types: aluminum/PE shielding films and aluminum/PVE shielding tapes. They use MQ-40 high-molecular-weight polymer as heat-sealing glue, which is non-toxic and eco-friendly and complies with the latest version of the EU RoHS environmental regulations. The other type is self-adhesive film laminated aluminum foil, which uses genuine EAA self-adhesive film, ensuring good heat-sealing bonding effects at lower preheating temperatures and long-term stability.
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.
