Mobile Phone Shielding and Conductive Low Temperature Silver Paste
With the advent of the 5G era, mobile phone operating frequencies have significantly increased. To prevent equipment malfunctions due to electromagnetic interference and radiation from electromagnetic pulses on the human body, higher requirements for mobile phone shielding effectiveness have been proposed.
To address electromagnetic interference and pulse radiation, electromagnetic protection is necessary. This protection employs a sputtering layer using low-temperature silver paste.
Low-temperature silver paste, to achieve high conductive performance for mobile phone shielding, often requires the addition of large amounts of silver powder, leading to an increasing cost of the paste.
How to reduce costs is the focus for conductive silver paste manufacturers.
Conductive Silver Paste for Mobile Phone Screening and Low-Temperature Silver Paste Resin LR9100
The low-temperature silver paste resin LR9100 significantly reduces the amount of silver powder used.
The special components of the low-temperature silver paste resin LR9100, with their spatial steric effect, not only enhance the wettability and dispersibility of silver powder but also promote the alignment of silver powder particles.
Compared to conventional mobile phone shielding conductive silver inks forming conductive patterns, the LR9100 resin-based low-temperature silver inks can produce a denser conductive layer microstructure.
The LR9100 conductive silver paste demonstrates significantly lower resistance even when printed at thinner thicknesses and narrower linewidths, achieving ideal shielding effectiveness.
The introduction of LR9100 not only reduces the amount of silver powder used but also enhances the conductivity of the silver paste.
The LR9100 resin conductive silver paste exhibits a resistance value less than 1 ohm after curing, meeting not only the resistance requirements for shielding but also the temperature resistance requirements of the shielding material.
