Stretchable conductive silver paste XFJ215

Product Name

Name:Stretchable conductive silver paste

Product Overview

Stretchable conductive silver paste is a conductive material with special properties, mainly used in the field of flexible electronics, capable of maintaining good conductivity under deformation conditions such as stretching and bending. The XFJ213/214 silver paste provided by Xianfeng Nano is a low-resistance elastic conductive silver paste with stretchable and high-strength bending characteristics, featuring excellent adhesion to materials like TPU, PC, PVC, and PET. It has good printability, moderate baking temperature, and retains good conductivity even after being stretched by 50%. It is widely used in projects requiring high-strength bending and stretching deformation, such as flexible electroluminescent devices and in-mold injection of membrane switches. During operation, it is recommended to use a 200-300 mesh screen printing. The XFJ215 silver paste from Xianfeng is a stretchable high-conductivity low-temperature silver paste with curing conditions of 90°C for 25 minutes, folded in half, pressed with a 2.5kg weight for 1 minute on each side, then flattened with a 2kg weight for 30 seconds, and after 10 repetitions, the change in resistance (△R) is less than 200%.

Product Features

Bending Resistance Performance: Mini keyboards frequently undergo pressing and some degree of bending during daily use, such as the mini keyboards of portable electronic devices. Bending-resistant conductive silver paste, through a unique formula—using highly flexible polymer resin as a binder, combined with specially shaped silver powder—can withstand thousands or even tens of thousands of bending tests.High Conductivity: Silver itself is an excellent conductive metal, and the high purity silver powder content in the bending-resistant conductive silver paste ensures excellent conductivity. Compared to traditional conductive materials used in mini keyboards, it significantly reduces the resistance of signal transmission, making key responses more sensitive, and data transmission rapid and stable, effectively enhancing the overall performance of the mini keyboard.Good Adhesion: The circuits of mini keyboards are usually printed on flexible substrates like PET and PI.

Application Fields

Flexible Keyboard: Flexible keyboard circuitry printed for laptops, tablets, etc., meeting the conductive needs of keyboards in folded and curved states. Flexible Display: Electrode circuits and touch circuits for flexible OLED and AMOLED screens, supporting screen folding and curling, such as in foldable phones and flexible wristband displays. Wearable Devices: Conductive circuits for making smart wristbands, smart clothing, and flexible sensors like heart rate sensors and pressure sensors, adapting to deformations during human activities. Electronic Tags and Smart Packaging: Conductive circuits for flexible RFID electronic tags and bendable smart packaging, adapting to deformations during packing and transportation.
