Customize Silicone Rubber Conductive Carbon Pill Keypad
Carbon Pills also called as conductive pills， conductive graphite pill.Carbon Pills are made by mixing 60% VM Q and 40%conductive carbon black.Rubber Keypads and Keyboard， Rubber Keypads ,Custom Rubber Keyboard ,Custom Rubber Keypads ,Silicone Button Pad.Conductive carbon pills are commonly used in si icone rubber keypad as conduction part Conductive Carbon Pills are widely used in silicone rubber keypad， rubber button pad for conductivity Instead of at act switch， they touch the PCB directly and connect the circuit.
Carbon Pills&Graphite Pads are widely used in slic one rubber keypad due to its economy and low resistance.Conductive carbo made by adding carbon to macromolecule elastomer(such as silicone) to reduce its volume resistance.The resistance depends ol part idle properties and fl lng quantity.The sam ller the carbon part idle， the lower resistance the conductive carbon pils.Carbon widely used in carbon pill button， carbon pill switch and conductive keypad.
Rubber Button Pad can be divided int on conductive rubber keypad and non-conductive rubber keypad.Conductive rubber keypad includes carbon
pill button pad， conductive ink printing rubber keypad， metal dome button pad， gold pill rubber buttons and nickle rubber keypad.
For low resistance， metal pills rubber button pad is a good choice， but the cost will be high.Carbon pil rubber keypad and conductive printing
buttons are the most common silicone keypads.
Carbon pills are one kind of small elastomer piece with carbon powder The resistance is depends on the
carbon particle property Generally, carbon pill rubber keypad resistance is 10-10 Ohms. Conductive button
keypad with carbon pills are very popular because its low cost, low resistance and long life time. The
service time can reach over than 10 million
But carbon pill rubber buttons also have the disadvantages. There are very limited shapes can choose, round,
rectangular and oval. Other shapes need custom made. but the customization costis very high as carbon pill
die cutting tool is very expensive. Second, carbon pills conductive rubber key buttons once are molded, they
can not be reworked if there are some pills doesn'tstick to the silicone button pad Carbon pills are molded
with silicone keypad in compression molding curing.
Conductive Ink Rubber Buttons
Conductive ink is the ink contains conductive particle, like carbon. silver copper and other metal powder
Conductive ink is the most economical way in four conduction ways. Resistance is 50-350 Ohms Thicker
ink printing can reduce the resistance. Conductive ink can be printed into different shapes for rubber keypad
button.
