Carbon Pill Custom Buttons Conductive POS Machine

Ever wondered about those little carbon pills in your silicone rubber keypad? They’re pretty essential! Carbon Pills & Graphite Pads, as they’re called, play a big role in making your keypad work smoothly without breaking the bank.

So, what exactly are they? Well, they’re made by mixing carbon with a stretchy material called elastomer, usually silicone. This combo lowers the resistance of the material, making it easier for electricity to flow through. The key here is the size of the carbon particles – the smaller they are, the less resistance they create.

These carbon pills are a staple in things like carbon pill buttons, switches, and conductive keypads. They’re what make pressing buttons on your gadgets feel so satisfyingly smooth!

Conductive Ways

Manufacturers usually have four ways to ensure the keypad works just right for its purpose:

Conductive Ink: This ink is applied to make pathways for electricity, ensuring smooth operation.

Carbon Pills: These little guys we talked about earlier help reduce resistance, making sure your keypad responds swiftly.

Metal Dome: These are tiny metal pieces that provide tactile feedback when you press a button.

Golden Pills: Also known as golden pills, these are similar to carbon pills but use gold instead, providing reliable conductivity.

Each method has its own perks, and manufacturers choose based on the specific requirements of the keypad and its intended use.

Process

When manufacturing carbon pill silicone buttons, the process differs from using conductive ink keypads. While conductive ink keypads involve applying ink after compression molding, carbon pill silicone keypads start by combining carbon pills directly into the silicone. These pills are typically made using die-cutting tools or compression molding and are available in two types: textured finish and smooth finish.

Here’s how it works: Before the compression molding begins, the carbon pills are carefully placed into the mold cavities using a positioning tool. As the silicone undergoes vulcanization in the mold, the carbon pills become integrated with it. However, getting the timing and temperature just right is crucial. If the temperature is too low, the carbon pills might not stick properly, leading to them falling out. On the other hand, if the temperature is too high, the carbon pills could end up melting into the silicone, which isn’t ideal. So, finding the perfect balance is key to ensuring the carbon pill silicone buttons turn out just right.
