Custom conductive carbon pills silicone keypads

Conductive carbon pills silicone keypads also called Conductive black carbon pills silicone keypads, in the custom manufacturing process, the keypad's surface can be customized with silk-printed characters and patterns of various colors. A black suction cup can also be used on the bottom of the keypad to press the conductive black pills on the male mold during molding letting it produce a sensing conductive function when pressed. Conductive carbon pill silicone keypads are usually designed with elastic webbing. When the button is fully pressed, the elastic webbing will deform evenly and produce a spring-like tactile response. The center point of the button contact is concave and directly connected to the circuit. When the conductive black silicone keypad is released, the elastic webbing will return to its original position and generate positive feedback.

The working principle of conductive carbon pill silicone keypads

The working principle of the conductive carbon pill silicone keypad is that the conductive black pills on the back of the button contact the printed circuit board to send out a signal to work.

Application of conductive black pill silicone keypads

The use of conductive carbon pills is a common conductive method for closing circuits on circuit boards. Silicone keypads realize circuit conduction by adding black conductive carbon pills. It is usually used in instrument equipment, POS machines, remote controls, automotive interiors, automation equipment, or other special equipment.

Communication equipment

In the communication equipment field, conductive silicone keypads serve as input devices and provide sensitive tactile feedback, letting users accurately input information and control equipment.

Household appliances

The conductive carbon pill silicone keypads are durable and stable, they can provide stable signals and are often used as switching elements in electronic products, such as players, TVs, air conditioners, etc.

Industrial control

Excellent wear resistance and water resistance make it the best choice in the field of industrial control. It is crucial for the transmission and control of various switching equipment signals.

Instrument and equipment silicone keypads

Automotive

Conductive carbon pill silicone keypads are one of the key components of automotives, such as audio and air conditioning systems. Its high-temperature resistance, durability, and ease of cleaning make silicone buttons suitable for use in the ever-changing automotive interior environment.

Design and specifications of conductive carbon pills

Conductive carbon pills are generally designed in round, square, or oval shapes, and can be designed and customized according to your needs. The diameter of circular conductive carbon pills is usually 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm,6mm,7mm,8mm.

Advantages of conductive black pills silicone keypads

Conductive black pill silicone keypads have many unique properties, making them an excellent choice for manufacturing conductive buttons.

Silicone keypads have excellent electrical conductivity and can transmit electrical signals.

Silicone has good elasticity, giving the keys a soft touch and providing users with a comfortable operating experience. Even long-term operation will not cause damage to the circuit under the keys.

Due to the excellent durability and chemical stability of conductive carbon pill silicone keypads, they have a long service life, which means the time and cost of repairing equipment and replacing parts can be saved.

Three commonly used processes for customizing legends on conductive carbon pill silicone keypads

Custom screen printing: Conductive carbon pill silicone keypads cover specific areas with ink through screen printing equipment.

Custom laser engraving: After the silicone is formed, it is first sprayed with color oil, and then a laser beam is used to carve text and various patterns on the surface of the silicone keypad to achieve light transmission of the legends.

Makes the legend on the silicone molding's surface: During the CNC mold manufacturing process, the legend is engraved directly on the mold. After the silicone is formed, it is first sprayed with color oil, and then a laser beam is used to carve text and various patterns on the surface of the silicone button to achieve light transmission of the characters.

How are conductive black pills installed on silicone keypads?

Since the installation process after silicone molding is very complicated, we usually place conductive black pills on the mold during the molding process, finally, they can be directly pressed with the silicone rubber keypads to form a solid whole. The specific details of the installation method of conductive black pills for silicone keypads are as follows:

First: Reserve the position of conductive black particles during the mold-making process.

Second: In the installation process, use the black grain jig to install the black grains.

Third: Put the jig containing black pills into the mold cavity together.

Fourth: After high-temperature vulcanization, the carbon pills or black pills will firmly adhere to the contacts of the silicone keypads.

The process of custom conductive carbon pill silicone keypads

1. After receiving the customer's drawing file, the complete design drawing file will be sent to the customer's engineer via email for confirmation. If the customer does not have complete drawings, our engineering designers can customize the design based on the customer's available information or specific requirements.

2. Confirm the keypad's structure and process with the customer engineer, and confirm the final product drawing.

3. Start sample production according to the drawings confirmed by the customer. The sample cycle for this type of keypad is generally 5-7 days.

4. After the sample has been functionally tested and approved by the customer, the mass-production mold will be developed. The mold opening cycle depends on the silicone keypad image file structure and production process, usually 10-25 days.

5. Place the conductive black pills into the mold through the black particle suction cup, and then perform molding.

6. Next, carry out inspection and packaging of finished products.
