FR4 Automotive Potentiometer Complex Carbon PCB

Carbon PCB is one kind of our PCB boards, and is widely used in many products such as auto parts including air conditioning, seat adjustment, rear view mirror, wiper and so on; power tools accessories like electric drill; game pad like PS2, XBOX360. This type of carbon PCB is used for automotive potentiometer. We make our carbon PCB with high-end imported carbon film, which has very long lifetime. There are mainly single-side and double-side carbon PCB.

Our Carbon PCB Specification of potentiometer

Material: FR-4 & carbon complex, the outer carbon circle operates as a resistor. The resistance value is adjusted by the carbon layer composition. The wiper of the potentiometer shorts the inner carbon circle and outer carbon circle. The value of resistor is also adjusted by the carbon layer composition. The resistance plate is connected through three holes with rivets. The resistance value is given by the carbon layer and minimized on areas with very little resistance values through silver layer.        

Board thickness: 0,6mm ±0,08mm, leading to a minimum value of 0,52mm and a maximum value of 0,68mm.

Carbon value: 3.7Kohm+/-20%           

Carbon life: 100,000 times

FAQ

1.Are you a factory or trade company?

A. Xing Da Electric Technology Company is a manufacturer with PCB factory and PCB Assembly factory.


2.Which types of PCB are you expert in?

A. We are specialized in producing Multilayer PCB,HDI board,HDI PCB,FPC Flex-Rigid,HDI Flex-Rigid board,Heavy copper PCB,Heavy gold PCB,Impedance control board,High TG PCB,Rogers PCB,half-hole, double-sided, single-sided, etc.


3. What is your testing policy and how you control the quality?

A. We test samples by flying probe; for PCB Volume over 3 square meters, usually tested by fixture, this will be more faster. As there are many steps of PCB production, we do inspection after every step.


4. Are my PCB files safe when I submit them to you for manufacturing?

A:We respect customer's copyright and will never manufacture PCB for someone else with your files. We can sign NDA with you.
