FR4 Carbon Film Resistor PCBs
Carbon ink can add fixed resistance, potentiometer tracks, wear contacts, sensor paths, or jumpers to an FR4 assembly when ink, copper finish, geometry, cure, contact, and measurement are specified as one route.
Route definition
What is fixed before quotation
- Base circuit
- Released FR4 copper artwork and surface finish compatible with the carbon ink interface
- Printed functions
- Fixed resistors, rotary or linear tracks, contacts, keypad pads, and selected jumpers
- Thermal route
- Low-temperature polymer cure matched to the board, ink, prior finishes, and later assembly
- Verification
- Resistance or output curve at stated conditions plus visual, adhesion, contact, or wear checks by risk

Typical programme fit
Applications we can review
- Controls, potentiometers, and human-machine interfaces
- Rotary and linear position feedback
- Keypads and wear-resistant contact areas
- Cost-sensitive printed resistor and jumper functions
Suitability and performance are confirmed from the complete assembly and validation conditions, not the application name alone.
