Disadvantages of Flexible PCBs (FPCs)
Flexible PCB technology, also known as FPC (Flexible Printed Circuit), has gained popularity in various electronics sectors due to its compactness, high density of electrical connections, and cost savings compared to rigid PCBs. However, FPCs do come with some drawbacks:
- High Initial Cost:
- FPCs are designed and manufactured for specialized applications, resulting in a relatively high one-time initial cost. This includes expenses related to circuit design, wiring, negatives, and molds
- Challenges in Change and Repair:
- Once an FPC is made, it’s not easy to modify. Changes require adjustments to the film drawing, making alterations cumbersome
- Size Limitations:
- FPCs are typically produced using intermittent methods, which restricts their size. They can’t be excessively long or wide
- Susceptibility to Mechanical Stress:
- Due to their thin and flexible nature, FPCs are more prone to bending, folding, or damage under improper handling. Rigid PCBs are less susceptible to mechanical stress
