Why does touch screen's FPC often need to be customized?

Shenzhen Xinlilai Touch has been deeply involved in the field of PCAP touch screen for many years, and knows that "standard products" cannot meet all needs. Especially on PCAP touch screen'S FPC, different device designs often require different "dedicated channels". Today, let's talk about the importance of customized cable layout.
 

Why do cables often need to be customized? Because devices vary greatly:
Different sizes and shapes: mobile phones, tablets, industrial control devices, medical instruments, smart homes The internal spatial layout of the equipment is vastly different. The length, width, bending position, and angle of the touch screen ribbon cable need to be accurately matched with the "skeleton" of the device.
 

The interface position should be "aligned": the connector position on the motherboard and the interface position of the touch screen itself may vary in different projects. The type, number of PINs, spacing, and relative position of the connectors at both ends of the ribbon cable (such as ZIF, Board to Board) need to be customized in order to perfectly "bridge" the ribbon cable.
 

Special environments have "requirements": Some PCAP touch screen devices may operate in environments with high humidity, high temperature, high vibration, or require special shielding (EMI). At this point, the wiring needs to use higher specification materials (such as PI with higher TG values and reinforced shielding layers), special covering films, or reinforced rib designs to meet stringent requirements.
 

The routing path needs to be "optimized": In order to avoid internal components, screws, or achieve better signal integrity, the routing path and number of layers (single-layer/double-layer/multi-layer) of the ribbon cable may need to be specially designed.
 

The customization level of a seemingly simple cable often directly affects the assembly efficiency, internal space utilization, and reliability of the final product of the entire machine. Choosing a source factory with deep customization capabilities for cooperation can make your equipment design more effortless and performance more stable and outstanding.
