22 Pin 0.5mm Pitch Reverse FPC-to-FPC Fine Coaxial Cable Assembly for LCD Display Modules

Product Details

22 Pin 0.5mm Pitch Reverse FPC-to-FPC Fine Coaxial Cable Assembly

HOTTEN provides custom 22-pin 0.5mm pitch reverse FPC-to-FPC fine coaxial cable assemblies for compact LCD display modules and other high-density electronic applications.

This cable assembly combines fine coaxial wire construction with FPC-to-FPC interfaces, providing a compact interconnect solution where conventional larger cable structures may require too much routing space.

The reference design uses a 22-pin, 0.5mm pitch reverse FPC-to-FPC connection. The finished assembly can be customized according to the customer's FPC specification, cable structure, cable length, pinout, routing requirements, connector/interface design, and application.

HOTTEN's core manufacturing capability is fine electronic wire and micro coaxial cable production. FPCs, connectors, PCB interfaces, housings, and other components can be integrated according to customer drawings, BOMs, samples, and engineering requirements.

Engineering Considerations

The main value of this assembly is the combination of fine coaxial cable and a compact FPC-to-FPC interface.

If the display module has limited routing space around the interface, then a reverse FPC-to-FPC assembly can simplify the physical connection, because the interface orientation can be matched to the available PCB and module layout.

If the application requires separated or shielded signal paths, then fine coaxial construction can be considered, because each signal path can be constructed with its own surrounding conductive structure where required.

FPC-to-FPC Hybrid Interconnect

Unlike a standard cable with two conventional connector ends, this assembly is designed around an FPC-to-FPC interface architecture.

Potential system structures include:

FPC → fine coaxial cable → FPC

or, depending on the customer's design:

PCB / module → FPC → fine coaxial cable → FPC → display module

This allows the fine coaxial section to bridge two compact electronic interfaces while keeping the overall cable assembly adapted to the device's routing geometry.

If the system has separate FPC interfaces on two modules, then an FPC-to-FPC fine coaxial assembly can be customized around those interfaces, because the cable geometry and termination can follow the actual mechanical layout.

Why Use Fine Coaxial Cable in an FPC-to-FPC Assembly?

FPCs provide a compact and flexible interface, while fine coaxial cable can provide a different signal-routing structure between the two interfaces.

This can be useful when the design requires:

• Compact routing
• High signal density
• Controlled signal separation
• Flexible three-dimensional routing
• Customized cable length
• Small connection space

If the application requires a cable route that cannot be easily achieved with a single flat-FPC structure, then a fine coaxial section can provide an alternative interconnect architecture, because individual fine wires can be routed through a three-dimensional path before terminating into the required FPC interfaces.

Reverse FPC Interface

The reverse FPC configuration should be defined according to the actual mating direction and contact orientation required by the customer's device.

Before production, OEM engineers should confirm:

• Contact side
• FPC orientation
• Pin numbering
• Mating direction
• Interface dimensions
• Bend direction
• Available clearance
• Required insertion length

If the contact side or FPC orientation is incorrectly defined, then the assembly may not mate correctly even when the pin count and pitch are correct, because reverse FPC configurations depend on physical contact orientation as well as electrical pin assignment.

For this reason, the FPC drawing or sample should be supplied during RFQ whenever available.

Customer-Specified Components and Assembly

HOTTEN's core advantage is fine electronic wire and micro coaxial cable manufacturing.

The FPC itself, along with connectors, PCB boards, housings, and other components, can be specified by the customer.

Customers can provide:

• FPC drawing
• FPC part number
• Connector / mating interface information
• Pinout
• Cable assembly drawing
• Cable length
• Mechanical routing requirements
• PCB information
• Housing information
• BOM
• Sample

HOTTEN can then coordinate:

fine-wire / micro coaxial cable → cable preparation → precision termination → FPC integration → shielding / protection → inspection → finished cable assembly

This allows the customer to source a complete finished assembly rather than purchasing fine coaxial cable and arranging separate assembly processes.

OEM Customization

Procurement Information

For an accurate quotation, OEM customers should provide:

FPC drawing + pinout + mating direction + cable length + cable construction + cable OD + application + annual quantity

For a complete assembly, also provide:

BOM + 2D / 3D assembly drawing + PCB information + housing information + testing requirements

The FPC orientation and contact-side information are especially important for this product.

If the customer does not yet have a final cable construction, then provide the two mating interfaces, pinout, available routing space, required length, and signal requirements, because these inputs allow HOTTEN to evaluate the appropriate fine coaxial construction.

Quality and Testing

Depending on the project requirements, the finished assembly can be evaluated through:

If the assembly is used in a high-speed display or imaging system, then the final cable assembly should be evaluated against the actual system requirements, because cable performance depends on both the fine coaxial section and the FPC/interface transitions.

Why Choose HOTTEN

HOTTEN focuses on fine electronic wire, ultra-fine micro coaxial cable, precision processing, and finished cable assembly manufacturing.

For this FPC-to-FPC assembly, the production chain can include:

Ultra-fine wire manufacturing → fine coaxial cable construction → cable preparation → precision termination → FPC integration → inspection → finished cable assembly

The FPC, connector, PCB, or housing does not need to be an HOTTEN-manufactured standard product. Where specified by the customer, HOTTEN can integrate the required components according to the customer's drawing, BOM, part number, or sample.

The final deliverable is therefore a complete custom cable assembly, rather than a standalone fine wire product.

FAQ

What is the interface of this cable assembly?

The reference design uses a 22-pin reverse FPC-to-FPC interface with 0.5mm pitch.

What does reverse FPC-to-FPC mean?

It refers to the orientation of the FPC contact/interface arrangement. The exact contact side and mating direction should be confirmed from the customer's drawing or sample before production.

Can the cable length be customized?

Yes. Finished cable length, tolerance, routing, cable construction, and other mechanical parameters can be customized.

Can HOTTEN supply the FPC?

The core HOTTEN manufacturing capability is fine electronic wire and micro coaxial cable. The FPC can be customer-specified and integrated into the finished assembly according to the required drawing, part number, BOM, or sample.

Can the product be used for LCD displays?

Yes. The referenced structure is suitable for LCD display modules and compact display electronics, subject to the electrical and mechanical requirements of the specific application.

Can HOTTEN integrate the assembly with PCB or housing components?

Yes. When required by the customer design, HOTTEN can integrate the fine cable with FPC, PCB, specified connectors, housing, and other components into a finished assembly.

What information is needed for an RFQ?

The most important information includes FPC drawings, pinout, contact orientation, pitch, cable length, cable OD, signal requirements, BOM, application, annual quantity, and testing requirements.
