Impedance matching FPCs

Impedance matching FPCs

Optimum for high speed transmission and improved equipment performance

Along with the appearance of high speed transmission circuits in recent years, characteristic impedance is becoming increasingly important.
Oki Electric Cable can perform characteristic impedance matching by appropriately combining conductor width, distance between conductors, material thickness, and type of material.

Earth friendly FPCs

Earth friendly FPCs

We offer environmentally friendly FPCs.

In recent years, we have been engaged in environmental issues in our overall lifestyle.
We have a lineup of low outgassing FPCs which meet RoHS and can be used even in a vacuum, as environmentally friendly products.

1. FPCs that meet RoHS

We now offer products made by gold plating and the use of lead-free solder instead of the conventional leaded solder. Particularly, we use our own facilities for gold plating, so we can control and guarantee the quality of the entire FPC process.

2. Liquid crystal polymer material FPCs

Liquid crystal polymer is a generic term for wholly aromatic polyester polymers.

Features
  1. Highfrequency electrical characteristics (low dielectric constant, low dielectric dissipation factor)
    High speed transmission is possible
  2. Water absorption resistance (approx. 40 times that of polyimide)
    ---Can be used in a location where it is exposed to water or moisture.
  3. Low outgassing performance (0.03WVR%)
    ---Can be used in a vacuum.
  4. Flame retardant, chemical resistance, etc.
Basic specifications

Long FPCs

Long FPCs

Light, multi-wiring module for large equipment

We can make FPCs10 m long without joints Particularly, these long flexible FPCs feature thinness, lightness and softness, making them suitable for multiple wiring in large equipment.
Because there are no joints, the FPC remains electrically stable in applications where it is flexed.

Layerconfiguration Single-sided FPCs
FPC length to 10000mm
Layer thickness (flexible part) 140µm (catalog value)
Base material
(copper clad laminate)
Copper foil 35µm
Polyimide 25µm
Cover layer Polyimide 35µm
Line/Space 300/300µm
Hole diameter 300µm
Surface finish Ni-Au plating
Chemical treatment
Rainforcing plate Glass epoxy 1.6mm >
Polyimide 125µm
Configuraion 2 to 5 single-sided boards (pin connectorsoldered connections)
Bendability At least 20 million times (Differs dependingupon the bending conditions)
UL UL796, UL796F

Multi-layer FPCs

Multi-layer FPCs

Optimum for multi-wiring in light, short and small equipment

High function is being demanded along with the increasingthinness and compactness of equipment and products in recent years. Amulti-layer FPC can be wired in confined spaces. Because it is of a multi-layerconstruction, it is ideal for multi-wiring. Multi-layer FPCs can be produced invarious configurations.
Oki Electric Cable makes optimum proposals to customers fromseveral kinds of configuration patterns.

Layerconfiguration 4 layers
Overall thickness > 250µm
Base material Polyimide 2-layer material, 3-layer material
Cover layer Polyimide
Solder resist
Line/space 75/75 µm
Hole diameter > 300µm
Surface finish Ni-Au plating
Heat resistant preflux
UL Possible

Flex-rigid board

Flex-rigid board

Integration of flexible PC and rigid PC board

We have combined the softness of the FPC with the mounting stability of a rigid PC board. the resulting connector-less assembly (the cost of components and the work of purchasing and managing them are rendered unnecessary) enables man-hours to be reduced.
Also, because the flex-rigid board is integrated by means of through holes, it features high electrical reliability.

Configuration 4layers Flex-rigid board
  Inner-layer: One double-sided FPC
  Surface-layer: Two single-sided rigid board
6layers Flex-rigid board
  Inner-layer: Two double-sided FPC
  Surface-layer: Two single-sided rigid board
Max. dimensions 210x445mm
Board thickness 0.6t to 1.6t
Min. line width 0.12mm
Space 0.12mm
Min.hole diameter φ0.3mm
