Description
Technical field
The present invention relates to copper foil covered stack and printed wiring board.
Background technology
Flexible printing wiring board (FPWB:Flexible Printed Wiring Board) and printed circuit board (PCB) (PCB:
Printed Circuit Board) and their multiwiring board has been used in mobile communication equipments such as mobile phone, smart mobile phones
Or be widely used in the product such as network associated electronic device, the mainframe computer such as its base station apparatus, server/router.
In recent years, for these products, high frequency telecommunications is used to transmit/handle Large Copacity information at high speed
Number, but high-frequency signal is very easy to decay, therefore, is also required that for multiwiring board and tries to suppress transmission loss as far as possible.
There is conductor losses and dielectric substance loss in transmission loss.When the frequency of electric signal is more than GHz, conductor losses is because of kelvin effect
Surface state dependent on the copper foil used in circuit.On the other hand, Jie of the dielectric substance loss to the insulating materials of near circuitry
Electrical characteristics, particularly dielectric loss angle tangent influence are very big.
As the means for suppressing the transmission loss in multiwiring board, for example, it is contemplated that will be excellent using low dielectric property
Polyimides, the flexible copper clad foil plywood of liquid crystal polymer are used as base material (for example, see patent document 1 and 2).
But, the process that these methods need the laminating copper foil under high temperature (more than 300 DEG C) easily causes yield rate difference etc.
Problem, seeks to solve.
On the other hand, also exist copper foil covered folded obtained from the copper foil of low roughness is combined with polyimide layer
Plate come suppress from copper foil surface state conductor losses, suppress transmission loss method (for example, see patent document 3),
But the bonding process under high temperature (more than 300 DEG C) is stilled need when copper foil is fitted, easily causes the problems such as yield rate is poor, solution is sought
Certainly.
In addition, from the viewpoint of impedance control, the dielectric constant of preferred insulative material is relatively low.That is, the resistance of transmission circuit
Anti- (Z0) determined by the thickness and dielectric constant, the width of circuit and thickness of insulating materials.In recent years, the film of circuit substrate
Change promote, in order to take into account impedance control and filming, it is necessary to (1) reduction insulating materials dielectric constant or (2) circuit it is thin
Membranization and thin space.But, the possibility that circuit reliability is lost in (2) is high therefore not preferred.Therefore, in expanded circuit
In the sense that the free degree of design, the requirement of dielectric materials is high.
