Description
Technical field
The utility model is related to circuit board technology fields, more specifically, the utility model is related to a kind of low intermodulation phase shifts
Device slide plate circuit board.
Background technology
Pcb board, also known as printed circuit board, printed wiring board, abbreviation printed board are cut into a scale using insulation board as base material
Very little, at least attached thereon there are one conductive patterns, and are furnished with hole（Such as component hole, fastener hole, plated through-hole）, and realize electronics member
Interconnection between device.Since this plate is made of electron printing, therefore it is referred to as " printing " circuit board.
Pcb board in the prior art all includes pcb board medium and copper foil, and copper foil is thick with the contact surface of pcb board medium
Rugosity is generally all bigger, i.e. the roughness ratio of electric current transmission surface is larger, and the intermodulation index of circuit board is caused to deteriorate.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of low intermodulation phase shifter slide plate circuit board, this is low
Intermodulation phase shifter slide plate circuit board is applied when on phase shifter by the way that the smooth surface of reversed copper foil to be combined with pcb board base material,
To improve phase shifter intermodulation characteristic.
Technical solution adopted by the utility model to solve its technical problems is：A kind of low intermodulation phase shifter slide plate circuit
Plate thes improvement is that：Including pcb board base material and reversed copper foil；
There is the pcb board base material upper and lower surface, the reversed copper foil to have upper and lower surface, and anti-
It is rough surface to the upper surface of copper foil, the lower surface of reversed copper foil is smooth surface；The lower surface of the reversed copper foil and the PCB
The upper surface of plate base material is combined.
In such a configuration, the roughness RZ of the upper surface of the reversed copper foil is 0.9-1.4 um.
In such a configuration, the roughness RZ of the lower surface of the reversed copper foil is 0.5-0.9 um.
In such a configuration, the reversed copper foil is electrolytic copper foil.
The utility model has the beneficial effects that：In board production manufacturing process, always by the smooth surface of reversed copper foil
It fits with pcb board base material, to reduce the roughness of electric current transmission surface, the intermodulation index of circuit board is avoided to deteriorate；It applies and is moving
When on phase device, 10 decibels of phase shifter intermodulation characteristic or more can be improved.
