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 is required to drill, bore mode in the prior art, is that pcb board is laminated
Afterwards, it is placed on backing plate and directly drills, this bore mode will produce burr, burr, or even cause to pull in hole.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of laminated construction in PTFE high frequencies twist drill hole, should
Structure makes the burr of wiring board and burr reduce, and hole wall is avoided to pull.
Technical solution adopted by the utility model to solve its technical problems is：A kind of lamination knot in PTFE high frequencies twist drill hole
Structure thes improvement is that：Including aluminium flake, the first phenolic board, the second phenolic board, sheeting caps and multilayer line hole to be drilled
Plate；
Multilayer circuit board phase poststack successively, forms pcb layer hole to be drilled；The pcb layer is located at the
Between one phenolic board and the second phenolic board, and the upper surface of pcb layer is close to the lower surface of the first phenolic board, pcb layer
Lower surface be close to the upper surface of the second phenolic board；
Second phenolic board is arranged above sheeting caps, and the aluminium flake is arranged in the upper of first phenolic board
Side.
In such a configuration, three sandwich circuits being stacked successively are provided between first phenolic board and the second phenolic board
Plate.
In such a configuration, the thickness of the wiring board is 0.9-1mm.
In such a configuration, the thickness of the wiring board is 0.8mm.
In such a configuration, the length of the aluminium flake and the length of sheeting caps be more than the first phenolic board, pcb layer with
And second phenolic board length.
The utility model has the beneficial effects that：Due to the presence of the first phenolic board and the second phenolic board, passing through drill bit pair
When the wiring board of multilayer is drilled, it can be very good to reduce burr and burr, to avoid the hole wall of drilling from pulling, carry
The quality of height drilling.
