Technical field

The utility model relates to PTFE high frequency dual platens.

Background technique

Dual platen is the two-sided printed circuit board for being all covered with copper for including top layer and bottom, is most common and most general electricity There is conductive pattern on road plate, the two sides of insulating substrate, and the electrical connection on two sides mainly passes through via hole or pad is attached, because For two sides can cabling, greatly reduce the difficulty of wiring, therefore be widely adopted.

Existing PTFE is the English abbreviation of polytetrafluoroethylene (PTFE), has fine toughness and insulating properties, existing PTFE high frequency Dual platen after outer PTFE layers of the side bonds of layers of copper using pressing, and existing shortcoming has: this dual platen actual strength is not It is enough, it is easy to be broken under external force.

Utility model content

The purpose of this utility model is to provide PTFE high frequency dual platens, to solve entirety mentioned above in the background art The not high problem of intensity.

To achieve the above object, the utility model provides the following technical solutions: PTFE high frequency dual platen, including substrate, institute It states and is printed with printed circuit on substrate, the inner end of the printed circuit is installed with copper post, is equipped with circular hole, the copper in the substrate Column is inserted into circular hole, includes layers of copper, aluminium foil, Polycarbonate Layer, rock wool fibers layer and PTFE insulating layer, institute inside the substrate The outer surface adhered aluminium foil of layers of copper is stated, the outer surface of the aluminium foil is pasted with rock wool fibers layer, the appearance of the rock wool fibers layer Bread wraps up in PTFE insulating layer.

Preferably, the layers of copper with a thickness of 1 millimeter, aluminium foil with a thickness of 0.3 millimeter.

Preferably, the inner surface of the outer surface bonding Polycarbonate Layer of the aluminium foil, the outer end face of Polycarbonate Layer are viscous Connect the inner surface of rock wool fibers layer.

Compared with prior art, the utility model has the beneficial effects that layers of copper and aluminium foil have good thermal conductivity, can incite somebody to action Heat derives inside substrate, and aluminium foil is with respect to layers of copper, ductility is more preferable, not easy to break in the bent state, aluminium foil it is outer Surface is bonded the inner surface of Polycarbonate Layer, and Polycarbonate Layer itself has the characteristics that intensity is high, hardness is big, unpliant, makes It is more preferable to obtain side intensity in substrate, protects layers of copper and aluminium foil, the outer end face of Polycarbonate Layer is bonded the inner surface of rock wool fibers layer, The outer surface for being attached to Polycarbonate Layer is taken off by the fiber of rock wool fibers layer, is increased the resistance to fracture of Polycarbonate Layer, is then made It is higher to obtain monolith substrate intensity, solves the problems, such as that integral strength is not high.
