Abstract
The invention relates to the technical field of circuit boards, in particular to a production process of a polyfluortetraethylene fiber glass copper layer-cladding pressure plate. The production process comprises the following steps of: obtaining a bonding piece by glue mixing and sizing; cutting and overlapping the bonding piece; combining the bonding piece with a copper foil and a steel plate; automatically laminating by using a vacuum laminating machine at high temperature and high pressure; automatically decomposing; and cutting a copper-cladding foil plate to obtain the polyfluortetraethylene fiber glass copper layer-cladding pressure plate. By using the production process, the defects that the traditional microwave circuit substrate material is difficult to metallize hole and the production line has poor machinability, complex process and the like are overcome; the production process is extremely easy to cut, drill and mechanically process; the production process is greatly simplified; the defects in national traditional PTFE (Polytetrafluoroethylene) glass copper layer-cladding plate is changed; the situation that the present national high-frequency microwave substrate mainly depends import can be also changed; and the requirements for domestic aviation, space flight, mobile phone receiving base station and social high informationized and information processing high-speed development are met.

Summary of the invention
The technical problem to be solved in the present invention is: a kind of production technology of polytetrafluoroethylene (PTFE) glass fibre copper clad laminate is provided, and not high to solve the substrate that original explained hereafter comes out at the wide frequency ranges internal stability, and technical problem such as dielectric loss is bigger.
The technical solution adopted for the present invention to solve the technical problems is: a kind of production technology of polytetrafluoroethylene (PTFE) glass fibre copper clad laminate may further comprise the steps:
A, from the basin district solvent, additive, ptfe emulsion pumped into according to certain proportioning and to join the glue agitator tank, open and stir, mix the back set aside for use;
B, the adhesive for preparing is dropped into containing in the immersion trough of vertical gluing machine, the solvent that drops into proportional quantity as required is to adjust the viscosity of adhesive;
C, with glass fabric by vertical gluing machine conveying mechanism impregnation and baking railway carriage or compartment oven dry of entering vertical gluing machine in containing immersion trough, obtain adhesive sheet;
D, adhesive sheet full-automatic return wire through cut, stacked after, with Copper Foil, steel plate Automatic Combined,, disassemble automatically then by vacuum press auto-stitching under high temperature, condition of high voltage, copper coated foil plate promptly gets polytetrafluoroethylene (PTFE) glass fibre copper clad laminate after cutting.
Further, the mass percentage content of described each component of adhesive is, the ptfe emulsion of 35-90%, and the glass fabric of 10-65%, the additive of 0.5-2%, surplus is a solvent.
The invention has the beneficial effects as follows, the polytetrafluoroethylene (PTFE) glass fibre copper clad laminate that the present invention produces has extremely low dielectric constant and fissipation factor, lower thermal coefficient of expansion, machinery, electric property homogeneity and dimensional stability are good, and polytetrafluoroethylene (PTFE) is also quite stable of dielectric constant in very wide frequency range, so the scope of application is very vast.
The specific embodiment
A kind of production technology of polytetrafluoroethylene (PTFE) glass fibre copper clad laminate may further comprise the steps:
