Embodiment Construction
[0010] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0011] Such as figure 1 The production equipment of a polytetrafluoroethylene adhesive sheet shown includes a rotary uncoiler, a cloth splicing machine, a cloth accumulator, a front tractor, a dipping machine, an oven, an EPC edge correcting machine, a rear tractor, a cutting Edge machines and winders.
[0012] Operation process of the present invention:
[0013] In the uncoiling section, the machine can operate continuously through the combination of rotary uncoiler, fabric splicer and fabric accumulator. The cloth accumulator stores enough raw cloth so that the rotary uncoiler can perform cloth joining on the cloth joining platform when it stops. During ...

The invention relates to the technical field of circuit boards, and especially relates to a production device of a PTFE bonding sheet. The production device comprises a rotary uncoiler, a cloth receiving machine, a cloth storage machine, a front tractor, an impregnation machine, an oven, an EPC edge correction machine, a rear tractor, an edge trimmer and a winder, a raw material reaches the cloth receiving machine through the rotary uncoiler and enters the cloth storage machine, the cloth storage machine stores enough raw material and then sends the material to the impregnation machine through the front tractor, and the material goes through the oven, enters the PEC edge correction machine, goes through the rear tractor, enters the edge trimmer and finally enters the winder. The production device is simple, improves the shortages of present PTFE glass cloth coated copper sheets in China, changes a present situation that present Chinese high-frequency microwave substrates are mainly imported, and satisfies demands on the social highly-informative development and the information processing high-speed development of Chinese aviation, spaceflight, mobile telephone receiving base stations and the like.
