Abstract
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.
Description
Technical field
The present invention relates to the circuit board technology field, especially a kind of production unit of polytetrafluoroethyladhesive adhesive sheet.
Background technology
Along with the future development of electronic product to miniaturization, high frequency, digitizing, high reliability, the microwave current high-frequency multi-layer circuit board adopts epoxy resin board as adhesive sheet in the course of processing, but its kind is single, weldability is low, and dielectric loss is large, specific inductivity is high, and stability is extremely low.
Summary of the invention
The invention discloses a kind of production unit of polytetrafluoroethyladhesive adhesive sheet.
The technical solution used in the present invention is: a kind of production unit of polytetrafluoroethyladhesive adhesive sheet, comprise the rotary type Abrollhaspel, connect the cloth machine, hold the cloth machine, front haulage machine, cement dipping machine, baking oven, EPC entangle limit machine, rear haulage machine, bead cutter and winder, starting material enter and hold the cloth machine to connecing the cloth machine by the rotary type Abrollhaspel, after holding the enough starting material of cloth machine storage, by the front haulage machine material is sent into cement dipping machine, then enter EPC by baking oven and entangle the limit machine, then enter bead cutter via the rear haulage machine, enter at last winder.
Further: baking oven is divided into drying zone, cures district and sintering zone.
The invention has the beneficial effects as follows, production unit of the present invention is simple, it has not only improved the deficiency of the glass cloth coated copper coin of domestic existing PTFE, and can change the present situation of the main dependence on import of Present Domestic high frequency microwave substrate, satisfy the development of the social advanced IT application such as domestic air mail, space flight, mobile telephone reception base station, the demand of the high speed development of information processing.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.

Among the figure: 1, rotary type Abrollhaspel, 2, connect the cloth machine, 3, hold the cloth machine, 4, the front haulage machine, 5, cement dipping machine, 6, baking oven, 6-1, drying zone, cure the district at 6-2,6-3, sintering zone, 7, EPC entangles the limit machine, 8, the rear haulage machine, 9, bead cutter, 10, winder.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
The production unit of a kind of polytetrafluoroethyladhesive adhesive sheet as shown in Figure 1 comprises the rotary type Abrollhaspel, connects the cloth machine, holds the cloth machine, front haulage machine, cement dipping machine, baking oven, EPC entangle limit machine, rear haulage machine, bead cutter and winder.
Operating process of the present invention:
In the uncoiling section, via the rotary type Abrollhaspel, the combination that connects the cloth machine and hold the cloth machine is so that machine can operate continuously.Hold the cloth machine and store enough former cloth, connecing the cloth platform and connect the action of cloth when the rotary type Abrollhaspel can be stopped.Connect during the cloth, hold the cloth machine and be released to the normal machines stored glass-fiber-fabric that gets off of when running, make and do not shut down normal change of lap production completely.Glass-fiber-fabric passes through cement dipping machine, the PTFE emulsion is applied to the glass-fiber-fabric surface, fully penetrate into glass-fiber-fabric through the PTFE emulsion, then enter baking oven, drying, cure with the sintering Three regions and heat-treat, go out baking oven after, entangle limit machine and cooling through EPC again and roll and finish process of cooling, pass through two station winders by tractor and bead cutter, make the adhesive plaster with certain resin content.
The temperature distribution of three warm areas of baking oven should be set according to the requirement of adhesive plaster.The first warm area is drying zone, and Main Function is the moisture of removing in the adhesive plaster.The second warm area is for curing the district, and Main Function is the interfacial agent of removing in the adhesive plaster.Three-temperature-zone is the sintering zone, and Main Function is with the resin heating and melting.
In case of necessity, the gluing process can be carried out repeatedly, and the resin content to the adhesive plaster reaches till the requirement.
The present invention innovates by Processes and apparatus, improve the impregnating effect of polytetrafluoroethyladhesive adhesive sheet, overcome and contain the problems such as micro-bubble, the Resin adhesive impregnability is poor, leakage is soaked, glue content is inhomogeneous in the PTFE adhesive sheet that in impregnation processability, occurs, thereby make product performance more stable, have high precision specific inductivity (tolerance+0.02) and lower dielectric loss.
The present invention makes polytetrafluoroethyladhesive adhesive sheet improve the PTFE glue to the dipping of glass-fiber-fabric in the course of processing by the vacuum-latexed mode, makes the glue stable content even.
Thereby the present invention improves the effect of impregnation and the homogeneity of glue content by dipping is controlled with the high precision of resin viscosity, and the target that high precision control will reach is: the gelatin viscosity deviation is less, and viscosimetric analysis is fed back and adjusted in time.
