It is noted that the pressure transmission reinforced laminate structure after this optimization, tool are with the following changes:
One: respectively increasing by ten brown paper b in head and the tail, as shown in layer laminate 1 lower in Fig. 2 and top laminate 3.It can not only be to production
Product play the role of a buffering when pressing pressurization, moreover it is possible to transmit the heat between each level of product relatively uniform, because of pressure
Machine be pass through upper and lower heated plate simultaneously heating heating is carried out to entire lamination, so as to preferably avoid product pressing when most
Bottom and top layer are too fast in the product among lamination because being heated, and layer of PVC f packing material melts relatively too fast
And displacement is generated so as to cause product wrinkle.
Two: due to the particularity in product reinforcing face, being further added by two oxen on the basis of product reinforcing surface and PVC packing material
Mulberry paper b, as shown in Fig. 2 product layer laminate 2.Since common product surface is relatively flat, and reinforcement product surface is substantially all and deposits
In the different drop of height, PVC material is depended merely on sometimes and is filled and can not reach requirement, lead to fill being not enough and there are offices
Portion's pressure is not firm, at this moment by increasing by two brown paper b on the surface layer of PVC f again, so that it may increase filling effect greatly to full
Sufficient product demand.
Three: referring now to traditional symmetrical stack due to product two sides asymmetry, so need to be using asymmetric laminated construction, such as
Shown in Fig. 2 product layer laminate 2.To guarantee product compacting not wrinkle, when compacted products, product reinforcing is placed upward, is retained above
Layer of PVC f packing material, contacts with steel plate (do not need PVC packing material) directly below, in this way during pressure transmission below product
It is contacted with smooth steel plate, there is high and low fall reinforcement product to contact with layer of PVC f packing material above, can thus play product
Reinforcement is sufficient filling with compacting when suppressing, and will not generate wrinkle.
Four: increasing a single side without silicon release film g, as shown in Fig. 2 product layer laminate 2 in packing material PVC surface.For
For normal FPC product, surface is relatively flat, and mobility is smaller when in pressure transmission process, PVC is filled after melting, will not
Product is had an impact；But for compacting is with reinforcement product, product surface is substantially all the drop different in the presence of height,
Mobility is bigger when in compacting, PVC is filled after melting in this way, can thus cause displacement to generate folding to product
Wrinkle.Traditional common release film is unable to satisfy requirement, and all preferable in resistance colloidality and adhesion without silicon release film, so filling
Material PVC surface one single side of increase is big after can effectively preventing PVC from melting without silicon release film g (no silicon face is contacted with PVC)
Area flow can only be filled in subrange, product is avoided to shift.
The present invention is for traditional lamination operation, and the laminated construction after this optimization is mainly in each increase by ten of head and the tail
Brown paper is opened, for product characteristic using asymmetric laminated construction, product reinforcing face is filled using PVC+ brown paper, simultaneously
Common release film, product another side (non-benefit are substituted without silicon release film (no silicon face is contacted with PVC) in PVC surface plus a single side
Strong face) directly contacted with steel plate, be not required to plus packing material, so as to improve occur after product pressure transmission displacement, wrinkle, solve existing
There is FPC product in traditional fast pressure mode operates, the defects and limitations as existing for itself lead to FPC product same type not
It needs to reach simple process using the technological deficiency for separating the method repeatedly suppressed when stack pile reinforcement pressing, ultrahigh in efficiency
