2, after being completed, pcb board bag 160 to be pressed is put into each pressing chamber 154b medium to be pressed；

3, the door-plate 132 of control system control room door 130 falls, and closes pressing room 110, and air extractor starts pressing room The inner space of 110 is evacuated environment；

4, the drive end of the hydraulic cylinder 121 of hydraulic means 120 is started working, and applies certain pressure under backing plate 152, Thus promote undermost force fit plate 154 to start the pcb board bag 160 to be pressed extruding in the 154b of pressing chamber successively, same with this Time, Electromagnetic Heating assembly and Copper Foil heating assembly are started working, and heat pcb board bag 160 to be pressed, in pressing process Pressure size, temperature height, the press time carried out feedback regulation by control system；

5, after having suppressed, Electromagnetic Heating assembly and Copper Foil heating assembly quit work, and now, hydraulic means 120 keeps Pressure during compacting is constant, and cools down assembly and start working, such as, can be passed through in the cooling tube 154c in force fit plate 154 and continue Flowing, temperature control the conduction liquid between 15 DEG C ~ 35 DEG C, the pcb board bag 160 suppressed is cooled down, this process by Control system carries out feedback regulation, when control system detects that pcb board bag 160 is cooled to design temperature 45 DEG C ~ 65 DEG C, stops The supply of conduction liquid, hydraulic means 120 starts to be gradually reduced pressure, and the pcb board bag 160 suppressed is taken after opening by room door 130 Go out to wait follow-up processing work.

With reference to Figure 21 and Figure 22, it can be seen that traditional cold press and the pcb board according to composite heating of the present utility model are many Cavity layer press 100 compares, same measurement X-Y direction (500 ~ 620mm distance) harmomegathus data, composite heating of the present utility model The product that pcb board multi-cavity laminating machine 100 produces, the deflection of upper, middle and lower layer product is almost consistent, and contrast traditional cold press has non- The most significantly improve, additionally, due to after having colded pressing, the temperature of force fit plate 154 directly drops to the temperature that technique needs, and directly may be used To start next group production, it is not necessary to extra cool time, device efficiency is high, further increases production efficiency.

With reference to Figure 23 and Figure 24, take 350 sheet measurement X-Y direction (500 ~ 620mm distance) harmomegathus data and add up, can To find out, according to the pcb board multi-cavity laminating machine 100 of composite heating of the present utility model compared with traditional cold press, this practicality is new Its harmomegathus data of product that the pcb board multi-cavity laminating machine 100 of the composite heating of type produces substantially are concentrated, and produce than traditional cold press Product harmomegathus rate reduced 30 ~ 40%.

With reference to Figure 25, Figure 26, Figure 27 and Figure 28, it can be seen that according to the pcb board multi-cavity of composite heating of the present utility model Laminating machine 100 is compared with traditional cold press, according to being given birth to of the pcb board multi-cavity laminating machine 100 of composite heating of the present utility model The monolithic PCB expansion maximum distortion produced reduces 40 ~ 50% than what conventional voltage machine produced.

Although embodiment of the present utility model is disclosed as above, but it is not limited in institute in description and embodiment Row use, and it can be applied to various applicable field of the present utility model completely, for those skilled in the art, and can It is easily achieved other amendment, therefore under the general concept limited without departing substantially from claim and equivalency range, this practicality Novel be not limited to specific details and shown here as with describe legend.
