The specific embodiment
Figure 1A is the constructed profile of the laminated plate green compact of one embodiment of the present invention; Figure 1B is the schematic cross sectional view of the composite laminated plate 2 that forms after 1 heat treatment of laminated plate green compact.
Sintering laminated plate 1 does not comprise first lamella 4 and two second lamellas 6 that contain ceramic particle 5 that contain glass powder 3.Two second lamellas 6 all contact with first lamella 4.Because two second lamellas 6 are clamped first lamella 4 in this embodiment, so two first type surfaces of laminated plate green compact 1 are provided by these two second lamellas 6.
The preferred glass material of glass powder 3 is anorthite glass ceramicses in first lamella.The example of another kind of glass material comprises borosilicate glass and cordierite glass ceramics.The granularity of glass powder 3 needn't be little as the granularity of ceramic particle 5, and can be bigger than the granularity of ceramic particle 5.
The example of useful decentralized medium is water, toluene, alcohol and composition thereof.The example of adhesive is butyral resin, acrylic resin, polyurethane resin, vinyl acetate resin and polyvinyl alcohol.If desired, slurry can contain plasticizer, dispersant and defoamer.Green sheet can form by extruding, roll-in or compacting.
After first lamella 4 was made separately as mentioned above, second lamella 6 just can be formed on this sheet.In this case, preparation earlier contains the slurry of ceramic particle 5, dispersant and adhesive, will immerse in the slurry as the sheet of first lamella 4.This immersion processes can be made effectively and comprise the laminated plate green compact 1 that are provided at 4 two lip-deep second lamellas 6 of first lamella.Regulate content and the Immersion time of ceramic particle 5 in slurry, just can control the thickness of second lamella 6.
In the slurry of second lamella 6, in Figure 1A and 1B, be shown as the adhesive and the dispersant of carrier 8, can be identical with adhesive and the dispersant in first lamella, 4 slurries, also can be different.

Before the heat treatment, laminated plate green compact 1 should be suppressed on stacked direction.In heat treatment step, the temperature of employing should not cause ceramic particle 5 sintering but make glass powder 3 fusings.In heat treatment step, the carrier 8 in the carrier 7 in first lamella 4 and second lamella 6 is removed, and the glass powder 3 in first lamella 4 is fused into glass melt, is bonded into first lamella 4, shown in Figure 1B.In addition, a part of glass melt 9 infiltrates in second lamella 6 by capillary force, enters the gap between the ceramic particle 5, and ceramic particle 5 is bonded to each other.
The surface roughness of two first type surfaces of formed composite laminated plate 2 depends on the granularity of the ceramic particle 5 in second lamella 6.Therefore, even when the granularity of glass powder 3 is big, use undersized ceramic particle 5, also can reduce the surface roughness of composite laminated plate 2.
The size of the ceramic particle 5 in second lamella 6 is more little, and the ceramic particle 5 in second lamella 6 is just intensive more.In this case, cause that the capillary force of glass melt 9 generation VISCOUS FLOW is just big more, glass melt 9 will be more intensive.
In addition, glass melt 9 can arrive the outer surface of second lamella 6, and its surface tension can make this smooth outer surface.Therefore, glass melt 9 also helps to improve the smoothness of two first type surfaces of composite laminated plate 2.

Aspect granularity and material, ceramic packing 10 can be identical with the ceramic particle 5 in being contained in second lamella 6, also can be different.
Other structures and manufacture method shown in Fig. 2 A and the 2B in second embodiment are identical with the embodiment shown in Figure 1A and the 1B basically.
Because the first lamella 4a contains ceramic packing 10, so formed composite laminated plate 2a has bigger mechanical strength.
In the composite laminated plate 2a shown in the composite laminated plate shown in Figure 1A and the 1B 2 and Fig. 2 A and the 2B, make second lamella 6 of smooth surface on composite laminate beyond the region of objective existence limit by using tiny ceramic particle 5.As composite laminated plate 2 or 2a during as circuit board, the outer conducting film with fine pattern just can be formed on its first type surface no problemly, the high-density line of formation circuit board.
Composite laminated plate 2 or 2a can comprise inner conductor, for example inner conductive film and also at the perforation contact of inside.

The glass powder that is contained in first lamella is the anorthite glass ceramics, and granularity is about 6.50 microns in embodiment 1-4, and granularity is about 3.63 to 7.47 microns in Comparative Examples 1-4.First lamella in the Comparative Examples 5 does not contain glass powder.
In all composite plates, first lamella all contains the Powdered aluminium oxide that granularity is about 0.35 micron, as ceramic packing.
Glass powder and ceramic packing mix with 60: 40 part by weight.In embodiment 1-4 and Comparative Examples 1-4, water joins in the mixture as adhesive as dispersant, butyral resin, and water and butyral resin then join in Comparative Examples 5 in the ceramic packing, forms slurry.Remove the bubble in the slurry, form green sheet with the scraping blade method, making dry thickness is 500 microns.

Table 1 shows that every surface roughness Ra with plate of second lamella all is positioned at the 0.17-0.48 micrometer range.Surface roughness Ra depends on the granularity of ceramic powders in second lamella, and when promptly the granularity of ceramic powders reduced, surface flatness increased.
With compare except 0.8 micron the surface roughness Ra that does not form second lamella, Comparative Examples 3 that other preparation condition is identical, the surface roughness Ra among the embodiment 1-4 obviously descends.
Relatively Comparative Examples 1-4 as seen, when the granularity of glass powder reduces, surface roughness just descends.Yet shown in Comparative Examples 1, the granularity of glass powder must be decreased to about 3.63 microns, just can obtain to be comparable to the surface roughness of embodiment 1-4.So little granularity is actually unpractical, because it is very high to prepare the production cost of thin glass powder.
When not forming second lamella on first lamella that only contains ceramic packing, shown in Comparative Examples 5, surface roughness Ra is 0.20 micron, and so little surface roughness is satisfactory.Yet in this case, heat treatment temperature must be increased to 1500 ℃.Therefore, can just be restricted as the metal of internal conductive film 19-24 and perforation contact 25-30.So little surface roughness can be by for example the ceramic powders granularity in second lamella being decreased to 0.35 micron and easily obtain, shown in embodiment 1.
The present invention can comprise the various variations to the above-mentioned embodiment of reference accompanying drawing and table 1 illustrated embodiment.
The number of first and second lamellas and stacked order thereof can change according to designing requirement, as long as each second lamella all contacts with each first lamella, and second lamella will constitute at least one first type surface of composite laminated plate.
First lamella can have thickness arbitrarily.Second lamella also can have thickness arbitrarily, as long as the glass melt in first lamella can partly infiltrate in second lamella, thereby makes the ceramic powder particle in second lamella can be bonded to one another.
The green sheet of first lamella can contain glass fibre, glass whisker, glass flake or glass platelet, is used for replacing glass powder.
The present invention also can be applicable to have on the outer surface the composite laminated plate in the hole of opening.These holes are formed in the composite laminated plate green compact, and when the composite laminated plate of making was used as multilayer circuit board, these holes were used for fixing electronic component.
