Ceramic multilayer board with monolithic layer structure and method for the production thereof |
| abstract |
A ceramic multilayer board as a monolithic multilayer composite with improved residual pore contents, lateral shrinkage, shrinkage tolerances and surface roughness is produced in a modified LTCC multilayer process, which is characterized by a two-stage or multi-stage sintering process. In order to minimize the lateral shrinkage, the composite is built up from several (≥ 3) ceramic cast foils from glass-ceramic composite powders that sinter tightly at different temperatures, the inner layers of the composite being the first to sinter and a lateral shrinkage being prevented. The glass phase of the corresponding composite material of the inner, first sintering layers crystallizes largely during or immediately after the dense sintering of these layers, as a result of which these layers become refiring-stable and remain dimensionally stable when the temperature is increased further below the melting temperature of the crystals formed. The outer layers of the composite sinter in a second stage at a higher temperature but below the melting temperature of the crystals in the inner layer. An almost pore-free, fine-grained dispersion phase / matrix structure is formed in the outer layer and a glassy skin with very low surface roughness is formed on the surface. |
