Isostatic (hydraulic) pressing with a warm temperature haslaminated ceramics green sheets in multilayer electric components suchas IC packages, capacitors, etc. in more uniform and higher density thanother methods such as mechanical presses. This results in higherthroughput because the deviated or low density of laminated green sheetsmay cause delamination and uneven shrinkage in the sintering process.Isostatic pressing, however, has two problems due to the wet bagprocess. 1. Vapor generation - during heating up, binder and plasticizerin the sheets inside a bag are vaporized and the vapor is collected inthe bag which may aggravate the uniformity of the laminating pressure onthe sheets. 2. Automation - the operation may not be fully automated dueto the handling of a wet bag. This paper introduces the essentialsolution for these two remaining problems
