Abstract

Reliability of electrical connections of a Low Temperature Co-fired Ceramics (LTCC) device is always a challenge. LTCC base plates are fabricated, over which a device or a sensor can be placed. Vias punched at the corners allows the provision for the electrical connection to the sensor. Conductive PdAg lines printed over the surface can be used to join the sensor part with the base plate using brazing technique. Cost of fabrication is lowered by punching the cavities using a zig fixture.

Abstract

Technological development and its commercialization are the prime factors for all-round development of any nation. The management of technology development along with its business and commercial exploitation are key areas to be identified and properly understood to remain competitive in this global market. Some technologies are partially commercialized due to improper technology management and one such example is sinter-forging or powder metallurgy forging (PMF). The technique combines advantages associated with two well-known techniques i.e. powder metallurgy and conventional forging and uses pressed and sintered metal powder performs as starting material. It is well suited for mass production of precision, net shape and high-performance components virtually without scrap loss at competitive rates. The authors have carried extensive research in this area and it is their firm believe that the technique may emerge as an advanced progressive manufacturing technology. The present paper highlights its techno-economic aspects and suggests possible research areas requiring proper management.
