Abstract

A solder frame is described which, due to its meander shape, satisfactorily adheres to a material whose coefficient of thermal expansion differs greatly from that of the frame. The meander shape of solder frame 1 absorbs mechanical stresses, caused by different coefficients of thermal expansion, without becoming detached from substrate 2, so that, even after several soldering, tempering or recycling steps, its adhesion is still very good. Therefore, the frame can be used to bond components which are made of the same or different materials. Material combinations that may be bonded by means of a meander-shaped solder frame are, for example, metal/ceramic, glass/metal, glass/ceramic, glass/glass.

Meander-Shaped Solder Frame

A solder frame is described which, due to its meander shape, satisfactorily adheres to a material whose coefficient of thermal expansion differs greatly from that of the frame. The meander shape of solder frame 1 absorbs mechanical stresses, caused by different coefficients of thermal expansion, without becoming detached from substrate 2, so that, even after several soldering, tempering or recycling steps, its adhesion is still very good. Therefore, the frame can be used to bond components which are made of the same or different materials. Material combinations that may be bonded by means of a meander-shaped solder frame are, for example, metal/ceramic, glass/metal, glass/ceramic, glass/glass. The meander-shaped solder frame can be screen-printed on to the substrate or be applied by vapor deposition or sputter processes, using photolithographic steps. In some cases, the meander-shaped solder frame may be replaced by a meander-shaped glass solder frame. For gluing and sealing, the respective agents can be durably applied in a meander-shaped frame.
