Abstract
Abstract A method and arrangement for the positioning and bonding of a solid body (2), in which one part of the solid body (2) together with the bonding agent (6) is to be attached to a further element (7) and bonded to a base (4) is to be capable of positioning the solid body (2), at the point attained from positioning, with both high precision and high long term stability. The solid body (2) is immersed in the bonding agent (6) and this bonding agent is in turn located in a groove of a further electrically conducting body (7). The further body (7) is heated by current flow to a temperature at which the solid body (2) is movable within the bonding agent. Upon attaining the desired positioning of the solid body (2), the bonding agent is allowed to cool through controlled reduction of the heating current until solidification occurs.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
166 words
A method for positioning and mounting a solid body in which a portion of the solid body together with a bonding agent is arranged on a further body and bonded to a support base the further body including a groove and adapted to supply heat energy, position the solid body, and contain the bonding agent; the method comprising: at least partially immersing the solid body in the bonding agent contained by the further body; supplying heat energy from the further body such that the solid body and the further body can be moved individually or in relation to each other while contacted by the bonding agent; aligning the solid body with the further body with the aid of the groove of the further body; positioning the solid body in a location relative to the support base; and cooling the bonding agent by controlling a reduction in the supply of heat energy from the further body such that the solid body is bonded to the support base.
Claim 2
Independent Claim
166 words
A method for positioning and mounting a solid body in which a portion of the solid body together with a bonding agent is arranged on a further body and bonded to a support base the further body including a groove and adapted to supply heat energy, position the solid body, and contain the bonding agent; the method comprising: at least partially immersing the solid body in the bonding agent contained by the further body; supplying heat energy from the further body such that the solid body and the further body can be moved individually or in relation to each other while contacted by the bonding agent; aligning the solid body with the further body with the aid of the groove of the further body; positioning the solid body in a location relative to the support base; and cooling the bonding agent by controlling a reduction in the supply of heat energy from the further body such that the solid body is bonded to the support base.
