Abstract
Abstract The invention relates to a process for mounting in particular electronic components on a base by means of thixotropic material whereby the material is transferred to the base by dipping a die and the component in a stock and then pressing the component on the material layer thus produced whereby the dipping and/or pressing motion of the die or the component is superimposed by a vibration for liquidefying the thixotropic material.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
90 words
A process for mounting components on a base utilizing a thixotropic material, the steps of said process including: dipping said component into a stock of said thixotropic material such that at least one surface of said component has a layer of thixotropic material thereon; pressing said component against said base such that said surface of said component having said layer of thixotropic material is in contact with said base; and vibrating said thixotropic material during at least one of the above steps; whereby said component is mounted on said base.
Claim 2
Dependent Claim
90 words
A process for mounting components on a base utilizing a thixotropic material, the steps of said process including: dipping said component into a stock of said thixotropic material such that at least one surface of said component has a layer of thixotropic material thereon; pressing said component against said base such that said surface of said component having said layer of thixotropic material is in contact with said base; and vibrating said thixotropic material during at least one of the above steps; whereby said component is mounted on said base.
Claim 3
Dependent Claim
22 words
A process as claimed in claim 1 wherein said thixotropic material is vibrated during said dipping step and during said pressing step.
Claim 4
Dependent Claim
23 words
A process as claimed in claim 1 wherein said thixotropic material is vibrated in a level parallel to the surface of said material.
Claim 5
Dependent Claim
20 words
