Abstract
An apparatus which creates a pre-engineered solvent bond is disclosed which allows the bond characteristics of the resultant solvent bond to be predetermined. These characteristics can thus be chosen by the part designer with confidence that inherent variations in the assembly process will not unduly impact the resultant bond. The design establishes a specific volume through removable shims. Solvent added to this volume acts to dissolve material so that the predetermined bond characteristics are created.
Claims2
A joint for bonding items together by a solvent comprising:
- a. a first surface made of a nonporous material which is soluble in the solvent being used;
- b. a second surface made of a nonporous material which is soluble in the solvent being used wherein said first and second surfaces are to be bonded together;
- c. a means for retaining said surfaces in the desired relation to each other in three-dimensional space, said means having a fixed relationship to each of said surfaces;
- d. a means for creating a reservoir between said surfaces prior to bonding wherein said reservoir is adjacent to both of said surfaces and wherein said reservoir establishes a volume into which said solvent may be introduced and which is appropriate to create a bond having specifically desired bond characteristics and wherein said means for creating a reservoir comprises a spacer having a predetermined thickness positioned between said surfaces and wherein said comprises a removable shim positioned between said surfaces;
- and
- e. a means for distributing said solvent.
