Abstract
Abstract There is provided a soluble chemical layer affixed to a rigid backing, whereupon an electronic configuration is printed and covered with a lacquer. The pattern and lacquer coating are then separated from the backing by dissolving the soluble chemical. Once free, the pattern is transferred to and fused to the substrate.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
70 words
A method of manufacturing a film-type electronic device comprising: a. attaching a water soluble layer to a rigid reinforcing base, b. applying a pattern of film having electrical properties to said soluble layer, and c. drying said pattern of film while maintaining said soluble layer in attachment with said base; d. applying a water insoluble top layer in adhering overlying relation to said pattern of film to provide support thereto.
Claim 2
Independent Claim
70 words
A method of manufacturing a film-type electronic device comprising: a. attaching a water soluble layer to a rigid reinforcing base, b. applying a pattern of film having electrical properties to said soluble layer, and c. drying said pattern of film while maintaining said soluble layer in attachment with said base; d. applying a water insoluble top layer in adhering overlying relation to said pattern of film to provide support thereto.
Claim 3
Dependent Claim
32 words
The method of claim 1 further comprising: a. dissolving said soluble layer to free said pattern of film and accompanying top layer, and b. applying said pattern of film to a substrate.
Claim 4
Dependent Claim
36 words
The method of claim 2 wherein said pattern of film is applied through silk-screen methods to said soluble layer, and further comprising the step of drying said film pattern prior to application of said top layer.
Claim 5
Dependent Claim
36 words
The method of claim 3 further comprising the step of heating said substrate with the pattern of film applied to a temperature and for a duration sufficient to fuse the pattern of film to said substrate.
Claim 6
Dependent Claim
20 words
The method of claim 3 wherein said soluble layer is comprised of decalcomania paper adhered to said rigid reinforcing base.
Claim 7
Dependent Claim
20 words
The method of claim 5 wherein said reinforcing base is fluid absorbable to enhance the dissolution of said soluble layer.
Claim 8
Dependent Claim
100 words
A film-type electronic device comprising: a. a substrate, and b. a film pattern having electrical properties applied to said substrate by attaching a water soluble layer to a rigid reinforcing base, applying a pattern of film having electrical properties to said soluble layer, drying said pattern of film while maintaining said soluble layer in attachment with said base, applying a water insoluble top layer in adhering overlying relation to said pattern of film to provide support thereto, dissolving said soluble layer to free said pattern of film and accompanying top layer, and applying said pattern of film to said substrate.
Claim 9
Dependent Claim
100 words
A film-type electronic device comprising: a. a substrate, and b. a film pattern having electrical properties applied to said substrate by attaching a water soluble layer to a rigid reinforcing base, applying a pattern of film having electrical properties to said soluble layer, drying said pattern of film while maintaining said soluble layer in attachment with said base, applying a water insoluble top layer in adhering overlying relation to said pattern of film to provide support thereto, dissolving said soluble layer to free said pattern of film and accompanying top layer, and applying said pattern of film to said substrate.
