Abstract
Abstract In a method of providing spacers on an insulating substrate, by which spacers the thickness of a connection between an electrical component and a substrate is adjusted, the spacers are rigidly provided on the substrate as a thick film pattern simultaneously with and with the same material as is used for at least one further thick film coating required for an electrical circuit on the substrate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
81 words
A method of providing spacers on an insulating substrate, said spacers adjusting the thickness of electrical connections between electrical components and said substrate, said method comprising rigidly forming said spacers on said substrate as a thick film pattern by simultaneously providing said spacers on said substrate together with at least one further thick film coating which is required for providing electrical circuits on said substrate, said spacer being of the same material as said at least one further thick film coating.
Claim 2
Independent Claim
81 words
A method of providing spacers on an insulating substrate, said spacers adjusting the thickness of electrical connections between electrical components and said substrate, said method comprising rigidly forming said spacers on said substrate as a thick film pattern by simultaneously providing said spacers on said substrate together with at least one further thick film coating which is required for providing electrical circuits on said substrate, said spacer being of the same material as said at least one further thick film coating.
Claim 3
Dependent Claim
20 words
A method as claimed in claim 1, wherein said spacers are provided on said substrate by a screen printing process.
Claim 4
Dependent Claim
16 words
a substrate having spacers formed thereon by the method as claimed in claims 1 or 2.
Claim 5
Dependent Claim
28 words
A substrate as claimed in claim 3, wherein an electrical component bears on said spacers, and is connected to said substrate by means of solder or conductive adhesives.
Claim 6
Dependent Claim
16 words
A method as claimed in claim 1, wherein said spacers are formed of an insulating material.
Claim 7
Dependent Claim
16 words
A method as claimed in claim 2, wherein said spacers are formed of a conducting material.
Claim 8
Dependent Claim
19 words
A method as claimed in claim 1, wherein said spacers are formed to a thickness of approximately 40 microns.
