ABSTRACT:
Proposed is an improved heat-sealable connector having aligned lines of an electroconductive paste formed by screen printing on the surface of a flexible substrate. Different from conventional heat-sealable connectors, the electroconductive lines are not formed directly on the surface of the substrate but the substrate surface is first provided with a layer of a solvent-absorptive material and the electroconductive lines are formed on the solvent absorptive layer by screen printing so that the screen-printed lines of the paste never cause running to broaden the line width by virtue of immediate absorption of the solvent in the paste into the solvent-absorptive layer to contribute not only to the productivity but also to the quality of the product connectors.
