Open the CIPO recordAbstract From the Canadian patent
An electronic device (10) is made by a method of connecting a circuit member (18) to a substrate (12). The circuit member has a discontinuous passivating layer (20) with recesses therein establishing electrical contacts. The member is connected to a mounting surface (14) of a substrate having conductive paths (16). An adhesive (26) including a resin with spaced conductive metal particles suspended therein is applied over the conductive paths. The distance between electrical contacts (22) and the conductive paths is decreased to provide electrical conduction through the adhesive while maintaining the adhesive between conductive paths non-conductive. The conductive paths may have established …

Why it's free to use
- Filed November 20, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 20, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 20, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
