Open the CIPO recordAbstract From the Canadian patent
A printed circuit board handle is disclosed for use with a printed circuit board. The printed circuit board handle includes a flange that extends for the length of the handle and is mounted to the printed circuit board. Two ribs protrude from the side of the flange that is adjacent to the printed circuit board and extend for the length of the handle. The ribs contact the printed circuit board in such a manner as to separate the body of the flange from the printed circuit board and thereby prevent the capillary action that causes entrapment of flux between the flange and the printed circuit board during the wave soldering process.

Why it's free to use
- Filed January 3, 1992 and granted November 20, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 3, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 3, 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.
