A slapper detonator includes an explosive pellet disposed within a detonator housing and a bridge chip disposed within a pocket defined between a pair of printed circuit boards. One of the printed circuit boards is disposed between the bridge chip and the explosive pellet and includes an opening centered over the bridge element to permit a flyer to accelerate before impacting the explosive pellet. The printed circuit board with the opening also establishes a connection between the bridge contact pads and metalized patterns or pads on the other printed ci...
[ What is claimed is:] [11.] A method of manufacturing a slapper detonator comprising the steps ofdefining a pair of metalized pads on one side of a first printed circuit board;defining a pair of metalized pads on each side of a second printed circuit board;connecting each of the metalized pads on the second printed circuit board with a metalized pad on the opposite side of the second board;defining a pocket between the first and second printed circuit boards;placing a bridge chip with contact pads connected by a bridge element in the pocket;positioning ...
