An electronic device (100) comprises a first substrate (102) having a first circuit pattern disposed thereon which is selectively processed to provide pretinned connection pads (108, 116, 124, 132, 140) for connection to at least one electronic component (142) and a second circuit pattern disposed on a second substrate (104). The second circuit pattern disposed on the second substrate (104) is selectively processed to further provide pretinned connection pads (110, 118, 126) for connection to the first circuit pattern, and the second substrate (104) further has relief provided within a portion thereof to position the at least one electronic component (142) with respect to the pretinned connection pads (108, 116, 124, 132, 140) on the first circuit pattern. The pretinned connection pads (108, 116, 124, 132, 140, 110, 118, 126) are processed using a low residue fluxing agent to enable processing of the first (102) and second (104) substrates and the at least one electronic component (142) in a single operation through an envelope heating device without a requirement for cleaning after reflow.

Cardlike electronic device

A connector (40) for insertion into a portable electronic device (30) provides testing, programming and power thereto. The portable electronic device (30) has a chassis (32) housed therein and further includes a battery cavity (35) with battery contacts (36) therein. The connector (40) has a distal end for contacting the chassis (32) through an access port (34) in the battery cavity (35). A proximal end of the connector (40) is adapted for connection to a cable. The connector (40) has a substrate (50) attached to a printed wire board (41), wherein the printed wire board (41) further comprises a first plurality of conductors (52) thereon for receiving data signals from the cable, and a second plurality of conductors (42) thereon for receiving power signals from the cable. A first plurality of contacts (48) are coupled to the first plurality of conductors (52) at the distal end of the connector (40) for contacting the chassis, and a second plurality of contacts (46) are coupled to the second plurality of conductors (42) at the distal end of the connector (40) for contacting the battery contacts.

Connector for providing programming, testing, and power signals

An improved wood burning stove for providing heated air to a room or similar area includes an enclosed fire chamber, a hearth at the bottom of the fire chamber, draft inlet means at the front of the fire chamber and a flue at the rear of the fire chamber. Within the fire chamber is an enclosed air chamber having lower and upper portions; the lower portion communicates at the bottom of the stove with the ambient air and extends upwardly adjacent the rear wall of the fire chamber to a point below the flue, where it joins with the upper portion. The upper portion of the air chamber extends upwardly toward the front of the fire chamber at an acute angle with the horizontal, preferably between five and twenty-five degrees; at the forward end of the upper portion the air chamber communicates with one or more air pipes which extend to the front of the stove and there open to the ambient air. Ambient air is heated by passing it through the air chamber and air pipes after they have been heated by hot gases rising from a fire burning on the hearth; the hot gases contact the air pipes and the bottom surface of the air chamber's upper portion and, because their normal path of travel to the flue is altered by the positioning of the upper portion of the air chamber, contact the top surface of the air chamber's upper portion as well.

A wood burning stove for providing heated air to a room or similar area includes a fire chamber, a hearth in the forward portion of the fire chamber, draft inlet means at the front of the fire chamber and a flue at the rear of the fire chamber. Between the hearth and the flue is an enclosed air chamber having front and rear walls; the air chamber communicates at its bottom with the ambient air and at its top with one or more air pipes which extend to the front of the stove and there open to the ambient air. A baffle plate is positioned between and spaced from the air chamber and the flue. Ambient air is heated by passing it through the air chamber and air pipes after they have been heated by hot gases rising from a fire burning on the hearth; the hot gases contact the air pipes and the front wall of the air chamber and, because their normal path of travel to the flue is altered by the baffle plate, contact the rear wall of the air chamber as well.
