Integrated Load Compensation Device

View page
US Patent:
50608460, Oct 29, 1991
Filed:
Apr 23, 1990
Appl. No.:
7/512722
Inventors:
Daniel J. Schaeffer - Arlington Heights IL
Raymond M. Fardoux - Wilmette IL
Robert P. Dein - Elmhurst IL
Linda D. Limper - Glenview IL
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
B23K 308
US Classification:
228447
Abstract:
The present invention discloses a device for positioning a multi-planar or multi-leaded surface mount electronic component on a printed circuit board (PCB) during reflow soldering. By design this non-conductive device made of thermoplastic resins comprises a fence, having a cavity, wherein the electronic component is positioned relative to printed circuit board foot print contacts. Attached to the bottom surface of the fence is a pair of collapsible slotted pegs. These pegs extend vertically downward from the fence and are adapted to provide a snap-fit insertion and retention mechanism whereby the fence is held in place by inserting the collapsible pegs into holes in a printed circuit board. Thereafter, a pair of cantilever beams which are attached to the fence sidewalls and extend into the fence cavity, make contact with the electronic component. As the fence is inserted into the printed circuit board, the cantilever beams press and hold the electronic component in place during reflow soldering.

US Patent:
39860493, Oct 12, 1976
Filed:
Jun 30, 1975
Appl. No.:
5/591388
Inventors:
Whitney Robertson Campbell - Elk Grove Village IL
Raymond Maurice Fardoux - Wilmette IL
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H03K 508
H03K 114
US Classification:
307237
Abstract:
An audio compressor amplifier including an operational amplifier with compressor means connected from the output to the input for compressing signals at the output to a predetermined constant level in a predetermined attack time and including a plurality of diodes connected to reduce the series resistance in the compressor means for decreasing the attack time when the output signal exceeds the predetermined constant level by a predetermined amount, and a gain control feedback resistor connected from the output to the input of the operational amplifier and including a second resistor and a plurality of diodes connected in parallel therewith to reduce the gain of the operational amplifier and provide peak limiting action when a signal at the output exceeds a predetermined value in excess of the predetermined constant level.
