Abstract
Abstract An integrated circuit test system useful for component testing in a temperature chamber or oven under high heat conditions and including a tray having incorporated thereon printed circuit and connectors and two cards, one for mounting devices on sockets for testing and the other having a device load circuitry, each card being connectable with its own printed circuit connector on the tray to permit rapid changes of both test conditions and devices. The cards are easily and rapidly interchangeable for the change of test conditions and devices with the card plug in feature, and levers are provided on the tray for coacting with the printed circuit cards to assist in removal of the cards from the connectors.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
280 words
An integrated circuit test system comprising: A. a tray, including a base and a handle, said handle being in said base and said base constituting a sliding surface for mating engagement with insert guides in a test oven; B. a tray connector mounted on said tray; C. a circuit board connector mounted on said tray, said circuit board connector being elongate and comprising two connector sets mounted back-to-back and having a plurality of female connectors; D. a removable circuit and component board having circuitry thereon and connector at an edge thereof, adapted for operative engagement with said circuit board connector on said tray and said board having a notch therein, said board being elongate and said connector thereon including a plurality of male connectors, said male and female connectors being interengagable to permit assembly and disassembly of a board from said tray, two said circuit boards being mountable on said tray, one said board comprising a load board and the other said board comprising a test device board, said boards including integrated circuits thereon interconnecting load and device components for interconnection with circuitry on said tray through the mating connectors; E. a movable board release lever on said tray, said lever being pivotably mounted and including a board engaging finger and a handle portion, said finger being confinable in said notch with said board in assembled relation on said tray and said finger being engageable with a side of said notch upon rotation of said lever to effect board lateral disengagement from said tray, said lever being engageable with a portion of said board to permit, upon movement, lateral disengagement of said board connections and said board from said tray.
Claim 2
Dependent Claim
280 words
An integrated circuit test system comprising: A. a tray, including a base and a handle, said handle being in said base and said base constituting a sliding surface for mating engagement with insert guides in a test oven; B. a tray connector mounted on said tray; C. a circuit board connector mounted on said tray, said circuit board connector being elongate and comprising two connector sets mounted back-to-back and having a plurality of female connectors; D. a removable circuit and component board having circuitry thereon and connector at an edge thereof, adapted for operative engagement with said circuit board connector on said tray and said board having a notch therein, said board being elongate and said connector thereon including a plurality of male connectors, said male and female connectors being interengagable to permit assembly and disassembly of a board from said tray, two said circuit boards being mountable on said tray, one said board comprising a load board and the other said board comprising a test device board, said boards including integrated circuits thereon interconnecting load and device components for interconnection with circuitry on said tray through the mating connectors; E. a movable board release lever on said tray, said lever being pivotably mounted and including a board engaging finger and a handle portion, said finger being confinable in said notch with said board in assembled relation on said tray and said finger being engageable with a side of said notch upon rotation of said lever to effect board lateral disengagement from said tray, said lever being engageable with a portion of said board to permit, upon movement, lateral disengagement of said board connections and said board from said tray.
Claim 3
Dependent Claim
70 words
A system as claimed in claim 1 wherein one said board accepts devices on sockets and the other said board accepts device load circuitry, said circuit board connector on said tray being connectable with a printed circuit on each said board and each said board being connectable into its own printed circuit connector for permitting rapid changes of both test conditions and devices and facilitating rapid changes of device types.
Claim 4
Dependent Claim
38 words
A system as claimed in claim 1 each said board having a notch therein and two said cam action levers being mounted on said tray for coaction with each said notch for several removement of each said board.
