Claim 1
Independent Claim
240 words
A support tray for printed circuit boards adapted for removable insertion in horizontal position in test ovens and the like, having horizontally positioned tray support brackets therein, comprising in combination: A. a rigid rectangular frame having: i. at least one open end; ii. an end handle secured across said open end; B. a rectangular-shaped printed circuit board of greater width than said frame, superposed on said frame with both side edges of said board extending over and projecting beyond the side edges of said frame, said circuit board being shorter than said frame, such that the closed end of said frame is offset with respect to the end of said circuit board, so as to define a finger hold; C. longitudinally extending insulated runners attached to the bottom side edges of said board, and i. said runners extending over and projecting beyond said side edges of said frame, with said runners resting on said frame and adapted for horizontal tray-insulating support on the support brackets in an oven; D. said end handle further including a seat for an electrical connection and an electrical socket, positioned within said seat and wired to said circuit board; and E. said frame being bent into U-shape and said handle extending vertically above and below the open end of said frame, so as to define a hand clasp, and being bent over at top and bottom as a guard for the electrical connection positioned therein.
