Abstract
Abstract A pallet for holding a printed circuit board on a conveyor in a solder wave machine which applies molten solder to the underside of the printed circuit board for completing connections, includes a pair of longitudinally extending first and second bars mounted on a frame, the bars including a pair of oppositely disposed longitudinally-extending grooves for receiving the opposite side marginal edges of the printed circuit board. Each one of the grooves is substantially channel-shaped and extends to the rear end portion of the bars so that the printed circuit board may be slipped into the grooves at the rear end portion of the bars to insert the board in position. One of the bars is transversely movable relative to the frame, and the other bar is fixed in position on the frame, the movable bar being fixed releasably to the first bar in an adjusted position to the frame for accommodating various different sizes of boards. A transversely extending third bar mounted on the front portion of the frame includes a lengthwise extending groove for receiving an end marginal edge of the printed circuit board. The lower edge of the transversely disposed bar extends below the underside of the printed circuit board to cut into and spread out the wave of molten solder produced by the solder wave applying machine for distributing it over the underside of the printed circuit board.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
168 words
A pallet for holding printed circuit boards on conveying means in a solder wave machine, said machine flowing molten solder in a wave to solder connections on the underside of the board, said pallet comprising: a frame; a pair of longitudinally-extending first and second bars mounted on said frame; attaching means for mounting said frame to said conveying means; means defining a pair of oppositely disposed longitudinally-extending grooves in said bars for receiving the opposite side marginal edges of printed circuit boards; a transversely disposed plow bar mounted on the front portion of said frame; and means defining a lengthwise extending groove in said transversely disposed plow bar in a common plane with said longitudinally-extending grooves for receiving end marginal edges of printed circuit boards, the lower edge of said plow bar extending below said plane so that the undersides of printed circuit boards cut into and spread out the wave of molten solder for distributing it over the underside of printed circuit boards mounted on said pallet.
Claim 2
Dependent Claim
168 words
A pallet for holding printed circuit boards on conveying means in a solder wave machine, said machine flowing molten solder in a wave to solder connections on the underside of the board, said pallet comprising: a frame; a pair of longitudinally-extending first and second bars mounted on said frame; attaching means for mounting said frame to said conveying means; means defining a pair of oppositely disposed longitudinally-extending grooves in said bars for receiving the opposite side marginal edges of printed circuit boards; a transversely disposed plow bar mounted on the front portion of said frame; and means defining a lengthwise extending groove in said transversely disposed plow bar in a common plane with said longitudinally-extending grooves for receiving end marginal edges of printed circuit boards, the lower edge of said plow bar extending below said plane so that the undersides of printed circuit boards cut into and spread out the wave of molten solder for distributing it over the underside of printed circuit boards mounted on said pallet.
Claim 3
Dependent Claim
52 words
A pallet according to claim 1, wherein an elongated slot is disposed in said plow bar, a fastening member extending through said slot to fix releasably said first longitudinally-extending bar to said plow bar, the rear end portion of said first bar being fixed releasably to the rear portion of said frame.
Claim 4
Dependent Claim
38 words
A pallet according to claim 2, wherein said rear end portion of said frame includes an elongated slot, fastening means extending through the last mentioned slot to fix releasably the rear end portion of said first longitudinally-extending bar.
Claim 5
Dependent Claim
74 words
A pallet according to claim 2, further including an intermediate longitudinally-extending bar mounted on said frame having a pair of longitudinally-extending grooves on opposite sides thereof for receiving side marginal edges of printed circuit boards extending transversely from said opposite sides of said intermediate longitudinally-extending bar between said intermediate transversely extending bar and said first and second longitudinally-extending bars, means for fixing releasably said intermediate bar releasably in an adjusted position to said frame.
Claim 6
Dependent Claim
15 words
A pallet according to claim 4, wherein said attaching means includes a pair of pins.
Claim 7
Dependent Claim
191 words
A pallet for holding printed circuit boards on conveying means in solder applying machines, comprising: a frame; a pair of longitudinally-extending first and second bars mounted on said frame; attaching means for mounting said frame to said conveying means; means defining a pair of oppositely disposed longitudinally-extending grooves in said bars for receiving the opposite side marginal edges of printed circuit boards, each one of said grooves being substantially channel-shaped and extending to the rear end portion of said bars so that printed circuit boards may be slipped into said grooves at the rear end portions of said bars to insert the boards in position; means for mounting transversely movably said first bar on said frame; means for fixing said second bar to said frame; and means for fixing releasably said first bar in an adjusted position to said frame for accommodating various different sizes of printed circuit boards, further including a transversely disposed plow bar mounted on the front portion of said frame, means defining a lengthwise extending groove in said plow bar in a common plane with the longitudinally-extending grooves for receiving end marginal edges of printed circuit boards.
