Means for assembling printed circuits with components

Claim 1

IN FLUXING APPARATUS FOR ASSEMBLY LINE OPERATION, A CONVEYOR CARRYING A PLURALITY OF PRINTED CIRCUIT BOARD ASSEMBLIES IN HORIZONTAL POSITION WHICH BOARDS HAVE APPLIED CONDUCTIVE CIRCUIT CONFIGURATION TO ONE SURFACE WHICH IT IS DESIRED TO COAT WITH FLUX FOR SOLDERING PURPOSES, A DRUM ROTATABLY MOUNTED WITH ITS AXIS AT RIGHT ANGLES TO THAT OF THE CONVEYOR, SAID DRUM HAVING OPENING IN ITS SURFACE OF THE SAME CONFIGURATION AS THAT OF THE SURFACE OF THE CONDUCTIVE CIRCUIT PORTION OF THE PRINTED CIRCUIT BOARDS WHICH IT IS DESIRED TO FLUX, SCREEN CLOSURE MEMBERS MOUNTED IN EACH OPENING, A FLUX BATH SUPPORTED BELOW THE DRUM INTO WHICH THE LOWER EDGE SUBMERGES AS THE DRUM ROTATES TO FILL THE SCREEN CLOSURE MEMBERS WITH THE FLUX, A SOURCE OF AIR UNDER PRESSURE, AND AIR NOZZLE MEANS CONNECTED TO SAID SOURCE OF AIR PRESSURE AND MOUNTED WITHIN THE DRUM TO BLOW THE FLUX OUT OF THE SCREEN CLOSURE MESH AND ON TO THE LOWER SURFACE OF EACH BOARD AS THE SCREEN MEMBER REACHES THE TOP POSITION IN PROXIMITY TO THE LOWER SURFACE OF THE PASSING PRINTED CIRCUIT BOARD.
