Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
175 words
THE METHOD OF ESTABLISHING A CONNECTION TO A PRINTED CIRCUIT BOARD WHICH COMPRISES THE STEPS OF: FORMING A WELDABLE TAB-CARRIER AS A BODY WITH TWO OUTSTANDING TABS, BENDING SAID TABS OUT OF THE PLANE OF THE BODY, FORMING APERTURES IN A FIRST LAYER OF EPOXY MATERIAL IN POSITIONS TO RECEIVE SAID TABS, MECHANICALLY PROJECTING SAID TABS THROUGH SAID APERTURES SO THAT SAID TAB CARRIER ABUTS SAID FIRST LAYER OF MATERIAL, SUPERIMPOSING A SECOND LAYER OF IMPERFORATE EPOXY MATERIAL OVER SAID FIRST LAYER OF MATERIAL THEREBY SANDWICHING SAID TAB CARRIER BETWEEN SAID LAYERS, SUPERIMPOSING ON SAID SANDWICHED EPOXY MATERIAL A PLURALITY OF PRINTED CIRCUIT BOARDS EACH COMPRISING A METALLIC CIRCUIT PATTERN AND A B-STAGE EPOXY BASE, PRESSING SAID LAYERS OF MATERIAL TOGETHER AND APPLYING HEAT FOR ANCHORING SAID TAB CARRIER BETWEEN THE LAYERS OF SAID EPOXY MATERIAL FOR FORMING SAID EPOXY MATERIAL AND TAB CARRIER AND CIRCUIT BOARD INTO AN INTEGRAL PACKAGE, DRILLING A HOLE THROUGH SAID PACKAGE TO PROVIDE A PASSAGE IN EDGE-CONTACT WITH SAID BODY AND THE CIRCUIT PATTERNS, AND FINALLY COPPER-PLATING SAID PASSAGE.
