Abstract
Abstract A method of forming a terminal board assembly which comprises the steps of inserting the anchoring parts or pins of electrical accessories or components into holes opening out on one side of an apertured board composed of electrical insulating material and so dimensioned that the inserted ends of the pins are projected beyond the opposite side of the board. Placing a thin imperforate sheet of thermosetting plastic material in juxtaposition to the side of the apertured board from which the pins project. Then applying pressure compressing the plastic sheet against the adjacent side of the board thereby causing the projecting ends of the pins to punch out apertures in the plastic sheet corresponding in size and in registration with the apparatus of the board. Thereafter, subjecting the assembly to a hightemperature environment which first causes the plastic material of the sheet to liquify and flow into the annular spaces between the component pins and the walls of the holes into which they are inserted and then later causes this plastic material to polymerize or harden therein, thereby firmly securing the pins and their associated components to the insulating board.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
301 words
The method of making an electrical board assembly comprising the steps of: providing an apertured mounting board formed at least in part of thermosetting material and having the holes thereof opening out through the opposite sides of the board, inserting component elements into the holes of the board from one side thereof which are so dimensioned with respect to the holes into which they are inserted as to provide a slight annular clearance therearound when centered in the holes and further so that the entering ends of the elements project from the opposite side of the board, bringing a thin imperforate dry sheet formed at least in part of thermosetting material into juxtaposition to the side of the board from which the inserted ends of the component elementS project, the thermosetting material of the sheet having a setting temperature below that of the thermosetting material of the board, compressing the board and sheet together to cause the projecting ends of the component elements to pierce the sheet and punch out holes therein registering with the holes in the board, subjecting the assembly of the punched out sheet and the board with the component elements mounted therein to a heat environment which is above the thermosetting temperature of the sheet but below that of the thermosetting material of the board for a period of time sufficient to cause the thermosetting material of the sheet to liquify and flow into the holes and between the walls thereof and the inserted portions of the component elements, and continuing the subjection of the assembly to said heat environment for a period of time sufficient to cause the thermosetting material of the sheet which has flowed into the holes of the board to take a permanent set and thereby bond the component elements to the board.
Claim 2
Independent Claim
301 words
The method of making an electrical board assembly comprising the steps of: providing an apertured mounting board formed at least in part of thermosetting material and having the holes thereof opening out through the opposite sides of the board, inserting component elements into the holes of the board from one side thereof which are so dimensioned with respect to the holes into which they are inserted as to provide a slight annular clearance therearound when centered in the holes and further so that the entering ends of the elements project from the opposite side of the board, bringing a thin imperforate dry sheet formed at least in part of thermosetting material into juxtaposition to the side of the board from which the inserted ends of the component elementS project, the thermosetting material of the sheet having a setting temperature below that of the thermosetting material of the board, compressing the board and sheet together to cause the projecting ends of the component elements to pierce the sheet and punch out holes therein registering with the holes in the board, subjecting the assembly of the punched out sheet and the board with the component elements mounted therein to a heat environment which is above the thermosetting temperature of the sheet but below that of the thermosetting material of the board for a period of time sufficient to cause the thermosetting material of the sheet to liquify and flow into the holes and between the walls thereof and the inserted portions of the component elements, and continuing the subjection of the assembly to said heat environment for a period of time sufficient to cause the thermosetting material of the sheet which has flowed into the holes of the board to take a permanent set and thereby bond the component elements to the board.
Claim 3
Independent Claim
193 words
The method of bonding component elements to a board comprising the steps of: inserting a component element in each hole of a mounting board so that ends of the elements project from one side of the board, bringing a thin imperforate sheet containing thermosetting material into juxtaposition to the side of the board from which the ends of the component elements project, compressing the board and sheet together to cause the projecting ends of the component elements to pierce the sheet and bring the sheet into surface contact with the adjacent side of the board, subjecting the assembly of the pierced sheet and the board with the component elements inserted therein to a heat environment which is above the thermosetting temperature of the sheet to cause the thermosetting material of the sheet to liquify and flow into the holes of the board and around the inserted portions of the component elements, and continuing the heat environment for a further period of time sufficient to cause the thermosetting material of the sheet which has flowed into the holes of the board to take a permanent set and bond the component elements to the board.
Claim 4
Independent Claim
193 words
The method of bonding component elements to a board comprising the steps of: inserting a component element in each hole of a mounting board so that ends of the elements project from one side of the board, bringing a thin imperforate sheet containing thermosetting material into juxtaposition to the side of the board from which the ends of the component elements project, compressing the board and sheet together to cause the projecting ends of the component elements to pierce the sheet and bring the sheet into surface contact with the adjacent side of the board, subjecting the assembly of the pierced sheet and the board with the component elements inserted therein to a heat environment which is above the thermosetting temperature of the sheet to cause the thermosetting material of the sheet to liquify and flow into the holes of the board and around the inserted portions of the component elements, and continuing the heat environment for a further period of time sufficient to cause the thermosetting material of the sheet which has flowed into the holes of the board to take a permanent set and bond the component elements to the board.
