Abstract:
A method of producing a printed board assembly with a given circuitry that includes circuits, components and a customised integrated circuit to which input signals are delivered and which is controlled by software, the circuits, components, and customized integrated circuit are mounted on a primary side of the board, the board having a secondary side opposite the primary side the method comprises the steps of:(i) mounting at least one first programmable logic circuit on the secondary side of the board;(ii) ascertaining whether or not the function of the first programmable logic circuit is satisfactory in relation to said circuits and said components mounted on the printed board assembly when input signals are applied to said logic circuit and when said software is executed in said circuit; and(iii) removing and replacing the first programmable logic circuit by mounting a customised integrated circuit having the same functions and connections as those of the first programmable logic circuit on said primary side of the board.
