METHOD AND APPARATUS FOR DESIGNING PRINTED-CIRCUIT BOARD
A thermal analysis in heating a print-circuit board in a reflowing furnace is simulated by a processor using data required for the design and thermal analysis of the printed-circuit board that carries solder-bonded components. The result of simulation indicates the possibility of existence of unmelt...

| description | A thermal analysis in heating a print-circuit board in a reflowing furnace is simulated by a processor using data required for the design and thermal analysis of the printed-circuit board that carries solder-bonded components. The result of simulation indicates the possibility of existence of unmelted solder bonds heated at peak temperature below a predetermined lower limit and solder bonds heated at temperature above a predetermined upper limit. On the basis of the result, the components that are likely to be heated at inapplicable temperature are redesigned so that they can actually be heated at temperature in the predetermined range. The modification of design is displayed. |
