SPECIFICATION FOR APPROVAL
Mounting of the test sample onto the test board shall be either of following methods.
(1) Mounting by solder dipping
Epoxy based glue shall be applied in the middle of two lands of the test board. The
resistor shall be mounted in such a way that the electrodes of resistors will be evenly
placed in the land area and then adhesive resin shall be cured. After applying the Resin
Flux with 25 weight % Methyl Alcohol, the board shall be soldered by dipping into a
molten solder bath with 260 ± 5℃ for 3 to 5 seconds
(2) Mounting by Reflow soldering
Solder paste with approximate 200μm thickness shall be applied to the land of test board.
The resistor shall be mounted in such way that the electrodes of resistors will be evenly
placed in the land area and then shall be soldered under the circumstance that the surface
temperature of the board shall be raised 245 ± 5℃(peak) for 5 to 10 seconds in an
upper-heater oven.
