(a) solder within the temperature and time combinations indicated by the slanted lines in the following graphs. (b) excessive soldering conditions may cause dissolution of metallization or deterioration of solder-wetting on the external electrode. (c) in case of repeated soldering, the accumulated soldering time should be within the range shown in the figure below.
