Devices may be soldered directly into a circuit with a soldering iron at amaximum iron temperature of 245C for a time of up to 10 seconds at least 1.5mm from the seal. At aniron temperature of 245C to 400C the maximum soldering time is 5 seconds at least 5mm from the seal. . These devices may be dip-soldered at asolder temperature of 245C for a maximum soldering time of 5 seconds. The case temperature during dip-soldering must not at any time exceed the maximum storage tem- perature. These recommendations apply to a device mounted flush on a board having punched-through holes, or spaced at least 1.5mm above a board having plated-through holes. . Care should be taken not to bend the leads nearer than 1.5mm from the seal. . If devices are stored at temperatures above 100C before incorporation into equipment, some deterioration of the external surface is likely to occur which may make soldering into the circuit difficult. Under these circumstances the leads should be retinned using a suitable activated flux.
