... Philips Semiconductors Dual retriggerable monostable multivibrator with reset SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities ...

... Philips Semiconductors Dual retriggerable monostable multivibrator with reset R EPAIRING SOLDERED JOINTS Fix the component by first soldering two diagonally- opposite end leads. Use only a low voltage soldering iron (less than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds 300 C. When using a dedicated tool, all other leads can be soldered in one operation within seconds between 270 and 320 C ...
