SOLDERING

The indicated temperatures are those at the solder interfaces. MLB740300 handbook, halfpage Advised solder types are types with a liquidus less than or

T

equal to 210 °C. mb ( o C) Solder dots or solder prints must be large enough to wet the contact areas. 200 Footprints for soldering should cover the module contact area +0.1 mm on all sides. Soldering can be carried out using a conveyor oven, a hot 100 air oven, an infrared oven or a combination of these ovens. Hand soldering must be avoided because the soldering iron tip can exceed the maximum permitted temperature of 250 °C and damage the module. 0 0 100 200 300 t (s) 400 The maximum temperature profile and soldering time is indicated as follows (see Fig.25): t = 350 s at 100 °C Fig.25 Maximum allowable temperature profile. t = 300 s at 125 °C t = 200 s at 150 °C t = 100 s at 175 °C t = 50 s at 200 °C t = 5 s at 250 °C (maximum temperature). Cleaning The following fluids may be used for cleaning: • Alcohol • Bio-Act (Terpene Hydrocarbon) • Triclean B/S • Acetone. Ultrasonic cleaning should not be used since this can cause serious damage to the product. 1996 May 21 12, PACKAGE OUTLINE handbook, full pagewidth 25.0 24.6 1.65 22.1 1.25 21.7 4.0 3.6 4.3 3.9 3.1 (4×) 2.9 5.1 13.4 4.9 13.0 2.4 1.2 MSA3522.21234min 0.55 (4×) 0.45 0.25 0.30 M 0.1 3.7 0.20 3.3 5.08 7.62 5.08 (4×) Dimensions in mm.
