Hand Soldering Gradual Cooling Soldering Preheating 230 150 280 Gradual Cooling Natural cooling Over 2mins. PG. 5 31.07.2008 wave and re-flow soldering systems. If hand soldering cannot be avoided, the preferred technique is the utilization of hot by the difference in coefficients of expansion between solder, chip and substrate. Our terminations are suitable for all Mildly activated rosin fluxes are preferred. The minimum amount of solder can lead to damage from the stresses caused products, wave soldering of large size products is discouraged. Recommended temperature profile for wave soldering seen by the circuit when immersed in the molten solder wave, typical at 240°C. Due to the risk of thermal damage to Wave soldering is perhaps the most rigorous of surface mount soldering processes due to the steep rise in temperature Products attachment with soldering iron is discouraged due to the inherent process control limitations. In the event that is shown in Figure 2. Soldering a soldering iron must be employed the following precautions are recommended. 7-2.3 Soldering Iron (Figure 2) : Note : 230 150 Preheating c) Never contact the ceramic with the iron tip e) Use a 20 watt soldering iron with tip diameter of 1.0mm cooling Natural f) Limit soldering time to 3 secs. d) 1.0mm tip diameter (max) 230 250 150 Preheating Soldering b) 280°C tip temperature (max) a) Preheat circuit and products to 150°C. 7-2.2 Solder Wave : Recommended temperature profiles for re-flow soldering in Figure 1. 7-2.1 Solder Re-flow : air soldering tools. 7-2.
