SDI453226 SERIES
7-2. Soldering
Mildly activated rosin fluxes are preferred. The minimum amount of solder can lead to damage from the stresses caused
by the difference in coefficients of expansion between solder, chip and substrate. Our terminations are suitable for all
wave and re-flow soldering systems. If hand soldering cannot be avoided, the preferred technique is the utilization of hot
air soldering tools.
7-2.1 Solder Re-flow :
Recommended temperature profiles for re-flow soldering in Figure 1.
7-2.2 Solder Wave :
Wave soldering is perhaps the most rigorous of surface mount soldering processes due to the steep rise in temperature
seen by the circuit when immersed in the molten solder wave, typical at 240°C. Due to the risk of thermal damage to
products, wave soldering of large size products is discouraged. Recommended temperature profile for wave soldering
is shown in Figure 2.
7-2.3 Soldering Iron (Figure 2) :
Products attachment with soldering iron is discouraged due to the inherent process control limitations. In the event that
a soldering iron must be employed the following precautions are recommended.
Note :
a) Preheat circuit and products to 150°C.
b) 280°C tip temperature (max)
c) Never contact the ceramic with the iron tip
d) 1.0mm tip diameter (max)
e) Use a 20 watt soldering iron with tip diameter of 1.0mm
f) Limit soldering time to 3 secs.
