PC board should be designed so that products can prevent damage from
mechanical stress when warping the board.
8-2. Soldering
Mildly activated rosin fluxes are preferred. The terminations are suitable for re-flow soldering systems. If hand soldering
cannot be avoided, the preferred technique is the utilization of hot air soldering tools.
Note.
If wave soldering is used ,there will be some risk.
Re-flow soldering temperatures below 240 degrees, there will be non-wetting risk
8-2.1 Lead Free Solder Re-flow :
Recommended temperature profiles for lead free re-flow soldering in Figure 1. (Refered to J-STD-020C)
8-2.2 Soldering Iron :
Products attachment with a soldering iron is discouraged due to the inherent process control limitations. If a
soldering iron must be employed the following precautions are recommended. for Iron Soldering in Figure 2.
Note :
d) 1.0mm tip diameter (max)
a) Preheat circuit and products to 150° C.
e) Use a 20 watt soldering iron with tip diameter of 1.0mm
f) Limit soldering time to 4-5 secs.
b) 350° C tip temperature for Ferrite chip bead (max)
c) Never contact the ceramic with the iron tip
