3. Standard Soldering Conditions
(1) Soldering Methods
Use flow and reflow soldering methods only.
Use standard soldering conditions when soldering chip
ferrite beads.
In cases where several different parts are soldered, each
having different soldering conditions, use those
conditions requiring the least heat and minimum time.
Solder: Use Sn-3.0Ag-0.5Cu solder. Use of Sn-Zn based
solder will deteriorate performance of products.
If using BLA series with Sn-Zn based solder,
please contact Murata in advance.
Flux:
o Use Rosin-based flux.
In case of using RA type solder, products should be
cleaned completely with no residual flux.
o Do not use strong acidic flux (with chlorine content
exceeding 0.20wt%)
o Do not use water-soluble flux.
For additional mounting methods, please contact Murata.
