12.1. Land pattern designing
· Standard land dimensions (Flow and Reflow soldering)
The excessive heat by land pads may cause
deterioration at joint of products with substrate.
12.2. Soldering Conditions
Products can be applied to reflow and flow soldering.
(1) Flux,Solder
Flux Use rosin-based flux, but not highly acidic flux (with chlorine content exceeding 0.2(wt)%. )
Do not use water-soluble flux.
Solder Use Sn-3.0Ag-0.5Cu solder
Standard thickness of solder paste : 100 µm to 200 µm
Use of Sn-Zn based solder will deteriorate performance of products.
In case of using Sn-Zn based solder, please contact Murata in advance.
(2) Soldering conditions
· Pre-heating should be in such a way that the temperature difference between solder and ferrite surface is
limited to 150 °C max. Also cooling into solvent after soldering should be in such a way that the temperature
difference is limited to 100 °C max.
Insufficient pre-heating may cause cracks on the ferrite, resulting in the deterioration of product quality.
· Standard soldering profile and the limit soldering profile is as follows.
The excessive limit soldering conditions may cause leaching of the electrode and / or resulting
in the deterioration of product quality.
