2. Solder Paste Printing and Adhesive Application
NFM
NFR
NFL
When reflow soldering the chip EMI suppression filter, the
printing must be conducted in accordance with the
following cream solder printing conditions.
If too much solder is applied, the chip will be prone to
damage by mechanical and thermal stress from the PCB
and may crack.
Standard land dimensions should be used for resist and
copper foil patterns.
• Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc.
• This catalog has only typical specifications because there is no space for detailed specifications. Therefore, please review our product specifications or consult the approval sheet for product specifications before ordering.

When flow soldering the EMI suppression filter, apply the
adhesive in accordance with the following conditions.
If too much adhesive is applied, then it may overflow into
the land or termination areas and yield poor solderability.
In contrast, if insufficient adhesive is applied, or if the
adhesive is not sufficiently hardened, then the chip may
become detached during flow soldering process.
