SnPb solders – Infrared Soldering

NB:

• these proﬁles are given for mid size components.

• continuous lines: typical process (terminal temperature).

• dotted lines: process limits, bottom process limit (terminal temperature),

upper process limit (top surface temperature).

III.2. Moisture Sensitivity Classiﬁcation

Our standard lead-free terminations - S and C types - have been fully tested

and are compliant with the requirements mentioned in speciﬁcation JEDEC STD

020 (level 1: not moisture sensitive).

III.3. Whiskers Classiﬁcation

Our standard lead-free terminations - S and C types - have been fully tested

and are compliant with the requirements mentioned in speciﬁcation JEDEC

STD 201. Our terminations exhibit a matte ﬁnish and receive a special heat

treatment to relieve stress inside the tin.

III.4. Pad Dimensions

The metalized pads on the end user’s substrate must be properly designed.

Improper spacing or dimensioning of the pads may result in poor solder joints

or a tombstone effect. Pad designs are given below for the most common sizes

of multilayer ceramic capacitors for both wave and reﬂow soldering.

NB: these dimensions are suggested for a reﬂow soldering process. If a wave

soldering process is used, the X dimension has to be increased by 0.50mm

(0.40mm for L and A case sizes), thus leading to an increase of 1.00mm to the

L dimension (0.80mm for L and A case sizes).
