Knowles Safety Certified capacitors comply with

international UL and TÜV specifications to offer

designers the option of using a surface mount ceramic

multilayer capacitor to replace leaded film types.

Offering the benefits of simple pick-and-place

assembly, reduced board space required and lower

profile, they are also available in a FlexiCap™ version to

reduce the risk of mechanical cracking.

Knowles high voltage capacitor expertise means the

range offers among the highest range available of

capacitance values in certain case sizes. Applications

include: modems, AC-DC power supplies and where

lightning strike or other voltage transients represent a

threat to electronic equipment.

Soldering Information

Knowles / Syfer MLCCs are compatible with all recognised

soldering/mounting methods for chip capacitors. A detailed

application note is available at

www.knowlescapacitors.com/syfer

Reflow Soldering

Knowles recommend reflow soldering as the preferred method

for mounting MLCCs. Knowles MLCCs can be reflow soldered

using a reflow profile generally defined in IPC/FEDEC J-STD-

020. Sn plated termination chip capacitors are compatible with

both conventional and lead free soldering with peak

temperatures of 260º to 270ºC acceptable.

The heating ramp rate should be such that components see a

temperature rise of 1.5º to 4ºC per second to maintain

temperature uniformity through the MLCC.

The time for which the solder is molten should be maintained

at a minimum, so as to prevent solder leaching. Extended

times above 230ºC can cause problems with oxidation of Sn

plating. Use of an inert atmoshere can help if this problem is

encountered. Palladium/Silver (Pd/Ag) terminations can be

particularly susceptible to leaching with free lead, tin rich

solders and trials are recommended for this combination.

Cooling to ambient temperature should be allowed to occur

naturally, particularly if larger chip sizes are being soldered.

Natural cooling allows a gradual relaxation of thermal

mismatch stresses in the solder joints. Forced cooling should

be avoided as this can induce thermal breakage.

Wave Soldering

Wave soldering is generally acceptable, but the thermal

stresses caused by the wave have been shown to lead to

potential problems with larger or thicker chips. Particular care

should be taken when soldering SM chips larger than size 1210

and with a thickness greater than 1.0mm for this reason.

Maximum permissable wave temperature is 270ºC for SM

chips.

The total immersion time in solder should be kept to a

minimum. It is strongly recommended that Sn/Ni plated

terminations are specified for wave soldering applications.

Solder Leaching

Leaching is the term for the dissolution of silver into the solder

causing a failure of the termination system which causes

increased ESR, tan

and open circuit faults, including

ultimately the possibility of the chip becoming detached.

Leaching occurs more readily with higher temperature solders

and solders with a high tin content. Pb free solders can be very

prone to leaching certain termination systems. To prevent

leaching, exercise care when choosing solder allows and

minimize both maximum temperature and dwell time with the

molten solder.

Plated terminations with nickel or copper anti-leaching barrier

layers are available in a range of top coat finishes to prevent

leaching occurring. These finishes also include Knowles

FlexiCap

for improved stress resistance post soldering.

Multilayer ceramic chip with nickel or copper barrier

terminat

ion

Rework of Chip Capacitors

Knowles recommend hot air/gas as the preferred method of

applying heat for rework. Apply even heat surrounding the

component to minimise internal thermal gradients. Soldering

irons or other techniques that apply direct heat to the chip or

surrounding area, should not be used as these can result in

micro cracks being generated.

Minimise the rework heat duration and allow components to

cool naturally after soldering.

Use of Silver Loaded Epoxy Adhesives

Chip capacitors can be mounted to circuit boards using silver

loaded adhesive provided the termination material of the

capacitor is selected to be compatible with the adhesive. This

is normally PdAg. Standard tin finishes are often not

recommended for use with silver loaded epoxies as there can

be electrical and mechanical issues with the joint integrity due

to material mismatch.

Handling & Storage

Components should never be handled with fingers;

perspiration and skin oils can inhibit solderability and will

aggravate cleaning.

Chip capacitors should never be handled with metallic

instruments. Metal tweezers should never be used as theses

can chip the product and leave abraded metal tracks on the

product surface. Plastice or plastic coated metal types are

readily available and recommended – these should be used

with an absolute minimum of applied pressure.

Incorrect storage can lead to problems for the user. Rapid

tarnishing of the terminations, with an associated degradation

of solderability, will occur if the product comes into contact

with industrial gases such as sulphur dioxide and chlorine.

Storage in free air, particularly moist or polluted air, can result

in termination oxidation.

Packaging should not be opened until the MLCs are required

for use. If opened, the pack should be re-sealed as soon as

practicable. Alternatively, the contents could be kept in a

sealed container with an envirinmental control agent.

Long term storage conditions, ideally, should be temperature

controlled between -5º and +40ºC and humidity controlled

between 40 and 60% R.H.

Taped product should be stored out of direct sunlight, which

might promote deterioration in tape or adhesive performance.

Product, store under the conditions recommended above, in its

“as received” packaging, has a minimum shelf life of 2 years.

SM Pad Design

Knowles conventional 2-terminal chip capacitors can generally

be mounted using pad designs in accordance with IPC-7351,

Generic Requirements for Surface Mount Design and Land

Pattern Standards, but there are some other factors that have

been shown to reduce mechanical stress, such as reducing the

pad width to less than the chip width. In addition, the position

of the chip on the board should also be considered.

3-terminal components are not specifically covered by IPC-

7351, but recommended pad dimensions are included in the

Knowles catalogue/website for these components.
