Soldering directions

1 Terminations and soldering methods

1.1 Nickel barrier termination

The nickel barrier layer of the silver/nickel/tin termination prevents leaching of the silver base met-

allization layer. This allows great flexibility in the selection of soldering parameters. The tin pre-

vents the nickel layer from oxidizing and thus ensures better wetting by the solder. The nickel bar-

rier termination is suitable for lead-free soldering, as well as for other commonly-used soldering

methods.

Multilayer CTVS: Structure of nickel barrier termination

1.2 Silver-platinum termination

Silver-platinum terminations are mainly used for the large EIA case sizes 1812 and 2220. The sil-

ver-platinum termination is approved for reflow soldering, SnPb soldering and lead-free soldering

with a silver containing solder paste. In case of SnPb soldering, a solder paste Sn62Pb36Ag2 is

recommended. For lead-free reflow soldering, a solder paste SAC, e.g. Sn95.5Ag3.8Cu0.7, is

recommended.

1.3 Silver-palladium termination

Silver-palladium terminations are designed for the use of conductive adhesivs. Lead-free reflow

soldering does not form a proper solder joint. In general reflow or wave soldering is not recom-

mended.

1.4 Tinned iron wire

All SHCV types with tinned terminations are suitable for lead-free and SnPb soldering.

2.2 Wave soldering temperature profile

Temperature characteristics at component terminal with dual-wave soldering

3 Solder joint profiles / solder quantity

3.1 Nickel barrier termination

If the meniscus height is too low, that means the solder quantity is too low, the solder joint may

break, i.e. the component becomes detached from the joint. This problem is sometimes interpret-

ed as leaching of the external terminations.

If the solder meniscus is too high, i.e. the solder quantity is too large, the vise effect may occur.

As the solder cools down, the solder contracts in the direction of the component. If there is too

much solder on the component, it has no leeway to evade the stress and may break, as in a vise.

The figures below show good and poor solder joints for dual-wave and infrared soldering.

5 Notes for proper soldering

5.1 Preheating and cooling

According to IEC 60068-2-58. Please refer to section 2 of this chapter.

5.2 Repair/ rework

Manual soldering with a soldering iron must be avoided, hot-air methods are recommended for

rework purposes.

5.3 Cleaning

All environmentally compatible agents are suitable for cleaning. Select the appropriate cleaning

solution according to the type of flux used. The temperature difference between the components

and cleaning liquid must not be greater than 100 °C. Ultrasonic cleaning should be carried out

with the utmost caution. Too high ultrasonic power can impair the adhesive strength of the metal-

lized surfaces.

5.4 Solder paste printing (reflow soldering)

An excessive application of solder paste results in too high a solder fillet, thus making the chip

more susceptible to mechanical and thermal stress. Too little solder paste reduces the adhesive

strength on the outer electrodes and thus weakens the bonding to the PCB. The solder should be

applied smoothly to the end surface.

Multilayer varistors (MLVs)

Automotive E series

Page 77 of 86Please read Cautions and warnings and

Important notes at the end of this document.

5.5 Selection of flux

Used flux should have less than or equal to 0.1 wt % of halogenated content, since flux residue

after soldering could lead to corrosion of the termination and/or increased leakage current on the

surface of the component. Strong acidic flux must not be used. The amount of flux applied should

be carefully controlled, since an excess may generate flux gas, which in turn is detrimental to sol-

derability.

5.6 Storage of CTVSs

Solderability is guaranteed for one year from date of delivery for multilayer varistors, CeraDiodes

and ESD/EMI filters (half a year for chips with AgPt terminations) and two years for SHCV compo-

nents, provided that components are stored in their original packages.

Storage temperature: 25 °C to +45 °C

Relative humidity: ≤75% annual average, ≤95% on 30 days a year

The solderability of the external electrodes may deteriorate if SMDs and leaded components are

stored where they are exposed to high humidity, dust or harmful gas (hydrogen chloride, sulfurous

acid gas or hydrogen sulfide).

Do not store SMDs and leaded components where they are exposed to heat or direct sunlight.

Otherwise the packing material may be deformed or SMDs/ leaded components may stick togeth-

er, causing problems during mounting.

After opening the factory seals, such as polyvinyl-sealed packages, it is recommended to use the

SMDs or leaded components as soon as possible.

Solder CTVS components after shipment from TDK Electronics within the time specified:

CTVS with Ni barrier termination: 12 months

CTVS with AgPt termination: 6 months

SHCV (leaded components): 24 months

5.7 Placement of components on circuit board

Especially in the case of dual-wave soldering, it is of advantage to place the components on the

board before soldering in that way that their two terminals do not enter the solder bath at different

times.

Ideally, both terminals should be wetted simultaneously.

Multilayer varistors (MLVs)

Automotive E series

Page 78 of 86Please read Cautions and warnings and

Important notes at the end of this document.

5.8 Soldering cautions

An excessively long soldering time or high soldering temperature results in leaching of the outer

electrodes, causing poor adhesion and a change of electrical properties of the varistor due to the

loss of contact between electrodes and termination.

Keep the recommended down-cooling rate.

Cautions and warnings

General

Some parts of this publication contain statements about the suitability of our ceramic transient

voltage suppressor (CTVS) components (multilayer varistors (MLVs)), CeraDiodes, ESD/EMI fil-

ters, leaded transient voltage/ RFI suppressors (SHCV types)) for certain areas of application, in-

cluding recommendations about incorporation/design-in of these products into customer applica-

tions. The statements are based on our knowledge of typical requirements often made of our

CTVS devices in the particular areas. We nevertheless expressly point out that such statements

cannot be regarded as binding statements about the suitability of our CTVS components for a

particular customer application. As a rule, EPCOS is either unfamiliar with individual customer ap-

plications or less familiar with them than the customers themselves. For these reasons, it is al-

ways incumbent on the customer to check and decide whether the CTVS devices with the proper-

ties described in the product specification are suitable for use in a particular customer applica-

tion.

Do not use EPCOS CTVS components for purposes not identified in our specifications,

application notes and data books.

Ensure the suitability of a CTVS in particular by testing it for reliability during design-in. Always

evaluate a CTVS component under worst-case conditions.

Pay special attention to the reliability of CTVS devices intended for use in safety-critical

applications (e.g. medical equipment, automotive, spacecraft, nuclear power plant).

Design notes

Always connect a CTVS in parallel with the electronic circuit to be protected.

Consider maximum rated power dissipation if a CTVS has insufficient time to cool down

between a number of pulses occurring within a specified isolated time period. Ensure that

electrical characteristics do not degrade.

Consider derating at higher operating temperatures. Choose the highest voltage class

compatible with derating at higher temperatures.

Surge currents beyond specified values will puncture a CTVS. In extreme cases a CTVS will

burst.

If steep surge current edges are to be expected, make sure your design is as low-inductance

as possible.

In some cases the malfunctioning of passive electronic components or failure before the end of

their service life cannot be completely ruled out in the current state of the art, even if they are

operated as specified. In applications requiring a very high level of operational safety and

especially when the malfunction or failure of a passive electronic component could endanger

human life or health (e.g. in accident prevention, life-saving systems, or automotive battery line

applications such as clamp 30), ensure by suitable design of the application or other measures

(e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by

third parties in the event of such a malfunction or failure. Only use CTVS components from the

automotive series in safety-relevant applications.

Important notes at the end of this document.

Specified values only apply to CTVS components that have not been subject to prior electrical,

mechanical or thermal damage. The use of CTVS devices in line-to-ground applications is

therefore not advisable, and it is only allowed together with safety countermeasures like

thermal fuses.

Storage

Only store CTVS in their original packaging. Do not open the package prior to processing.

Storage conditions in original packaging: temperature 25 to +45°C, relative humidity ≤75%

annual average, maximum 95%, dew precipitation is inadmissible.

Do not store CTVS devices where they are exposed to heat or direct sunlight. Otherwise the

packaging material may be deformed or CTVS may stick together, causing problems during

mounting.

Avoid contamination of the CTVS surface during storage, handling and processing.

Avoid storing CTVS devices in harmful environments where they are exposed to corrosive

gases for example (SOx, Cl).

Use CTVS as soon as possible after opening factory seals such as polyvinyl-sealed packages.

Solder CTVS components after shipment from EPCOS within the time specified:

CTVS with Ni barrier termination, 12 months

CTVS with AgPt termination, 6 months

SHCV, 24 months

Handling

Do not drop CTVS components and allow them to be chipped.

Do not touch CTVS with your bare hands - gloves are recommended.

Avoid contamination of the CTVS surface during handling.

Washing processes may damage the product due to the possible static or cyclic mechanical

loads (e.g. ultrasonic cleaning). They may cause cracks to develop on the product and its parts,

which might lead to reduced reliability or lifetime.

Mounting

When CTVS devices are encapsulated with sealing material or overmolded with plastic

material, electrical characteristics might be degraded and the life time reduced.

Make sure an electrode is not scratched before, during or after the mounting process.

Make sure contacts and housings used for assembly with CTVS components are clean before

mounting.

The surface temperature of an operating CTVS can be higher. Ensure that adjacent

components are placed at a sufficient distance from a CTVS to allow proper cooling.

Avoid contamination of the CTVS surface during processing.

Soldering

Complete removal of flux is recommended to avoid surface contamination that can result in an

instable and/or high leakage current.

Use resin-type or non-activated flux.

Bear in mind that insufficient preheating may cause ceramic cracks.

Rapid cooling by dipping in solvent is not recommended, otherwise a component may crack.

Operation

Use CTVS only within the specified operating temperature range.

Use CTVS only within specified voltage and current ranges.

Environmental conditions must not harm a CTVS. Only use them in normal atmospheric

conditions. Reducing the atmosphere (e.g. hydrogen or nitrogen atmosphere) is prohibited.

Prevent a CTVS from contacting liquids and solvents. Make sure that no water enters a CTVS

(e.g. through plug terminals).

Avoid dewing and condensation.

EPCOS CTVS components are mainly designed for encased applications. Under all

circumstances avoid exposure to:

direct sunlight

rain or condensation

steam, saline spray

corrosive gases

atmosphere with reduced oxygen content

EPCOS CTVS devices are not suitable for switching applications or voltage stabilization where

static power dissipation is required.

This listing does not claim to be complete, but merely reflects the experience of EPCOS AG.

Display of ordering codes for EPCOS products

The ordering code for one and the same EPCOS product can be represented differently in data

sheets, data books, other publications, on the EPCOS website, or in order-related documents

such as shipping notes, order confirmations and product labels. The varying representations of

the ordering codes are due to different processes employed and do not affect the

specifications of the respective products. Detailed information can be found on the Internet

Important notes at the end of this document.

The following applies to all products named in this publication:

1. Some parts of this publication contain statements about the suitability of our products for

certain areas of application. These statements are based on our knowledge of typical re-

quirements that are often placed on our products in the areas of application concerned. We

nevertheless expressly point out that such statements cannot be regarded as binding

statements about the suitability of our products for a particular customer application.

As a rule, we are either unfamiliar with individual customer applications or less familiar with

them than the customers themselves. For these reasons, it is always ultimately incumbent on

the customer to check and decide whether a product with the properties described in the

product specification is suitable for use in a particular customer application.

2. We also point out that in individual cases, a malfunction of electronic components or

failure before the end of their usual service life cannot be completely ruled out in the

current state of the art, even if they are operated as specified. In customer applications

requiring a very high level of operational safety and especially in customer applications in

which the malfunction or failure of an electronic component could endanger human life or

health (e.g. in accident prevention or lifesaving systems), it must therefore be ensured by

means of suitable design of the customer application or other action taken by the customer

(e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by

third parties in the event of malfunction or failure of an electronic component.

3. The warnings, cautions and product-specific notes must be observed.

4. In order to satisfy certain technical requirements, some of the products described in this

publication may contain substances subject to restrictions in certain jurisdictions (e.g.

because they are classed as hazardous). Useful information on this will be found in our Ma-

terial Data Sheets on the Internet (www.tdk-electronics.tdk.com/material). Should you have

any more detailed questions, please contact our sales offices.

5. We constantly strive to improve our products. Consequently, the products described in this

publication may change from time to time. The same is true of the corresponding product

specifications. Please check therefore to what extent product descriptions and specifications

contained in this publication are still applicable before or when you place an order. We also

reserve the right to discontinue production and delivery of products. Consequently, we

cannot guarantee that all products named in this publication will always be available. The

aforementioned does not apply in the case of individual agreements deviating from the fore-

going for customer-specific products.

6. Unless otherwise agreed in individual contracts, all orders are subject to our General

Terms and Conditions of Supply.

quality management system in the automotive industry. Referring to customer requirements

and customer specific requirements (“CSR”) TDK always has and will continue to have the

policy of respecting individual agreements. Even if IATF 16949 may appear to support the

acceptance of unilateral requirements, we hereby like to emphasize that only requirements

mutually agreed upon can and will be implemented in our Quality Management System.

For clarification purposes we like to point out that obligations from IATF 16949 shall only

become legally binding if individually agreed upon.
