Multilayer varistors (MLVs) Standard series Soldering directions 1 Terminations 1.1 Nickel barrier termination The nickel barrier layer of the silver/nickel/tin termination prevents leaching of the silver base metallization layer. This allows great flexibility in the selection of soldering parameters. The tin prevents the nickel layer from oxidizing and thus ensures better wetting by the solder. The nickel barrier termination is suitable for all commonly-used soldering methods.
Multilayer varistors (MLVs) Standard series 1.3 Silver-platinum termination Silver-platinum terminations are mainly used for the large case sizes 1812 and 2220. The silverplatinum 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.

Multilayer varistors (MLVs) Standard series 3.5 Tinned copper alloy All EPCOS CU types with tinned termination are approved for lead-free and SnPb soldering. 3.6 Tinned iron wire All EPCOS SHCV types with tinned termination are approved for lead-free and SnPb soldering. 4 Solder joint profiles / solder quantity 4.1 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.
Multilayer varistors (MLVs) Standard series Good and poor solder joints caused by amount of solder in reflow soldering. 5 Conductive adhesion Attaching surface-mounted devices (SMDs) with electrically conductive adhesives is a commercially attractive method of component connection to supplement or even replace conventional soldering methods.
Multilayer varistors (MLVs) Standard series A further advantage of adhesion is that the components are subjected to virtually no temperature shock at all. The curing temperatures of the adhesives are between 120 °C and 180 °C, typical curing times are between 30 minutes and one hour. The bending strength of glued chips is, in comparison with that of soldered chips, higher by a factor of at least 2, as is to be expected due to the elasticity of the glued joints.
Multilayer varistors (MLVs) Standard series Note: Leaching of the termination Effective area at the termination might be lost if the soldering temperature and/or immersion time are not kept within the recommended conditions. Leaching of the outer electrode should not exceed 25% of the chip end area (full length of the edge A-B-C-D) and 25% of the length A-B, shown below as mounted on substrate. As a single chip 7 As mounted on substrate Notes for proper soldering 7.
Multilayer varistors (MLVs) Standard series 7.5 Adhesive application Thin or insufficient adhesive causes chips to loosen or become disconnected during curing. Low viscosity of the adhesive causes chips to slip after mounting. It is advised to consult the manufacturer of the adhesive on proper usage and amounts of adhesive to use. 7.6 Selection of flux Used flux should have less than or equal to 0.

Multilayer varistors (MLVs) Standard series 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 filters, SMD disk varistors (CU types), leaded transient voltage/ RFI suppressors (SHCV types)) for certain areas of application, including recommendations about incorporation/design-in of these products into customer applications.
Multilayer varistors (MLVs) Standard series 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 before storage.
Multilayer varistors (MLVs) Standard series Conductive adhesive gluing Only multilayer varistors (MLVs) with an AgPd termination are approved for conductive adhesive gluing. 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.
Important notes 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 requirements that are often placed on our products in the areas of application concerned.
