I Cautions and Warnings (2):
The following conditions apply to all goods within the product series of WCAP-CSGP
of Würth Elektronik eiSos GmbH & Co. KG:
2.7 Soldering
•The detailed soldering instructions for reflow and wave soldering are given within Soldering Specification in the datasheet.
•The soldering profile has to be compliant with the technical soldering specification, otherwise this will void the warranty.
•Avoid any other than specified temperature and / or time conditions during soldering.
•Customer needs to ensure that the applied solder paste, the paste thickness and solder conditions are applicable to guarantee a sufficient
solder result according to the relevant criteria of IPC-A-610.
2.8 Cleaning
•Cleaning agents that are used to clean the customer application might damage or change the characteristics of the component, body,
pins or termination.
•Avoid Halogen in the flux or any contaminated flux as well as excessively high ultrasonic cleaning.
•Excessive amount of solder may lead to higher tensile force and chip cracking. Insufficient amount of solder may detach the capacitor due
to defective contacts.
2.9 Coating, molding and potting of the P.C. board
•When coating and molding the P.C. board verify the quality influence on the capacitor.
•Do not use excessive nor insufficient flux.
•Provide enough washing when water-soluble flux is used.
•Verify the curing temperature and assure that there is no harmful decomposing or reaction gas emission during curing.
•Do not exceed the maximal temperature rise of 20°C.
•Consider the preheating conditions as follows to avoid thermal shock:
•If the product is potted in customer applications, the potting material might shrink during and after hardening. The product is exposed to
the pressure of the potting material with the effect that the body and termination is possibly damaged and so the electrical as well as the
mechanical characteristics are endangered to be affected. After the potting material is cured, the body and termination of the product ha-
ve to be checked if any reduced electrical or mechanical functions or destructions have occurred.

2.10 Handling after chip is mounted
•Direct mechanical impact to the product shall be prevented.
•After soldering please pay attention not to bend, twist or distort the P.C. board in handling and storage.
•Avoid excessive pressure during the functional check of the P.C. board.
•Avoid bending stress while breaking the P.C. board.
•It is recommended to use air for natural cooling. When dipping the chips into a solvent for cleaning, the temperature difference (∆T) must
be less than 100°C.
•For reflow soldering two times limitation is recommended.
2.11 Handling of loose chip capacitor
•Wave soldering is recommended only for the following case sizes: 0603 and 0805, thickness< 1mm.
•Once dropped do not use the chip capacitor.
•After mounting avoid piling up P.C. boards to avoid hitting the chip capacitor of another board.
•Please ensure for manual soldering (solder iron) not to exceed the general temperature capabilities as specified above.
•The following conditions are recommended for solder repair by solder iron:
Size
1206 or less 330 ± 20°C >150°C
1210 or more 280°C max >150°C

•Typical time of actual peak temperature: <5 sec (300°C), <3 sec (350°C); as short as possible
•Do not make direct contact with the ceramic dielectric.
