Therefore, the MLCCs shall be stored in the ambient temperature and the relative humidity of less than 40 and 70%, respectively. Guaranteed storage period is within 6 months from the outgoing date of delivery. Corrosive Gases Since the solderability of the end termination in MLCC was degraded by a chemical atmosphere such as chlorine, acid or sulfide gases, MLCCs must be avoid from these gases. Temperature Fluctuations Since dew condensation may occur by the differences in temperature when the MLCCs are taken DESIGN OF LAND PATTERN When designing printed circuit boards, the shape and size of the lands must allow for the proper amount of solder on the capacitor. The amount of solder at the end terminations has a direct effect on the crack. The crack in MLCC will be easily occurred by the tensile stress which was due to too much amount of solder. In contrast, if too little solder is applied, the termination strength will be insufficiently. Use the following illustrations as guidelines for proper land design. Recommendation of Land Shape and Size.

ADHESIVES When flow soldering the MLCCs, apply the adhesive in accordance with the following conditions. Requirements for Adhesives They must have enough adhesion, so that, the chips will not fall off or move during the handling of the circuit board. They must maintain their adhesive strength when exposed to soldering temperature. They should not spread or run when applied to the circuit board. They should harden quickly. They should not corrode the circuit board or chip material. They should be a good insulator. They should be non-toxic, and not produce harmful gases, nor be harmful when touched. Application Method It is important to use the proper amount of adhesive. Too little and much adhesive will cause poor adhesion and overflow into the land, respectively.

MOUNTING Mounting Head Pressure Excessive pressure will cause crack to MLCCs. The pressure of nozzle will be 300g maximum during mounting. General Capacitors Solder Resist Bending Stress When double-sided circuit boards are used, MLCCs first are mounted and soldered onto one side of the board. When the MLCCs are mounted onto the other side, it is important to support the board as shown in the illustration. If the circuit board is not supported, the crack occur to the ready-installed MLCCs by the bending stress. nozzle force support pin Manual soldering can pose a great risk of creating thermal cracks in chip capacitors. The hot soldering iron tip comes into direct contact with the end terminations, and operator's carelessness may cause the tip of the soldering iron to come into direct contact with the ceramic body of the capacitor. Therefore the soldering iron must be handled carefully, and close attention must be paid to the selection of the soldering iron tip and to temperature control of the tip.

If the chips are dipped into solvent for cleaning, the temperature difference(T) must be less than 100 Cleaning If rosin flux is used, cleaning usually is unnecessary. When strongly activated flux is used, chlorine in the flux may dissolve into some types of cleaning fluids, thereby affecting the chip capacitors. This means that the cleaning fluid must be carefully selected, and should always be new. Notes for Separating Multiple, Shared PC Boards. A multi-PC board is separated into many individual circuit boards after soldering has been completed. If the board is bent or distorted at the time of separation, cracks may occur in the chip capacitors. Carefully choose a separation method that minimizes the bending often circuit board.
