Storage Store the capacitors where the temperature and relative humidity don’t exceed 40°C and 70%RH. We recommend that the capacitors be used within 6 months from the date of manufacturing. Store the products in the original package and do not open the outer wrapped, polyethylene bag, till just before usage. If it is open, seal it as soon as possible or keep it in a desiccant with a desiccation agent. 2. Construction of Board Pattern Improper circuit layout and pad/land size may cause excessive or not enough solder amount on the PC board. Not enough solder may create weak joint, and excessive solder may increase the potential of mechanical or thermal cracks on the ceramic capacitor. Therefore we recommend the land size to be as shown in the following table: 2.1 Size and recommend land dimensions for reflow soldering .

Mounting 3.1 Sometimes crack is caused by the impact load due to suction nozzle in pick and place operation. In pick and place operation, if the low dead point is too low, excessive stress is applied to component. This may cause cracks in the ceramic capacitor, therefore it is required to move low dead point of a suction nozzle to the higher level to minimize the board warp age and stress on the components. Nozzle pressure is typically adjusted to 1N to 3N (static load) during the pick and place operation.

Soldering 4.1. Wave Soldering Most of components are wave soldered with solder at 230 to 250°C. Adequate care must be taken to prevent the potential of thermal cracks on the ceramic capacitors. Refer to the soldering methods below for optimum soldering benefits.

To optimize the result of soldering, proper preheating is essential: 1) Preheat temperature is too low a. Flux flows to easily b. Possibility of thermal cracks 2) Preheat temperature is too high a. Flux deteriorates even when oxide film is removed b. Causes warping of circuit board c. Loss of reliability in chip and other components Cooling Condition: Natural cooling using air is recommended. If the chips are dipped into a solvent for cleaning, the temperature difference ( T) between the solvent and the chips must be less than 100°C. Δ 4.2 Reflow Soldering Preheat and gradual increase in temperature to the reflow temperature is recommended to decrease the potential of thermal crack on the components. The recommended heating rate depends on the size of component, however it should not exceed 3°C/Sec.

How to Solder Repair by Solder Iron 1) Selection of the soldering iron tip The required temperature of solder iron for any type of repair depends on the type of the tip, the substrate material, and the solder land size. 2) recommended solder iron condition a.) Preheat the substrate to (60°C to 120°C) on a hot plate. Note that due to the heat loss, the actual setting of the hot plate may have to be higher. (For example 100°C to 150°C) b.) Soldering iron power shall not exceed 30 W. c.) Soldering iron tip diameter shall not exceed 3mm. d.) Temperature of iron tip shall not exceed 350°C., and the process should be finished within 5 seconds. ( refer to MIL-STD-202G) f.) Do not touch the ceramic body with the tip of solder iron. Direct contact of the soldering iron tip to ceramic body may cause thermal cracks. g.) After soldering operation, let the products cool down gradually in the room temperature. 5. Handling after chip mounted 5.1 Proper handling is recommended, since excessive bending and twist of the board, depends on the orientation of the chip on the board, may induce mechanical stress and cause internal crack in the capacitor. Higher potential of crack Lower potential of crack Bending → Twist 5.2 There is a potential of crack if board is warped due to excessive load by check pin ○ ╳ Check pin Support Pin Check pin Page : 14/15 MULTILAYER CERAMIC CHIP CAPACITORS HVC-008-0807 5.3 Mechanical stress due to warping and torsion. (a) Crack occurrence ratio will be increased by manual separation. (b) Crack occurrence ratio will be increased by tensile force , rather than compressive force. ○ :Compressive Stress ╳ :Tensile Stress 6. Handling of Loose Chip Capacitor 6.1 If dropped the chip capacitor may crack. Crack Floor 6.2 In piling and stacking of the P.C. boards after mounting for storage or handling, the corner of the P.C. board may hit the chip capacitor mounted on another board to cause crack. P.C.B Crack 7. Safekeeping condition and period For safekeeping of the products, we recommend to keep the storage temperature between +5 to +40°C and under humidity of 20 to 75% RH. The shelf life of capacitors is 6 months. Page : 15/15
