Caution 2.Information before mounting 1. Do Not re-use capacitors that were removed from the equipment. 2. Confirm capacitance characteristics under actual applied voltage. 3. Confirm the mechanical stress under actual process and equipment use. 4. Confirm the rated capacitance, rated voltage and other electrical characteristics before assembly. 5. Prior to use, confirm the Solderability for the capacitors that were in long-term storage. 6. Prior to measuring capacitance, carry out a heat treatment for capacitors that were in long-term storage. 7.The use of Sn-Zn based solder will deteriorate the reliability of the MLCC. Please contact our sales representative or product engineers on the use of Sn-Zn based solder in advance. 3.Maintenance of the Mounting (pick and place) Machine 1. Make sure that the following excessive forces are not applied to the capacitors. 1-1. In mounting the capacitors on the printed circuit board, any bending force against them shall be kept to a minimum to prevent them from any bending damage or cracking. Please take into account the following precautions and recommendations for use in your process. (1) Adjust the lowest position of the pickup nozzle so as not to bend the printed circuit board. (2) Adjust the nozzle pressure within a static load of 1N to 3N during mounting. 　[Incorrect] Suction Nozzle Deflection Board Board Guide 　[Correct] Support Pin 2.Dirt particles and dust accumulated between the suction nozzle and the cylinder inner wall prevent the nozzle from moving smoothly. This imposes greater force upon the chip during mounting, causing cracked chips. Also the locating claw, when worn out, imposes uneven forces on the chip when positioning, causing cracked chips. The suction nozzle and the locating claw must be maintained, checked and replaced periodically. JEMCGC-01497A 16 ! Caution 4-1.Reflow Soldering 1. When sudden heat is applied to the components, the mechanical strength of the components will decrease because a sudden temperature change causes deformation inside the components. In order to prevent mechanical damage to the components, preheating is required for both the components and the PCB board. Preheating conditions are shown in table 1. It is required to keep the temperature differential between the solder and the components surface (ΔT) as small as possible. [Standard Conditions for Reflow Soldering] Infrared Reflow Temperature(℃) 200℃ 170℃ 150℃ 130℃ 2. Solderability of Tin plating termination chips might be deteriorated when a low temperature soldering profile where the peak solder temperature is below the melting point of Tin is used. Please confirm the Solderability of Tin plated termination chips before use. 3. When components are immersed in solvent after mounting, be sure to maintain the temperature difference (ΔT) between the component and the solvent within the range shown in the table 1.

Too little solder paste results in a lack of adhesive strength on the outer electrode, which may result in chips breaking loose from the PCB. 4-3. Make sure the solder has been applied smoothly to the end surface to a height of 0.2mm* min. Inverting the PCB JEMCGC-01497A Make sure not to impose any abnormal mechanical shocks to the PCB. 17 Caution ! 4-2.Correction with a Soldering Iron 1. When sudden heat is applied to the components when using a soldering iron, the mechanical strength of the components will decrease because the extreme temperature change can cause deformations inside the components. In order to prevent mechanical damage to the components, preheating is required for both the components and the PCB board. Preheating conditions, (The "Temperature of the Soldering Iron tip", "Preheating Temperature", "Temperature Differential" between the iron tip and the components and the PCB), should be within the conditions of table 2. It is required to keep the temperature differential between the soldering Iron and the component surfaces (ΔT) as small as possible. 2. After soldering, do not allow the component/PCB to rapidly cool down. 3. The operating time for the re-working should be as short as possible. When re-working time is too long, it may cause solder leaching, and that will cause a reduction in the adhesive strength of the terminations.

ΔT≦190℃ Air *Applicable for both Pb-Sn and Lead Free Solder. Pb-Sn Solder: Sn-37Pb Lead Free Solder: Sn-3.0Ag-0.5Cu 4. Optimum Solder amount when re-working with a Soldering lron 4-1. In case of sizes smaller than 0603, (GC□18), the top of the solder fillet should be lower than 2/3's of the thickness of the component or 0.5mm whichever is smaller. In case of 0805 and larger sizes, (GC□21), the top of the solder fillet should be lower than 2/3's of the thickness of the component. If the solder amount is excessive, the risk of cracking is higher during board bending or under any other stressful condition. Solder Amount in section 4-2. A Soldering iron with a tip of ø3mm or smaller should be used. It is also necessary to keep the soldering iron from touching the components during the re-work. 4-3. Solder wire with ø0.5mm or smaller is required for soldering. 4-3.Leaded Component Insertion 1. If the PCB is flexed when leaded components (such as transformers and ICs) are being mounted, chips may crack and solder joints may break. Before mounting leaded components, support the PCB using backup pins or special jigs to prevent warping. JEMCGC-01497A 18 ! Caution 5.Washing Excessive ultrasonic oscillation during cleaning can cause the PCBs to resonate, resulting in cracked chips or broken solder joints. Take note not to vibrate PCBs. 6.Electrical Test on Printed Circuit Board 1. Confirm position of the support pin or specific jig, when inspecting the electrical performance of a capacitor after mounting on the printed circuit board. 1-1. Avoid bending printed circuit board by the pressure of a test pin, etc. The thrusting force of the test probe can flex the PCB, resulting in cracked chips or open solder joints. Provide support pins on the back side of the PCB to prevent warping or flexing. 1-2. Avoid vibration of the board by shock when a test pin contacts a printed circuit board. □ Not recommended □ Recommended ← Support pin ← Peeling ← Test-pin JEMCGC-01497A ← Test-pin 19 ! Caution 7.Printed Circuit Board Cropping 1. After mounting a capacitor on a printed circuit board, do not apply any stress to the capacitor that is caused by bending or twisting the board. 1-1. In cropping the board, the stress as shown right may cause the capacitor to crack. Try not to apply this type of stress to a capacitor. Bending Twisting 2. Check of the cropping method for the printed circuit board in advance. 2-1. Printed circuit board cropping shall be carried out by using a jig or an apparatus to prevent the mechanical stress which can occur to the board. (1) Example of a suitable jig Recommended example: the board should be pushed as close to the near the cropping jig as possible and from the back side of board in order to minimize the compressive stress applied to capacitor. Not recommended example* when the board is pushed at a point far from the cropping jig and from the front side of board as below, the capacitor may form a crack caused by the tensile stress applied to capacitor.

Remarks Failure to follow the cautions may result, worst case, in a short circuit and smoking when the product is used. The above notices are for standard applications and conditions. Contact us when the products are used in special mounting conditions. Select optimum conditions for operation as they determine the reliability of the product after assembly. The data herein are given in typical values, not guaranteed ratings. JEMCGC-01497A 21 Notice ■ Rating 1.Operating Temperature 1. The operating temperature limit depends on the capacitor. 1-1.Do not apply temperatures exceeding the upper operating temperature. It is necessary to select a capacitor with a suitable rated temperature which will cover the operating temperature range. Also it is necessary to consider the temperature distribution in equipment and the seasonal temperature variable factor. 1-2.Consider the self-heating of the capacitor The surface temperature of the capacitor shall be the upper operating temperature or less when including the self-heating factors. 2.Atmosphere surroundings (gaseous and liquid) 1. Restriction on the operating environment of capacitors. 1-1. The capacitor, when used in the above, unsuitable, operating environments may deteriorate 　due to the corrosion of the terminations and the penetration of moisture into the capacitor. 1-2. The same phenomenon as the above may occur when the electrodes or terminals of the capacitor are subject to moisture condensation. 1-3. The deterioration of characteristics and insulation resistance due to the oxidization or corrosion of 　　 terminal electrodes may result in breakdown when the capacitor is exposed to corrosive or volatile gases or solvents for long periods of time. 3.Piezo-electric Phenomenon 1. When using high dielectric constant type capacitors in AC or pulse circuits, the capacitor itself vibrates at specific frequencies and noise may be generated. Moreover, when the mechanical vibration or shock is added to capacitor, noise may occur. JEMCGC-01497A 22 Notice ■ Soldering and Mounting 1.PCB Design 1. Notice for Pattern Forms 1-1. Unlike leaded components, chip components are susceptible to flexing stresses since they are mounted directly on the substrate. They are also more sensitive to mechanical and thermal stresses than leaded components. Excess solder fillet height can multiply these stresses and cause chip cracking. When designing substrates, take land patterns and dimensions into consideration to eliminate the possibility of excess solder fillet height. 1-2. It is possible for the chip to crack by the expansion and shrinkage of a metal board. Please contact us if you want to use our ceramic capacitors on a metal board such as Aluminum.

Land Dimensions 2-1. Chip capacitor can be cracked due to the stress of PCB bending / etc if the land area is larger than needed and has an excess amount of solder. Chip Capacitor Land C a b Please confirm the suitable land dimension by evaluating of the actual SET / PCB.

Please evaluate a capacitor by actual cleaning equipment and condition surely for confirming the quality and select the applicable solvent. 2. Unsuitable cleaning solvent may leave residual flux, other foreign substances, causing deterioration of electrical characteristics and the reliability of the capacitors. 3. Select the proper cleaning conditions. 3-1. Improper cleaning conditions (excessive or insufficient) may result in the deterioration of the performance of the capacitors. 3.Coating 1. A crack may be caused in the capacitor due to the stress of the thermal contraction of the resin during curing process. The stress is affected by the amount of resin and curing contraction. Select a resin with small curing contraction. The difference in the thermal expansion coefficient between a coating resin or a molding resin and capacitor may cause the destruction and deterioration of the capacitor such as a crack or peeling, and lead to the deterioration of insulation resistance or dielectric breakdown. Select a resin for which the thermal expansion coefficient is as close to that of capacitor as possible. A silicone resin can be used as an under-coating to buffer against the stress. 2. Select a resin that is less hygroscopic. Using hygroscopic resins under high humidity conditions may cause the deterioration of the insulation resistance of a capacitor. An epoxy resin can be used as a less hygroscopic resin. ■ Others 1.Transportation 1. The performance of a capacitor may be affected by the conditions during transportation. 1-1. The capacitors shall be protected against excessive temperature, humidity and mechanical force during transportation. (1) Climatic condition － low air temperature：－40℃ － change of temperature air/air：－25℃/＋25℃ － low air pressure：30 kPa － change of air pressure：6 kPa/min (2) Mechanical condition Transportation shall be done in such a way that the boxes are not deformed and forces are not directly passed on to the inner packaging. 1-2. Do not apply excessive vibration, shock, and pressure to the capacitor. (1) When excessive mechanical shock or pressure is applied to a capacitor, chipping or cracking may occur in the ceramic body of the capacitor. (2) When a sharp edge of an air driver, a soldering iron, tweezers, a chassis, etc. impacts strongly on the surface of capacitor, the capacitor may crack and short-circuit. 1-3. Do not use a capacitor to which excessive shock was applied by dropping etc. The capacitor dropped accidentally during processing may be damaged.
