multilayer ceramic capacitor
multilayer ceramic capacitor - 1 - introduction mlcc(multilayer ceramic capacitor) is smd(surfa ce mounted device) type capacitor that is used in wide ranges of capacitance. mlcc is paid more attentions than other capacitors due to the better frequency characteristics, higher reliability, higher withstanding voltage and so on. mlcc is made of many layers of ceramic and inner electrodes like sandwich. pd was used for inner electrodes. but the price of pd was skyr ocketed and pd was rep laced by the bme(base metal electrode), which reduced the total cost of mlcc. this inner electrode is connected to outer termination for surface mounting, which is composed of three layers, cu or ag layer, ni plating layer, and snpb or sn plating layer. most of mlccs become pb free by the environmental issue at present. mlcc is divided into two classes. class i(c0g, etc) is the temperature compensating type. it has a small tcc(temperature coefficient of capacitance) and a better frequency performance. therefore, it is used in rf applications such as cellular phone, tuner, and so on. class ii(x7r, x5r, y5v, etc) is the high dielectric constant type, which is used in general electronic circuit. especially high capacitance mlcc is replacing other capacitors (tantalum and aluminum capacitor) due to the low esr(equivalent series resistance) value. feature and application feature -miniaturesize - wide capacitance and voltage range - highly reliable performance - tape & reel for surface mount assembly - low esr - high q at high frequencies - stable temperature dependence of capacitance application - high frequency circuit(tuner, vco, pam etc) - general power supply circuit(smps etc) - dc-dc converter - general electronic circuit

multilayer ceramic capacitor - 27 - application manual storage condition ? storage environment the electrical characteristics of mlccs were degraded by the environment of high temperature or humidity. 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 gase s, mlccs must be avoid from these gases. ? temperature fluctuations since dew condensation may occur by the differences in temperature when the mlccs are taken out of storage, it is important to maintai n the temperature-controlled environment. 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, i f 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 w b a solder land solder resist 2/3w < b < w t solder resist 2/3t < a < t 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.
multilayer ceramic capacitor - 28 - 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. ? adhesive hardening characteristics to prevent oxidation of the terminations, the adhesive must harden at 160 or less, within 2 minutes or less. mounting ? mounting head pressure excessive pressure will cause crack to mlccs . the pressure of nozzle will be 300g maximum during mounting. ? 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. support pin force nozzle flux although the solderability increased by the highly-activated flux, increase of activity in flux may also degrade the insulation of the chip capacitors. to avoid such degradation, it is recommended that a mildly activated rosin flux(less than 0.2% chlorine) be used.
multilayer ceramic capacitor - 29 - soldering since a multilayer ceramic chip capacitor comes into direct contact with melted solder during soldering, it is exposed to potentially mechanical stress caused by the sudden temperature change. the capacitor may also be subject to silver migration, and to contamination by the flux. because of these factors, soldering technique is critical. ? soldering methods method classification reflow soldering - overall heating - infrared rays - hot plate - vps(vapor phase) - local heating - air heater -laser - light beam flow soldering - single wave - double wave - * we recommend the reflow soldering method. ? soldering profile to avoid crack problem by sudden temperature change, follow the temperature profile in the adjacent graph. 300 250 200 150 100 50 preheating soldering cooling 60~120sec 10~20sec reflow soldering 300 250 200 150 100 50 preheating soldering cooling t 150 60~120sec 3~4sec flow soldering ? manual soldering manual soldering can pose a great risk of creating thermal cracks in chip capacitors. the hot soldering iron tip comes into direct contact with t he 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.
multilayer ceramic capacitor - 30 - ? amount of solder too much solder not enough solder cracks tend to occur due to large stress weak holding force may cause bad connections or detaching of the capacitor good ? cooling natural cooling using air is recommended. if the chips are dipped into solvent for cleaning, the temperature difference( t) must be less than 100 6-6. cleaning if rosin flux is used, cleaning usually is unnecessary. when strongly activated flux is used, chlorine in the flux may dissolve into some type s of cleaning fluids, th ereby 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 of the circuit board.
