[incorrect] [correct] 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. caution ! jemccc-0010q 15 board guide board suction nozzle deflection support pin
4-1.reflow soldering 1. when sudden heat is applied to the components, the [standard conditions for reflow soldering] mechanical strength of the components will decrease because a sudden temperature change causes infrared reflow 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 (t) as small as possible. 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. vapor reflow 3. when components are immersed in solvent after mounting, be sure to maintain the temperature difference (t) between the component and the solvent within the range shown in the table 1. table 1 [allowable soldering temperature and time] recommended conditions infrared reflow vapor reflow peak temperature 230 250 230 240 240 260 atmosphere air air air or n 2 pb-sn solder: sn-37pb lead free solder: sn-3.0ag-0.5cu in case of repeated soldering, the accumulated soldering time must be within the range shown above. 4. optimum solder amount for reflow soldering 4-1. overly thick application of solder paste results in a excessive solder fillet height. this makes the chip more susceptible to mechanical and thermal stress on the board and may cause the chips to crack. in section 4-2. 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. make sure not to impose any abnormal mechanical shocks to the pcb. pb-sn solder lead free solder inverting the pcb caution part number temperature differential gnm0m/gnm1m/gnm21/ gnm31 t Q 130 ! jemccc-0010q 16 temperature( ) peak temperature 170 150 130 200 soldering gradual cooling preheating t 60 - 120 seconds 30 - 60 seconds time soldering temperature( ) soldering time(sec.) 280 270 260 250 240 230 220 0 3 0 6 0 12 0 9 0 temperature( ) peak temperature 170 150 130 t soldering gradual cooling preheating time 60 - 120 seconds 20 seconds max. 0.2mm min
4-2.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. 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 caution ! jemccc-0010q 17 test - pin peeling test - pin support pin
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. outline of jig (2) example of a suitable machine an outline of a printed circuit board cropping machine is shown as follows. along the lines with the v-grooves on printed circuit board, the top and bottom blades are aligned to one another when cropping the board. the misalignment of the position between top and bottom blades may cause the capacitor to crack. outline of machine principle of operation cross-section diagram top blade top blade top blade top blade bottom blade bottom blade bottom blade bottom blade caution recommended not recommended top-bottom misalignment left-right misalignment front-rear misalignment recommended not recommended printed circuit board v - groove board cropping jig printed circuit board top blade v - groove bottom blade top blade printed circuit board v - groove ! jemccc-0010q 18 1 a printed circuit board components load point direction of load printed circuit board component s load point direction of load

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. notice jemccc-0010q 20
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.there is a possibility of chip crack caused by pcb expansion/contraction with heat.

because stress for chip is different depend on pcb material and structure.especially metal pcb such as alumina has a greater risk of chip crack because of large difference of thermal expansion coefficient. in case of chip below 0402 size, there is also the same possibility of crack with a single-layered glass epoxy board. pattern forms placing of leaded components after chip component lateral mounting notice prohibited correct placing close to chassis placing of chip components and leaded components jemccc-0010q 21 chassis solder (ground) electrode pattern solder resist lead wire solder resist lead wire soldering iron solder resist ????????? solder resist
