Besides, to ensure packing material’s good state, packages must be stored at -10℃ to 40℃ and 70% RH Max. (2) The solderability of the external electrodes may deteriorate if packages are exposed to dust of harmful gas (e.g. HCl, sulfurous gas of H2S). (3) Packaging materials may deform if packages are exposed directly to sunlight. (4) Minimum packages, such as polyvinyl heat-seal packages shall not be opened until they are used. If opened, use the reels as soon as possible. (5) Solderability shall be guaranteed for a period of time from the date of delivery on condition that they are stored at the specified environment. For those parts, which passed more than the time shall be checked solderability before using. (6) For magnetic products, keep clear of anything that may generate magnetic fields to avoid change of products performance. (7) To avoid any damage to products, do not load mechanic force on products or place heavy goods on products, and exclude strong vibration or drop. (8)In case of storage over 12 months, solderability shall be checked before actual usage. 7. Warning and Attentions 7.1 Precautions on Use (1) Always wear static control bands to protect against ESD. (2) Any devices used with the products (soldering irons, measuring instruments) should be properly grounded. (3) Keep bare hands and metal conductors (i.e., metal desk) away from electrodes or conductive areas that lead to electrodes. (4) Preheat when soldering. (5) Don’t apply current in excess of the rated current value. It may reduce the impedance or inductance, or cause damage to components due to over-current. (6) For magnetic products, keep clear of anything that may generate magnetic fields such as speakers and coils. Use non-magnetic tweezers when handing the chips. (7) When soldering, the electrical characteristics may be varied due to hot energy and mechanical stress. (8) When coating products with resin, the relatively high resin curing stress may change the electrical characteristics. For exterior coating, select resin carefully so that electrical and mechanical performance of the product is not affected. Before using, please evaluate reliability with the product mounted in your application set. (9) When mount chips with adhesive in preliminary assembly, do appropriate check before the soldering stage, i.e., the size of land pattern, type of adhesive, amount applied, hardening of the adhesive on proper usage and amounts of adhesive to use. (10) Mounting density: Add special attention to radiating heat of products when mounting other components nearby. The excessive heat by other products may cause deterioration at joint of this product with substrate. (11) Since some products are constructed like an open magnetic circuit, narrow spacing between components may cause magnetic coupling. (12) Please do not give the product any excessive mechanical shocks in transportation. (13) Please do not touch wires by sharp terminals such as tweezers to avoid causing any damage to wires. (14) Please do not add any shock and power to the soldered product to avoid causing any damage to chip body. Sunlord Categories: general confidential Specifications for Wire Wound Molded SMD Power Inductors Page 7 of 28 (15) Please do not touch the electrodes by naked hand as the solderability of the external electrodes may deteriorate by grease or oil on the skin. 7.2 PCB Bending Design The following shall be considered when designing and laying out PCB’s. (1) PCB shall be designed so that products are not subjected to the mechanical stress from board warp or deflection. Products shall be located in the sideways direction to the mechanical stress (Poor example) (Good example) (2) Products location on PCB separation. Seam B A C Product shall be located carefully because they may be subjected to the mechanical stress in order of A>C=B>D. D (3) When splitting the PCB board, or insert (remove) connector, or fasten thread after mounting components, care is required so as not to give any stress of deflection or twisting to the board. Because mechanical force may cause deterioration of the bonding strength of electrode and solder, even crack of product body. Board separation should not be done manually, but by using appropriate devices. 7.3 Recommended PCB Design for SMT Land-Patterns When chips are mounted on a PCB, the amount of solder used (size of fillet) can directly affect chip performance. Therefore, the following items must be carefully considered in the design of solder land patterns: (1) The amount of solder applied can affect the ability of chips to withstand mechanical stresses which may lead to breaking or cracking. Therefore, when designing land-patterns it is necessary to consider the appropriate size and configuration of the solder pads which in turn determines the amount of solder necessary to form the fillets. (2) When more than one part is jointly soldered onto the same land or pad, the pad must be designed that each component’s soldering point is separated by solder-resist. Recommended land dimensions please refer to product specification. 8 Recommended Soldering Technologies 8.1Re-flowing Profile: △ Preheat condition: 150 ~200℃/60~120sec. △ Allowed time above 217℃: 60~90sec. △ Max temp: 260℃ △ Max time at max temp: 10sec. △ Solder paste: Sn/3.0Ag/0.5Cu △ Allowed Reflow time: 2x max Please refer to Fig. 8.1 217℃ Max Ramp Up Rate=3℃/sec.
