Please consult us in advance for applying other mounting method such as conductive adhesive. 11.1 Land pattern designing Recommended land patterns for reflow soldering are as follows: These have been designed for Electric characteristics and solderability. Please follow the recommended patterns. Otherwise, their performance which includes electrical performance or solderability may be affected, or result to "position shift" in soldering process. ChipCoil Land c Solder resist A 0.6 to 0.8 B 1.9 to 2.0 C 0.7 to 1.0 a (in mm) b 11.2 Flux, Solder ・Use rosin-based flux. Includes middle activator equivalent to 0.06(wt)% to 0.1(wt)% Chlorine. Don’t use highly acidic flux with halide content exceeding 0.2(wt)% (chlorine conversion value). Don’t use water-soluble flux. ・Use Sn-3.0Ag-0.5Cu solder. ・Standard thickness of solder paste : 100μm to 150μm. 11.3 Reflow soldering conditions ・Pre-heating should be in such a way that the temperature difference between solder and product surface is limited to 150°C max. Cooling into solvent after soldering also should be in such a way that the temperature difference is limited to 100°C max. Insufficient pre-heating may cause cracks on the product, resulting in the deterioration of products quality. ・Standard soldering profile and the limit soldering profile is as follows. The excessive limit soldering conditions may cause leaching of the electrode and / or resulting in the deterioration of product quality. ・Reflow soldering profile Temp. 260℃ (℃) 245℃±3℃ 220℃ 230℃ Limit Profile 180 150 30s～60s Standard Profile 60s max. 90s±30s Time.(s) Standard Profile Limit Profile Pre-heating 150°C～180°C 、90s±30s Heating above 220°C､30s～60s above 230°C､60s max.

Reference Only SpecNo.JELF243A-0026Q-01 P.7/9 11.4 Reworking with soldering iron The following conditions must be strictly followed when using a soldering iron. Pre-heating 150°C,1 min Tip temperature 350°C max. Soldering iron output 80W max. Tip diameter φ3mm max. Soldering time 3(+1,-0)s Time 2 times Note：Do not directly touch the products with the tip of the soldering iron in order to prevent the crack on the products due to the thermal shock. 11.5 Solder Volume ・Solder shall be used not to be exceed the upper limits as shown below. ・Accordingly increasing the solder volume, the mechanical stress to Chip is also increased. Exceeding solder volume may cause the failure of mechanical or electrical performance. UpperLimit Recommendable(t) 1/3T≦t≦T T T：thickness of product 11.6 Product’s location The following shall be considered when designing and laying out P.C.B.'s. (1) P.C.B. shall be designed so that products are not subject to the mechanical stress due to warping the board. ［Products direction］ a Products shall be located in the sideways direction (Length:a＜b) to the mechanical b stress. 〈Poor example〉 〈Goodexample〉 (2) Components location on P.C.B. separation. It is effective to implement the following measures, to reduce stress in separating the board. It is best to implement all of the following three measures; however, implement as many measures as possible to reduce stress. Contents of Measures Stress Level (1) Turn the mounting direction of the component parallel to A > D ∗1 the board separation surface. (2) Add slits in the board separation part. A > B (3) Keep the mounting position of the component away from A > C the board separation surface. C Seam B ∗1 A > D is valid when stress is added vertically to the perforation as with Hand Separation. If a Cutting Disc is used, stress will be diagonal to D the PCB, therefore A > D is invalid. b A Slit Length:a<b a (3) Mounting Components Near Screw Holes When a component is mounted near a screw hole, it may be affected by the board deflection that occurs during the tightening of the screw. Mount the component Screw Hole Recommended in a position as far away from the screw holes as possible. MURATA MFG.CO., LTD

Reference Only SpecNo.JELF243A-0026Q-01 P.8/9 11.7 Cleaning Conditions Products shall be cleaned on the following conditions. (1) Cleaning temperature shall be limited to 60°C max.(40°C max for IPA) (2) Ultrasonic cleaning shall comply with the following conditions with avoiding the resonance phenomenon at the mounted products and P.C.B. Power : 20 W / l max. Frequency : 28kHz to 40kHz Time : 5 min max. (3) Cleaner 1. Alcohol type cleaner Isopropyl alcohol (IPA) 2. Aqueous agent PINE ALPHA ST-100S (4) There shall be no residual flux and residual cleaner after cleaning. In the case of using aqueous agent, products shall be dried completely after rinse with de-ionized water in order to remove the cleaner. (5) Other cleaning Please contact us. 11.8 Resin coating The inductance value may change due to high cure-stress of resin to be used for coating/molding products. An open circuit issue may occur by mechanical stress caused by the resin, amount/cured shape of resin, or operating condition etc. Some resin contains some impurities or chloride possible to generate chlorine by hydrolysis under some operating condition may cause corrosion of wire of coil, leading to open circuit. So, please pay your careful attention when you select resin in case of coating/molding the products with the resin. Prior to use the coating resin, please make sure no reliability issue is observed by evaluating products mounted on your board. 11.9 Caution for use ・Sharp material such as a pair of tweezers or other material such as bristles of cleaning brush , shall not be touched to the winding portion to prevent the breaking of wire. ・Mechanical shock should not be applied to the products mounted on the board to prevent the breaking of the core. 11.10 Notice of product handling at mounting In some mounting machines,when picking up components support pin pushes up the components from the bottom of base tape. In this case, please remove the support pin. The support pin may damage the components and break wire. In rare case ,the laser recognition can not recognize this component. Please contact us when you use laser recognition. (There is no problem with the permeation and reflection type.) 11.11 Handling of a substrate After mounting products on a substrate, do not apply any stress to the product caused by bending or twisting to the substrate when cropping the substrate, inserting and removing a connector from the substrate or tightening screw to the substrate. Excessive mechanical stress may cause cracking in the product. Bending Twisting 11.12 Storage and Handing Requirements (1) Storage period Use the products within 12 months after delivered. Solderability should be checked if this period is exceeded. (2) Storage conditions ・Products should be stored in the warehouse on the following conditions. Temperature ： -10°C to 40°C Humidity ： 15% to 85% relative humidity No rapid change on temperature and humidity ・Don't keep products in corrosive gases such as sulfur,chlorine gas or acid, or it may cause oxidization of electrode, resulting in poor solderability. ・Products should not be stored on bulk packaging condition to prevent the chipping of the core and the breaking of winding wire caused by the collision between the products. ・Products should be stored on the palette for the prevention of the influence from humidity, dust and so on. ・Products should be stored in the warehouse without heat shock, vibration, direct sunlight and so on. (3) Handling Condition Care should be taken when transporting or handling product to avoid excessive vibration or mechanical shock. MURATA MFG.CO., LTD
