Solder Use Sn-3.0Ag-0.5Cu solder Standard thickness of solder paste : 100 µm to 200 μm (2) Soldering conditions • Pre-heating should be in such a way that the temperature difference between solder and ferrite surface is limited to 150℃ max. Also cooling into solvent after soldering should be in such a way that the temperature difference is limited to 100℃ max. Insufficient pre-heating may cause cracks on the ferrite, resulting in the deterioration of product 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.

UpperLimit Recommendable t 1/3T≦t≦T (T:Chip thickness) Accordingly increasing the solder volume, the mechanical stress to product is also increased. Exceeding solder volume may cause the failure of mechanical or electrical performance. 10-5.Attention regarding P.C.B. bending 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 for board warpage. <Products direction> a Products shall be located in the sideways b direction (Length:a<b) to the mechanical stress. 〈Poorexample〉 〈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 the board separation surface. A > D *1 (2) Add slits in the board separation part. A > B (3) Keep the mounting position of the component away from the board separation surface. A > C C Perforation B D A Slit *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 the PCB, therefore A > D is invalid. (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 in a position as far away from the screw holes as possible. Screw Hole Recommended 10-6.Mounting density Add special attention to radiating heat of products when mounting the inductor near the products with heating. The excessive heat by other products may cause deterioration at joint of this product with substrate. MURATA MFG.CO.,LTD.

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. 10-10. 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 10-11.Storage Conditions (1)Storage period Use the products within 6 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 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. • Products should be stored under the airtight packaged condition. (3)Delivery Care should be taken when transporting or handling product to avoid excessive vibration or mechanical shock. MURATA MFG.CO.,LTD.
