Reference Only SpecNo.JEFK243A-0001H-01 P6/9 12. Notice Products can only be soldered with reflow. This product is designed for solder mounting. Please consult us in advance for applying other mounting method such as conductive adhesive. 12.1 Flux and Solder Flux Use rosin-based flux, (with converting chlorine content 0.06 to 0.1(wt)%. ), but not highly acidic flux (with Halogen content exceeding 0.2(wt)% conversion to chlorine). Do not use water-soluble flux. Solder Use Sn-3.0Ag-0.5Cu solder 12.2 Assembling <Exclusive use of Reflow soldering> Flow soldering may cause deterioration in insulation resistance. So, reflow soldering shall be applied for this product. 12.3 Cleaning Conditions Do not clean after soldering. Some cleaning agents may degrade bonding strength,and characteristics of products by detaching. If cleaning,please contact us. 12.4 Resin coating The electrical performance 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. 12.5 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 due to warping the board. [Products direction] Products shall be location the sideways a Direction (Length : a<b) to the mechanical b 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 Perforatio n B *1 A > D is valid when stress is added vertically to the perforation as D with Hand Separation. A If a Cutting Disc is used, stress will be diagonal to the PCB, Slit therefore A > D is invalid. MURATA MFG.CO., LTD

Reference Only SpecNo.JEFK243A-0001H-01 P7/9 (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 12.6 Attention Regarding P.C.B. Design Portionof Perforation < The Arrangement of Products > P.C.B. shall be designed so that products are far from the portion P.C.B. × ○ of perforation. ○ Product The portion of perforation shall be designed as narrow as possible Portionof × and shall be designed so as not to be applied the stress in the case Perforation of P.C.B. separation. Products shall not be arranged on the line of a series of holes when there are big holes in P.C.B. (Because the stress concentrate on the P.C.B. ○ × line of holes.) Product Hole < Products Placing > Support pins shall be set under P.C.B . to prevent causing a warp to P.C.B. during placing the products on the other side of P.C.B. Pick-upnozzle < P.C.B. Separation > Product P.C.B. shall not be separated with hand. P.C.B. shall be separated with the fixture so as not to cause P.C.B. bending. P.C.B. Supportpin 12.7 Standard Land Dimensions (Reflow) ∗2 4 0. ∗1 2 1. ∗3 Resist 0.8 Copperfoilpattern 2.6 Nopattern (inmm) ∗ 1 If the pattern is made with wider than 1.2mm. It will result to let component turn around, because melting speed is different. In the worst case, short circuit between lines may be occured. ∗ 2 If the pattern is made with less than 0.4mm , in the worst case , short circuit between lines may be occurred deu to the spread of soldering paste or mount placeing accuracy. ∗ 3 If the pattern is made with wider than 0.8mm, the strength of bending will be reduced. ∗ 4 Do not use gilded pattern. A copper wire may cause open by dissolution of metallization. 12.8 Standard Soldering Condition 1. Reflow Soldering (1) Standard printing pattern for soldering. • Standard thickness of the solder paste should be 100 to 150µm. 0.51.2 • Use the solder paste printing pattern of the right pattern. • For the resist and copper foil pattern, use standard land dimensions. • Use the Solder Sn-3.0Ag-0.5Cu for pattern printing. • Spread of soldering paste between lines may cause short circuit of lines. 0.8 2.6 (inmm) MURATA MFG.CO., LTD

Reference Only SpecNo.JEFK243A-0001H-01 P8/9 (2) Soldering Temperature Temperature difference between soldering and surface of components must be within 150°C, in preheating. When components are immersed in liquid after soldering, temperature difference should be within 100°C. If preheating is not enough, components may be cracked and cause deterioration in insulation resistance. (3) Soldering Condition 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. Temp. 260℃/10s (℃) 245±3℃ 230℃ 220℃ Limit Profile 180 150 Standard Profile 30~60s 60s max. 90s±30s Time(s) Standard Profile Limit Profile Pre-heating 150~180°C 、90s±30s Heating above 220°C、30s~60s above 230°C、60s max. Peak temperature 245±3°C 260°C、10s Cycle of reflow 2 times 2 times 2. Reworking with Soldering iron The following conditions must be strictly followed when using a soldering iron after being mounted by reflow soldering. · Pre-heating: 150°C, 1 min · Soldering iron output: 30W max. · Tip temperature: 350°C max. · Tip diameter:φ3mm max. · Soldering time : 3(+1,-0) seconds. · Times : 2times max. Notes: Do not touch the products directly with the soldering iron. 3. Solder Volume Solder shall be used not to be exceeded the upper limits as shown below. Upperlimit Recommendable t T 1/3T≦t≦T(T:Ticknessofelectrode) 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. MURATA MFG.CO., LTD
