Notice This product is designed for solder mounting. Please consult us in advance for applying other mounting method such as conductive adhesive. 16.1 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 MURATA MFG.CO.,LTD Spec No. JEFL243C-0002W-01 P6/9 16.2 Assembling Products can only be soldered with reflow. Flow soldering may cause deterioration in insulation resistance. So,reflow soldering shall be applied for this product. 16.3 Claening Conditions Do not clean after soldering. Some cleaning agents may degrade bonding strength,and characteristics of products by detaching. If cleaning,please contact us. 16.4 Resin coating The impedance 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. 16.5 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］ a b 〈 Poor example〉 Products shall be location the sideways Direction (Length : 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 Perforation C 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. MURATA MFG.CO.,LTD Spec No. JEFL243C-0002W-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 16.6 Attention Regarding P.C.B. Design < The Arrangement of Products > P.C.B. shall be designed so that products are far from the portion of perforation. Portion of Perforation × P.C.B. The portion of perforation shall be designed as narrow as possible, and shall be designed so as not to be applied the stress in the case 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 line of holes.) ○ ○ Portion of Perforation Product × ○ P.C.B. × 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- up nozzle Product P.C.B. < P.C.B. Separation > Support pin 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. 1.6 1 0.4 16.7 Standard Land Dimensions (Reflow) 2 1.6 3.7 Resist Copper foil pattern No Pattern (in mm) 1 If the pattern is made with wider than 1.6mm. 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 wider than 1.6mm, the strength of bending will be reduced. 3 Do not use gilded pattern. A copper wire may cause open by dissolution of metallization.
