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. 14.1 Flux and Solder Flux Solder 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. Use Sn-3.0Ag-0.5Cu solder MURATA MFG CO., LTD. Reference Only Spec No. JEFL243C-0040E-01 P 7/10 14.2 Assembling < Exclusive use of Reflow soldering > Flow soldering may cause deterioration in insulation resistance. So,reflow soldering shall be applied for this product. < Thermal Shock > Pre-heating should be in such a way that the temperature difference between solder and ceramic surface is limited to 100°C max. Also cooling into solvent after soldering should be in such a way that the temperature difference is limited to 100°C max. Not enough preheating may cause deterioration in insulation resistance and / or crank or ceramic body. 14.3 Cleaning Conditions Do not clean after soldering. 14.4 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. 14.5 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b) to the mechanical stress. 〈 Good example 〉 (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 (1) Turn the mounting direction of the component parallel to the board separation surface. (2) Add slits in the board separation part. (3) Keep the mounting position of the component away from the board separation surface. Perforation A Stress Level A > D *1 A > B A > C C B D 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 MURATA MFG CO., LTD. Reference Only Spec No. JEFL243C-0040E-01 P 8/10 Portion of Perforation 14.6 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. •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. × P.C.B. ○ ○ Portion of Perforation •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.) 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. Separation > •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.
