Soldering time 3(+1,-0)s Times 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. 10.5 Solder Volume ・Solder shall be used not to be exceeded 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. Upper Limit Recommendable T t 1/3T≦t≦T T: Lower flange thickness 10.6 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 b 〈 Poor example〉 Products shall be located in the sideways direction (Length:a B (3) Keep the mounting position of the component away from the board separation surface. A > C b A C B Seam D Slit > D ∗1 ∗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. 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 in a position as far away from the screw holes as possible. Screw Hole Recommended 10.7 Cleaning Conditions Products shall be cleaned on the following conditions. (1) Cleaning temperature shall be limited to 60°C max.(40°C max for alcohol type cleaner.) (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.

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. 10.8 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. 10.9 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 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.
