Acidic flux (with chlorine content exceeding 0.2wt %) and water-soluble flux are forbidden. 1-3 焊接温度及要求 Soldering Temperature & Requirements （a）回流焊 Reflow Soldering 回流焊温度曲线 Reflow Soldering Temperature Profile 回流焊要求 Reflow Soldering Requirements 标准温度曲线 Standard Profile 加热 Heating 加热 时间 Temp.

At the same time, too large a pad area (the line division sections "c" and "d" in the figure) will also cause electrode floating and electrode leaching. Use the recommended pads, otherwise inductor performance may change or position shifts may occur during the soldering process. 6/9 深圳振华富电子有限公司 Shenzhen Zhenhuafu Electronics Co., Ltd. 焊盘布局图 Pad Sketch （b）磁耦合 Magnetic Coupling 由于一些电感器的结构如同开放磁路，电感器之间的间距过窄可能会导致磁耦合，如下图所 示，因此建议使用耦合系数小的电感器。 Since some inductors are structured like open magnetic circuits, too narrow a spacing between inductors may cause magnetic coupling, as shown in the figure below, so it is recommended to use inductors with small coupling coefficients. 磁耦合示意图 Magnetic Coupling Sketch （c）PCB 设计 PCB Design PCB 板需合理设计，使产品不会因板的翘曲而承受机械应力。 PCB needs to be reasonably designed so that the product will not be subjected to the mechanical stress due to warpage of the board, as shown in the figure below. PCB 设计示意图 PCB Design Sketch （d）绑定胶量 Amount of Adhesive 电感器安装后有振动等特殊使用条件时，需对电感器进行粘接绑定。如果绑定胶使用过多， 可能会溢出流入到焊盘或电极处，造成可焊性降低。反之，如果绑定胶用量不足，或者绑定 胶没有充分固化，电感器可能就会在后续试验中脱落，绑定如下图所示。 When the inductor needs to be used in special conditions such as vibration after it is installed, it is necessary to bond the inductor with adhesive. If too much adhesive is applied, then it may overflow 7/9 深圳振华富电子有限公司 Shenzhen Zhenhuafu Electronics Co., Ltd. into the pad or electrode areas and cause poor solder ability. In contrast, if insufficient adhesive is applied, or if the adhesive is not sufficiently hardened, then the inductors may become detached during flow test. The application method of adhesive is shown in the figure below. 绑定示意图 Adhesive Sketch 1-5 清洗 Cleaning 清洗时应遵循以下条件： The following conditions should be observed when cleaning: 电装后建议采用喷淋清洗方式，请勿使用超声清洗。 It is recommended to use spray cleaning method after soldered. Do not use Ultrasonic cleaning. 清洗温度应不高于 60°C（使用醇类有机溶剂时应在 40°C 以下） 。 Cleaning temperature shall be limited to 60°C max. (40°C max for alcohol cleaning agents). 确保彻底清除残留助焊剂，用去离子水清除水溶性清洗液后，应使电感器完全干燥。 To ensure that flux residue is completely removed. Inductors should be thoroughly dried after it has been removed with deionized water. 8/9 深圳振华富电子有限公司 Shenzhen Zhenhuafu Electronics Co., Ltd. 附件 2：最小起定量和其他要求 Annex 2: Minimum Order Quantity and Other Requirements 系列 包装 最小起定量 外箱 Series Packing Minimum Order Quantity Outer Case SMRH3D28 卷盘 Reel 2000 PCS 纸箱 Carton △ 警告 Caution 限制使用 Limitation of Applications 若将本目录中的产品用于需要极高可 飞机设备 Aircraft equipment 靠性以防直接危及第三方生命、身体 运输设备（汽车、火车、船舶等）Transportation equipment (vehicles, trains, ships, etc.) 或财产的下列用途时，或当其中产品 宇航设备 Aerospace equipment 用于本目录规定以外的用途时，请提 交通信号设备 Traffic signal equipment 前与我公司联系。 海底设备 Undersea equipment Please contact us before using our 防灾、预防犯罪设备 Disaster prevention / crime prevention equipment products for the applications listed 电厂设备 Power plant control equipment below which require especially high 数据处理设备 Data-processing equipment reliability for the prevention of defects 医疗设备 Medical equipment which might directly cause damage to 与上述用途具有类似复杂性或有可靠性要求的其它用途。 the third party's life, body or property.
