附件 1:电感器焊接及安装注意事项
Annex 1: Inductors Soldering and Mounting Precautions
1-1 焊接方式 Soldering Methods
(a)贴片电感器推荐使用回流焊。
Reflow soldering is recommended for Chip Inductors.
(b)插件电感器推荐使用波峰焊或者烙铁焊。
Flow soldering or soldering iron is recommended for through-hole Inductors.
(c)条件限制时除外。
Except for limited conditions.
1-2 焊接原材料 Soldering Materials
(a)焊料:推荐使用 96.5Sn/3.0Ag/0.5Cu 焊料,或者采用 Sn 含量不超过 97%的锡合金焊料。
Solder: It is recommended to use 96.5Sn/3.0Ag/0.5Cu solder, or use Tin alloy solder with a Tin
content not exceeding 97%.
(b)助焊剂:推荐使用松香类助焊剂,请勿使用强酸性助焊剂(含氯量超过 0.2wt %),并且请勿
使用水溶性助焊剂。
Flux: It is recommended to use rosin-based flux. Acidic flux (with chlorine content exceeding
0.2wt %) and water-soluble flux are forbidden.

(c)烙铁焊 Soldering Iron
推荐使用恒温电烙铁进行焊接,焊头工作部分最大直径不宜超过 5 毫米。
It’s recommended to use a constant temperature soldering iron, the maximum diameter of the
soldering iron end tip should not exceed 5 mm.
焊接温度根据焊料和实际情况确定,最高温度不宜超过 380℃。
The temperature of soldering iron is determined according to the solder and the actual situation, and
the maximum temperature should not exceed 380 °C.
单次焊接时间应控制在 3 秒以内。
The single soldering time should be controlled within 3 seconds.
重焊或者重复焊接时,需先在 150℃条件下预热 1-2 分钟。
When resoldering or repeating the soldering, it is necessary to preheat for 1-2 minutes at 150 °C.
烙铁头不能直接接触元件焊盘以外的部分。
Do not directly touch parts other than soldering pads with soldering iron tip.
1-4 安装说明 Mounting instructions
(a)焊盘布局尺寸 Pad Dimensions
过大焊盘会降低安装后的电感器 Q 值。同时,过大焊盘面积(图中线划分部分“c”和“d”)
还会造成电极浮悬和电极浸出。请采用推荐焊盘,否则电感器性能可能发生变化或者在焊接
过程中出现位置偏移。
Too large a pad can degrade the inductor Q value after installation. 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.

(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

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.
