PRECAUTIONS AND RECOMMENDED SOLDERING CONDITIONS FOR USING DIELECTRIC FILTERS

SURFACE MOUNT TYPE

表面贴装型介质滤波器的使用注意事项和推荐焊接条件

1. Reflow solder conditions

•Solderability

When flux-mounted terminals are immersed in

solder at following conditions, at least 95% of the

surface should be covered by solder.

Conditins

leaded process : 215±5°C for 3±0.5 seconds

lead free process : 245±5°C for 3±0.5 seconds

•Solder heat resistance

No abnomalities under solder conditions of

leaded process : 230±5°C for 5 seconds

lead free process : 255±5°C for 5 seconds

2. Rinsing

After Soldering, you should rinsing away the

excess flux. Any commercially available rinsing

agent may be used.

3. Other Precautions

Perform soldering at as low a temperature as

possible and for as short a time as possible.

Make sure that the silver electrode of resonators

is not covered by solder.

Avoid applying external forces to terminals such

as by bending or cutting them.

4. Iron Soldering

Perform iron soldering with iron at following

conditions.

Conditins

leaded process : 350°C for 5s. Max.

lead free process : 390±5°C for 5s. Max.

1. 回流焊接条件

・可焊性

焊装的端子在以下条件下浸入焊剂时，至少95%的表面应

被焊剂覆盖。

条件

有铅焊接：230±5°C下3±0.5秒

无铅焊接：260±5°C下3±0.5秒

・焊剂耐热性

在以下焊料条件下无异常：

有铅焊接：230±5°C下5秒

无铅焊接：260±5°C下5秒

2. 清除

焊接后，应清除多余的焊剂。

可使用市面上可买到的任意一款水洗剂。

3. 其他注意事项

在尽可能低的温度下用尽可能少的时间进行焊接操作。

确保振荡器的银质电极没有被焊剂覆盖。

避免对端子施加其他力量，如弯曲或切割等。

4. 烙铁焊接

当烙铁处于以下状态时进行烙铁焊接操作。

条件

有铅焊接：350±5°C下最多5秒

无铅焊接：390±5°C下最多5秒
