The example below shows recommendations for better design. 第 19 页 perforation slit magnitude of stress A>B=C>D>E 在沿着分拨线分拨电路板时,对产品施加的机械应力与使用的方法关系很大。分折电路板时片状元件受到的疲劳按照如下顺序增 大:分折、剪切、V型槽、穿孔。因此,贴装时应该考虑电路板的分拨过程。 When breaking PC boards along their perforations, the amount lf mechanical stress on the capacitors can vary according to the method used. The following methods are listed in order from least stressful to most stressful: push-back, silt, -grooving, and perforation. Thus, any ideal SMD capacitor layout must also consider the PCB splitting procedure. 7.2 自动贴装注意事项 Considerations for automatic placement 贴装机的调整 Adjustment of mounting machine ①.产品在电路板贴装时,不应该受到过大的冲击。 ②.必须定期对吸头和定位爪进行检查、维修和更换。 ①. Excessive impact load should not be imposed on the capacitors when mounting the PC boards. ②. The maintenance and inspection of the mounters should be conducted periodically. 项目Item 不推荐结构Not recommended 推荐结构Recommended crack 单面贴装 Single-sided mounting supporting pin crack 双面贴装 Double-sided mounting solder peeling 7.3推荐焊接曲线 crack supporting pin Recommended soldering profile 7.3.1 说明: ① 产品推荐使用回流焊接工艺; ② 大尺寸产品适用于回流焊接工艺。 Re: ①flow Soldering is recommended; ②flow soldering is suitable for bigger size MLCCs. 第 20 页 7.3.2 锡铅焊接曲线 Recommended Sn&Pb soldering profile 再流焊 Reflow soldering preheating over 1 minute over 1 minute 230°C within 10 seconds 注意 Caution ①理想状况的焊锡高度为电容器厚度的1/3 ~1/2,如下图所示: ①The ideal condition is to have solder mass (fillet) controlled to 1/2 to 1/3of the thickness of the capacitor, as shown below: 1/2T-1/3T capacitor T Solder PC board ②过长的焊接时间会影响端头的可焊性, 焊接时间尽可能保持与推荐时间一致。 ②Because excessive dwell times can detrimentally affect solderability, soldering duration should be kept as close to recommended times as possible. 波峰焊 Wave solder profile 注意Caution ①.确保电容器充分预热。 ②.产品预热和焊接温度差不超过100~130℃。 ③.焊接后尽可能慢速冷却。 ①.Make sure the capacitors are preheated sufficiently. ②.The temperature difference between the capacitor and melted solder should not be greater than 100 to 130℃. ③.Cooling after soldering should be gradual as possible. 第 21 页 手工焊接 Hand soldering 注意 Caution ①.用尖端最大直径1.0mm功率20W的焊接烙铁。 ②.焊接烙铁不要直接接触产品。 ①.Use a 20w soldering iron with a maximum tip diameter of 1.0mm. ②.The soldering iron should not directly touch the capacitor. 7.3.3无铅焊接曲线 Recommended Pb-Free soldering profile 回流焊接 Reflow solder 波峰焊接 Wave solder profile 第 22 页 7.4 分拨电路板 Handling Breakaway PC boards (splitting along perforations) ⑴.在电容器或其它贴装后,必须注意因电路板弯曲或变形带来的应力。 ⑵.分拨电路板时必须使用专用的夹具,不可以用手拨断。 ⑴.When splitting the PC board after mounting capacitors and other components, care is required so as not to give any stresses of deflection or twisting to the board. ⑵.Board separation should not be done manually, but by using the appropriate devices. 7.5保存 Storage ⑴.在下列环境中保存产品:温度 5~40℃;湿度 ≤70% RH ⑵.产品自生产之日保存期为一年,产品使用之前请勿拆开编带。 ⑶.编带拆开后,产品应在三个月内使用。 ⑷.高介电常数电容器 (X7R,X5R,Y5V) 的容值随时间会逐渐减小,所以在电路设计时应充分考虑这一现象。容值减小的电容器在 150℃热处理1小时后容值会恢复到初试值。 ⑴. Keep the storage environment conditions as following: Temperature: 5~40℃;Humidity: ≤70% RH ⑵. Don’t open the tape until the parts are to be used, and store them within one year since the date printed on the reel. ⑶. Use the chips within 3 months after the tape is opened. ⑷. The capacitance value of high dielectric constant capacitors (X7R,X5R,Y5V) will gradually decrease with the passage of time, so this should be taken into consideration in the circuit design. If such a capacitance reduction occurs, a heat treatment of 150℃ for 1 hour will return the capacitance to its initial level. 第 23 页
