基于硕凯ESD的蓝牙耳机静电整改案例分析
本文为蓝牙耳机静电整改案例分析。
一、描述
1.供电:锂电池供电。
2.USB外壳与工作地直连。
3.静电测试等级:
①音乐模式测试:接触±4KV/10次,空气±8KV/10ddd次;接触打产品USB外壳,空气打控制盒缝隙、按键缝隙、麦克风孔、喇叭壳缝隙、喇叭调音孔、喇叭出音孔。
② 充电模式测试:接触±4KV/10次,空气±8KV/10次;接触打产品USB外壳,空气打控制盒缝隙、按键缝隙、麦克风孔、喇叭壳缝隙、喇叭调音孔、喇叭出音孔。
4.产品整机图:
图三
客户产品原设计PCB工作地与外壳不相连,对外壳打接触放电时U1 IC损坏。
二、测试结果
1.音乐模式:对产品USB外壳测试接触放电±6KV/10次,测试OK。对产品控制盒缝隙、按键缝隙、麦克风孔、喇叭壳缝隙、喇叭调音孔、喇叭出音孔测试空气放电±12KV/10次,测试OK。
2.充电模式:对产品USB外壳测试接触放电±4KV/10次,测试OK。对产品控制盒缝隙、按键缝隙、麦克风孔、喇叭壳缝隙、喇叭调音孔、喇叭出音孔测试空气放电±8KV/10次,测试NG。
反复测试最终发现是测试喇叭缝隙和喇叭调音孔处会导致声音发生变化,严重的喇叭直接没有声音。
三、分析
1.静电从喇叭两条信号线直接传导到IC,导致IC内部部分损坏。
2.静电耦合到喇叭两条信号线,再传导到IC,导致IC内部部分损坏。
四、整改思路
1.将喇叭外壳缝隙、调音孔用绝缘胶布封住,测试空气放电±8KV/10次,测试通过。证明静电不是耦合进去,而是传导进去。由于结构和PCB不能修改只能从增加器件入手。
2.将喇叭信号线上对地电容(10nF)换成200nF,测试空气放电±8KV/10次,测试通过。客户回去测试音频参数,参数超标,经试验音频对地电容最大只能用22nF。
3.将喇叭信号线上对地电容换成22nF,测试空气放电±8KV/10次,测试NG。
4.在四根喇叭信号线上并SC0402E100M05,测试空气放电±8KV/10次,测试NG。
5.在四根喇叭信号线上并SC0603ML120M、SE05N2S01GA、SE05N2S01HZ,测试空气放电±8KV/10次,均可通过。提高等级测试空气放电±12KV/10次,均可通过。
6.客户为节约成本每个喇叭只用一颗ESD,测试空气放电±8KV/10次,测试NG。
7.客户为节约成本去掉信号线对地电容,去掉信号线的磁珠,四根信号线对地并上ESD,测试空气放电±8KV/10次,测试通过。提升测试等级测试空气放电±10KV/10次,测试通过。测试空气放电±11KV/10次,NG。
由于客户PCB板预留的是0201封装,所以ESD只能使用0201封装的器件。
五、解决方法
1.喇叭四根信号线对地加SE05N2S01HZ。
2.喇叭四根信号线对地电容去掉。
3.喇叭四根信号线串的磁珠去掉。
六、总结
1.音频信号最大只能使用22nF的对地电容。
2.大容值电容对静电有很好的吸收效果。
3.容值越大的ESD吸收静电效果越好。

【经验】ESD常见应用选型的经验分享
本文主要介绍硕凯电子两款ESD器件(PE0402N05G01B,PE0402S05G01R)应用选型的经验。一般来说,主要是根据被保护线路的信号传输速率来考虑,速率越高,需要选择Cp越小的ESD保护器件。反之,传输速率越低,需要选择Cp适当大一点的ESD保护器件。

【应用】TWS蓝牙耳机天线、电池端充放电的ESD保护方案
本文介绍关于TWS蓝牙耳机的ESD静电的防护问题。针对蓝牙天线的ESD防护,推荐高特GESD0301BU、GESD0501BU ESD保护组件,的寄生电容只有0.2pF,适用于天线的ESD防护,确保信号快速通过,防护静电干扰减少延迟损耗;针对电池端的充放电保护推荐GESD8D5V0、GESD5Z5V0,有效防护充放电时造成的瞬间电流冲击,还能防护在拿取耳机时因为人体静电造成的伤害。
