引發TVS短路的典型(xing)的原因是管芯與(yu)內引線組件、底座銅片(pian)燒結不良，在燒結界(jie)面(mian)出現大(da)面(mian)積(ji)空(kong)洞，空(kong)洞可能是由于焊(han)料(liao)不均勻或粘結界(jie)面(mian)各層(ceng)(ceng)材(cai)料(liao)玷污、氧化使(shi)(shi)焊(han)料(liao)沾潤(run)不良，造成燒焊(han)時(shi)焊(han)料(liao)與(yu)芯片(pian)或金屬電(dian)極沒(mei)有良好的熔(rong)合焊(han)接引起(qi)的。空(kong)洞面(mian)積(ji)較大(da)時(shi)，電(dian)流(liu)在燒結點(dian)附近(jin)匯(hui)聚，管芯散熱(re)(re)(re)困(kun)難(nan)，造成熱(re)(re)(re)電(dian)應力(li)集中，產生(sheng)局(ju)部(bu)熱(re)(re)(re)點(dian)，嚴重(zhong)時(shi)引起(qi)熱(re)(re)(re)奔，使(shi)(shi)器(qi)(qi)件燒毀(hui)(hui)(hui)。對這些燒毀(hui)(hui)(hui)的器(qi)(qi)件。進行解剖分析(xi)，可以看到有芯片(pian)局(ju)部(bu)較深的熔(rong)融(rong):空(kong)洞面(mian)積(ji)較小(xiao)時(shi)，可加速焊(han)料(liao)熱(re)(re)(re)疲勞(lao)，使(shi)(shi)焊(han)料(liao)層(ceng)(ceng)會(hui)產生(sheng)疲勞(lao)龜裂，引起(qi)器(qi)(qi)件熱(re)(re)(re)阻增(zeng)大(da)，終導致器(qi)(qi)件。過熱(re)(re)(re)燒毀(hui)(hui)(hui)。
