No uso do chip MLCC, muitos clientes encontrarão rachaduras no capacitor, curto-circuito, queima e outros fenômenos, então como lidar com esses fenômenos?
Em primeiro lugar, precisamos conhecer as causas desses fenômenos.
A. Rachadura (refere-se à rachadura no capacitor que faz com que o produto não funcione normalmente). Este fenômeno geralmente é causado por baixa resistência.
As razões são as seguintes.
1. PCB é principalmente circuito aberto após força externa.
2. Se o corpo sem capacitor for impactado por força externa, pode haver curto-circuito ou baixa resistência.
3. Tensão de estresse aplicada muito alta levará à falha do capacitor MLCC, geralmente curto-circuito ou baixa resistência, mas este tipo de fenômeno não deve ser muito no caso de tolerância suficiente.
Neste caso, geralmente é necessário verificar se o produto será vibrado ou sacudido durante o trabalho e, em seguida, verificar se a capacidade do produto atende aos requisitos.
B. Curto-circuito queimado (refere-se ao dano do capacitor na placa PCB, resultando na falha do produto para continuar a funcionar).
As razões para este fenômeno são as seguintes.
1. O modelo do pacote do capacitor não é grande o suficiente;
2. Subsídio reservado insuficiente;
3. A resistência à tensão é muito baixa ou a corrente do produto é muito alta.
Se isso acontecer, precisamos substituir o modelo do capacitor do chip e verificar o motivo específico. Em seguida, opte por substituir a capacidade ou modelo do capacitor do chip.
Se você não conseguir encontrar um modelo adequado para substituir, você pode usar os capacitores em paralelo ou em série para resolver o problema.
A Kingtronics pode oferecer suporte com chip MLCC qualificado.
