Ir labi zin\u0101ms, ka mitrums boj\u0101 elektronisk\u0101s sast\u0101vda\u013cas. Viens no galvenajiem veidiem, k\u0101 mitrums samazina elektrisko izpildmeh\u0101nismu kalpo\u0161anas laiku, ir jonu migr\u0101cijas \u012bssl\u0113gumi<\/strong>.<\/p>

1. Kas ir jonu migr\u0101cijas \u012bssl\u0113gums?<\/strong><\/h2>

<\/p>

Jonu migr\u0101cija notiek, kad mitrums un pies\u0101r\u0146ot\u0101ji<\/strong> uz sh\u0113mas plates veicina jonu p\u0101rvieto\u0161anos starp vad\u012bt\u0101jiem, izraisot \u012bssl\u0113gumus. Process notiek \u0161\u0101di:<\/p>

1\ufe0f\u20e3 Elektrisk\u0101 lauka kl\u0101tb\u016btne<\/strong> starp diviem vad\u012bt\u0101jiem uz izolatora.
2\ufe0f\u20e3 Elektrol\u012btisk\u0101 reakcija<\/strong> notiek pie anoda, atbr\u012bvojot met\u0101la jonus.
3\ufe0f\u20e3 Joni migr\u0113<\/strong> elektrisk\u0101 lauka ietekm\u0113 katoda virzien\u0101.
4\ufe0f\u20e3 Kad katod\u0101 ir uzkr\u0101jies pietiekami daudz jonu, vado\u0161as tilta formas<\/strong>, izraisot \u012bssavienojumu.<\/p>

Tas noved pie izpildmeh\u0101nisma PCBA (iespiedsh\u0113mas plates komplekta) k\u013c\u016bme<\/strong>.<\/p>

2. Bie\u017e\u0101kie jonu migr\u0101cijas c\u0113lo\u0146i uz PCBA<\/strong><\/h2>

Jonu migr\u0101cijas \u012bssl\u0113gumi parasti rodas \u0161\u0101dos apst\u0101k\u013cos:<\/p>
