What causes terminal plating to degrade over time?<\/strong><\/h3>\n<p class=\"\" data-start=\"5136\" data-end=\"5305\">Plating degradation is primarily caused by <strong data-start=\"5179\" data-end=\"5192\">oxidation<\/strong>, <strong data-start=\"5194\" data-end=\"5216\">fretting corrosion<\/strong>, \u0438 <strong data-start=\"5222\" data-end=\"5241\">mechanical wear<\/strong>, especially under high humidity, vibration, or thermal cycling.<\/p>\n<hr class=\"\" data-start=\"5307\" data-end=\"5310\" \/>\n<h3 class=\"\" data-start=\"5312\" data-end=\"5379\"><strong data-start=\"5316\" data-end=\"5379\">2. Why is contact resistance important in connector design?<\/strong><\/h3>\n<p class=\"\" data-start=\"5380\" data-end=\"5552\">Rising contact resistance leads to <strong data-start=\"5415\" data-end=\"5432\">\u041d\u0430\u0433\u0440\u0435\u0432 \u0432 \u0434\u0436\u043e\u0443\u043b\u044f\u0445<\/strong>, which reduces current capacity, causes energy loss, and can ultimately lead to terminal failure or electrical hazards.<\/p>\n<hr class=\"\" data-start=\"5554\" data-end=\"5557\" \/>\n<h3 class=\"\" data-start=\"5559\" data-end=\"5642\"><strong data-start=\"5563\" data-end=\"5642\">3. Which plating layer is best for frequent connections and disconnections?<\/strong><\/h3>\n<p class=\"\" data-start=\"5643\" data-end=\"5790\"><strong data-start=\"5643\" data-end=\"5659\">Gold plating<\/strong> is ideal for high mating cycles due to its excellent corrosion resistance, low insertion force, and minimal degradation over time.<\/p>\n<hr class=\"\" data-start=\"5792\" data-end=\"5795\" \/>\n<h3 class=\"\" data-start=\"5797\" data-end=\"5888\"><strong data-start=\"5801\" data-end=\"5888\">4.

Tin requires <strong data-start=\"5925\" data-end=\"5946\">high normal force<\/strong>, and in environments prone to vibration or high current, it is more vulnerable to wear and corrosion. Proper <strong data-start=\"6056\" data-end=\"6076\">design tolerance<\/strong> is essential.<\/p>\n<hr class=\"\" data-start=\"6092\" data-end=\"6095\" \/>\n<h3 class=\"\" data-start=\"6097\" data-end=\"6157\"><strong data-start=\"6101\" data-end=\"6157\">5.

For example, <strong data-start=\"6279\" data-end=\"6289\">silver<\/strong> may form sulfide films in polluted air, while <strong data-start=\"6336\" data-end=\"6346\">nickel<\/strong> offers good hardness but poor conductivity.<\/p>\n<hr class=\"\" data-start=\"6392\" data-end=\"6395\" \/>\n<h3 class=\"\" data-start=\"6397\" data-end=\"6470\"><strong data-start=\"6401\" data-end=\"6470\">6.
