Кроме того, существует технология термоэлектрического разделения PCB на основе меди (также известная как технология прямого касания). Это означает, что толщина меди в нужном месте увеличивается с помощью отверстия для покрытия сварочным материалом и гальванической меди, а тепло передается непосредственно от светодиода или других компонентов к медной базе, в то время как сеть цепей независима от тепловой сети.

Как производитель MCPCB, Hitech Circuits производит различные ПХБ на основе меди для своих клиентов.

Для мощных светодиодных ламп (1000 Вт +) и источников питания.

В области светодиодов существует 4 типа платы на основе меди.

[hitechpcb]

Как правило, PCB на основе меди имеет ту же структуру, что и PCB на основе алюминия - однослойная, двухслойная панельная монтажная поверхность, двухслойная двухэлементная монтажная поверхность и четырехслойная двухэлементная монтажная поверхность. Даже если они используют тот же предварительно пропитанный материал для изоляции медного слоя. Однако медная подложка (398W / mK) обладает лучшей теплопроводностью, чем алюминиевая (237W / mK).
