Kedu ihe bụ Multi Layers MCPCB?
Ogwe Metal Core Printed Circuit Board (MPCB) , makwaara dị ka PCB thermal ma ọ bụ metal kwadoro PCB, bụ ụdị PCB nke nwere ihe ígwè dị ka isi ya maka akụkụ nke okpomọkụ na-agbasa. Igwe dị arọ (ihe fọrọ nke nta ka ọ bụrụ aluminom ma ọ bụ ọla kọpa) na-ekpuchi akụkụ 1 nke PCB. Metal isi nwere ike na-ezo aka na metal, ịbụ ma n'etiti ebe ma ọ bụ na azụ nke osisi. Ebumnuche nke isi nke MCPCB bụ ibugharị okpomọkụ pụọ na akụkụ bọọdụ dị oke mkpa yana mpaghara ndị na-adịchaghị mkpa dị ka nkwado heatsink metal ma ọ bụ isi ọla. A na-eji ọla ndị dị na MCPCB eme ihe dị ka ihe ọzọ na bọọdụ FR4 ma ọ bụ CEM3.
Bọọdụ sekit sekit e biri ebi (MPCCB) nke a makwaara dị ka PCB thermal, na-etinye ihe igwe dị ka ntọala ya na-emegide FR4 ọdịnala, maka iberi mgbasa ọkụ nke osisi. Okpomọkụ na-ewuli elu n'ihi ụfọdụ ihe eletrọnịkị n'oge arụ ọrụ nke osisi. Ebumnuche nke igwe ahụ bụ ka a tụpụ okpomọkụ a pụọ na akụkụ bọọdụ dị oke mkpa yana gaa n'akụkụ ndị na-adịchaghị mkpa dị ka nkwado heatsink metal ma ọ bụ isi ọla. N'ihi ya, PCB ndị a dabara adaba maka njikwa okpomọkụ.
Na multilayer MCPCB, a ga-ekesa akwa akwa n'akụkụ nke ọ bụla nke isi igwe. Dịka ọmụmaatụ, na bọọdụ 12-layer, isi ígwè ahụ ga-adị n'etiti ya na akwa 6 n'elu na 6 n'ime ala.
