Dhizaini Yekufunga kweMetal Core PCBs (MCPCBs)

Kuita uye kuvimbika kweMetal Core PCBs kunotsamira pakunyatso funga nezve akati wandei magadzirirwo zvinhu:

Kuwedzera Kwekupisa

Iyo coefficient of thermal expansion (CTE) inomiririra dhigirii iro chinhu chinowedzera kana zvibvumirano mukupindura shanduko yekushisa. MuMCPCBs, maCTE asina kufananidzwa pakati pesimbi musimboti uye mamwe maseru anogona kutungamira kune zvimiro nyaya:

• Kusarudzwa Kwezvinhu: sarudza zvinhu nemaCTE anoenderana kuderedza kushushikana pakati pezvikamu panguva yekupisa bhasikoro.
• CTE Management: Shandisai nzira dzekuyamura dzinopisa uye gadzirisa makunakuna kuti muderedze kushushikana.
• Lamination process: Gadzirisa iyo lamination process yekubatanidza ma layer zvakasimba, kudzivirira delamination.

Kuchengetedza Kwemhepo

Basa rekutanga reMCPCB nderekubvisa kupisa zvakanaka, nekudaro:

• Core Zvinyorwa: Sarudza simbi dzakaita sealuminium kana mhangura kune yavo yakakwirira yekupisa conductivity.
• Insulating Layer: Shandisa dielectric zvinhu zvine high thermal conductivity kubhuroka simbi musimboti uye maseketi masekete.
