Usoro nrụpụta Aluminom PCB

Aluminom PCB Nrụpụta Usoro Usoro mmepụta nke aluminom PCB na OSP elu imecha: Ịcha → Drilling → Circuit → Acid / alkaline etching → Solder Mask → Silkscreen → V-cut → PCB Test → OSP → FQC → FQA → mbukota → Nbupu.

Usoro mmepụta nke aluminom PCB na HASL n'elu imecha: Ịcha → Drilling → Circuit → Acid / alkaline etching → Solder Mask → Silkscreen → HASL → V-cut → PCB Test → FQC → FQA → mbukota → Nbupu .

YMSPCB nwere ike inye PCB isi aluminom na otu usoro imecha elu dị ka FR-4 PCB: Immersion Gold / thin / silver, OSP, wdg.

N'ime usoro aluminom PCB, a na-agbakwunye akwa dielectric dị mkpa n'etiti oyi akwa sekit na oyi akwa. Nke a oyi akwa nke dielectric bụ ma eletriki mkpuchi, yana thermally conductive. Mgbe agbakwunyere oyi akwa dielectric, oyi akwa sekit ma ọ bụ foil ọla kọpa na-etched
