PCB ( E Bipụtara Circuit Board ), a makwaara dị ka e biri ebi circuit osisi, bụ ihe dị mkpa electronic akụrụngwa, a nkwado maka electronic mmiri, na a ụgbọelu maka eletriki njikọ nke latrik. N'ihi na e mere ya site electronic-ebi akwụkwọ, ọ na-akpọ a "na-ebi akwụkwọ" circuit osisi.

Function

Mgbe kọmputa akụrụngwa adopts ndị e biri ebi osisi, n'ihi na-anọgidesi nke otu biri ebi osisi, akwụkwọ ntuziaka wiring na-ezere, na latrik nwere ike na-akpaghị aka na-etinyere ma ọ bụ ndokwasa, na-akpaghị aka soldered, na-akpaghị aka na-ahụrụ iji hụ na àgwà nke kọmputa akụrụngwa . Dịkwuo ọrụ arụpụtaghị, belata-akwụ ụgwọ, na ikwado mmezi.

Development

E biri ebi mbadamba nwere, ghọrọ usoro si otu n'ígwé na abụọ-kwadoro, multi-oyi akwa na mgbanwe, ma ka na ịnọgide na-enwe ha na nwoke na ọnọdụ. N'ihi na-aga n'ihu mmepe nke elu kpọmkwem, elu njupụta na elu pụrụ ịdabere, olu na-ebelata, na-eri na-ebelata, na arụmọrụ na-akakwa mma, nke mere na e biri ebi osisi ka na-ekwusi ike na vitality na mmepe nke kọmputa akụrụngwa na-eme n'ọdịnihu .

nhazi ọkwa

Dị ka ọnụ ọgụgụ nke n'ígwé, na sekit osisi na-ekewa atọ isi ige: otu panel, abụọ panel, na multi-oyi akwa circuit osisi.

Nke mbụ bụ otu panel. On ihe ndị kasị mkpa PCB, akụkụ na-lekwasị na otu akụkụ na wires na-lekwasị dị n'akụkụ nke ọzọ. N'ihi na waya naanị na-egosi na otu akụkụ, ọ na-akpọ otu-kwadoro circuit osisi.

Single ogwe ndị na-emekarị mfe ime na ala na-eri, ma mwepu bụ na ha nwere ike ọ bụghị etinyere na ngwaahịa na na kwa mgbagwoju anya.

The abụọ panel bụ ndọtị nke otu panel. Mgbe otu oyi akwa wiring ike izute mkpa nke na kọmputa na ngwaahịa, na abụọ panel na-eji.

N'akụkụ abụọ a ga ọla kọpa-clad metụtara, na vias ike ga-eji na-atụgharị na edoghi n'etiti abụọ n'ígwé na-etolite chọrọ netwọk njikọ.

A multi-oyi akwa osisi na-ezo aka a biri ebi osisi na-enwe atọ ma ọ bụ karịa n'ígwé nke a conductive ụkpụrụ oyi akwa na-egbochi ihe onwunwe interposed therebetween, na conductive nakawa etu esi therebetween na-interconnected ka chọrọ.

Multi-oyi akwa sekit mbadamba bụ ngwaahịa nke mmepe nke electronic ọmụma technology na ntụziaka nke elu na-agba, multi-ọrụ, nnukwu ike, obere olu, thinning na ìhè arọ.

Dị ka e ji mara, na sekit osisi na-ekewa a adụ osisi (FPC), a ike osisi (PCB), na a nro na ike osisi (FPCB).
