Part One: Gịnị bụ Aluminom PCB?
Ngwakọta aluminom bụ ụdị bọọdụ ejiri ọla kọpa kpuchie ọla nwere ọmarịcha ọrụ mkpofu ọkụ.N'ozuzu, bọọdụ nwere otu akụkụ nwere akwa atọ: oyi akwa sekit (ọla kọpa), oyi akwa mkpuchi, na oyi akwa metal.Maka ngwa ngwa dị elu, e nwekwara atụmatụ nwere akụkụ abụọ nwere nhazi nke oyi akwa sekit, mkpuchi mkpuchi, ntọala aluminum, mkpuchi mkpuchi, na oyi akwa sekit.Ọnụ ọgụgụ dị nta nke ngwa na-agụnye bọọdụ multi-layer, nke enwere ike ịmepụta site na ijikọ bọọdụ multi-layer nkịtị na mkpuchi mkpuchi na ntọala aluminum.
Mkpụrụ aluminom nwere otu akụkụ: Ọ nwere otu oyi akwa nke ihe na-eme ihe nlegharị anya, ihe mkpuchi, na efere aluminom (mkpụrụ osisi).
Mkpụrụ aluminom nwere akụkụ abụọ: Ọ na-agụnye ọkwa abụọ nke ihe na-eduzi ihe n'ígwé, ihe mkpuchi, na efere aluminom (substrate) jikọtara ọnụ.
Multi-Layer printed aluminum circuit board: Ọ bụ bọọdụ sekit e biri ebi nke emere site na laminating na bonding atọ ma ọ bụ karịa n'ígwé nke conductive ụkpụrụ n'ígwé, insulating ihe, na aluminum efere (mkpụrụ) ọnụ.
Kewara site na usoro ọgwụgwọ elu:
mbadamba ọla edo (Chemical thin gold, Chemical thick gold, Selective gold plating)
Akụkụ nke abụọ: Ụkpụrụ na-arụ ọrụ nke aluminom
A na-agbanye ngwaọrụ ike n'elu oyi akwa sekit.A na-eduzi okpomọkụ nke ngwaọrụ ndị a na-eme n'oge a na-arụ ọrụ ngwa ngwa site na mkpuchi mkpuchi na oyi akwa metal, nke ahụ na-ekpochapụ okpomọkụ ahụ, na-enweta ọkụ ọkụ maka ngwaọrụ.
E jiri ya tụnyere FR-4 ọdịnala, ihe ndị aluminom nwere ike ibelata nguzogide okpomọkụ, na-eme ka ha bụrụ ndị na-eduzi okpomọkụ.E jiri ya tụnyere seramiiki seramiiki nwere nnukwu ihe nkiri, ha nwekwara ihe arụrụ arụ dị elu.
Ọzọkwa, aluminom substrates nwere uru ndị a pụrụ iche:
- Nrube isi na ihe RoH chọrọ
- Mma mgbanwe na usoro SMT
- Ijikwa mgbasa ọkụ nke ọma na imewe sekit iji belata ọnọdụ okpomọkụ na-arụ ọrụ modul, ịgbatị ogologo ndụ, kwalite njupụta ike na ntụkwasị obi.
- Mbelata na mgbakọ nke ikpo ọkụ na ngwaike ndị ọzọ, gụnyere ihe ndị na-ahụ maka ikpo ọkụ, na-ebute obere ngwaahịa ngwaahịa na obere ngwaike na ọnụ ahịa mgbakọ, yana ngwakọta kacha mma nke sekit ike na njikwa.
- Ndochi nke seramiiki na-esighi ike maka ịdịte aka n'arụ ọrụ ka mma
Nkebi nke atọ: Ngwakọta ihe nke aluminom
1. Circuit Layer
A na-edobe oyi akwa sekit (nke a na-ejikarị ọla kọpa electrolytic) iji mepụta sekit ndị e biri ebi, nke a na-eji maka mgbakọ akụrụngwa na njikọ.Tụnyere FR-4 ọdịnala, nke nwere otu ọkpụrụkpụ na obosara ahịrị, ihe ndị aluminom nwere ike ibu iyi dị elu.
2. mkpuchi mkpuchi
Igwe mkpuchi mkpuchi bụ teknụzụ bụ isi na ihe aluminom, na-eje ozi na mbụ maka adhesion, mkpuchi, na njikwa okpomọkụ.Ngwunye mkpuchi nke ihe aluminom bụ ihe mgbochi ọkụ kacha pụta ìhè n'ụdị modul ike.Nrụpụta ọkụ dị mma nke oyi akwa mkpuchi na-eme ka mgbasa nke okpomọkụ na-emepụta n'oge arụ ọrụ ngwaọrụ, na-eduga n'ibelata okpomọkụ na-arụ ọrụ, ịba ụba ike modul, mbelata nha, ogologo ndụ ogologo, na mmepụta ike dị elu.
3. Metal Base Layer
Nhọrọ nke igwe maka ntọala igwe mkpuchi na-adabere na nleba anya zuru oke nke ihe ndị dị ka ọnụọgụ nke mgbaba ọkụ, okpomọkụ, ike, ike, ịdị arọ, ọnọdụ elu, na ọnụ ahịa.
Nkebi nke anọ: Ihe kpatara ị na-ahọrọ ihe ndị aluminom
1. Mgbasa ọkụ
Ọtụtụ bọọdụ dị n'akụkụ abụọ na nke multi-layer nwere nnukwu njupụta na ike, na-eme ka ikpo ọkụ ọkụ na-ama aka.Ngwa ihe eji eme ihe dị ka FR4 na CEM3 bụ ndị na-eduzi okpomọkụ na-adịghị mma ma nwee mkpuchi n'etiti oyi akwa, na-eduga na nkwụsị ọkụ na-ezughị ezu.Aluminom substrates na-edozi okwu ikposa ọkụ a.
2. Mgbasawanye okpomọkụ
