PCB aluminum mkpụrụ nwere ọtụtụ aha, aluminum cladding, aluminum PCB, metal clad biri ebi Circuit osisi (MPCB), thermally conductive PCB, wdg The uru nke PCB aluminum mkpụrụ bụ na okpomọkụ dissipation bụ budata mma karịa ọkọlọtọ FR-4 Ọdịdị. na dielectric eji na-emekarị Ọ bụ 5 ka 10 ugboro thermal conductivity nke ot epoxy iko, na okpomọkụ nyefe index nke otu ụzọ n'ụzọ iri nke ọkpụrụkpụ bụ nke ọma karịa omenala isiike PCB. Ka anyị ghọta ụdị PCB aluminum substrates n'okpuru.
1. Mgbanwe aluminom substrate
Otu n'ime ihe ọhụrụ kachasị ọhụrụ na ihe IMS bụ dielectrics na-agbanwe agbanwe. Ihe ndị a nwere ike inye ihe mkpuchi ọkụ eletrik dị mma, mgbanwe na conductivity thermal. Mgbe etinyere ya na ihe ndị aluminom na-agbanwe agbanwe dị ka 5754 ma ọ bụ ihe ndị yiri ya, enwere ike ịmepụta ngwaahịa iji nweta ụdị dị iche iche na akụkụ dị iche iche, nke nwere ike iwepụ ngwaọrụ ndị na-edozi ọnụ ahịa, eriri na njikọ njikọ. Ọ bụ ezie na ihe ndị a na-agbanwe agbanwe, a haziri ha ka ha na-ehulata ebe ma nọgide na-adị.
2. Ngwakọta aluminom ngwakọta aluminom
N'ime usoro "ngwakọ" IMS, a na-ahazi "sub-components" nke ihe ndị na-abụghị thermal, na Amitron Hybrid IMS PCBs na-ejikọta ya na aluminom substrate na ihe ọkụ. Ihe a na-ahụkarị bụ 2-layer ma ọ bụ 4-layer subassembly nke omenala FR-4, nke nwere ike jikọta ya na ihe ntanetị aluminom na thermoelectric iji nyere aka wepụ okpomọkụ, mụbaa isi ike, ma rụọ ọrụ dị ka ọta. Uru ndị ọzọ gụnyere:
1. Ọnụ ala karịa ihe niile na-eduzi thermal.
2. Nye arụmọrụ okpomọkụ ka mma karịa ngwaahịa FR-4 ọkọlọtọ.
3. Enwere ike ikpochapụ ikpo ọkụ ọkụ dị oke ọnụ na usoro mgbakọ metụtara ya.
4. Enwere ike iji ya na ngwa RF nke chọrọ njirimara ọnwụ RF nke oyi akwa PTFE.
5. Jiri akụrụngwa windo na aluminom nabata site-oghere components, nke na-enye ohere njikọ na cables gafere njikọ site na mkpụrụ mgbe ịgbado ọkụ gburugburu nkuku ike a akara na-enweghị mkpa pụrụ iche gaskets ma ọ bụ ndị ọzọ dị oké ọnụ nkwụnye.
Atọ, multilayer aluminum substrate
N'ahịa ọkụ na-arụ ọrụ dị elu, multilayer IMS PCB bụ nke multilayer thermally conductive dielectrics. Ihe owuwu ndị a nwere otu sekit ma ọ bụ karịa nke e liri na dielectric, a na-ejikwa vias kpuru ìsì dị ka ụzọ ọkụ ọkụ ma ọ bụ ụzọ mgbaama. Ọ bụ ezie na atụmatụ nke otu oyi akwa dị oke ọnụ ma na-arụ ọrụ nke ọma iji nyefee okpomọkụ, ha na-enye ngwọta dị nro dị mfe ma dị irè maka atụmatụ mgbagwoju anya.
Anọ, site na oghere aluminum mkpụrụ
N'ime usoro kachasị mgbagwoju anya, oyi akwa nke aluminom nwere ike ịmepụta "isi" nke usoro okpomọkụ nke multilayer. Tupu lamination, aluminum na-electroplated na jupụta dielectric n'ọdịnihu. Enwere ike ịtinye ihe ọkụ ma ọ bụ ihe ndị dị n'okpuru ala n'akụkụ abụọ nke aluminom site na iji ihe ntanye ọkụ. Ozugbo laminated, nzuko okokụre yiri a omenala multilayer aluminum mkpụrụ site mkpọpu ala. Edebere site na oghere na-agafe oghere na aluminom iji nọgide na-enwe mkpuchi ọkụ. N'aka nke ọzọ, isi ọla kọpa nwere ike ikwe ka njikọ eletrik kwụ ọtọ na mkpuchi vias.
