Cov khoom ntiag tug ntawm txhuas pcb | YMS

Yongmingsheng technology aluminium pcb cov tuam txhab coj koj kom nkag siab kev ua haujlwm ntawm txhuas pcb.

Txhuas pcb, ib hom ntawm cov khoom siv, yog ib hom hlau pcb tooj liab clad phaj nrog zoo kub ua kom tsis muaj nuj nqi.Nws yog daim ntawv cov khoom ua los ntawm cov ntaub ua hluav taws xob fiberglass daim ntaub lossis lwm cov ntaub ntawv pov tseg hauv cov kab, ib qho cob thiab lwm txheej insulating nplaum txheej, ib lossis ob tog npog nrog cov ntawv ci tooj liab thiab tsim los ntawm kub nias. Nws yog hu ua tooj liab clad ntawv ci laminated txhuas pcb, hu ua txhuas raws tooj liab clad phaj.

Cov khoom ntawm txhuas pcb

1.Txhais tshav kub dissipation kev ua tau zoo

Aluminium puag tooj liab clad ntawv ci muaj qhov kub zoo ua kom tsis muaj zog, uas yog qhov tshwj xeeb tshaj plaws cov yam ntxwv ntawm hom phaj no.Qhov PCB ua nrog nws tsis tsuas tuaj yeem tiv thaiv kev ua haujlwm kub ntawm cov khoom thiab pcb thauj ntawm nws los ntawm qhov nce, tab sis kuj ceev nrooj emit lub tshav kub uas tsim los ntawm lub zog txuas ntxiv, cov hluav taws xob loj thiab cov hluav taws xob sib txuas loj.

Tsis tas li ntawd, vim tias nws qhov tsawg tsawg, lub teeb ceeb thawj (2.7g / cm³), tiv thaiv los tiv thaiv oxidation, tus nqi yog pheej yig dua, yog li nws tau dhau los ua cov hlau siv ntau tshaj plaws tooj liab cladding phaj, tus nqi ntawm cov phaj sib xyaw.Insulated aluminium pcb saturated thermal resistance yog 1.10 ℃ / W, thermal tsis kam yog 2.8 ℃ / W, uas zoo heev txhim kho tooj liab hlau fuse tam sim no.

2.Txhais kev ua haujlwm zoo thiab ua tau zoo ntawm lub tshuab

Aluminium puag tooj liab clad phaj muaj lub zog loj thiab lub zog tawv, uas yog qhov zoo tshaj qhov txhav ntawm hom tooj liab clad phaj thiab ceramic pcb.Nws tuaj yeem paub qhov chaw ua khoom ntawm thaj chaw loj ntawm cov luam tawm ntawm cov hlau pcb, tshwj xeeb tshaj yog haum rau mount hnyav hnyav ntawm pcb zoo li no.

Tsis tas li ntawd, txhuas pcb kuj muaj qhov zoo flatness.Nws tuaj yeem siv rau kev rauj, riveting thiab lwm yam kev sib dhos ua haujlwm ntawm lub pcb lossis khoov thiab sib ntswg raws qhov tsis txuas ntawm cov PCB ua los ntawm nws.Tab sis cov tshuaj zoo li hom tooj liab- clad phaj tsis tau.

3.High dimensional stability

Thermal expansion (dimensional stability) yog ib qho teeb meem rau txhua yam ntawm tooj liab clad daim hlau, tshwj xeeb tshaj yog cov thermal nthuav nyob rau hauv cov tuab kev taw qhia ntawm cov phaj (Z txoj kab), uas cuam tshuam rau qhov zoo ntawm metallization qhov thiab lub voj voog.Qhov laj thawj tseem ceeb yog tias txoj kab nthuav dav coefficient ntawm lub phaj yog txawv, xws li tooj liab, thiab linear expansion coefficient ntawm epoxy iav fiber ntau daim ntaub pcb yog 3.

Kev tawm ncaj ncaj sib txawv ntawm ob yog loj heev, uas tuaj yeem yooj yim ua rau qhov sib txawv ntawm qhov thermal nthuav ntawm lub pcb, uas ua rau lub pob tawg lossis rhuav tshem cov xaim tooj liab thiab kab hlau qhov.Qhov linear expansion coefficient ntawm aluminium pcb yog nruab nrab ntawm, nws yog me dua li ntawm cov kab hluav taws xob dav dav pcb.Yog li ntawd, nws tau los ze dua rau cov kab hluav taws xob nthuav dav ntawm cov tooj liab, uas tau txais txiaj ntsig los xyuas kom zoo thiab muaj kev ntseeg siab ntawm cov ntawv luam tawm.

Yog li ntawd qhov kev ua tau zoo ntawm aluminium pcb.Yongmingsheng yog tus kws tshaj lij kev lag luam ntawm aluminium pcb.Hope cov ntawv no yuav tsum koj pab, zoo siab tos txais txhua tus neeg sab laj.
