Kev ua tau zoo ntawm Aluminium puag PCB
Jun 08, 2018

Aluminium puag hauv PCB yog cov khoom siv txhuam hauv cov ntoo, ua los ntawm cov tooj ci, thermal thaiv txheej thiab hlau substrate muaj pes tsawg leeg, peb tau saib zoo li cas cov khoom ntawm Aluminium PCB.

散热 性

Kub dissipation

Cov teeb meem loj, Multipurpose lub teeb, Kev sib txuas lus, Lub koob yees duab, Kev sib txuas lus, Kev sib txuas lus, Kev sib txuas lus, Kev sib txuas lus, Xov tooj cua, Chaw ua hauj lwm hauv Internet Tsis muaj peev xwm, Tsis siv cov teeb meem kev sib txuas lus, Txawm li cas los xij tau daws qhov teeb meem no.

Tam sim no, lub cua kub dissipation ntawm ntau ob sab sab PCB, multilayer sab PCB, siab ceev thiab siab PCB nyuaj. Cov ntawv cog lus ntawm Circuit Court xws li FR4, CEM3 yog ib tug neeg ua haujlwm tsis zoo ntawm cov cua sov, kev sib tsuam hluav taws xob, cua sov tsis tawm. Cov khoom siv hluav taws xob hauv zos tsis cais tawm, ua rau kub tsis ua hauj lwm ntawm cov khoom hluav taws xob, thiab cov txhuas txheej txheem yuav daws tau qhov teeb meem kub thoob.

Thermal expansion

热胀冷缩 是 物质 的 共同 本性, Txhawb Nqa Cov Thawj Coj Txhawb Nqa Cov Tuam Tsev Txhawb Nqa Cov Thawj Coj Li Ua Xwb, Txawm li cas los xij, Kev Tiv Thaiv thiab Chaw Ua Haujlwm Cov neeg ua hauj lwm thiab kev sib koom tes yog ib qho teeb meem SMT (los ntawm kev sib koom ua ke) 热胀冷缩 问题.

Expansion thiab contraction yog ib yam khoom siv, ntau cov ntaub ntawv coefficient ntawm thermal expansion txawv. Aluminium hauv paus PC B tau zoo los daws qhov teeb meem ntawm cov tshav kub, yog li ntawd cov pawg thawj coj ntawm cov khoom sib txawv los daws qhov teeb meem ntawm kev thermal expansion thiab contraction, ua kom muaj kev ruaj siab thiab kev ntseeg tau ntawm tag nrho cov tshuab thiab cov cuab yeej hluav taws xob. Qhov tshwj xeeb tshaj yog kev daws ntawm SMT (deg mount technology) teeb meem ntawm thermal expansion thiab contraction.

Dimensional stability

Cov khoom lag luam, Tshaj tawm hauv lub teeb meem, txhua lub sijhawm ntawm 30 - 150 ℃, nyias muaj nyias 2.5 ~ 3.0%.

thaj ntawm qhov kev dimensional stability ntawm lub tshuab PC3 qij yog qhov ruaj khov ntau tshaj li cov khoom siv ntawm PCB. Aluminium puag PCB, txhuas sandwich panels, los ntawm 30 ℃ mus rau 140 ~ 150 ℃, hloov loj 2.5 ~ 3.0%.

屏蔽 性

Shielding

Kev sib txuas lus, Txheej txheem luam ntawv; Kev sib txuas lus nrog kev sib txuas lus; Txheej txheem ntawm cov khoom siv kev sib txuas lus, Txhawb Nqa Tsev Kawm Ntawv, Txhawb Nqa Tsev Kawm Ntawv, Txhawb Nqa; Thiab lub zog.

Aluminium PCB puag nrog yog shielding; tsis yog siv PCB txhuam hniav; kev siv nto fais fab kev lag luam yog ntau dua; txo cov pawg thawj coj saib xyuas thaj tsam tiag; hloov cov khoom siv hluav taws xob, tsim cov khoom thermal thiab lub cev zoo; thiab txo qhov tsim nqi thiab kev ua haujlwm.
