Aluminium puag pcb , peb txhua tus paub tias txhuas yog hlau, hluav taws xob kev coj ua;

Yuav ua li cas nws siv tau los ua cov khoom siv PCB?

Vim tias txhuas txheej txheej txheej yog tsim ntawm peb txheej, uas yog: tooj liab ntawv ci, txheej txheej rwb thaiv tsev thiab nws yog xim hlau txhuas.Vim muaj txheej txheej insulating, ntxiv rau qhov ua kom muaj cua sov ua kom sov, cov thermal expansion coefficient, thermal conductivity, lub zog, tawv, lub cev hnyav, qhov teeb meem saum npoo thiab tus nqi ntawm cov hlau substrate yuav tsum tau txiav txim siab.

Nyob rau hauv dav dav, xav txog tus nqi thiab kev ua haujlwm, aluminium substrate yog qhov kev xaiv zoo tshaj plaws.Available txhuas phaj 6061,5052,1060, etc.Copper substrates kuj tseem muaj rau kev ua haujlwm siab dua thermal, mechanical, hluav taws xob, thiab lwm yam khoom tshwj xeeb, tab sis kim dua Cov.

Nws feem ntau pom ntawm ob tog ntawm txhuas substrate PCB. Ib sab nrog roj npog yog welded nrog LED pins, thaum lwm sab pom cov xim qub ntawm txhuas. Feem ntau, cov thermal conductive paste yuav siv thiab tom qab ntawd tiv tauj nrog cov thermal conductive ib feem.One ntawm qhov zoo tshaj plaws ntawm txhuas txheej tshaj li cov tsoos FR-4 yog tias lawv tuaj yeem nqa hluav taws xob ntau dua.Thiab ua kom muaj cua sov ceev, zoo tshav kub dissipation zoo.

Aluminium substrate tuaj yeem txo qhov kub tsis kam ua kom qhov tsawg kawg nkaus, kom cov aluminium substrate muaj kev ua tau zoo thaum tshav kub kub; Piv nrog ceramic substrate, nws cov cuab yeej muaj zog yog qhov zoo heev.Txhais ntxiv rau qhov ua kom zoo cua sov ua kom zoo;

Aluminium substrate kuj muaj cov zoo li nram no:

Raws li RoHS ib puag ncig kev tiv thaiv kev tiv thaiv, nws zoo dua rau SMT cov txheej txheem nrog lub siab dua tam sim no nqa lub peev xwm los tiv thaiv cov cua sov tsis sib txawv hauv cov qauv tsim hluav taws xob, kom thiaj li txo qhov module ua haujlwm kub, txuas lub neej kev pab, thiab txhim kho lub zog ceev thiab kev ntseeg tau;

Txo txo ​​lub rooj sib txoos ntawm cov hluav taws xob thiab lwm cov khoom siv (suav nrog cov khoom siv hluav taws xob interface), txo cov khoom ntim, thiab txo cov nqi kho vajtse thiab sib dhos;

Qhov saum toj no yog hais txog qhov zoo ntawm aluminium substrate, Kuv vam tias koj yuav nyiam nws! Peb yog lub PCB Hoobkas , txais tos koj sab laj rau peb cov khoom lag luam PCB ~
