Automotive Aluminium PCB

Automotive electronics yog nce compact, muaj zog, thiab cua sov-sensitive. Los ntawm lub tsheb teeb pom kev zoo thiab lub zog tswj modules mus rau cov sensors, EV-txog cov tshuab, thiab cov tswj hwm, PCB yuav tsum txhawb nqa hluav taws xob ruaj khov, muaj zog thermal tswj, txhim khu kev qha rwb thaiv tsev, thiab ntev -lub sij hawm durability. Piv nrog rau cov qauv FR4 boards, aluminium-raws li PCBs muaj kev sib kis tau zoo dua thiab kev txhawb nqa tshuab, ua rau lawv tsim nyog rau cov khoom siv tsheb uas ua haujlwm nyob rau hauv qhov kub thiab txias, kev vibration, thiab hluav taws xob txuas ntxiv.

PebAutomotive Aluminium Printed Circuit Boardcov kev daws teeb meem yog tsim los pab cov neeg siv khoom daws cov teeb meem tshwm sim xws li overheating, voltage poob, tsis zoo solderability, tsis txaus rwb thaiv tsev, vibration- cuam tshuam tsis ua hauj lwm, tsis kaj siab, thiab inconsistent batch zoo. Peb txhawb nqa tsheb teeb pom kev zoo modules, lub teeb taub hau, teeb lub teeb, DRL, sab hauv teeb pom kev zoo, lub hwj chim tswj lub rooj tsavxwm, EV-cov modules, sensors, thiab lwm yam tsheb hluav taws xob siv.

Rau cov neeg siv khoom siv tsheb, qhov kev txhawj xeeb tseem ceeb tsis yog tias lub rooj tsav xwm tuaj yeem tsim tau, tab sis seb nws puas tuaj yeem nyob ruaj khov tom qab- lub sijhawm ua haujlwm ntev, thermal cycling, vibration, thiab ntau lawm. Tias yog vim li cas peb tsom rau kev xaiv cov khoom, thermal kev ua tau zoo, dielectric kev ntseeg tau, tooj liab thickness tswj, nto tiav zoo, thiab nruj soj ntsuam ua ntej xa zaub mov.

Thaum tshav kub kub dissipation yog ib qho tseem ceeb tshaj yuav tsum tau rau automotive txhuas PCBs. Ntau lub tsheb hluav taws xob cov khoom tsim hluav taws xob thaum lub sijhawm ua haujlwm, tshwj xeeb tshaj yog cov teeb pom kev zoo LED, lub zog hluav taws xob, thiab cov tshuab tswj kev sib cog lus. Yog tias cov cua sov tsis tuaj yeem hloov mus tau zoo, cov khoom siv yuav muaj hnub nyoog sai dua, LED qhov ci tuaj yeem txo qis, cov pob qij txha tuaj yeem ua tsis muaj zog, thiab cov khoom kawg yuav ua tsis tau sai dua li qhov xav tau.

Ib qho txhuas-raws li PCB muab txoj hauv kev thermal zoo dua los ntawm kev xa cov cua sov los ntawm txheej tooj liab los ntawm txheej dielectric mus rau aluminium substrate. Qhov no pab txo qis qhov kub thiab txias hauv zos thiab txhawb kev ruaj khov ntev dua - lub sijhawm ua haujlwm. Rau lub teeb taub hau, lub teeb lub teeb, lub teeb ua haujlwm nruab hnub, thiab siab - lub zog hluav taws xob, kev siv hluav taws xob zoo tuaj yeem txhim kho kev ntseeg tau thiab lub neej ntawm cov khoom.

Cov neeg siv khoom feem ntau nug seb lub rooj tsavxwm puas tuaj yeem tswj lawv cov haujlwm tam sim no, theem hluav taws xob, thiab ib puag ncig kev teeb tsa. Peb tuaj yeem pab txheeb xyuas LED lub zog, qhov dav dav, tooj liab tuab, cov khoom siv hluav taws xob, thiab lub rooj tsavxwm tuab kom pom zoo rau cov tswv yim thermal.

Thermal conductivity cuam tshuam sai npaum li cas cov cua sov txav los ntawm cov khoom mus rau aluminium puag. Rau cov khoom siv tsheb, qhov no yog qhov tseem ceeb tshwj xeeb vim tias muaj ntau lub modules tau nruab rau hauv ib puag ncig lossis siab - qhov kub thiab txias. Ib lub rooj tsavxwm uas muaj cov thermal conductivity tsis zoo yuav dhau qhov kev sim ua haujlwm luv luv tab sis ua tsis tiav thaum lub sijhawm siv sijhawm ntev -.

Cov txheej txheej dielectric yog cov qauv tseem ceeb hauv aluminium PCB. Nws yuav tsum hloov cov cua sov thaum tswj hluav taws xob rwb thaiv tsev ntawm cov tooj liab thiab cov hlau puag. Cov ntawv thov sib txawv xav tau cov thermal conductivity sib txawv. Cov teeb pom kev zoo hauv tsheb yuav siv cov khoom siv sib npaug, thaum siab - lub teeb pom kev zoo lossis EV- hais txog hluav taws xob yuav xav tau kev ua haujlwm zoo dua thermal.

Automotive ib puag ncig feem ntau suav nrog kev hloov pauv kub, thermal cycling, thiab lub sijhawm ua haujlwm ntev. PCB siv hauv tsheb hluav taws xob yuav tsum nyob ruaj khov raws li cov xwm txheej no. Cov neeg siv khoom feem ntau txhawj xeeb txog kev delamination, sib koom ua ke qaug zog, dielectric aging, solder mask discoloration, los yog kev ua tau zoo hloov tom qab rov ua cua sov thiab txias.

Thermal stability nyob ntawm cov khoom siv, dielectric zoo, tooj liab adhesion, solder daim npog qhov ncauj kev ua tau zoo, thiab nto tiav. Rau cov khoom siv teeb pom kev zoo, lub rooj tsavxwm tuaj yeem raug tshav kub tas li los ntawm cov khoom siv LED. Rau cov fais fab modules, lub thermal load yuav hloov thaum lub sij hawm ua hauj lwm. Cov qauv txhuas PCB ruaj khov pab txo qis ntev - lub sij hawm kev cia siab rau kev txaus ntshai.

Peb xyuam xim rau cov khoom sib txuam, kev sib txuas ntawm tooj liab, dielectric txheej zoo, thiab kev soj ntsuam zaum kawg los pab cov neeg siv khoom ua tiav kev ua haujlwm ruaj khov hauv kev thov kev siv tsheb.

 

Kev ruaj ntseg rwb thaiv tsev yog qhov tseem ceeb vim tias aluminium yog conductive. Lub dielectric txheej yuav tsum cais cov tooj liab Circuit Court los ntawm aluminium puag thaum tseem hloov cov cua sov. Yog tias cov rwb thaiv tsev ua haujlwm tsis zoo, cov neeg siv khoom yuav ntsib kev pheej hmoo tawg, cov dej xau tam sim no, luv Circuit Court, lossis kev nyab xeeb tsis ua haujlwm.

Automotive cov neeg muas zaub feem ntau mob siab rau dielectric zog, rwb thaiv tsev tsis kam, creepage nrug, clearance, thiab kev nyab xeeb qhov chaw. Rau siab- zog lossis siab dua- cov ntawv siv hluav taws xob, kev tsim hluav taws xob rwb thaiv tsev yuav tsum tau tshuaj xyuas ua ntej tsim khoom. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau lub teeb pom kev tsheb, EV- hais txog hluav taws xob, thiab cov tswj fais fab.

 

Kev txhim khu kev qha aluminium PCB yuav tsum sib npaug thermal conductivity thiab hluav taws xob kev nyab xeeb. Xaiv tsuas yog cov khoom siv thermal conductivity siab yam tsis xav txog lub zog dielectric yuav ua rau muaj kev pheej hmoo ntev -. Peb pab cov neeg siv khoom xaiv cov khoom siv hluav taws xob tsim nyog raws li qhov hluav taws xob, lub zog, thiab kev nyab xeeb.

Kev xaiv cov khoom siv yuav tsum phim cov khoom lub zog, qhov kub thiab txias, qhov hluav taws xob, txoj kev sib dhos, thiab cov phiaj xwm nqi. Automotive cov neeg siv khoom feem ntau nug seb qhov twg aluminium thickness, tooj liab thickness, dielectric khoom, thiab nto tiav yuav tsum tau xaiv. Qhov kev xaiv zoo tshaj yog nyob ntawm daim ntawv thov tiag tiag es tsis yog qhov tshwj xeeb tshaj plaws.

Cov khoom siv zoo tuaj yeem pab cov neeg siv khoom kom tsis txhob overheating, rwb thaiv tsev tsis ua haujlwm, soldering tsis xws luag, thiab cov nqi tsis tsim nyog.

Kev tswj hwm nruj yog qhov tseem ceeb rau kev tsav tsheb aluminium PCBs vim tias kev ua tsis tiav yuav ua rau cov khoom xa rov qab, cov nqi lav, lossis qhov system tsis ruaj khov. Kev tshuaj xyuas yuav tsum tsis tsuas yog qhib thiab luv luv Circuit Court, tab sis kuj thermal dielectric zoo, tooj liab thickness, solder daim npog qhov ncauj, nto tiav, qhov ntev, rwb thaiv tsev kev ua tau zoo, thiab batch sib xws.

Peb qhov kev tswj xyuas zoo tuaj yeem suav nrog kev tshuaj xyuas cov khoom siv, tooj liab thickness tswj, dielectric txheej tshuaj xyuas, tshuaj xyuas lub npog ntsej muag, kev tshuaj xyuas qhov chaw tiav, AOI tshuaj xyuas, kev kuaj hluav taws xob, kev tshuaj xyuas qhov ntev, kev tshuaj xyuas qhov muag, kev ntsuam xyuas rwb thaiv tsev yog tias xav tau, thiab kev tiv thaiv ntim zaum kawg.

Rau kev txiav txim rov qab, kev tswj cov txheej txheem ruaj khov thiab cov ntaub ntawv batch pab cov neeg siv khoom tswj hwm kev ua tau zoo los ntawm cov qauv mus rau ntau lawm.
