Cov kev xav tau yooj yim rau kev ua haujlwmntawm Tsheb Circuit Board Assembly

a. Kev ntseeg siab

Automotive kev ntseeg siab feem ntau yog los ntawm ob yam: lub neej ntev thiab kev tiv thaiv ib puag ncig. Tus qub yog hais txog qhov tseeb tias kev ua haujlwm ib txwm muaj peev xwm lav tau nws lub neej kev pabcuam, thaum lub sijhawm tom kawg yog hais txog qhov tseeb tias qhov kev ua haujlwm ntawm PCB tseem zoo li qub thaum ib puag ncig hloov pauv.

b. Lub teeb nyhav thiab me me

Lub teeb, lub tsheb me me yog qhov zoo rau kev txuag hluav taws xob. Lub teeb los ntawm kev txo qhov hnyav ntawm txhua yam khoom. Piv txwv li, qee qhov hlau yog hloov los ntawm engineering yas qhov chaw. Tsis tas li ntawd, ob qho tib si automotive electronics thiab PCBs yuav tsum tau miniaturized. Piv txwv li, qhov ntim ntawm ECU (Electronic Control Unit) hauv kev siv tsheb yog li ntawm 1200 cm3 pib xyoo 2000, thaum tsawg dua 300 cm3, poob los ntawm plaub zaug. Tsis tas li ntawd, qhov pib phom phom tau hloov pauv los ntawm cov khoom siv phom sib txuas los ntawm cov xov hlau mus rau cov phom hluav taws xob txuas nrog cov xov hlau hloov tau yooj yim nrog PCB sab hauv, txo qhov ntim thiab qhov hnyav ntau dua 10 zaug.

Lub teeb yuag thiab miniaturization ntawm PCBs pib los ntawm kev nce hauv qhov ntom ntom, txo qis hauv cheeb tsam, txo cov thickness thiab ntau txheej.

Manufacturing yam ntxwv ntawmTsheb Circuit Board Assembly

(1) High zaus substrate

Automotive kev sib tsoo kev zam / kev kwv yees braking kev ruaj ntseg tshuab ua haujlwm raws li cov khoom siv tub rog radar. Txij li cov tsheb PCBs yog lub luag haujlwm rau kev xa cov teeb liab microwave high-frequency, lub substrate uas tsis tshua muaj dielectric poob yuav tsum tau siv ua ke nrog cov khoom siv substrate PTFE. Tsis zoo li FR4 cov ntaub ntawv, PTFE los yog cov ntaub ntawv zoo sib xws high zaus matrix yuav tsum tau tshwj xeeb drilling ceev thiab pub tus nqi thaum lub sij hawm drilling txheej txheem.

(2) Thick tooj liab PCB

Vim tias qhov siab ceev thiab muaj zog thiab cov hluav taws xob siv hluav taws xob, thiab hluav taws xob hluav taws xob ua kom muaj zog ntau dua rau cov kev tsis txaus siab thiab kub tam sim no. Xav tau.

Ua ib tug tuab tooj liab ob txheej PCB yog ib qho yooj yim, thaum ua ib tug tuab tooj liab multilayer PCB yog ntau nyuaj. Qhov tseem ceeb yog tuab tooj liab duab etching thiab tuab vacancy filling.

Cov txheej txheem sab hauv ntawm cov tuab tooj liab multilayer PCB yog txhua tus tooj liab tuab, yog li cov qauv hloov pauv cov duab thaij duab kuj tseem yog tuab, uas yuav tsum tau muaj kev tiv thaiv siab heev. Cov qauv etching lub sij hawm ntawm cov tooj liab tuab yuav ntev, thiab cov khoom siv etching thiab cov txheej txheem kev ua haujlwm yog nyob rau hauv qhov zoo tshaj plaws los xyuas kom meej tag nrho routing ntawm tuab tooj liab. Thaum ua cov txheej txheem sab nraud tuab tooj liab, kev sib xyaw ua ke ntawm laminating ib co copper foil tuab thiab qauv txheej tooj liab tuab tuaj yeem ua tau ua ntej, ua raws li zaj duab xis void etching. Cov zaj duab xis qhuav tiv thaiv ntawm cov qauv plating kuj yog tuab.

Qhov sib txawv ntawm qhov sib txawv ntawm tus neeg xyuas pib ntawm cov tuab tooj liab multilayer PCB thiab cov khoom siv insulating substrate yog qhov loj, thiab cov txheej txheem multilayer zoo tib yam lamination tsis tuaj yeem sau tag nrho cov resin, ua rau muaj kab noj hniav. Yuav kom daws tau qhov teeb meem no, nyias prepregs nrog cov ntsiab lus siab resin yuav tsum tau siv ntau li ntau tau. Lub thickness ntawm tooj liab ntawm sab hauv routing ntawm ib co multilayer PCBs tsis yog ib yam, thiab txawv prepregs yuav siv tau nyob rau hauv cov cheeb tsam nrog loj los yog me me sib txawv ntawm tooj liab thickness.

(3) Cov khoom sib xyaw

Txhawm rau nce kev sib dhos ua si thiab txo qis qhov loj me, PCBs nrog cov khoom siv hauv lub xov tooj ntawm tes, uas tseem yuav tsum muaj rau lwm yam khoom siv hluav taws xob. Yog li ntawd, cov khoom siv hauv PCBs kuj tseem siv rau hauv cov khoom siv hluav taws xob hauv tsheb.
