1, Taw qhia rau PCB board
PCB board, tseem hu ua cov khoom siv hauv Circuit Court board, yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob. Nws feem ntau yog tsim los ntawm cov ntaub ntawv xws li substrate, copper foil, thiab solder resist. Lub substrate tuaj yeem yog iav fiber ntau, polyimide, epoxy resin, thiab lwm yam. Copper foil yog txheej txheej txheej txheej rau kev ua circuits, thaum solder tiv thaiv yog siv los npog qhov chaw tsis pom kev rau kev ntxig lossis phau ntawv soldering. Qhov kev ua tau zoo ntawm lub substrate, tooj liab txheej thickness, thiab lub qhov tooj liab thickness yog cov cim tseem ceeb rau kev ntsuam xyuas qhov zoo ntawm PCB boards.
2, Qhov tseem ceeb ntawm PCB tooj liab txheej thickness
Lub thickness ntawm PCB tooj liab txheej yog hais txog lub thickness ntawm cov ntawv ci tooj liab npog qhov chaw ntawm lub rooj tsav xwm Circuit Court. Feem ntau hais lus, qhov tuab ntawm tooj liab txheej ntawm lub rooj tsavxwm, qhov zoo dua nws cov conductivity thiab tshav kub dissipation muaj peev xwm. Yog li ntawd, nyob rau hauv kev tsim thiab tsim cov txheej txheem ntawm PCB boards, nws yog tsim nyog los xaiv qhov tsim nyog tooj liab txheej thickness raws li ib tug tshwj xeeb daim ntawv thov scenarios thiab yuav tsum tau kom lub stability thiab kev cia siab ntawm lub Circuit Court board kev ua tau zoo.
Tam sim no, cov txheej txheem rau PCB tooj liab txheej thickness tau maj mam hloov kho, feem ntau muab faib ua ntau theem xws li 1oz, 2oz, 3oz, 4oz, thiab lwm yam. Ntawm lawv, tooj liab txheej thickness ntawm 1oz tau dhau los ua tus qauv rau cov khoom siv hluav taws xob, thaum tooj liab txheej thickness ntawm 2oz los yog saum toj no yog siv rau qee lub sijhawm tshwj xeeb, xws li lub zog loj LED teeb.
3, Qhov tseem ceeb ntawm tooj liab Thickness hauv PCB Qhov
Lub thickness ntawm PCB qhov tooj yog hais txog qhov sib piv ntawm cov thickness ntawm cov tooj liab txheej ntawm lub puab phab ntsa ntawm lub qhov tooj liab mus rau qhov deb ntawm lub qhov phab ntsa. Feem ntau, cov dej ntws ntawm cov hluav taws xob siv nyob rau hauv qhov ntawm PCB boards yuav ntws mus rau ntawm lub qhov phab ntsa los ntawm cov tooj liab txheej txheej, yog li tsim txoj hauv kev tam sim no. Yog tias cov txheej tooj liab ntawm lub qhov phab ntsa yog nyias dhau, txoj kev ntws tam sim no yuav raug txwv, uas ua rau muaj kev puas tsuaj rau kev ua haujlwm ntawm tag nrho cov Circuit Court. Yog li ntawd, nyob rau hauv kev tsim thiab tsim cov txheej txheem ntawm PCB boards, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj lub thickness ntawm tooj liab qhov los xyuas kom meej qhov kev ua tau zoo thiab kev ruaj ntseg ntawm lub Circuit Court board.
Tam sim no, tus qauv rau PCB qhov tooj liab tuab kuj tau hloov kho dua tshiab, feem ntau muab faib ua ntau theem xws li 0.5oz, 1oz, 2oz, thiab lwm yam. Ntawm lawv, 1oz qhov tooj liab thickness tau dhau los ua tus qauv rau hluav taws xob. cov khoom, thaum lub 2oz qhov tooj liab thickness yog tsuas yog siv rau tshwj xeeb zaus xws li high-power electronic khoom.
