6.FAQ
Q: Kuv puas yuav tsum tau siv ib qho khoom siv FR4 nrog lub siab Tg (Tg = iav hloov mus hloov) rau cov kab mob tsis muaj lead?
Tsis yog, tsis tas. Muaj ntau ntau yam yuav raug coj mus rau hauv tus as khauj, xws li tshooj ntau npaum li cas, lub thickness ntawm PCB thiab tseem muaj kev nkag siab zoo ntawm txoj kev sib dhos (cov xov tooj ntawm cov voj voog, lub sij hawm saum 260 degrees, thiab lwm yam). Tej kev tshawb fawb tau pom tias cov khoom siv nrog tus "standard" Tg tus nqi tseem ua tau zoo dua li cov khoom siv nrog tus nqi siab dua Tg. Nco ntsoov tias txawm tias "leaded" txhais tau tias muaj tus nqi Tg ntau tshaj.
Dab tsi yog qhov tseem ceeb tshaj plaws yog qhov cov khoom siv thaum kub tshaj tus nqi zog ntawm Tg (tom qab Tg) thiaj paub txog qhov kub thiab txias txias ntawm lub Rooj Tswjhwm Saib cov no yuav ua rau koj saib xyuas qhov kev ntsuam xyuas tus yam ntxwv tsim nyog.
Lus Nug: Cov yam ntxwv ntawm cov khoom los saib thaum xaiv cov khoom dab tsi?
Cov sawv daws tseem ceeb tshaj plaws uas peb xav txog yog: CTE
Ib qho kev ntsuas ntawm ntau npaum li cas cov khoom nthuav thaum kub. Tseem ceeb nyob rau hauv Z-axis - feem ntau saum Tg thiab nthuav yog qhov ntau dua. Yog tias CTE tsis txaus ua rau kev poob siab tuaj yeem tuaj yeem tshwm sim thaum sib sau ua ke raws li cov khoom nthuav dav sai tshaj Tg. 
Sab laug duab: Chaav tawg / tawg qhov Txoj cai duab: Tsav av
Cov ntaub ntawv tuaj yeem muaj Tg tib yam tsis tau CTE tus kheej - qis dua CTE zoo dua. Qee yam ntaub ntawv muaj peev xwm siab dua Tg qhov tseem ceeb, tseem tau muaj CTE ncej dua (zuj zus).
TG / GLASS TRANSITION TXIAB
Tg tus nqi yog qhov kub ntawm qhov khoom hloov ntawm cov khoom zoo li lub iav uas zoo li siv rau cov ntaub ntawv zoo li ywj thiab cov khoom zoo li yas. Tseem ceeb raws li saum Tg, cov ntaub ntawv cov khoom yuav hloov.
Td / DECOMPOSITION TEMPERATURE
Qhov no yog ib qho kev ntsuas ntawm qhov degredation ntawm cov khoom. Kev ntsuam xyuas tus qauv ntsuas thaum 5% ntawm cov khoom poob ntawm qhov hnyav - qhov taw tes raws li qhov kev ntseeg muaj kev ruaj ntseg thiab kev thev taus yuav tshwm sim.
Kev ntseeg siab dua PCB yuav xav tau Td ≥ 340 ℃
T260 / T288 / LUB SIJ HAWM LOS YOG DELAMINATION
Qhov no yog txoj kev txiav txim siab txog lub sijhawm thaum lub teeb meem ntawm PCB yog hloov tsis tau ntawm qhov kev ntsuas cua txias (260 los sis 288 nyob rau hauv rooj plaub no) - piv txwv li thaum cov khoom nthuav txog xws li ib qho degree uas nws delaminates.
Lus Nug: Kuv puas yuav tsum tau siv ib qho khoom siv FR4 nrog lub siab tshaj plaws Td (Td = decomposition temperature) rau cov kab mob tsis muaj lead-free?
Ib qho txiaj ntsim Td ntau dua yog qhov tshwj xeeb, tshwj xeeb tshaj yog yog hais tias pawg thawj coj saib kev lag luam muaj kev sib txuas thiab raug rau ntau cov khoom txeem, tab sis qhov no tuaj yeem ua rau cov nqi ntau dua. Kev paub txog koj lub rooj sib txoos ua ke tuaj yeem pab xaiv txoj kev xaiv.
