Npaum li cas multilayer board laminated li cas?

Laminating yog txheej txheem ntawm tsevneeg txhua txheej txheej ntawm daim ntawv xev hluav taws xob rau hauv tag nrho. Tag nrho cov txheej txheem suav nrog hnia nias, nias tag nrho thiab txias nias. Nyob rau hauv lub hnia siab theem, cov roj nplaum infiltrates qhov sib txuas thiab ua kom tiav cov khoob hauv Circuit Court, thiab tom qab ntawd nkag mus rau tag nrho lub siab los txhawm rau txhua qhov khoob. Cov ntawv hu ua txias nias yog kom ceev nrawm lub rooj tsav xwm hauv Circuit Court thiab ua kom qhov luaj li cas ruaj khov. Cov teeb meem xav tau kev saib xyuas hauv cov txheej txheem lamination. Ua ntej txhua yam, hauv kev tsim qauv, sab hauv cov tub ntxhais hauv lub rooj tsav khoom uas yuav tsum ua tau raws li cov cai ntawm lamination, feem ntau yog tuab, qhov ntev sab nraud, qhov chaw tso, thiab lwm yam, yuav tsum tsim qauv raws li qhov tshwj xeeb. Nyob rau hauv dav dav, sab hauv lub rooj tsavxwm Tsis muaj qhib, luv, qhib Circuit Court, tsis muaj oxidation thiab tsis tas zaj duab xis seem. Thib ob, thaum lub multilayer board yog laminated, sab hauv pawg thawj coj xav tau kev coj ua. Lub thev naus laus zis suav nrog kev kho cov hlau oxidation dub thiab kho xim. Qhov kev kho oxidation yog los ua cov yeeb yaj kiab dub oxide ntawm daim ntawv tooj liab sab hauv, thiab txheej txheem txheej txheem xim av yog tsim cov organic ua rau ntawm cov ntawv ci tooj liab sab hauv. Thaum kawg, thaum laminating, koj yuav tsum them sai sai rau peb qhov teeb meem loj ntawm qhov kub thiab txias, siab, thiab sijhawm. Kev ntsuas kub, feem ntau them rau kub melting thiab solidification kub ntawm cov roj, qhov ntsuas kub ntawm lub phaj kub, qhov ntsuas kub tiag tiag ntawm cov khoom thiab qhov hloov ceev ntawm qhov kub nce, thiab lwm yam Cov ntsiab lus no xav tau kev saib xyuas. Raws li rau lub siab, lub hauv paus ntsiab lus yog los sau cov voids ntawm cov khaubncaws sab nraud povtseg nrog cov roj thiab tso cov pa thiab cov tawm ntawm cov txheej txheej. Lub sijhawm tsis suav feem ntau suav nrog kev tswj cov pa hluav taws xob lub sijhawm, kev tswj cua sov sijhawm thiab gel lub sijhawm.
