Khoom Taw Qhia
RTF, rov qab kho kho electrolytic tooj liab ntawv ci yog lub tooj liab ntawv ci uas tau raug tshem tawm cov qib sib txawv ntawm ob sab. Qhov no txhawb tau lub zog tev ntawm ob sab ntawm lub tooj liab ntawv nyiaj, ua rau nws yooj yim dua los siv ua cov txheej nruab nrab rau kev sib txuas lus rau lwm cov ntaub ntawv. Ntxiv mus, cov qib sib txawv ntawm kev kho mob ntawm ob sab ntawm cov xov tooj tooj liab ua rau nws yooj yim rau etch lub thinner sab ntawm daim roughened txheej. Nyob rau hauv cov txheej txheem ntawm kev ua cov ntawv luam tawm hluav taws xob (PCB) vaj huam sib luag, kho tus tooj liab tau thov rau cov khoom dielectric. Kho lub nruas sab yog rougher dua rau lwm sab, uas suav tau ntau dua cov adhesion ntau dua rau dielectric. Qhov no yog lub ntsiab zoo tshaj cov qauv hluav taws xob electrolytic. Lub matte ib sab tsis tas yuav muaj tshuab lossis tshuaj kho mob ua ntej daim ntawv thov ntawm photoresist. Nws yog twb ntxhib txaus kom muaj lus laminating zoo tiv thaiv adchesion.
Cov lus qhia
Khi tuaj yeem muab RTF electrolytic tooj liab ntawv nyiaj nrog nominal tuab ntawm 12 txog 35μm txog 1295 hli dav.
Ua yeeb yam
Qhov kub kub elongation reversed kho electrolytic tooj liab txheej txheem los tswj qhov loj me ntawm cov liab hlav hlav thiab faib lawv tusyees. Cov thim rov qab tau kho qhov muag ci ntsa iab ntawm lub tooj liab tau muaj peev xwm txo cov rougning ntawv thiab muab txaus rau lub zog ntawm tooj liab ntawv ci. (Saib Cov Lus 1)
Cov Ntawv Thov
Yuav siv tau rau cov khoom lag luam high-zaus thiab orner Laminates, xws li 5G puag ncig thiab ntsuas hluav taws xob thiab lwm yam khoom siv.
Qhov Zoo
Zoo bonding zog, ncaj ncees txheej lamination, thiab zoo etching kev ua haujlwm. Nws tseem yuav txo cov peev xwm rau lub voj voog luv luv thiab luv cov txheej txheem voj voog.
