Kev tshuaj xyuas txheej txheem txheej txheej ntawm FR4 epoxy iav fiber board

FR4 epoxy iav fiber ntau lub rooj tsavxwm tuaj yeem muab kev ua si tag nrho rau nws cov khoom siv hauv nruab nrab kub; nyob rau hauv ib puag ncig kub kub, nws tuaj yeem muab kev ua si tag nrho rau nws cov khoom hluav taws xob. Yog li ntawd, vim yog cov yam ntxwv no, epoxy board yog qhov tsim nyog rau cov khoom siv hluav taws xob zoo hauv hluav taws xob thiab hluav taws xob. Nws muaj zog dua txhua yam thiab tsis kam tiv thaiv hluav taws xob ntau dua li lub teb chaws tus qauv 3240 board.

FR4 epoxy iav fiber board cov kauj ruam tseem ceeb suav nrog cua sov, nias, kho, txias, demoulding thiab lwm yam.

Hais txog txheej txheem lamination ntawm FR4 epoxy iav fiber board

1. Ua ntej cua sov theem: Muab cov ntawv epoxy tso rau hauv qhov kub nias thiab ua kom sov nws li 30 feeb ntawm qhov kub txog 120 ° C, yog li cov epoxy cob thiab cov khoom siv txhawb nqa tau ua tiav, thiab cov volatiles kuj tau ntws los. Cov kauj ruam no tseem ceeb heev. Yog tias lub sijhawm luv luv thiab qhov kub tsis txaus, nws yog qhov yooj yim los tsim cov npuas, yog tias qhov kub thiab txias thiab lub sijhawm ntev dhau lawm, qhov khoob yuav plam tawm.

2. Kub xovxwm molding theem: nyob rau theem no, qhov kub thiab txias, lub sijhawm, thiab lub siab yuav muaj kev cuam tshuam ncaj qha rau cov khoom kawg, thiab cov yam ntxwv no yuav tsum tau hloov tas li nyob ntawm cov khoom siv. Piv txwv li, nyob rau hauv cov ntaub ntawv ntawm epoxy phenolic laminated daim ntaub, qhov kub yog teem rau ntawm 170 ° C, thiab nyob rau hauv cov ntaub ntawv ntawm epoxy silicone iav ntaub, qhov kub yog teem ntawm txog 200 ° C. Yog hais tias lub rooj tsavxwm yog thinner, txo cov cua kub nias.

3. Txias thiab demoulding: Tom qab nias, muab cov ntawv epoxy tso rau hauv dej txias kom txias, lub sijhawm nyob nruab nrab ntawm ib nrab teev thiab ib teev. Thaum lub sijhawm no, kev saib xyuas yuav tsum tau them rau kev hloov pauv ntawm kev ntxhov siab sab hauv. Kev nthuav tawm cov cua sov ntau dhau thiab kev sib cog lus yuav ua rau lub rooj tsav tsheb laminated ua rau lub kaum ntse ntse thiab hloov pauv.

1. Tom qab kev kho mob: Cov kauj ruam no yog ua kom qhov kev ua tau zoo ntawm epoxy board zoo dua. Piv txwv li, muab cov khoom tsim tawm rau hauv qhov cub rau kev kho cua sov tuaj yeem tshem tawm cov kev ntxhov siab sab hauv.
