(1) Resin kua nplaum kua mis Ua haujlwm hauv epoxy resin fiberglass board kev lag luam, FR-4 fiberglass board tau tsim rau ntau xyoo, thiab cov kua nplaum kua mis ua kua mis yog qhov zoo ib yam.
(2) Txoj kev npaj: 1) Dimethylformamide thiab ethylene glycol methyl ether yog do thiab tov los npaj cov tshuaj hnyav. 2) Ntxiv rau dicyandiamide thiab do kom yaj. 3) Ntxiv epoxy resin thiab do kom tov. 4) 2-Methylimidazole yog pre-yaj nyob rau hauv ib qho tsim nyog ntawm dimethylformamide, tom qab ntawd ntxiv rau cov ntaub ntawv saum toj no, thiab txuas ntxiv mus do tag nrho. 5) Tom qab nres tsheb (kho) rau 8 teev, coj mus kuaj thiab ntsuas cov khoom tsim nyog yuav tsum tau ua.
(3) Cov kev cai xav tau rau cov kua nplaum nplaum: 1) Cov ntsiab lus tsis ruaj yog 65% mus rau 70%. 2) Lub sijhawm Gel (171 ℃) 200 ～ 250s.
