Embodiment 1
[0032] Dissolve 100 parts by weight of styrene-butadiene block copolymer (D1101) in toluene, add 85 parts by weight of silicon dioxide (525), 6.5 parts by weight of curing agent DCP, 22 parts by weight of The fuel SAYTEX8010 was stirred to obtain a resin solution (80% solid content), and 80 parts by weight of 1080 fiberglass cloth was used to impregnate the above resin solution to obtain a prepreg. Then dry the prepreg to remove the solvent. Laminate 8 prepregs, laminate copper foil on both sides, and heat and press in a press to make a flame-retardant electronic composite substrate.
[0033] In this embodiment, the particle size of the filler is 30-40 microns; the copper foil is 1 ounce copper foil, and the copper nodule height of the copper foil is 9-10 microns; the rough surface of the copper foil is passed through the vinyl coupling agent vinyl trimethyl Silane treatment; copper nodules are prepared on one side of the rolled copper foil or electrolytic copper foil to form...
Embodiment 2
[0036] Dissolve 100 parts by weight of styrene-butadiene block copolymer (D1101) in toluene, add 240 parts by weight of silicon dioxide (525), 7.5 parts by weight of curing agent DCP, 28 parts by weight of Combustion agent SAYTEX8010, stir to obtain resin liquid (solid content is 80%), use 125 parts by weight of 1080 fiber glass cloth to impregnate the above resin liquid and then dry to remove solvent to make prepreg, then stack 8 prepregs, place on both sides Laminated copper foil, after high-temperature hot-press curing in a press, is made into a flame-retardant electronic composite substrate; the drying temperature is 100°C, and the time is 3 minutes; the hot-pressing temperature is 250°C, and the time is 50 minutes. The pressure is 70kg / cm 2 ; Its physical data are shown in Table 1.
