FR4 epoxy glass ifayibha inkqubo laminating

Amanyathelo aphambili ebhodi ye-FR4 epoxy glass fiber ibandakanya ukufudumeza, ukucinezela, ukunyanga, ukupholisa, ukudiliza, njl. Inkqubo yokucoca ibandakanya amanyathelo ama-4:

1. Isiteji sokufudumala: Faka ibhodi ye-epoxy kwi-press eshushu kwaye uyitshise imizuzu engama-30 kwiqondo lokushisa malunga ne-120 ° C, ukwenzela ukuba i-epoxy resin kunye nezinto eziqiniswayo zihlanganiswe ngokupheleleyo, kwaye i-volatiles nayo iphuphuma. Eli nyathelo libaluleke kakhulu. Ukuba ixesha lifutshane kakhulu kwaye iqondo lokushisa alanelanga, kulula ukuvelisa amaqamza, ukuba iqondo lokushisa liphezulu kakhulu kwaye ixesha lide kakhulu, into engenanto iya kuphuma.

2. Inqanaba lokubumba i-Hot-press: Kweli nqanaba, ubushushu, ixesha, kunye noxinzelelo luya kuba nefuthe elithe ngqo kwimveliso yokugqibela, kwaye ezi zinto kufuneka zihlale ziguquka ngokwezinto ezahlukeneyo. Ngokomzekelo, kwimeko ye-epoxy phenolic cloth laminated cloth, iqondo lokushisa libekwe malunga ne-170 ° C, kwaye kwimeko ye-epoxy silicone glass cloth, iqondo lokushisa libekwe malunga ne-200 ° C. Ukuba ibhodi incinci, yehlisa ubushushu obucinezela ubushushu.

3. Ukupholisa kunye nokudiliza: Emva kokucinezela, faka ibhodi ye-epoxy emanzini abandayo ukupholisa, ixesha liphakathi kwesiqingatha seyure kunye neyure enye. Ngeli xesha, ingqalelo kufuneka ihlawulwe ekutshintsheni uxinzelelo lwangaphakathi. Ukwandiswa okugqithisileyo kwe-thermal kunye nokucutha kuya kubangela ukuba ibhodi elaminethiweyo idibanise kwaye iguqulwe.

4. Emva konyango: Eli nyathelo kukwenza ukusebenza kwebhodi ye-epoxy ibe ngaphezulu. Ngokomzekelo, ukubeka ibhodi eveliswayo kwi-oven ukwenzela unyango olushushu kunokuphelisa intsalela yoxinzelelo lwangaphakathi.
