Ukuhlaziywa kwenqubo yokuhlanza ye-FR4 epoxy glass fiber board

I-FR4 epoxy glass fiber board inganikeza ukudlala okugcwele kuzakhiwo zayo zomshini ngaphansi kwezinga lokushisa eliphakathi; ngaphansi kwezinga lokushisa okuphezulu, inganikeza ukudlala okugcwele kuzakhiwo zayo zikagesi. Ngakho-ke, ngenxa yalezi zici, ibhodi ye-epoxy ilungele kakhulu izingxenye zokwakheka okuphezulu emikhakheni kagesi neye-elekthronikhi. Inamandla aphakeme womshini nokumelana nokwehla kwamandla kagesi kunebhodi ejwayelekile kazwelonke engama-3240.

Izinyathelo eziyinhloko ze-FR4 epoxy glass board board zifaka ukushisa, ukucindezela, ukwelapha, ukupholisa, ukudiliza nokunye.

Mayelana nenqubo yokuvikela ngocwazi ibhodi le-fiber le-FR4 epoxy

1. Isiteji sangaphambi kokushisa: Beka ibhodi ye-epoxy kumshini oshisayo bese uyishisa imizuzu engama-30 ezingeni lokushisa elilinganiselwa ku-120 ° C, ukuze i-resin ye-epoxy nezinto eziqinisayo zihlanganiswe ngokuphelele, futhi iziphithiphithi nazo zigcwala ngokweqile. Lesi sinyathelo sibucayi kakhulu. Uma isikhathi sifushane kakhulu futhi nezinga lokushisa alanele, kulula ukukhiqiza amabhamuza, uma izinga lokushisa liphezulu kakhulu futhi nesikhathi side kakhulu, okungenalutho kuzophuma.

2.Isigaba sokubumba sabezindaba esishisayo: Kulesi sigaba, izinga lokushisa, isikhathi, nengcindezi kuzoba nomthelela oqondile kumkhiqizo wokugcina, futhi lezi zinto kufanele zishintshe njalo kuye ngokuthile. Isibonelo, esimweni sendwangu e-epoxy phenolic laminated, izinga lokushisa lisethwe cishe ku-170 ° C, futhi endabeni yendwangu yengilazi ye-epoxy, izinga lokushisa lisethwe cishe ku-200 ° C. Uma ibhodi lincane, yehlisa ukushisa kokucindezela ukushisa.

3. Ukupholisa nokudiliza: Ngemuva kokucindezela, faka ibhodi le-epoxy emanzini abandayo ukuze aphole, isikhathi siphakathi kwengxenye yehora nehora elilodwa. Ngalesi sikhathi, kufanele kunakwe ekushintsheni kwengcindezi yangaphakathi. Ukwanda ngokweqile kokushisa nokunciphisa kuzodala ukuthi ibhodi elinamaminerali limboze futhi likhubaze.

Ngemuva kokwelashwa: Lesi sinyathelo sokwenza ukusebenza kwebhodi le-epoxy kuphakeme kakhulu. Isibonelo, ukufaka ibhodi elikhiqizwayo kuhhavini ukwelashwa ukushisa kungaqeda izinsalela zokucindezeleka kwangaphakathi.
