I-FR4 epoxy glass fiber board laminating inqubo

Izinyathelo eziyinhloko ze-FR4 epoxy glass fiber board zihlanganisa ukushisa, ukucindezela, ukuphulukisa, ukupholisa, ukudiliza, njll. Inqubo yokugcoba ihlanganisa izinyathelo ezi-4:

1. Isiteji sokushisa: Faka ibhodi le-epoxy emshinini oshisayo bese uwushisa imizuzu engu-30 ekushiseni okungaba ngu-120 ° C, ukuze i-epoxy resin kanye nezinto eziqinisayo zihlanganiswe ngokugcwele, futhi ama-volatiles nawo agcwale. Lesi sinyathelo sibucayi kakhulu. Uma isikhathi sifushane kakhulu futhi izinga lokushisa linganele, kulula ukukhiqiza ama-bubbles, uma izinga lokushisa liphezulu kakhulu futhi isikhathi siside kakhulu, okungenalutho kuzophuma.

2. Isiteji sokwenza umshini wokushisa oshisayo: Kulesi sigaba, izinga lokushisa, isikhathi, nokucindezela kuzoba nomthelela oqondile emkhiqizo wokugcina, futhi lezi zici kufanele zihlale zishintsha ngokuya ngezinto ezahlukahlukene. Isibonelo, esimweni se-epoxy phenolic laminated cloth, izinga lokushisa libekwe cishe ku-170 ° C, futhi esimweni sendwangu yengilazi ye-epoxy silicone, izinga lokushisa libekwe cishe ku-200 ° C. Uma ibhodi lincane, yehlisa izinga lokushisa lokucindezela ukushisa.

3. Ukupholisa nokudiliza: Ngemva kokucindezela, faka ibhodi le-epoxy emanzini abandayo ukuze liphole, isikhathi siphakathi kwesigamu sehora nehora elilodwa. Ngalesi sikhathi, ukunakwa kufanele kukhokhwe ekushintsheni kokucindezeleka kwangaphakathi. Ukwandiswa okushisayo nokunciphisa ngokweqile kuzobangela ibhodi elaminethiwe ukuthi ligoqe futhi liwohloke.

4. Ngemuva kokwelashwa: Lesi sinyathelo esokwenza ukusebenza kwebhodi le-epoxy kuphakame kakhulu. Isibonelo, ukubeka ibhodi elikhiqiziwe kuhhavini ukuze uthole ukwelashwa kokushisa kungaqeda insalela yokucindezeleka kwangaphakathi.
