Uyini umehluko phakathi Ibhodi le-FR4 epoxy fiberglass futhi 3240 epoxy fiberglass board?

Ibhodi yasekhaya epoxy fiberglass ngokuvamile 3240, futhi Ibhodi le-FR4 epoxy fiberglass ngokuvamile ibhodi lokufakelwa kwamanye amazwe. Kodwa kokubili kuyizinto ezihluke kakhulu ezintweni ezibonakalayo noma izakhiwo zamakhemikhali. Ake ngithule kuwo wonke umuntu kafushane:

1, 3240 epoxy glass fiber board, igama eliphelele eliphelele: 3240 epoxy phenolic fiberglass cloth laminate. Isebenzisa i-epoxy resin glue kanye ne-phenolic material njenge-ejenti yokwelapha. Izinga lokushisa livamise ukuba ngu-155 degrees. Ukusebenza komshini okungcono. Ibuye ifaneleke kakhulu kuma-transformers namafutha e-transformer. Ukuminyana ngokuvamile aweqi izinga likazwelonke: 1.9.

Kodwa-ke, abakhiqizi abaningi basekhaya manje babamba iqhaza kuma-fillers, njenge-talcum powder, ukuze kugcinwe izindleko ohlelweni lokukhiqiza. Ukuminyana kwabo kuye kwanda kakhulu. Iphinde inciphise kakhulu ukusebenza kukagesi. Ifaneleka kuphela kumaphrojekthi wokufaka okuvamile.

2. FR4 epoxy glass fibre board. Kusetshenziswa i-epoxy glue. Kodwa akuyona i-ejenti yokwelapha enezinto ze-phenolic. Ukwelashwa ngokuphelele ekushiseni okuphezulu. Iqhathaniswa nepulasitiki ehlanzekile. Izinga lokushisa ngokuvamile lingaphezu kuka-180 degrees. Ukusebenza komshini kunamandla kakhulu. Uzakwethu wake wancokola wathi ukusika ngomshini wokusika kusika izinhlansi.

ibonisa ukusebenza kwayo kokucubungula. Futhi ngeke iqhekeke noma ihlukanise lapho isetshenziswa. Ukusebenza kukagesi kunamandla kakhulu. Ifaneleka kumabhodi wesifunda se-elekthronikhi kanye nama-laminates e-copper clad. Izinto eziyisisekelo nazo zingase zibe yindwangu ecolekile. Indwangu ye-fiber ye-elekthronikhi. Ngokuvamile kuba ukuminyana okungu-1.85. Imelana nokugqwala kwamakhemikhali.

3240 epoxy fiberglass board kanye ne-FR4 epoxy fiberglass board amabhodi amabili avame kakhulu e-epoxy fiberglass asemakethe njengamanje. Wonke umuntu uthi i-FR4 ingcono kuno-3240. Uyini umehluko phakathi kwabo?

Umehluko 1: i-FR4 inokusebenza okuhle kwelangabi okubuyisela emuva.

I-FR4 iwumkhiqizo othuthukisiwe we-3240 epoxy glass fiber board. Ukusebenza kwe-flame retardant ye-FR4 epoxy glass fiber board kuhlangabezana nezinga le-UL94V-0 likazwelonke. I-3240 epoxy glass fiber board ayinazo izinto ezivimbela ilangabi.

Umehluko 2: Umbala oguqukayo.

Umbala we-FR4 ungokwemvelo kakhulu, u-jade kancane, futhi umbala we-3240 epoxy fiberglass board uyacwayiza kancane. Akubukeki ngokwemvelo. Iningi lemibala alifani kakhulu.

Umehluko wesithathu: I-FR4 ayinayo imisebe futhi ihambisana nemvelo.

Ibhodi le-3240 epoxy glass fiber liqukethe i-halogen, elingahambisani neze nemvelo emvelweni kanye nomzimba womuntu. Futhi ayihambisani nesu lezwe lentuthuko eqhubekayo eqhubekayo. I-FR4 epoxy glass fiber board ihluke nje.

Umehluko 4: i-FR4 inokuqina okuhle kobukhulu.

I-FR4 inokuqina okungcono kwe-dimensional kuno-3240, futhi phakathi nenqubo yokucindezela, ukubekezelela ukushuba kwe-FR4 nakho kungcono kakhulu kuno-3240, okulungele kakhulu ukucutshungulwa.

Umehluko wesihlanu: I-FR4 ingazicisha umlilo.

I-FR4 ingacinywa ngokwemvelo uma kunomlilo.

umehluko wesithupha: ukumuncwa kwamanzi aphansi.

Ukumuncwa kwamanzi (D-24/23, ipuleti ukujiya 1.6mm): ≤19mg, enikeza usizo oluhle ekusetshenzisweni kwayo kuma-transformer emanzi nakwenye imishini.

Ngenxa yokuthi i-FR-4 epoxy glass fiber board inokusebenza okuhle kakhulu, manje isisetshenziswa njengempahla yokugqumisa izingxenye ezimbonini zikagesi neze-elekthronikhi. Vele, ibhodi ye-3240 epoxy fiberglass isenayo imakethe ethile ngenxa yenzuzo yayo yentengo.
