Kenyelletso ea lisebelisoa tsa FR4

FR ho FR4 e emela lelakabe la lelakabe, 'me palo ea 4 e khetholla thepa ho tsoa ho lisebelisoa tse ling tsa sehlopha sena.FR4 ke khalase ea fiber e matlafalitsoeng epoxy laminate e shebahalang joaloka lesela le tšesaane le lohiloeng.Lentsoe FR4 le boetse le emela sehlopha se sebelisoang ho etsa li-laminate tsena.Sebopeho sa fiberglass se fana ka botsitso ba sebopeho bakeng sa thepa.Fiber ea khalase e koahetsoe ke epoxy e thibelang mollo.Sena se fana ka nako e telele ea thepa le thepa e matla ea mechine.Likarolo tsena kaofela li etsa hore boto ea potoloho e hatisitsoeng ea FR4 e ratoe haholo har'a baetsi ba likonteraka tsa elektroniki.

Boto ea potoloho e hatisitsoeng ea FR4 le eona e tumme ka mabaka a latelang:

FR4 ke thepa e theko e tlase.

1, E na le matla a phahameng a dielectric, a tlatsetsang ts'ebetsong ea eona ea ho kenya motlakase.

2, Thepa e na le karo-karolelano e phahameng ea boima ba 'mele' me e bobebe ka boima.

3, Ha e na mongobo ebile e na le mocheso o lekanyelitsoeng.

4, thepa e na le thepa e ntle ea ho senya motlakase.

5, FR4 ha e monye metsi, ka hona e loketse mefuta eohle ea lits'ebetso tsa Marine PCB.

6, lisebelisoa li mosehla ho isa botala bo bobebe, li loketse ts'ebeliso efe kapa efe.Likarolo tsena kaofela li etsa hore e tšoanelehe bakeng sa libaka tse fapaneng.

FR4 e hlophisitsoe joang ka liboto tse tloaelehileng tse hatisitsoeng tsa FR4?FR4 e sebetsa e le motheo oa PCB efe kapa efe.Boitsebiso bo laminated ka foil ea koporo.Sebelisa mocheso le sekhomaretsi ho laminate.Foil ea koporo e ka sebelisoa ho laminate lintho tse tsoang mahlakoreng a le mong kapa ka bobeli.
