Rogers Pcb e entsoe joang?

Rogers PCB, eo hape e tsejoang ka hore ke Rogers Printed Circuit Board, e tumme haholo ebile e sebelisoa liindastering tse fapaneng ka lebaka la ts'ebetso ea eona e holimo le ts'epo. Li-PCB tsena li entsoe ka thepa e khethehileng e bitsoang Rogers laminate, e nang le lisebelisoa tse ikhethang tsa motlakase le tsa mochini. Ka poso ena ea blog, re tla ikakhela ka setotsoana ho tse rarahaneng tsa tlhahiso ea Rogers PCB, re hlahloba lits'ebetso, lisebelisoa le lintlha tse amehang.

Ho utloisisa ts'ebetso ea tlhahiso ea Rogers PCB, re tlameha ho qala ho utloisisa hore na liboto tsena ke eng le ho utloisisa hore na Rogers laminates e bolela eng.Li-PCB ke likarolo tsa bohlokoa tsa lisebelisoa tsa elektroniki, tse fanang ka meaho ea tšehetso ea mochini le likhokahano tsa motlakase. Li-PCB tsa Rogers li batloa haholo lits'ebetsong tse hlokang phetisetso ea matshwao a maqhubu a phahameng, tahlehelo e tlase le botsitso. Li sebelisoa haholo liindastering tse kang tsa mehala ea puisano, sefofane, bongaka le likoloi.

Rogers Corporation, mofani oa litharollo tsa thepa e tsebahalang, e ntlafalitse Rogers laminate ka ho khetheha bakeng sa ho sebelisoa ho etsa liboto tsa potoloho tse sebetsang hantle haholo. Rogers laminate ke thepa e kopantsoeng e nang le lesela la fiberglass le tlatsitsoeng ka ceramic le sisteme ea resin ea hydrocarbon thermoset. Motsoako ona o bonts'a lisebelisoa tse ntle tsa motlakase joalo ka tahlehelo e tlase ea dielectric, conductivity e phahameng ea mocheso le botsitso bo botle ba sebopeho.

Joale, ha re ke re hlahlobeng ts'ebetso ea tlhahiso ea Rogers PCB:

1. Moralo oa moralo:

Mohato oa pele oa ho etsa PCB efe kapa efe, ho kenyelletsa le Rogers PCBs, e kenyelletsa ho rala moralo oa potoloho. Baenjiniere ba sebelisa software e khethehileng ho theha schematics ea liboto tsa potoloho, ho beha le ho hokahanya likarolo ka nepo. Mokhahlelo ona oa pele oa moralo o bohlokoa bakeng sa ho khetholla ts'ebetso, ts'ebetso, le ts'epahalo ea sehlahisoa sa ho qetela.

2. Khetho ea lintho tse bonahalang:

Hang ha moralo o phethiloe, khetho ea thepa e ba ea bohlokoa. Rogers PCB e hloka ho khetha thepa e nepahetseng ea laminate, ho nahanela lintlha tse kang tse hlokahalang dielectric constant, dissipation factor, thermal conductivity, and mechanical properties. Li-laminate tsa Rogers li fumaneha ka mefuta e fapaneng ea limaraka ho fihlela litlhoko tse fapaneng tsa kopo.

3. Khaola laminate:

Ha moralo le khetho ea thepa e phethiloe, mohato o latelang ke ho khaola laminate ea Rogers ka boholo. Sena se ka finyelloa ho sebelisoa lisebelisoa tse khethehileng tsa ho itšeha joalo ka mechini ea CNC, ho netefatsa litekanyo tse nepahetseng le ho qoba tšenyo leha e le efe ea thepa.

4. Ho cheka le ho tšela koporo:

Nakong ena, likoti li kenngoa ka har'a laminate ho latela moralo oa potoloho. Likoti tsena, tse bitsoang vias, li fana ka likhokahano tsa motlakase lipakeng tsa likarolo tse fapaneng tsa PCB. Likoti tse phuntsoeng li kenngoa koporo ho theha conductivity le ho ntlafatsa botšepehi ba sebopeho sa vias.

5. Litšoantšo tsa potoloho:

Ka mor'a ho cheka, lera la koporo le sebelisoa ho laminate ho etsa litsela tsa conductive tse hlokahalang bakeng sa ts'ebetso ea PCB. Boto e entsoeng ka koporo e koahetsoe ka thepa e sa utloeng khanya e bitsoang photoresist. Sebopeho sa potoloho se fetisetsoa ho photoresist ho sebelisa mekhoa e khethehileng e kang photolithography kapa imaging e tobileng.

6. Etching:

Ka mor'a hore moralo oa potoloho o hatisoe ho photoresist, ho sebelisoa etchant ea lik'hemik'hale ho tlosa koporo e feteletseng. Etchant e qhaqha koporo e sa batleheng, e siea ka morao mokhoa o lakatsehang oa potoloho. Ts'ebetso ena e bohlokoa ho theha mesaletsa ea conductive e hlokahalang bakeng sa likhokahano tsa motlakase tsa PCB.

7. Ho tsamaisana le lera le lamination:

Bakeng sa li-PCB tsa Rogers tse nang le mefuta e mengata, likarolo tsa motho ka mong li tsamaellana hantle ho sebelisoa lisebelisoa tse khethehileng. Likarolo tsena li phuthetsoe le ho etsoa laminated hammoho ho etsa sebopeho se momahaneng. Mocheso le khatello li sebelisoa 'meleng le ka motlakase ho tlama lihlopha, ho netefatsa hore ho na le conductivity pakeng tsa bona.

8. Electroplating le kalafo ea holim'a metsi:

Ho sireletsa potoloho le ho netefatsa ts'epahalo ea nako e telele, PCB e kena ts'ebetsong ea plating le holim'a metsi. Lera le lesesaane la tšepe (hangata la khauta kapa thini) le manehiloe holim'a bokaholimo ba koporo. Ho roala hona ho thibela kutu 'me ho fana ka sebaka se setle bakeng sa likarolo tsa soldering.

9. Sesebelisoa sa maske sa solder le skrine ea silika:

Sebaka sa PCB se koahetsoe ka mask a solder (hangata a matala), a siea feela libaka tse hlokahalang bakeng sa likhokahano tsa likarolo. Lera lena le sireletsang le sireletsa mesaletsa ea koporo ho tsoa linthong tsa tikoloho joalo ka mongobo, lerōle le ho kopana ka phoso. Ho feta moo, lilai tsa sekirini sa silika li ka eketsoa ho tšoaea moralo oa likarolo, baqapi ba lireferense le lintlha tse ling tsa bohlokoa holim'a PCB.

10. Teko le Taolo ea Boleng:

Hang ha ts'ebetso ea tlhahiso e phethiloe, ho etsoa tlhahlobo e phethahetseng le lenaneo la tlhahlobo ho netefatsa hore PCB e sebetsa ebile e kopana le litlhaloso tsa moralo. Liteko tse fapaneng tse kang tlhahlobo ea ho tsoela pele, tlhahlobo ea motlakase o phahameng le tlhahlobo ea impedance li netefatsa bots'epehi le ts'ebetso ea li-PCB tsa Rogers.

Ka kakaretso

Ho etsoa ha li-PCB tsa Rogers ho kenyelletsa ts'ebetso e hlokolosi e kenyelletsang moralo le moralo, khetho ea thepa, ho seha li-laminate, ho cheka le ho tšela koporo, ho nahana ka potoloho, ho hlopha, ho lokisoa ha lera le lamination, plating, ho lokisa holim'a sefahleho, maske a solder le lits'ebetso tsa khatiso tsa skrineng hammoho le lits'ebetso tse felletseng. teko le taolo ya boleng. Ho utloisisa lintho tse rarahaneng tsa tlhahiso ea Rogers PCB ho totobatsa tlhokomelo, ho nepahala, le botsebi bo amehang ho etsa liboto tsena tse sebetsang hantle.
