Liboto tsa potoloho tse hatisitsoeng ke likarolo tse hlokahalang tsa lisebelisoa tse ngata tsa motlakase.Li-PCB tsa kajeno li na le likarolo tse 'maloa ho tsona: substrate, traces, solder mask, le silkscreen.E 'ngoe ea lisebelisoa tsa bohlokoa ka ho fetisisa ho PCB ke koporo, 'me ho na le mabaka a mangata a hore na ke hobane'ng ha koporo e sebelisoa ho e-na le lisebelisoa tse ling tse kang aluminium kapa tin.
Li-PCB li entsoe ka eng?
Ho boleloa ke k'hamphani ea kopano ea PCB, li-PCB li entsoe ka ntho e bitsoang substrate, e entsoeng ka fiberglass e matlafalitsoeng ka epoxy resin.Ka holim'a substrate ke lera la foil ea koporo e ka kopanngoang mahlakoreng ka bobeli kapa e le 'ngoe feela.Hang ha substrate e entsoe, bahlahisi ba beha likarolo ho eona.Ba sebelisa mask a solder le silkscreen hammoho le resistors, capacitor, transistors, diode, li-circuit chips, le likarolo tse ling tse ikhethang haholo.
Hobaneng ha Foil ea Copper e sebelisoa ho li-PCB?
Baetsi ba PCB ba sebelisa koporo hobane e na le conductivity e phahameng ea motlakase le ea mocheso.Ha motlakase o ntse o tsamaea le PCB, koporo e boloka mocheso o se ke oa senya le ho hatella karolo e setseng ea PCB.Ka li-alloys tse ling - joalo ka aluminium kapa thini - PCB e ne e ka futhumatsa ka mokhoa o sa lekanang 'me ea se sebetse hantle.
Koporo ke motsoako o ratoang hobane o ka romela matšoao a motlakase ho pholletsa le boto ntle le mathata leha e le afe a ho lahleheloa kapa ho fokotsa motlakase.Ho sebetsa hantle ha mocheso oa mocheso ho lumella bahlahisi hore ba kenye lisebelisoa tsa khale tsa mocheso holim'a metsi.Koporo ka boeona e sebetsa hantle, kaha ounce ea koporo e ka koahela lisekoere tsa maoto a lisekoere tsa substrate ea PCB ho 1.4 thousandths ea inch kapa 35 micrometers e teteaneng.
Koporo e sebetsa haholo hobane e na le elektronike e sa lefelloeng e ka tsamaeang ho tloha athomo e 'ngoe ho ea ho e' ngoe ntle le ho lieha.Hobane e lula e sebetsa hantle boemong boo bo tšesaane haholo joalo ka ha e sebetsa maemong a teteaneng, koporo e nyane e ea hole haholo.
Koporo le Litšepe Tse Ling Tsa Bohlokoa Tse Sebelisitsoeng Li-PCB
Batho ba bangata ba hlokomela hore li-PCB li tala.Empa, hangata li na le mebala e meraro karolong e ka ntle: khauta, silevera le khubelu.Ba boetse ba na le koporo e hloekileng ka hare le ka ntle ho PCB.Litšepe tse ling botong ea potoloho li hlaha ka mebala e fapaneng.Lera la khauta le theko e boima ka ho fetisisa, lesela la silevera le na le theko ea bobeli-e phahameng ka ho fetisisa, 'me le khubelu ke lera le theko e tlaase ka ho fetisisa.
Ho Sebelisa Khauta ea ho Koaheloa ka har'a li-PCB
koporo holim'a boto ea potoloho e hatisitsoeng
Lera le entsoeng ka khauta le sebelisoa bakeng sa shrapnel ea sehokelo le likaroloana tsa likarolo.Lera la khauta le qoelisoang le teng ho thibela ho falla ha liathomo tse holim'a metsi.Lera ha se khauta feela ka 'mala, empa le entsoe ka khauta ea sebele.Khauta e tšesaane ka mokhoa o makatsang empa e lekane ho lelefatsa nako ea bophelo ea likarolo tse hlokang ho rekisoa.Khauta e thibela likarolo tsa solder hore li se ke tsa senyeha ha nako e ntse e ea.
Ho Sebelisa Silver ea ho Koebetsoa ka har'a li-PCB
Silver ke tšepe e 'ngoe e sebelisoang ho etsa PCB.E theko e tlase haholo ho feta ho qoelisoa ka khauta.Ho qoelisoa ka silevera ho ka sebelisoa sebakeng sa ho qoelisoa ka khauta hobane ho boetse ho thusa ka khokahanyo, 'me ho fokotsa litšenyehelo tse akaretsang tsa boto.Hangata ho qoelisoa ka silevera ho sebelisoa ho li-PCB tse sebelisoang likoloing le lisebelisoa tsa k'homphieutha.
Copper Clad Laminate ka PCBs
Ho e-na le ho qoelisoa, koporo e sebelisoa e le seaparo sa seaparo.Ena ke lera le lefubelu la PCB, 'me ke tšepe e sebelisoang haholo.PCB e entsoe ka koporo e le tšepe ea motheo, 'me ho hlokahala hore lipotoloho li kopane le ho buisana ka katleho.
Foil ea koporo e sebelisoa joang ho li-PCB?
Koporo e na le ts'ebeliso e 'maloa ho li-PCB, ho tloha ho laminate ea koporo ho isa mesaletsa.Koporo e bohlokoa hore li-PCB li sebetse ka nepo.
PCB Trace ke eng?
Tsela ea PCB ke hore na e utloahala joang, tsela eo potoloho e lokelang ho e latela.Mehlala e kenyelletsa marang-rang a koporo, lithapo le li-insulation, hammoho le li-fuse le likarolo tse sebelisoang botong.
Tsela e bonolo ka ho fetisisa ea ho utloisisa mohlala ke ho nahana ka eona e le tsela kapa borokho.Bakeng sa ho amohela likoloi, lesela le lokela ho ba le bophara bo lekaneng ho tšoara bonyane tse peli tsa tsona.E hloka ho ba motenya ka ho lekaneng hore e se ke ea oa tlas'a khatello.Li boetse li hloka ho etsoa ka thepa e tla mamella boima ba likoloi tse tsamaeang ka eona.Empa, mesaletsa e etsa tsena tsohle ka tekanyo e nyane haholo ho tsamaisa motlakase ho fapana le likoloi.
Likarolo tsa likarolo tsa PCB Trace
Ho na le likarolo tse 'maloa tse etsang mohlala oa PCB.Ba na le mesebetsi e fapaneng e lokelang ho etsoa hore boto e etse mosebetsi oa eona ka mokhoa o lekaneng.Koporo e lokela ho sebelisoa ho thusa mesaletsa ho etsa mesebetsi ea eona, 'me ntle le PCB, re ne re ke ke ra ba le lisebelisoa tsa motlakase.Nahana ka lefatše le se nang li-smartphone, lilaptop, baetsi ba kofi le likoloi.Ke seo re ka bang le sona haeba li-PCB li ne li sa sebelise koporo.
PCB Trace Botenya
Moralo oa PCB o ipapisitse le botenya ba boto.Botenya bo tla ama ho leka-lekana 'me bo tla boloka likarolo tse amanang.

Mokhoa oa ho etsa li-PCB
Mokhoa oa ho etsa PCB o tšoana.Lik'hamphani tse ling li e etsa kapele ho feta tse ling, empa kaofela li sebelisa mokhoa o tšoanang le thepa.Mehato ke ena:
Etsa motheo ka fiberglass le resin
Beha likarolo tsa koporo holim'a motheo
Khetholla le ho beha mekhoa ea koporo
Hlatsoa boto ka bateng
Kenya mask a solder ho sireletsa PCB
Kenya silika ho PCB
Beha le ho rekisa li-resistors, li-circuits tse kopaneng, li-capacitor, le likarolo tse ling
Lekola PCB
Li-PCB li hloka ho ba le likarolo tse khethehileng haholo hore li sebetse hantle.E 'ngoe ea likarolo tsa bohlokoa ka ho fetisisa tsa PCB ke koporo.Alloy ena ea hlokahala ho tsamaisa motlakase ho lisebelisoa tseo li-PCB li tla kenngoa ho tsona.Ntle le koporo, lisebelisoa li ke ke tsa sebetsa hobane motlakase o ke ke oa ba le alloy ho feta.
