PCB ea koporo e boima ke eng?
Sehlopha sena sa PCB ke khetho ea pele ha maqhubu a phahameng a ke ke a qojoa: PCB ea koporo e teteaneng , e entsoeng ka theknoloji ea sebele ea etching. Li-PCB tse teteaneng tsa koporo li khetholloa ka meaho e nang le botenya ba koporo ho tloha ho 105 ho isa ho 400 µm. Li-PCB tsena li sebelisoa bakeng sa liphetho tse kholo (tse phahameng) tsa hajoale le ho ntlafatsa taolo ea mocheso. Koporo e teteaneng e lumella likarolo tse kholo tsa PCB-cross-sections bakeng sa meroalo e phahameng ea hona joale 'me e khothalletsa ho senya mocheso. Meetso e tloaelehileng haholo ke ea multilayer kapa mahlakore a mabeli.
Le hoja ho se na tlhaloso e tloaelehileng ea Koporo e Boima, ka kakaretso e amoheloa hore haeba 3 ounces (oz) ea koporo kapa ho feta e sebelisoa likarolong tse ka hare le tse ka ntle tsa boto ea potoloho e hatisitsoeng, e bitsoa PCB e boima ea koporo . Potoloho efe kapa efe e nang le botenya ba koporo bo fetang 4 oz ka leoto la lisekoere (ft2) le eona e arotsoe joalo ka PCB e boima ea koporo. Koporo e feteletseng e bolela 20 oz ka ft2 ho isa ho 200 oz ka ft2.
PCB e boima ea koporo e khetholloa e le PCB e nang le botenya ba koporo ba 3 oz ka ft2 ho isa ho 10 oz ka ft2 ka likarolo tse ka ntle le tse ka hare. PCB e boima ea koporo e hlahisoa ka boima ba koporo ho tloha ho 4 oz ka ft2 ho isa ho 20 oz ka ft2. Boima ba koporo bo ntlafetseng, hammoho le plating e teteaneng le substrate e loketseng ka har'a likoti li ka fetola boto e fokolang hore e be sethaleng sa nako e telele le se ka tšeptjoang sa wiring. Li-conductor tse boima tsa koporo li ka eketsa botenya bohle ba PCB haholo. Botenya ba koporo bo lokela ho nkoa kamehla nakong ea sethaleng sa moralo oa potoloho. Bokhoni ba ho jara hona joale bo khethoa ho tloha bophara le botenya ba koporo e boima.
Molemo o ka sehloohong oa liboto tse boima tsa koporo ke bokhoni ba bona ba ho pholoha khafetsa ho pepeseha ho feteletseng hona joale, mocheso o phahameng le ho palama libaesekele tse chesang khafetsa, tse ka senyang boto ea potoloho e tloaelehileng ka metsotsoana. Boto e boima ea koporo e na le bokhoni bo phahameng ba ho mamellana, e leng se etsang hore e lumellane le likopo maemong a thata a kang, lihlahisoa tsa indasteri ea tšireletso le ea sefofane.
E meng ea melemo e ekelitsoeng ea liboto tse boima tsa koporo ke:
Boholo ba sehlahisoa se kopaneng ka lebaka la boima ba 'maloa ba koporo moalo o le mong oa potoloho
Litsela tse boima tsa koporo li fetisa matla a holimo ka har'a PCB le ho thusa ho fetisetsa mocheso ho siling e ka ntle ea mocheso.
Phapang pakeng tsa Standard PCB le Thick Copper PCB
Li-PCB tse tloaelehileng li ka hlahisoa ka mekhoa ea ho roala koporo le ho betla. Li-PCB tsena li pentiloe ho eketsa botenya ba koporo ho lifofane, mesaletsa, li-PTH le liphaephe. Palo ea koporo e sebelisitsoeng ha ho etsoa li-PCB tse tloaelehileng ke 1oz. Ha ho etsoa PCB ea koporo e boima, palo ea koporo e sebelisoang e kholo ho feta 3oz.
Bakeng sa mapolanka a tloaelehileng a potoloho, ho sebelisoa mekhoa ea ho roala koporo le ho pata. Leha ho le joalo, li-PCB tse boima tsa koporo li hlahisoa ka mokhoa o fapaneng oa ho kopanya le ho betla mehato. Li-PCB tse tloaelehileng li etsa mesebetsi e bobebe ha liboto tse boima tsa koporo li etsa mesebetsi e boima.
Li-PCB tse tloaelehileng li tsamaisa hona joale ka tlase ha li-PCB tse boima tsa koporo li tsamaisa hona joale. Li-PCB tsa koporo tse teteaneng li loketse lits'ebetso tsa maemo a holimo ka lebaka la kabo ea tsona e sebetsang hantle ea mocheso. Li-PCB tsa koporo tse boima li na le matla a betere a mochini ho feta li-PCB tse tloaelehileng. Liboto tse boima tsa koporo li ntlafatsa bokhoni ba boto eo li sebelisoang ho eona.

Boima ba koporo: Ena ke tšobotsi e ka sehloohong e khethollang li-PCB tse boima tsa koporo. Boima ba koporo bo bolela boima ba koporo e sebelisoang sebakeng sa maoto a lisekoere. Boima bona hangata bo lekanngoa ka li-ounces. E bontša botenya ba koporo holim'a lera.
Likarolo tse ka ntle: Tsena li bua ka likarolo tsa koporo tse kantle tsa boto. Likarolo tsa elektronike hangata li kopantsoe le likarolo tse ka ntle. Likarolo tse ka ntle li qala ka foil ea koporo e koahetsoeng ka koporo. Sena se thusa ho eketsa botenya. Boima ba koporo ba likarolo tse ka ntle bo behiloe esale pele bakeng sa meralo e tloaelehileng. Moetsi oa PCB o boima oa koporo o ka fetola boima le botenya ba koporo ho lumellana le tlhoko ea hau.
Likarolo tse ka hare: Botenya ba dielectric, hammoho le boima ba koporo ba likarolo tse ka hare, bo hlalositsoe esale pele bakeng sa merero e tloaelehileng. Leha ho le joalo, boima ba koporo le botenya ka likarolo tsena li ka fetoloa ho latela litlhoko tsa hau.
Li-PCB tse boima tsa koporo li sebelisetsoa merero e mengata e kang li-transformer tse planar, ho senya mocheso, ho fana ka matla a phahameng, li-converter tsa matla, joalo-joalo Ho na le tlhokahalo e ntseng e eketseha ea mapolanka a boima a koporo lik'homphieutha, likoloi, sesole le taolo ea indasteri.
Liboto tsa potoloho tse hatisitsoeng tsa koporo e boima li boetse li sebelisoa ho:
Lisebelisoa tsa motlakase, li-converter tsa motlakase
