Boima ba Koporo bakeng sa Tlhahiso ea PCB: Tataiso ea Motheo

Liboto tsa potoloho tse hatisitsoeng (PCBs) ke karolo ea bohlokoa ea lisebelisoa tsa elektroniki tsa sejoale-joale. Li sebetsa e le mokokotlo oa lisebelisoa tsa elektronike, li fana ka sethala sa ho hokahanya ha likarolo tsa elektronike.Copper ke sekontiri se hloahloa sa motlakase 'me se sebelisoa haholo tlhahisong ea PCB.

Ts'ebetsong ea tlhahiso ea PCB, boima ba koporo bo phetha karolo ea bohlokoa.Boima ba koporo bo bolela botenya kapa palo ea koporo e sebelisoang holim'a boto ea potoloho. Boima ba koporo bo sebelisoang ha ho etsoa PCB bo ama ka kotloloho thepa ea motlakase le ea mochini ea boto. Ho blog ena, re tla hlahloba litekanyo tse fapaneng tsa koporo tse sebelisoang ho etsa PCB le bohlokoa ba tsona.

Ho utloisisa Boima ba Koporo ho PCB Manufacturing

Boima ba koporo hangata bo lekanngoa ka li-ounces ka leoto le leng le le leng (oz/ft²). Boima ba koporo bo sebelisoang haholo ha ho etsoa PCB bo tloha ho 0.5 oz/square foot (17 µm) ho isa ho 3 oz/square foot (105 µm). Boima bona bo lekanya botenya ba koporo ba likarolo tse ka ntle tsa PCB, likarolo tse ka hare, le masoba a koporo a koahetsoeng.

Khetho ea boima ba koporo e itšetlehile ka lintlha tse kang ts'ebetso e hlokahalang ea motlakase, matla a mochine le litšenyehelo. Ha re

shebisisa ka botebo litekanyo tse fapaneng tsa koporo le ts'ebeliso ea tsona ho tlhahiso ea PCB.

1. 0.5 oz/ft2 (17 µm) Boima ba koporo:
Ena ke boima bo bobebe ba koporo bo sebelisoang ho etsa PCB. E ka tloaelo ho sebelisoa e bonolo le e bobebe PCB ditshebediso tsa ka. Hangata mapolanka ana a sebelisoa ho lisebelisoa tsa elektronike tsa bareki moo litšenyehelo le boima ba tsona e leng lintlha tse kholo. Leha ho le joalo, botenya ba koporo bo fokotsehileng bo ama bokhoni ba ho jara maqhubu a phahameng 'me bo ka baka ho hanyetsa ho eketsehileng.

2. 1 oz/square foot (35 µm) boima ba koporo:
Ena ke boima ba koporo bo sebelisoang haholo ho etsa PCB. E hlahisa ho leka-lekana pakeng tsa ts'ebetso le ho boloka chelete. Li-PCB tse nang le 1 oz/sq. ft. boima ba koporo bo ka sebetsana le maqhubu a itekanetseng 'me bo loketse bakeng sa mefuta e sa tšoaneng ea lisebelisoa, ho akarelletsa le mehala ea puisano, likoloi le lisebelisoa tsa elektronike tsa indasteri.

3. 2 oz/square foot (70 µm) boima ba koporo:
Ha tlhokahalo ea bokhoni bo phahameng ba ho jara hona joale e ntse e eketseha, li-PCB tse nang le boima ba koporo ba li-ounces tse 2/square foot li ba tsa bohlokoa. Tse tsejoang ka mokhoa oa tsona o ntlafetseng oa ho futhumatsa mocheso, liboto tsena li atisa ho sebelisoa ho lisebelisoa tsa elektronike tse matla, li-amplifiers tse matla, litsamaiso tsa UPS le lisebelisoa tse ling tse hlokang matla a ho jara hona joale.

4. 3 oz/ft2 (105 µm) Boima ba koporo:
Li-PCB tse boima ba koporo ba li-ounces tse 3 ka leoto le leng le le leng li nkoa e le liboto tse boima tsa koporo. Liboto tsena li sebelisoa lits'ebetsong tse hlokang matla a maholo a hona joale a ho jara kapa ho fokotsa mocheso hantle. Mehlala e meng e kenyelletsa litsamaiso tsa kabo ea matla, lishaja tsa betri tsa hajoale, le lilaoli tsa makoloi.

Bohlokoa ba Boima ba Koporo ho PCB Manufacturing

Ho khetha boima bo nepahetseng ba koporo ho bohlokoa ho netefatsa ts'ebetso ea PCB le ho ts'epahala. Mona ke lintlha tse ling tsa bohlokoa tse totobatsang bohlokoa ba boima ba koporo:

1. Ts'ebetso ea motlakase:
Boima ba koporo bo etsa qeto ea bokhoni ba PCB ba ho jara hona joale ntle le ho theha khanyetso e feteletseng. Botenya bo sa lekaneng ba koporo bo ka baka ho hanyetsa ho phahama, ho fella ka ho theoha ha motlakase le ho futhumala ha boto. Ka lehlakoreng le leng, boima bo phahameng ba koporo bo lumella ho sebetsana hantle le hona joale le ho hanyetsa ho tlaase.

2. Matla a mochine:
Ntle le ho tsamaisa motlakase, koporo e boetse e fana ka matlafatso ea mochini ho PCB. Boima bo nepahetseng ba koporo bo eketsa matla le ho tšoarella ho boto ea potoloho, ho e lumella ho hanela ho kobeha, ho phunya, kapa khatello e 'ngoe ea' mele.

3. Taolo ea mocheso:
Koporo ke conductor e babatsehang ea mocheso. Boima bo lekaneng ba koporo bo thusa ho senya mocheso o hlahisoang ke likarolo tse behiloeng ho PCB. Sena se thibela khatello ea mocheso kapa ho hlōleha ha karolo ka lebaka la ho chesa haholo, ho netefatsa nako e telele le ho tšepahala ha boto.

4. Lekola bophara le litataiso tsa sebaka:
Boima ba koporo bo ama bophara ba sekhahla le litataiso tsa sebaka nakong ea moralo le moralo oa PCB. Boima bo phahameng ba koporo bo hloka bophara bo pharaletseng le sebaka sa sebaka ho lumella ho phalla hantle hona joale le ho qoba ho phahama ho feteletseng ha mocheso.

Ha re phethela

Ka kakaretso,ho khetha boima bo nepahetseng ba koporo ho bohlokoa ho theha PCB e sebetsang hantle le e tšepahalang.Khetho e itšetlehile ka litlhoko tse khethehileng tsa kopo, ho nahanela ts'ebetso ea motlakase, matla a mochine le litlhoko tsa tsamaiso ea mocheso. Ebang ke lisebelisoa tsa elektronike tse bobebe kapa lisebelisoa tse matla tsa indasteri, boima ba koporo bo phetha karolo ea bohlokoa tlhahisong ea PCB 'me bo lokela ho nahanoa ka hloko nakong ea moralo.
