Mokhoa oa ho Etsa Li-PCB tsa Boleng bo Holimo? Tataiso e Felletseng ea Mehato ea Bohlokoa ea Tlhahiso ea Li-PCB
Mokhoa oa Tlhahiso ea PCB
Mohato oa 1: Netefatso ea Lintlha
Pele ho tlhahiso, moetsi oa PCB o netefatsa lintlha tsa ho etsa boto tse fanoeng ke moreki, ho kenyeletsoa boholo ba boto, litlhoko tsa ts'ebetso le bongata ba sehlahisoa. Tlhahiso e tsoela pele feela ka mor'a ho fihlela tumellano le moreki.
Mohato oa 2: Ho Seha Lintho Tse Boleloang
Ho ya ka tlhahisoleseding ya moreki ya ho etsa boto, seha diboto tsa tlhahiso ka dikotwana tse nyane tse fihlelang ditlhoko. Mesebetsi e ikgethang: thepa ya poleiti e kgolo → ho seha ho ya ka ditlhoko tsa MI → ho seha poleiti → ho seha/ho sila ka lehlakoreng le leng → ho ntsha poleiti.
Mohato oa 3: Ho cheka
Cheka bophara ba lesoba le hlokahalang maemong a tsamaellanang le lona botong ea PCB. Mesebetsi e ikhethileng: thepa ea poleiti e kholo → ho seha ho latela litlhoko tsa MI → ho phekola → ho seha/ho sila ha sekhutlo → ho ntša poleiti.
Mohato oa 4: Ho Teba Koporo
Lera le lesesaane la koporo le kenngwa ka dikhemikhale lesobeng la ho thibela mocheso. Mesebetsi e ikgethang: ho sila ka thata → ho leketlisa boto → mohala wa ho teba wa koporo ka boiketsetso → ho theola boto → ho inela ka hara 1% H2SO4 e hlapollotsweng → ho tebisa koporo.
Mohato oa 5: Phetisetso ea Litšoantšo
Fetisetsa litšoantšo ho tloha filiming ea tlhahiso ho ea botong. Mesebetsi e ikhethileng: boto ea hemp → ho tobetsa filimi → ho ema → ho otlolla → ho pepesehela → ho ema → nts'etsopele → tlhahlobo.
Mohato oa 6: Sekoahelo sa Litšoantšo
Electroplate lera la koporo la botenya bo hlokahalang le lera la khauta la nickel kapa tin holim'a letlapa la koporo le pepesitsoeng kapa lebota la lesoba la paterone ea potoloho. Mesebetsi e ikhethileng: poleiti e ka holimo → ho tlosa mafura → ho hlatsoa ka metsi a bobeli → ho bola ha micro → ho hlatsoa ka metsi → ho hlatsoa ka asiti → ho penta ka koporo → ho hlatsoa ka metsi → ho kolobisa asiti → ho penta ka tin → ho hlatsoa ka metsi → poleiti e ka tlase.
Mohato oa 7: Ho Tlosa Filimi
Tlosa lera la ho koahela le thibelang motlakase ka tharollo ea NaOH ho pepesa lera la koporo le seng la potoloho.
Mohato oa 8: Ho hlaba
Tlosa likarolo tse sa tsamaiseng potoloho ka reagent ea lik'hemik'hale.
Mohato oa 9: Maske ea Solder
Fetisetsa litšoantšo tsa filimi e tala botong, haholo-holo ho sireletsa potoloho le ho thibela ho kopanngoa ha likarolo tse nang le thini potolohong.
Mohato oa 10: Silkscreen
Printa litlhaku tse tsebahalang boto ea PCB. Ts'ebetso e ikhethileng: kamora ho lokisa maske ea solder ka ho qetela, e pholise 'me u eme u sa sisinyehe, lokisa skrine, u printe litlhaku, 'me qetellong u li folise.
Mohato oa 11: Menoana ea Khauta
Tlotsa lera la nickel/gold la botenya bo hlokahalang monoaneng oa polaka ho ntlafatsa ho tiea ha lona le ho hanyetsa ho tsofala ha lona.
Mohato oa 12: Ho theha
Thunya sebopeho se hlokoang ke moreki o sebelisa hlobo kapa mochini oa CNC.
Mohato oa 13: Teko
Liphoso tse sebetsang tse bakoang ke lipotoloho tse bulehileng, lipotoloho tse khutšoane, jj., li thata ho li lemoha ka tlhahlobo ea pono 'me li ka lekoa ka ho sebelisa teko ea probe e fofang.
