Ungawakha Kanjani Ama-PCB Asezingeni Eliphezulu? Umhlahlandlela Ophelele Wezinyathelo Ezibalulekile Zokukhiqiza Ama-PCB
Inqubo Yokukhiqiza ye-PCB
Isinyathelo 1: Ukuqinisekiswa Kwedatha
Ngaphambi kokukhiqiza, umenzi we-PCB uqinisekisa idatha yokwenza ibhodi enikezwe yikhasimende, okuhlanganisa usayizi webhodi, izidingo zenqubo, kanye nobuningi bomkhiqizo. Ukukhiqiza kuqhubeka kuphela ngemva kokufinyelela esivumelwaneni nekhasimende.
Isinyathelo 2: Ukusika Izinto
Ngokusho kolwazi lokwakha ibhodi lekhasimende, sika amabhodi okukhiqiza abe yizicucu ezincane ezihlangabezana nezidingo. Imisebenzi ethile: izinto zepuleti elikhulu → ukusika ngokwezidingo ze-MI → ukusika ipuleti → ukusika/ukugaya ekhoneni/ukukhipha ipuleti.
Isinyathelo 3: Ukubhoboza
Bopha ububanzi bembobo obudingekayo ezindaweni ezifanele ebhodini le-PCB. Imisebenzi ethile: izinto zepuleti elikhulu → ukusika ngokwezidingo ze-MI → ukwelapha → ukusika ekhoneni/ukugaya umphetho → ukukhipha ipuleti.
Isinyathelo 4: Ukucwila Kwethusi
Ungqimba oluncane lwethusi lufakwa ngamakhemikhali emgodini wokuvikela. Imisebenzi ethile: ukugaya okungafanele → ukulengisa ibhodi → umugqa wokucwilisa wethusi ozenzakalelayo → ukwehlisa ibhodi → ukucwilisa ku-1% H2SO4 encibilikisiwe → ukwenza ithusi libe likhulu.
Isinyathelo 5: Ukudluliswa Kwesithombe
Dlulisa izithombe kusuka kufilimu yokukhiqiza ziye ebhodini. Imisebenzi ethile: ibhodi le-hemp → ukucindezela ifilimu → ukuma → ukuqondanisa → ukuvezwa → ukuma → ukuthuthukiswa → ukuhlolwa.
Isinyathelo 6: Ukufakwa Kwezithombe
Faka i-electroplate ungqimba lwethusi olunobukhulu obudingekayo kanye nongqimba lwegolide lwe-nickel noma lwe-tin odongeni lwethusi oluveziwe noma umgodi wephethini yesekethe. Imisebenzi ethile: ipuleti eliphezulu → ukususa amafutha → ukugeza ngamanzi okwesibili → ukugqwala okuncane → ukugeza ngamanzi → ukugeza nge-asidi → ukubopha ngethusi → ukugeza ngamanzi → ukucwilisa nge-asidi → ukubopha ngethini → ukugeza ngamanzi → ipuleti elingezansi.
Isinyathelo 7: Ukususwa Kwefilimu
Susa ungqimba lokumboza oluvimbela i-electroplating ngesisombululo se-NaOH ukuze uveze ungqimba lwethusi olungeyona isekethe.
Isinyathelo 8: Ukuqopha
Susa izingxenye ezingezona ezesekethe nge-reagent yamakhemikhali.
Isinyathelo 9: Imaski Yokusondeza
Dlulisa izithombe zefilimu eluhlaza ebhodini, ikakhulukazi ukuvikela isekethe nokuvimbela ukunamathela kwezingxenye ngethini kusekethe.
Isinyathelo 10: Isikrini se-Silkscreen
Phrinta izinhlamvu ezibonakalayo ebhodini le-PCB. Imisebenzi ethile: ngemva kokulungiswa kokugcina kwemaski ye-solder, pholile bese ume, lungisa isikrini, phrinta izinhlamvu, bese ekugcineni ulungisa.
Isinyathelo 11: Iminwe Yegolide
Faka ungqimba lwe-nickel/gold olunobukhulu obudingekayo emunweni we-plug ukuze uthuthukise ubulukhuni balo kanye nokumelana nokuguguleka.
Isinyathelo 12: Ukwakha
Shaya isimo esidingwa yikhasimende usebenzisa isikhunta noma umshini we-CNC.
Isinyathelo 13: Ukuhlola
Amaphutha okusebenza abangelwa amasekethe avulekile, amasekethe amafushane, njll., kunzima ukuwabona ngokuhlola okubonakalayo futhi angahlolwa kusetshenziswa umhloli we-flying probe.
