Ingabe uyazi ukuthi umsebenzi we PCB ibhodi  kunomsele Isixazululo? Injongo eyinhloko kokulawulwa isixazululo PCB Plating iwukugcina konke yizici zamakhemikhali ngaphakathi kobubanzi eshiwo inqubo. I izakhiwo wamakhemikhali nezibulala ezingokomzimba enamathela kuthiwa kuqinisekiswe kuphela ngaphakathi kwemigomo ebekiwe kule nqubo. Kunezinhlobo eziningi izinqubo esetshenziswa ukulawula, kuhlanganise amakhemikhali zihlukaniswa, ukuhlolwa ngokomzimba, acid ukubaluleka ukuzimisela izixazululo, amandla adonsela phansi ethize solution noma ukuzimisela colorimetric. Lezi zinqubo zenzelwe ukuqinisekisa ukunemba, ukungaguquguquki nokuzinza nemingcele okugeza. Kukhethwa ukulawula indlela kunqunywa uhlobo ukugcwala kwamanzi.

Nakuba indlela kohlaziyo lithembeke ukulawula okugeza, asikho isiqinisekiso sokuthi enamathela ezinhle izotholwa. Ngakho-ke, futhi kuyadingeka ukuze iphendukele Electroplating ukuhlolwa. Ikakhulukazi, abaningi Electroplating zokugeza engeza izithasiselo organic ngcono isimo kanye nokusebenza enamathela ukuze kuqinisekiswe izakhiwo ezinhle kagesi kanye mechanical luthi alufane. Lezi izithasiselo kunzima ukusebenzisa izindlela amakhemikhali ukuhlaziywa, futhi sikuhlaziye kuqhathaniswa usebenzisa izindlela Electroplating test, okuyinto abakhonza luyasiza kubalulekile ukulawula Ukwakheka kwamakhemikhali kubhavu. Izilawuli engeziwe zihlanganisa ukuzimisela amazinga okufakiwe kanye izinguquko, filtration kanye ukuhlanzwa. Lezi kudingeka kube ngokucophelela "sathi:" kusukela Holstein Plating okugeza test iphaneli, futhi yabe isihlaziywa, sikuhlaziye yekhalenda kusuka isimo ipuleti enamathela ukusatshalaliswa ukufeza ngcono noma ukuthuthukiswa inqubo. Isinyathelo injongo.

Ngokwesibonelo, kwemigomo dispersibility okusezingeni eliphezulu, elikhanyayo okusezingeni eliphezulu acid ongaphakeme zethusi Plating okugeza kuyalungiswa by indlela chemical ukusonga; ngaphezu ahlukahlukene okuhlaziya amakhemikhali, ikhambi yethusi kwamakhemikhali ngaphansi pH acid value noma i-ratio futhi Color ukumeda njll Uma ukwakheka kwamakhemikhali ngaphakathi inqubo ububanzi ngemva ukuhlaziywa, kubalulekile ukuba banake enkulu izinguquko nemingcele futhi isimo kobuso substrate ukuba kuhlinzwa, ezifana nezinga lokushisa elizosetshenziswa kule isixazululo Plating, kwabantu kwamanje, indlela obandayo futhi ithonya isimo ukwelashwa ebusweni substrate phezu okugeza. Ikakhulukazi, kubalulekile ukulawula wezinto okuphothula-zinc of esikhanyayo acid isixazululo zethusi Plating, eyeqa ovumelekile inqubo sebhithi value, futhi ngqo kuthinta isimo kobuso ungqimba zethusi; ithini-lead isixazululo ingxubevange okugeza kumele ngokuqinile ukulawula okuqukethwe ukungcola ithusi, ezifana ethile sizothinta wettability futhi weldability nokuvikelwa esikoteleni-lead ingxubevange enamathela.

Okokuqala, PCB Plating test

Isimiso ukulawula okugeza Plating kuzomele sifake main amakhemikhali ukwakheka okugeza. Ukuze kuzuzwe ukwahlulela lesifanele, amathuluzi ukuhlolwa oluseqophelweni okuthembekile nezindlela kohlaziyo ziyadingeka. Ezinye zokugeza futhi udinga ukusebenzisa izindlela asizayo ezifana ekulinganiseni amandla awo ethize nokubaluleka acid (PH). Ukuze ngqo ukugcina isimo kobuso enamathela, abakhiqizi abaningi PCB manje zamukele indlela yokuhlola inkatho Holstein sika. I ethize inqubo yokuhlola sitsheke test iphaneli 37 ° ukuze nese- ohlangothini olude, ne anode perpendicular futhi ohlangothini olude. Ushintsho anode-to-cathode ibanga uzoba gauge njalo eduze cathode, futhi umphumela waba ukuthi wamanje kanye plate test kushintsha njalo. Kusukela isimo ukusatshalaliswa samanje ipuleti test, kungenzeka ukuba ngokwesayense ukuthi noma ngabe uhlelo kwabantu kwamanje asetshenziswe okugeza Plating kuyinto esezingeni eshiwo inqubo. Umthelela ngqo okuqukethwe okufakiwe phezu kwabantu kwamanje nomthelela izinga ebusweni enamathela kungabuye uyalandelwa.

Okwesibili, PCB eguqa ukuhlolwa negative indlela:

Le ndlela esenziwayo ngoba buso anhlobonhlobo, esidalula engela, kanye evele yayo engenhla nengezansi ingashintshwa ukuze umphumela Kwe-dielectric Heating ngenxa ukuma mpo. Kule, uhla wamanje kanye nekhono zimhlakazile angahlolwa.

Okwesithathu, ukwahlulela kanye inshokutsi:

Ngokusebenzisa oshiwo ngenhla test ndlela, kungenzeka ukuba wahlulele mkhuba nesenzakalo in the ongaphakeme esifundeni samanje ipuleti ukuhlolwa ngesikhathi Plating by ukuqopha langempela ipuleti ukuhlolwa, futhi kungenziwa yahlulelwe ukuthi okufakiwe liyadingeka okungamelanga kwengezwe; nasesikhathini okusezingeni eliphezulu esifundeni wamanje, Plating wenziwa. Ukukhubazeka okunjalo njengoba ebusweni anolaka, blackening futhi ukubukeka okungajwayelekile kungenzeka, okukhombisa ukuthi ukufakwa metal wezinto amanyela emkhandweni okugeza oluthinta ngqo isimo kobuso enamathela. Uma ebusweni enamathela is pitted, kusho ukuthi amaphaphu ebusweni iwukuba zingancishiswa. I ezilimele Plating ungqimba ngokuvamile ubukisa esiningi ngokweqile izithasiselo kanye noqhekeko kuleli okugeza. imihlola enjalo ibonisa ubuqotho ngokugcwele isidingo ukuhlaziywa ngesikhathi esifanele futhi ukulungiswa ukuze ukwakheka amakhemikhali okugeza ihlangabezana nemingcele inqubo ebekiwe kule nqubo. okufakiwe okweqile kanye ukubola udaba eziphilayo kufanele kuthathwe, elihluziwe waliphothula esebenzisa i-carbon isebenze noma okunye okunjalo.

Kafushane, nakuba ukusetshenziswa ubuchwepheshe bama-computer ukulawula ngokuzenzakalelayo ngamunye ngamunye ngokusebenzisa ukuthuthukiswa isayensi nobuchwepheshe, kodwa futhi kufanele ihlolwe esebenzisa usizo, ukuze kuzuzwe umshwalense double. Ngakho-ke, izindlela evame ukusetshenziswa ukulawula esikhathini esidlule kudingeka lisetshenziswe noma olunye ucwaningo kanye nokuthuthukisa izindlela test emisha nemishini ukwenza PCB Plating bese enamathela inqubo neliphelele kunalelo.
