PCB boto aqueduct tharollo ke taolo ho fetisisa | YONGMINGSHENG

Na ua tseba hore mosebetsi oa PCB boto  aqueduct tharollo ke eng? Sepheo se ka sehloohong sa ho laola ya tharollo PCB plating ke ho boloka dikarolo lik'hemik'hale tsohle ka hare ho fapaneng boletsweng ke tshebetso. The lik'hemik'hale 'meleng le thepa ea barbotage li tiisa feela ka hara meedi boletsweng tshebetso. Ho na le mefuta e mengata ea dithulaganyo sebediswa bakeng sa taolo, ho akarelletsa le tsa lik'hemik'hale fractionation, liteko tsa nama, asiti boleng boikemisetso ba ditharollo, matla a khoheli e itseng ea tharollo kapa boikemisetso ba colorimetric. Dithulaganyo tsena li etselitsoe ho netefatsa ho nepahala, mantsoe a tsoanang le botsitso ba entsprechen ho e hlatsoa. Le ho khetha mokhoa taolo e laolwang ke mofuta oa buildup.

Le hoja mokhoa katisediwa e ka tšeptjoang bakeng sa taolo ea bate, ho na le ho na tiisetso ya hore e barbotage ba lokileng ba tla fumanoa. Ka hona, ke hape ho hlokahala hore ho retelehela ho liteko electroplating. Ka ho khetheha, batho ba bangata electroplating libaka tsa ho tola eketsa additives manyolo ho ntlafatsa sebopeho le tshebetso ya barbotage e le hore ho etsa bonnete ba e ntle ea motlakase 'me phetha molao thepa ea barbotage e. additives tsena ke ho le thata ho li sebelisa ke mekhoa lik'hemik'hale and analysis, 'me ba li hlahlobisisa le bapisoa sebelisa mekhoa teko electroplating, eo sebeletsa e le tlatsetsa ea bohlokoa ho laola lik'hemik'hale ea ho hlapa e. laola eketsehileng kenyeletsa boikemisetso ba maemo tseloe le liphetoho, karaoke set le tlhoekiso. Tsena ho hlokahala hore ka hloko "o ile a re" ho tloha Holstein plating hlapa teko phanele a, 'me joale li hlahlobisisa, hlahlobisisa le inferred ho sechaba poleiti barbotage kabo ho fihlela lintlafatso kapa lintlafatso tsa tshebetso. Mohato morero.

Mohlala, entsprechen la dispersibility phahameng, e khanyang acid e phahameng le tlaase koporo plating hlapa a fetola ke mokhoa lik'hemik'hale phutha; ho phaella ho and analysis lik'hemik'hale, e lik'hemik'hale tharollo tsa koporo e hape tlas'a boleng ph acid e kapa karo-karolelano le Color go lekanya, joalo-joalo Ha lik'hemik'hale e ka hare ho tsamaiso e mengata e fapaneng ka mor'a and analysis, ho ke ke ho hlokahala ho lefa a lebisa tlhokomelo haholo ho liphetoho ya ditekanyetso tse ling le holim 'boemo ba substrate e lokela ho tlotsitsoe, tse kang mocheso tsa tharollo plating, le segokanyipalo sa morao-rao, mokhoa oa ho ntseng bo eketseha' me tšusumetso ea holim kalafo boemo ba substrate ka hlapa ka. Ka ho khetheha, ho hlokahala hore ho ho laola ba inorganic hloeke-zinki ea khanyang acid e koporo plating tharollo, e leng feta lumelleha thulaganyou e ga tlhaloso boleng, 'me ka ho otloloha e ama holim' boemo ba lera la koporo; le thini-etella pele motsoako hlapa tharollo lokela tieo laola diteng tsa litšila koporo, tse kang e itseng e tla ama wettability le weldability le tshireletso ya thini-etella pele motsoako barbotage.

Ntlha ea pele, PCB plating teko

Taolo molao-motheo oa ho plating hlapa lokelang ho kenyelletsa sehlooho se lik'hemik'hale ea ho hlapa e. Ho fihlela kahlolo nepahetse, e tsoetseng pele le e ka tšeptjoang liletsa teko le mekhoa katisediwa lia hlokahala. Ba bang ba libaka tsa ho tola le bona ba lokela ho sebelisa ho bolela thusang tse kang ho lekanya matla a khoheli bona itseng le boleng acid e (ph). E le hore a ka ho toba boloka holim boemo ba barbotage, ba bangata PCB bahlahisi joale amohela mokhoa oa ho Holstein o groove ka teko. The itseng teko Tsamaiso ke ho Shebisa sehlopha teko ke 37 ° ho ea nako e lekanang ka lehlakoreng le nako e telele, le anode perpendicular le hammoho lehlakoreng e telele. The fetola anode-to-cathode hole tla ba le lekanyetsa bokhoni ba kamehla hammoho cathode e, le lebaka hore hona joale hammoho le poleiti teko kamehla fetoha. Ho sechaba sa kabo jwale ya poleiti teko, ho ka etsahala hore saense e fumana hore na segokanyipalo jwale sebelisitsoe ka plating hlapa e ka hare ho fapaneng boletsweng ke tshebetso. Phello e tobileng ea ho tseloe dikahare ka segokanyipalo jwale le phello boleng holim barbotage ka boela ho ketekoa.

Ea bobeli, PCB kobang teko mokhoa mpe:

Mokhoa ona o ile ba amohela hobane masken e mengata e fapaneng, e leng se senola e hlaha ka lehlakoreng le, 'me bokaholimo lona e ka holimo ka tlaase le e tse ikamahanya le phello dielectric ka lebaka la ho sebopeho sa paatsepama. From ena, fapaneng hona joale le bokhoni li qhalakanya ka lekoa.

Boraro, kahlolo le diplomat:

Ka tse boletsoeng ka holimo mokhoa teko, ho ka etsahala ho ahlola ka ho ketsahalo ea ketsahalo e ka tlaase sebakeng jwale ya poleiti teko ka nako e sa plating ke rekota sebele ya poleiti teko, 'me e ka ahloloa hore ho tseloe e hlokahalang ho li ekeletsoa; le ka e phahameng jwale sebakeng, le plating o etsoa. Likoli tse kang holim batallang, blackening 'me ponahalo ea kamehla ka' na etsahala ka eona e bontšang hore kenyelletsoa ha lintlha tsa litšila inorganic tšepe ka ho hlapa le ho toba ama holim 'boemo ba barbotage e. Haeba holim 'a barbotage e pitted, ho bolela hore khatello ea kelello holim'a e lokela ho tsa fokotswa. Senyehileng plating lera hangata e hlahisa e ngata ka tsela e feteletseng ho sebelisoe le li bole kapele ka ho hlapa le. liketsahalo tse joalo li bontša ka botlalo hore ho hlokahala hore and analysis nakong le phetoho e le hore le lik'hemik'hale tsa ho hlapa le kopana tshebetso entsprechen boletsweng tshebetso. Feteletseng tseloe le bole taba manyolo lokela ho ho tšoaroa ka eona, e tlhotliloeng le a hloekisa sebelisa butswe k'habone kapa joang.

Ka bokhutšoanyane, le hoja ho sebelisoa ha lik'homphieutha ho ka tsela e iketsang ho laola e 'ngoe ke e mong ka ntshetsopele ya saense le theknoloji, empa hape e lokela ho hlahlojoa ka ho mokhoa oa ho thuso, e le hore ho fihlela inshorense habeli. Ka lebaka leo, e atisa ho sebelisoa mabapi le ho laola mekhoa nakong e fetileng li lokela ho sebelisoa kapa ho etsa lipatlisiso tse ling le ntshetsopele ya mekhoa teko e ncha le thepa ho etsa hore PCB plating le barbotage thulaganyou e phethahetseng haholo.
