Immisa nooc ayaa ah PVD nano daahan ayaa jira? Maxay yihiin faa'iidooyinka?
Dahaarka PVD
Astaamaha lagu daaweeyo dusha sare ee daweynta PVD: kordhinta nolosha, kordhinta adkaanta, qiimaha kororka, iyo adkeysigiisa sare, iska caabbinta sare, iska caabbinta daxalka oo xoog leh, iska caabinta heerkulka sare, adkeysiga adkeysiga iyo waxqabadka kale ee ka sarreeya ayaa si ballaaran loogu adeegsadaa warshadaha caaryada.
PVD waa Ingiriisiga Uumiga Uumiga (PVD), waxaa loola jeedaa xaalada faakiyuumka, oo leh danab hooseeya, tikniyoolajiyadda dheecaanka qadiimiga ah ee hadda socota, isticmaalka dheecaanka gaaska ee qalabka wax lagu dahaadho ee faaruqinta ah si uumiga saxanka saxanka iyo uumiga uumiga iyo uumiga gaaska adoo adeegsanaya dardargelinta aagga korantada, keena sheyga uumiga iyo badeecada falcelinta Ku shubida qalabka shaqada.
Daahan PVD waxaa badanaa loo yaqaan: daaweynta dusha biraha, daahan, dahaadhay titanium, daahan vacuum, dahaadhay chromium, processing daweynta titanium, PVD, daaweynta dusha sare, saxan titanium, daaweynta dusha sare, processing daahan vacuum, daaweynta dusha, iwm
1. Dusha sare ee caaryada miisaamida saxda ah waxay yeelan kartaa isku dheelitirnaan aad u hooseeya ka dib marka lagu daboolo daahan fayadhowr ah, taas oo yareyn karta xoogsaarka waxqabadka. Ka dib markii caaryada ay ku dahaadhan tahay daahan fayadhowr ah, adkaanta dusha sare ayaa lagu kordhin karaa 5 ilaa 10 jeer, iyo xoqida dusha sare si weyn ayaa loo yareyn karaa.
Ka dib marka qabowga banaan iyo sawirka dhinta lagu dahaadho daahan faakiyuum, khilaafku si weyn ayaa loo yareyn karaa, xoqitaanka iyo xoqidduna si weyn ayaa loo yareyn karaa.
Faa'iidooyinka:
Iska yaree isku-darka isku-dhafka, yaree xoogga mashiinka
Hagaajinta dusha sare, si weyn u dheeree nolosha caaryada
Ka hortag timaha wax soo saarka, jiido, hagaajinta tayada wax soo saarka
Badbaadso dhibaatada soo dejinta caaryada, nadiifinta iyo dib u soo celinta caaryada, hagaajinta waxtarka
2, caaryada balaastigga ah oo ay ugu wacan tahay qaab dhismeedkeeda isku murugsan ayaa go'aamisa dhibaatada ka baaraandegista, sidaas darteed qiimaha waa mid aad u sarreeya, sidaa darteed si loo hagaajiyo nolosha caaryada waa mawduuc weyn, gaar ahaan muraayada iyo dusha sare, waa gaar ahaan fududahay in la xidho, taas oo wuxuu ahaa wax aad u xanuun badan.
Adkaanta dusha sare ee caaryada balaastigga ah ee lagu dahaadhay faakiyuumka ayaa kordhay, iyo iska caabinta abrasion-ka ayaa si aad ah u kordhay Sababtoo ah xoojinta dhamaadka dusha sare iyo hoos u dhigida isukeenida khilaafaadka caaryada, qulqulka alaabada balaastigga ah ayaa kafiican waxsoosaarka caagkuna fududahay in laga qaado caaryada
Isla mar ahaantaana, sababtoo ah qaabdhismeedkiisa shaashaddiisa gaarka ah, daboolka faakiyuumku wuxuu sameeyaa lakab difaac oo cufan dusha sare ee caaryada, kaas oo si wax ku ool ah u xallin kara dhibaatada daxalka. Tan ugu muhiimsan, maxaa yeelay daaheennu ma beddelayo xaaladda dusha sare ee caaryada gabi ahaanba, ha ahaato muraayad ama dusha sare, xitaa shuruudaha aad u sarreeya ee caaryada CD-ga
Faa'iidooyinka:
Xiro iska caabin ah ayaa ka sarreeya, nolosha caaryada ayaa si ballaaran loo dheereeyey
Waqtiga socodka ee walxaha caaggu wuu dheer yahay oo saameynta buuxintu way ka fiican tahay
Tayada dusha sare ee badeecooyinka balaastigga ah ayaa la hagaajiyay oo heerka cilladda ayaa la dhimay
Demouldinging waa sahlan tahay, xitaa iska ilaali isticmaalka wakiilka demouldinging
Si wax ku ool ah looga hortago walxaha waxyeelleeya ee ka yimaada xoqidda shaxda caaryada
Caaryadu way fududahay in la nadiifiyo wareegga nadiifintuna wuu dheer yahay
3. Dahaarka faakiyuumka ee warshadaha elektaroonigga ah laguma dabaqo oo keliya caaryada mindi ee qalabka mashiinada qalabka iyo mashiinka caagga ah, laakiin sidoo kale aad ayaa loogu xagliyaa warshadaha elektaroonigga ah sababtoo ah adkaanta dusha sare, dhammaystirka wanaagsan iyo saxsanaanta sare.
Tusaale ahaan, daab-galka, baakadaha IC-ga ayaa dhinta, farsamaynta PCB ee qashin-qodista micro-qoditaanka, godka PCB-ka ee dhinta, dahab-farta dhinta, iwm, dahaadhida alaabtan oo keliya ma xallinayso dhibaatooyin badan oo dadka isticmaala ah, laakiin sidoo kale waxay u keentaa faa'iidooyin badan.
Faa'iidooyinka:
Dhumucda dahaadhku waa mid aad u dhuuban, oo buuxin kara shuruudaha saxnaanta sare ee warshadaha elektaroonigga oo gebi ahaanba bey'adda u fiican. Waxay la kulmi kartaa dhammaan noocyada shuruudaha amniga (sida tilmaamaha RoHS) si loo hagaajiyo iska caabbinta qalabka ama qaybaha loona hubiyo xasilloonida tayada wax soo saarka
