Ts'ebetsong ea nts'etsopele ea lihlahisoa tsa elektroniki, bopaki ba PCB ke sehokelo sa bohlokoa.Ka tsoelopele ea theknoloji le keketseho ea tlhoko ea 'maraka, lits'ebeletso tsa prototyping tse potlakileng tsa PCB li ka ntlafatsa haholo lebelo la ho qala sehlahisoa le tlholisano.Joale, tšebeletso ea prototyping e potlakileng ea PCB e kenyelletsa eng?
Litšebeletso tsa tlhahlobo ea boenjiniere
Mehatong ea pele ea prototyping ea PCB, lits'ebeletso tsa tlhahlobo ea boenjiniere li bohlokoa.Litšebeletso tsa tlhahlobo ea boenjiniere li kenyelletsa lienjineri tse hloahloa ho lekola litšoantšo tsa meralo ho netefatsa hore li fihlela litlhoko tsa moralo le litlhoko tsa tlhahiso.Ka moralo oa pele le tlhahlobo ea boenjiniere, liphoso tlhahisong e latelang li ka fokotsoa, litšenyehelo tsa fokotsoa, 'me potoloho ea ntlafatso ka kakaretso e khutsufatsoe.
Khetho ea thepa le litšebeletso tsa ho reka
Khetho ea thepa ke e 'ngoe ea lihokelo tsa bohlokoa ho prototyping ea PCB.Lihlahisoa tse fapaneng tsa elektroniki li na le litlhoko tse fapaneng tsa thepa.Hoa hlokahala ho khetha thepa e nepahetseng ea motheo, botenya ba foil ea koporo le mokhoa oa phekolo ea holim'a metsi ho latela boemo bo khethehileng ba kopo.Li-substrates tse tloaelehileng li kenyelletsa FR-4, substrates ea aluminium, le lisebelisoa tse phahameng haholo.Likhamphani tsa litšebeletso tsa prototyping tse potlakileng hangata li fana ka lethathamo la lisebelisoa tse fapaneng ho fihlela litlhoko tsa bareki ba fapaneng.
Litšebeletso tsa tlhahiso
1. Phetisetso ea mohlala: Apara lesela la lisebelisoa tsa photosensitive (tse kang filimi e omeletseng kapa filimi e metsi) holim'a foil ea koporo, ebe u sebelisa leseli la UV kapa laser ho pepesa mohlala, ebe o tlosa likarolo tse sa hlokahaleng ka mokhoa oa tsoelo-pele.
2. Etching: Tlosa foil e feteletseng ea koporo ka tharollo ea lik'hemik'hale kapa thekenoloji ea plasma etching, u siea feela mokhoa o hlokahalang oa potoloho.
3. Ho cheka le ho pola: Hala tse fapa-fapaneng tse hlokehang ka likoti le masoba a foufetseng / a patiloeng holim'a boto, ebe o tsamaisa electroplating ho netefatsa conductivity ea lerako la lesoba.
4. Lamination le lamination: Bakeng sa mapolanka a mangata, lera le leng le le leng la mapolanka a potoloho le hloka ho kopanngoa hammoho le resin le ho hatelloa tlas'a mocheso o phahameng le khatello e phahameng.
5. Phekolo ea sefahleho: E le ho ntlafatsa weldability le ho thibela oxidation, phekolo ea holim'a metsi e atisa ho etsoa.Mekhoa e tloaelehileng ea kalafo e kenyelletsa HASL (hot air leveling), ENIG (gold plating) le OSP (organic coating protection).
lits'ebeletso tsa ho hlaba le ho hlahloba
1. Teko ea ts'ebetso: Sebelisa sehlahlobi se fofang kapa setsi sa liteko ho leka ntlha e 'ngoe le e 'ngoe ea khokahanyo ea motlakase botong ea potoloho ho netefatsa hore ho tsoelapele le ho kenya letsoho ho fihlela litlhoko tsa moralo.
2. Tlhahlobo ea ponahalo: Ka thuso ea microscope kapa thepa ea ho hlahloba ka mokhoa o itekanetseng (AOI), hlahloba ka hloko ponahalo ea boto ea PCB ho fumana le ho lokisa liphoso leha e le life tse ka amang tshebetso.
3. Teko ea tšebetso: Liboto tse ling tse rarahaneng tsa potoloho le tsona li hloka ho lekoa ka mokhoa o ts'oanang ho etsisa tikoloho ea ts'ebeliso le ho hlahloba hore na ts'ebetso ea tsona ea ts'ebetso e fihlela litebello.
Litšebeletso tsa ho paka le ho romella
Liboto tsa PCB tse fetisang tlhahlobo le tlhahlobo li hloka ho phutheloa hantle ho thibela tšenyo nakong ea lipalangoang.Sephutheloana se fanoang ke lits'ebeletso tsa prototyping tse potlakileng hangata li kenyelletsa liphutheloana tse thibelang maemo, liphutheloana tse thibelang ho ts'oha, le liphutheloana tse sa keneleng metsi.Kamora ho paka ho phetheloa, k'hamphani ea lits'ebeletso tsa bopaki e tla isa lihlahisoa ho bareki kapele ka ho fana ka maikutlo kapa ka thepa e inehetseng ho netefatsa hore tsoelo-pele ea lipatlisiso le nts'etsopele ha e amehe.
Tšehetso ea tekheniki le tšebeletso ea morao-rao ea thekiso
Litšebeletso tsa prototyping tse potlakileng tsa PCB ha li fane feela ka tlhahiso le tlhahiso, empa hape li kenyelletsa tšehetso e felletseng ea tekheniki le ts'ebeletso ea kamora thekiso.Ha ba kopana le mathata kapa ho hloka botsitso nakong ea moralo, bareki ba ka ikopanya le sehlopha sa tšehetso ea tekheniki ka nako efe kapa efe ho fumana tataiso le likeletso tsa litsebi.Esita le ka mor'a hore sehlahisoa se fanoe, haeba bareki ba kopana le mathata leha e le afe a boleng kapa ba hloka ntlafatso e eketsehileng, sehlopha sa tšebeletso ea ka mor'a thekiso se tla arabela ka potlako le ho a rarolla, ho netefatsa khotsofalo le tšepo ea bareki.
Ts'ebeletso ea prototyping e potlakileng ea boto ea PCB e akaretsa lintlha tse ngata ho tloha tlhahlobong ea projeke, khetho ea thepa, tlhahiso le tlhahiso ho isa litekong, ho paka, ho fana le litšebeletso tsa kamora thekiso.Ts'ebetso e sebetsang hantle le khokahano e se nang moeli ea sehokelo ka seng e ke ke ea ntlafatsa haholo ts'ebetso ea R&D feela, empa hape e fokotsa litšenyehelo tsa tlhahiso le ho ntlafatsa boleng ba sehlahisoa.
