Lefats'eng la lisebelisoa tsa elektroniki, tlhoko ea liboto tsa potoloho tse hatisitsoeng tse sebetsang hantle haholo (PCBs) e lebisitse ho nts'etsopele ea meralo ea Rigid-Flex PCB. Liboto tsena tse ncha li kopanya likarolo tse ntle ka ho fetisisa tsa li-PCB tse thata le tse tenyetsehang, tse fanang ka melemo e ikhethang mabapi le ho boloka sebaka, ho fokotsa boima ba 'mele le ho tšepahala ho matlafalitsoeng. Leha ho le joalo, ntlha e 'ngoe ea bohlokoa eo hangata e hlokomolohuoang ka mokhoa oa ho qapa ke khetho ea soldermask e nepahetseng. Sehlooho sena se tla hlahloba mokhoa oa ho khetha soldermask e loketseng bakeng sa moralo oa Rigid-Flex PCB, ho nahana ka lintlha tse kang likarolo tsa thepa, ho lumellana le ts'ebetso ea tlhahiso ea PCB, le bokhoni bo khethehileng ba Rigid-Flex PCBs.
Ho tseba Moralo oa Rigid-Flex PCB
Li-PCB tse Rigid-Flex ke lebasetere la mahlale a potoloho a thata le a tenyetsehang, a lumellang meralo e rarahaneng e ka kobehang le ho kobeha ntle le ho senya ts'ebetso. The layer stackup ho Rigid-Flex PCBs hangata e na le likarolo tse ngata tsa lisebelisoa tse thata le tse tenyetsehang, tse ka hlophisoang ho fihlela litlhoko tse ikhethileng tsa kopo. Ho feto-fetoha hona ho etsa hore li-PCB tsa Rigid-Flex e be tse loketseng lits'ebetso tsa sefofane, lisebelisoa tsa bongaka le lisebelisoa tsa elektroniki tsa bareki, moo sebaka le boima e leng lintlha tsa bohlokoa.
Karolo ea Soldermask ho Rigid-Flex PCB Design
Soldermask ke lera le sireletsang le sebelisoang holim'a PCB ho thibela borokho ba solder, ho sireletsa khahlanong le tšenyo ea tikoloho, le ho matlafatsa boto e tšoarellang. Ka meralo ea Rigid-Flex PCB, soldermask e tlameha ho amohela litšobotsi tse ikhethang tsa likarolo tse thata le tse tenyetsehang. Mona ke moo khetho ea thepa ea soldermask e bang ea bohlokoa.
Likarolo Tsa Lintho Tseo U Lokelang ho li Nahana
Ha u khetha soldermask bakeng sa Rigid-Flex PCB, ho bohlokoa ho khetha lisebelisoa tse ka mamellang ho kheloha ha mochini le khatello ea tikoloho. Lintlha tse latelang li lokela ho nahanoa:
Ho hanyetsa ho kheloha:The soldermask e tlameha ho khona ho mamella ho kobeha le ho phunya ho etsahalang likarolong tse tenyetsehang tsa PCB. Screen printing flexible liquid photosensitive development soldermask inki ke khetho e babatsehang, kaha e etselitsoe ho boloka botšepehi ba eona tlas'a khatello ea mochine.
Ho hanyetsa Welding:Soldermask e lokela ho fana ka thibelo e matla khahlanong le solder nakong ea kopano. Sena se tiisa hore solder ha e kenelle libakeng tseo e ka bakang lipotoloho tse khutšoane kapa litaba tse ling.
Ho hanyetsa Mongobo:Kaha li-PCB tsa Rigid-Flex li atisa ho sebelisoa libakeng tseo ho tsona ho pepesehelang mongobo ho amehang, soldermask e tlameha ho fana ka khanyetso e ntle ea mongobo ho thibela ho bola le ho senyeha ha potoloho e ka tlaase.
Thibelo ea Tšilafalo:The soldermask lokela ho sireletsa khahlanong le litšila tse ka ama tshebetso ya PCB. Sena se bohlokoa haholo lits'ebetsong moo PCB e ka pepesetsoang lerole, lik'hemik'hale, kapa litšila tse ling.
Ho lumellana le PCB Manufacturing Process
Ntho e 'ngoe ea bohlokoa ea ho khetha mask a solder ke ho lumellana ha eona le ts'ebetso ea tlhahiso ea PCB. Li-PCB tse Rigid-Flex li nka mehato e fapaneng ea tlhahiso, ho kenyelletsa le lamination, etching, le soldering. The soldermask e tlameha ho khona ho mamella mekhoa ena ntle le ho senya kapa ho lahleheloa ke thepa ea eona e sireletsang.
Lamination:Soldermask e lokela ho lumellana le mokhoa oa lamination o sebelisetsoang ho tlama likarolo tse thata le tse tenyetsehang. Ha ea lokela ho nyenyefatsa kapa ho ebola nakong ea mohato ona oa bohlokoa.
Etching:The soldermask e tlameha ho khona ho mamella ts'ebetso ea etching e sebelisoang ho theha mekhoa ea potoloho. E lokela ho fana ka tšireletso e lekaneng ho mesaletsa ea koporo e ka tlaase ha e ntse e lumella ho ts'oaroa ka mokhoa o nepahetseng.
Soldering:Soldermask e lokela ho khona ho mamella mocheso o phahameng o amanang le soldering ntle le ho qhibiliha kapa ho senyeha. Sena se bohlokoa haholo bakeng sa likarolo tse tenyetsehang, tse ka bang kotsing ea ho senyeha ha mocheso.
Matla a PCB a Rigid-Flex
Bokhoni ba li-PCB tsa Rigid-Flex bo fetela ho feta sebopeho sa bona sa 'mele. Li ka ts'ehetsa meralo e rarahaneng e nang le mekhahlelo e mengata, e lumellang ho tsamaisa tsela e rarahaneng le ho beha likarolo. Ha u khetha soldermask, ho bohlokoa ho nahana hore na e tla sebelisana joang le bokhoni bona. Soldermask ha ea lokela ho sitisa ts'ebetso ea PCB empa ho e-na le hoo e ntlafatsa ts'ebetso ea eona.
