Molemo ka ho fetisisa Theknoloji ke e mong oa molemo ka ho fetisisa bahlahisi ba pcb le bafepedi ba boto e hatisitsoeng ka China
Ha ho tluoa tabeng ea ho etsoa ha liboto tsa potoloho tse hatisitsoeng (PCBs) le lisebelisoa tse ling tsa elektroniki, mekhoa e 'meli e sebelisoang hangata ke li-stencil tsa laser le li-stencil tsa etching. Le hoja li-stencil ka bobeli li sebeletsa morero oa ho theha mekhoa e nepahetseng, mekhoa ea bona ea tlhahiso le lisebelisoa li fapane haholo. Sehloohong sena, re tla hlalosa karohano lipakeng tsa li-stencil tsa laser le li-stencil tsa etching.
Stencil ea etching ea lik'hemik'hale ke eng?
Chemical etching ke mokhoa oa ho etsa subtractive o kenyelletsang ho sebelisa kalafo ea lik'hemik'hale ho tlosa thepa ho tsoa ho substrates ka boikhethelo. E sebelisoa haholo ha ho etsoa liboto tsa potoloho tse hatisitsoeng (PCBs) hape e sebelisoa ho theha li-stencil. Ts'ebetso ea ho khabisa li-stencil hangata e kenyelletsa ho kenya stencil ho PCB, ho hloekisa stencil le boto, le ho pheta mehato ena ho fihlela sephetho se lakatsehang se fihletsoe. Ts'ebetso ena ea ho ipheta-pheta e ka nka nako, e etsa hore e be e 'ngoe ea likarolo tse boima haholo tsa ho etsa liboto tse khethehileng tsa elektroniki, likopano tse nyane le liboto tsa potoloho. E le ho hlola liphephetso tse amanang le etching ea setso, bahlahisi ba bang ba se ba qalile ho sebelisa li-stencil tse sehiloeng ka laser e le mokhoa o mong.
Ke hobane'ng ha u sebelisa etching stencil?
Li-stencil tse khabisitsoeng li na le litšobotsi tse latelang tse hlokomelehang.
l Litšenyehelo-ka katleho:
Mokhoa oa ho etsa li-stencil ka kakaretso o bontša hore o na le litšenyehelo tse ngata ha o bapisoa le li-stencil tsa laser.
l Nepahetseng:
Le hoja li sa fihlelle boemo bo nepahetseng joaloka listencil tsa laser, li-stencil tsa etching li ntse li fana ka ho nepahala ho khotsofatsang bakeng sa lits'ebetso tse fapaneng tsa PCB.
l Ho tenyetseha:
Li-stencil tsa etching li ka fetoloa kapa tsa lokisoa habonolo hore li lumellane le liphetoho tsa moralo, tsa etsa hore li tšoanelehe haholo bakeng sa prototyping le tlhahiso e nyane.
Li-stencil tsa etching li sebelisoa hangata lits'ebetsong tsa theknoloji ea through-hole (THT) 'me li loketse hantle bakeng sa likarolo tse hlokang li-depositi tse kholoanyane tsa solder. Ba fumana ho loketse lits'ebetsong tse nang le likarolo tse tlase moo ts'ebeliso ea litšenyehelo e tlang pele haholo.
Laser stencil ke eng?
Li-stencil tsa Laser, tse tsejoang hape e le li-stencil tsa dijithale, ke mofuta oa sejoale-joale oa tlhahiso ea subtractive e sebelisang li-lasers tse laoloang ke komporo ho seha thepa hantle ka libopeho le lipaterone tse itseng. Theknoloji ena e hlahile lefapheng la tlhahiso ho pota 2010-2012, e leng se etsang hore e be ncha indastering.
Leha e le nts'etsopele ea morao-rao, li-stencil tsa laser li fana ka melemo e mengata ho feta li-stencil tse tloaelehileng tsa lik'hemik'hale. Baetsi ba ka rua molemo ka ho fokotsa nako le litlhoko tsa thepa ha ba etsa li-stencil ba sebelisa mokhoa ona. Ho feta moo, li-stencil tse sehiloeng ka laser li fana ka ho nepahala ho ntlafalitsoeng ha li bapisoa le li-etching tsa tsona tsa lik'hemik'hale.
Melemo ea ho sebelisa laser stencil
Li-stencil tsa laser li na le litšobotsi tse latelang tse khethollang.
l Precision ea mohlala
Ho hiroa ha mahlale a ho itšeha ka laser ho etsa hore ho thehoe mekhoa e rarahaneng le e hloekisitsoeng, e netefatsang ho nepahala ha solder peista ho li-PCB.
l Ho feto-fetoha ha maemo
Li-stencil tsa Laser li fana ka likhetho tse bonolo tsa ho itloaetsa le ho li lokisa ho fihlela litlhoko tse ikhethileng tsa moralo, li li etsa hore li tšoanelehe bakeng sa mefuta e mengata ea lits'ebetso tsa PCB.
l Ho tšoarella
Li-stencil tsena li entsoe haholo ka tšepe ea boleng bo holimo, e leng se etsang hore li tšoarelle nako e telele le ho phela nako e telele, kahoo li lumella tšebeliso e ngata.
Li-stencil tsa Laser li fumana ts'ebeliso e pharaletseng lits'ebetsong tsa theknoloji ea holim'a metsi (SMT), moo ho beoa ho nepahetseng ha solder paste ho phethang karolo ea bohlokoa. Tšebeliso ea tsona e molemo ka ho khetheha bakeng sa li-PCB tse phahameng haholo, likaroloana tsa molumo o motle, le potoloho e rarahaneng.
Phapang pakeng tsa etching stencil le laser stencil
Phapang pakeng tsa li-stencil tsa laser le li-stencil tsa etching li ka akaretsoa ka tsela e latelang:
1. Mokhoa oa Tlhahiso:
Li-stencil tsa laser li hlahisoa ka ho itšeha ka laser, ha li-stencil tsa etching li hlahisoa ka katleho ka mokhoa oa lik'hemik'hale.
2. Nepahetse:
Li-stencil tsa laser li fana ka ho nepahala ho holimo, bonyane ke 0.01mm, li etsa hore e be tse loketseng likarolo tsa molumo o motle le li-PCB tse phahameng haholo. Ka lehlakoreng le leng, li-stencil tsa etching li fana ka ho nepahala ho lekaneng bakeng sa lits'ebetso tse nang le litlhoko tse thata haholo.
3. Thepa le ho tšoarella:
Li-stencil tsa Laser li entsoe ka tšepe e sa hloekang, tse netefatsang ho tšoarella ha litšebeliso tse ngata. Ka lehlakoreng le leng, li-stencil tsa etching li entsoe haholo ka koporo kapa nickel, e kanna ea se be le boemo bo ts'oanang ba nako e telele.
4. Likopo:
Li-stencil tsa laser li ipabola lits'ebetsong tsa SMT tse kenyelletsang potoloho e rarahaneng, ha li-stencil tsa etching li fumana ts'ebeliso e kholo lits'ebetsong tsa THT le lits'ebetso tse hlokang li-deposit tse kholoanyane tsa solder.
Khetho pakeng tsa listencil tsa laser le li-stencil tsa etching qetellong e ipapisitse le litlhoko tse ikhethileng tsa ts'ebetso ea tlhahiso ea PCB. Merero e hlokang ho nepahala ho hoholo, likarolo tsa molumo o motle, le potoloho e rarahaneng e ka u tsoela molemo tšebelisong ea li-stencil tsa laser. Ka lehlakoreng le leng, haeba ho boloka litšenyehelo, ho feto-fetoha ha maemo, le ho lumellana le li-depositi tse kholoanyane tsa solder li nka pele, li-stencil tsa etching li fana ka tharollo e sebetsang.
