PCB ke eng?
PCB e bua ka Printed Circuit Board, e leng sejari sa khokahano ea motlakase ea likarolo tsa elektroniki le karolo ea mantlha ea lihlahisoa tsohle tsa elektroniki. PCB e boetse e tsejoa e le PWB (Printed Wire Board).
Ke mefuta efe ea lisebelisoa tsa PCB tse ka khaoloang ka li-cutter tsa laser?
Mefuta ea lisebelisoa tsa PCB tse ka khaoloang ka sehahi se nepahetseng sa laser se kenyelletsa liboto tsa potoloho tse hatisitsoeng ka tšepe, liboto tsa potoloho tse hatisitsoeng ka pampiri, liboto tsa potoloho tse hatisitsoeng ka khalase ea epoxy, liboto tsa potoloho tse hatisitsoeng tsa substrate, liboto tse khethehileng tse hatisitsoeng tsa substrate le substrate e 'ngoe. lisebelisoa.
Li-PCB tsa pampiri
Mofuta ona oa boto ea potoloho e hatisitsoeng e entsoe ka pampiri ea fiber e le thepa e matlafatsang, e kolobisitsoeng ka tharollo ea resin (phenolic resin, epoxy resin) ebe e omisitsoe, ebe e koahetsoe ka foil ea koporo ea electrolytic e koahetsoeng ka sekhomaretsi, ebe e hatelloa ka tlas'a mocheso o phahameng le khatello e phahameng. . Ho ea ka litekanyetso tsa American ASTM/NEMA, mefuta ea mantlha ke FR-1, FR-2, FR-3 (tse kaholimo ke tse thibelang malakabe XPC, XXXPC (tse kaholimo ha li chese lelakabe). tlhahiso ea sekala ke liboto tsa potoloho tse hatisitsoeng tsa FR-1 le XPC.
Li-PCB tsa fiberglass
Mofuta ona oa boto ea potoloho e hatisitsoeng o sebelisa epoxy kapa epoxy resin e fetotsoeng e le thepa ea motheo ea sekhomaretsi, le lesela la fiber ea khalase e le thepa e matlafatsang. Hajoale ke boto e kholo ka ho fetisisa e hatisitsoeng lefatšeng ka bophara ebile ke mofuta o sebelisoang haholo oa boto ea potoloho e hatisitsoeng. Boemong ba ASTM/NEMA, ho na le mefuta e mene ea lesela la epoxy fiberglass: G10 (e sa chesehang ka mollo), FR-4 (lelakabe la lelakabe). G11 (boloka matla a mocheso, eseng ho thibela lelakabe), FR-5 (boloka matla a mocheso, ho thibela lelakabe). Ha e le hantle, lihlahisoa tse sa chesehang li ntse li fokotseha selemo le selemo, 'me FR-4 e ikarabella bakeng sa bongata bo boholo.
Li-PCB tse kopantsoeng
Mofuta ona oa boto ea potoloho e hatisitsoeng e itšetlehile ka tšebeliso ea lisebelisoa tse fapaneng tsa ho matlafatsa ho theha thepa ea motheo le lisebelisoa tsa motheo. Li-substrates tsa copper clad laminate tse sebelisoang haholo-holo ke letoto la CEM, moo CEM-1 le CEM-3 li emelang haholo. Lesela la motheo la CEM-1 ke lesela la fiber fiber, thepa ea mantlha ke pampiri, resin ke epoxy, e thibelang malakabe. Lesela la motheo la CEM-3 ke lesela la fiber ea khalase, thepa ea mantlha ke pampiri ea fiber ea khalase, resin ke epoxy, e thibelang mollo. Litšobotsi tsa mantlha tsa boto ea potoloho e hatisitsoeng e kopantsoeng e lekana le FR-4, empa litšenyehelo li tlase, 'me ts'ebetso ea machining e betere ho feta FR-4.
Li-PCB tsa tšepe
Metal substrates (aluminium base, koporo base, iron base or Invar steel) e ka etsoa hore e be liboto tsa potoloho e le 'ngoe, tse habeli, tse nang le mekhahlelo e mengata kapa liboto tsa potoloho tse hatisitsoeng tsa tšepe ho latela likarolo le ts'ebeliso ea tsona.
PCB e sebelisetsoa eng?
PCB (boto ea potoloho e hatisitsoeng) e sebelisoa ho lisebelisoa tsa elektroniki tsa bareki, lisebelisoa tsa indasteri, lisebelisoa tsa bongaka, lisebelisoa tsa mollo, lisebelisoa tsa polokeho le ts'ireletso, lisebelisoa tsa mehala ea puisano, li-LED, likarolo tsa koloi, lits'ebetso tsa maritime, lisebelisoa tsa sefofane, ts'ireletso le ts'ebetso ea sesole, hammoho le tse ling tse ngata. lits'ebetso. Likopong tse nang le litlhoko tse phahameng tsa polokeho, li-PCB li tlameha ho fihlela litekanyetso tsa boleng bo holimo, kahoo re tlameha ho nka lintlha tsohle tsa ts'ebetso ea tlhahiso ea PCB ka botebo.
Laser cutter e sebetsa joang ho li-PCB?
Pele ho tsohle, ho seha PCB ka laser ho fapane le ho seha ka mechini e kang ho sila kapa ho hatakela. Ho itšeha ka laser ho ke ke ha siea lerōle ho PCB, kahoo ho ke ke ha ama tšebeliso ea morao-rao, 'me khatello ea mochine le khatello ea mocheso e hlahisoang ke laser ho likarolo ha e na thuso,' me mokhoa oa ho itšeha o bonolo haholo.
Ho phaella moo, theknoloji ea laser e ka finyella litlhoko tsa bohloeki. Batho ba ka hlahisa PCB ka bohloeki bo phahameng le boleng bo phahameng ka theknoloji ea ho itšeha ka laser ea STYLECNC ho tšoara thepa ea motheo ntle le carbonization le discoloration. Ho phaella moo, e le ho thibela ho hlōleha ha mokhoa oa ho itšeha, STYLECNC e boetse e entse meralo e amanang le lihlahisoa tsa eona ho li thibela. Ka hona, basebelisi ba ka fumana sekhahla se phahameng haholo sa tlhahiso tlhahisong.
Ha e le hantle, feela ka ho fetola li-parameter, motho a ka sebelisa sesebelisoa se tšoanang sa ho itšeha ka laser ho sebetsana le lisebelisoa tse sa tšoaneng, tse kang mekhoa e tloaelehileng (e kang FR4 kapa ceramics), insulated metal substrates (IMS) le system-in-packages (SIP). Ho feto-fetoha ha maemo ho nolofalletsa li-PCB ho sebelisoa maemong a fapaneng, joalo ka lisistimi tse futhumatsang kapa tse futhumatsang tsa lienjineri, li-chassis sensors.
Moqaping oa PCB, ha ho na lithibelo mabapi le kemiso, radius, label kapa likarolo tse ling. Ka ho itšeha ka ho feletseng, PCB e ka behoa ka ho toba tafoleng, e leng ho ntlafatsang haholo katleho ea tšebeliso ea sebaka. Ho khaola li-PCB ka laser ho boloka thepa e fetang 30% ha e bapisoa le mekhoa ea ho itšeha ka mochini. Sena ha se thuse feela ho fokotsa litšenyehelo tsa ho hlahisa li-PCB tsa sepheo se itseng, empa hape se thusa ho aha tikoloho e nang le botsoalle ea tikoloho.
Mekhoa ea ho itšeha ea laser ea STYLECNC e ka kopanngoa habonolo le mekhoa e teng ea Manufacturing Execution Systems (MES). Sistimi e tsoetseng pele ea laser e tiisa botsitso ba ts'ebetso ea ts'ebetso, athe karolo ea othomathike ea sistimi e boetse e nolofatsa ts'ebetso ea ts'ebetso. Ka lebaka la matla a phahameng a mohloli o kopantsoeng oa laser, mechine ea kajeno ea laser e bapisoa ka ho feletseng le mekhoa ea mechine ho latela lebelo la ho itšeha.
Ho feta moo, litšenyehelo tsa ts'ebetso ea sisteme ea laser li tlase kaha ha ho na likarolo tse roaloang joalo ka lihlooho tsa ho sila. Litsenyehelo tsa likarolo tse ncha le nako ea ho theoha ka lebaka leo li ka qojoa.
Ke mefuta efe ea li-cutters tsa laser tse sebelisetsoang ho etsa PCB?
Ho na le mefuta e meraro e atileng haholo ea li-cutter tsa laser tsa PCB lefatšeng. U ka etsa khetho e nepahetseng ho latela litlhoko tsa hau tsa khoebo tsa PCB.
