Kodi PCB ndi chiyani?
PCB imatanthawuza ku Printed Circuit Board, yomwe ndi chonyamulira cholumikizira magetsi pazigawo zamagetsi ndi gawo lalikulu lazinthu zonse zamagetsi. PCB imadziwikanso kuti PWB (Printed Wire Board).
Ndi mitundu yanji ya zida za PCB zomwe zingadulidwe ndi odula laser?
Mitundu ya zida za PCB zomwe zimatha kudulidwa ndi chodulira cholondola cha laser chimaphatikizapo matabwa opangidwa ndi zitsulo, mapepala opangidwa ndi mapepala osindikizira, matabwa a epoxy galasi fiber kusindikizidwa matabwa ozungulira, matabwa ozungulira opangidwa ndi gawo lapansi, matabwa apadera a gawo lapansi osindikizidwa ndi gawo lapansi lina. zipangizo.
Mapepala a PCB
Mtundu uwu wa bolodi losindikizidwa limapangidwa ndi pepala la fiber monga chowonjezera, choviikidwa mu njira yothetsera utomoni (phenolic resin, epoxy resin) ndi zouma, kenako zokutira ndi glue- TACHIMATA electrolytic mkuwa zojambulazo, ndi mbamuikha pansi kutentha ndi kuthamanga kwambiri. . Malinga ndi miyezo ya American ASTM/NEMA, mitundu ikuluikulu ndi FR-1, FR-2, FR-3 (ili pamwambapa ndi XPC yoletsa moto, XXXPC (yomwe ili pamwambapa ndi yosawotcha moto). Mitundu yomwe imagwiritsidwa ntchito kwambiri komanso yayikulu- kupanga masikelo ndi FR-1 ndi XPC yosindikizidwa matabwa ozungulira.
Fiberglass PCBs
Mtundu uwu wa bolodi wosindikizidwa wadera umagwiritsa ntchito epoxy kapena utomoni wosinthidwa wa epoxy monga maziko a zomatira, ndi nsalu zamagalasi za fiber monga kulimbikitsa. Pakalipano ndi gulu lalikulu kwambiri padziko lonse lapansi losindikizidwa komanso mtundu wogwiritsidwa ntchito kwambiri wa bolodi losindikizidwa. Muyeso wa ASTM/NEMA, pali mitundu inayi ya nsalu za epoxy fiberglass: G10 (yosawotcha moto), FR-4 (yobwezeretsa moto). G11 (sungani mphamvu ya kutentha, osati kutentha kwa moto), FR-5 (sungani mphamvu ya kutentha, sungani kutentha kwa moto). M'malo mwake, zinthu zomwe siziwotcha moto zikucheperachepera chaka ndi chaka, ndipo FR-4 ndiyomwe imapanga zambiri.
Ma PCB osiyanasiyana
Mtundu uwu wa bolodi wosindikizidwa wadera umachokera ku kugwiritsa ntchito zipangizo zosiyanasiyana zolimbikitsira kupanga zinthu zoyambira ndi zapakati. Magawo a copper clad laminate omwe amagwiritsidwa ntchito makamaka ndi mndandanda wa CEM, womwe CEM-1 ndi CEM-3 ndi omwe akuyimira kwambiri. CEM-1 m'munsi nsalu ndi galasi CHIKWANGWANI nsalu, mfundo yaikulu ndi pepala, utomoni ndi epoxy, retardant lawi. CEM-3 m'munsi nsalu ndi galasi CHIKWANGWANI nsalu, zakuthupi ndi galasi CHIKWANGWANI pepala, utomoni ndi epoxy, retardant lawi. Makhalidwe oyambira a gulu lachigawo losindikizidwa ndi gulu lophatikizika ndi ofanana ndi FR-4, koma mtengo wake ndi wotsika, ndipo magwiridwe antchito amamachining ndi abwino kuposa FR-4.
Zitsulo PCBs
Magawo azitsulo (zitsulo zotayidwa, maziko amkuwa, chitsulo chachitsulo kapena chitsulo cha Invar) zitha kupangidwa kukhala matabwa ang'onoang'ono, awiri, angapo osanjikiza zitsulo kapena zitsulo zazikuluzikulu zosindikizidwa zama board malinga ndi mawonekedwe awo ndi ntchito.
Kodi PCB imagwiritsidwa ntchito chiyani?
PCB (yosindikizidwa dera bolodi) amagwiritsidwa ntchito pa ogula zamagetsi, zipangizo mafakitale, zipangizo zachipatala, zipangizo moto, chitetezo & chitetezo zipangizo, zipangizo telecommunication, LEDs, zigawo magalimoto, ntchito panyanja, zigawo zazamlengalenga, chitetezo & ntchito zankhondo, komanso zina zambiri. mapulogalamu. Mu ntchito ndi zofunika chitetezo mkulu, PCBs ayenera kukumana mfundo zapamwamba, choncho tiyenera tsatanetsatane wa ndondomeko kupanga PCB mozama.
Kodi laser cutter imagwira ntchito bwanji pa PCBs?
Choyamba, kudula PCB ndi laser ndikosiyana ndi kudula ndi makina monga mphero kapena kupondaponda. Kudula kwa laser sikudzasiya fumbi pa PCB, kotero sikungakhudze kugwiritsa ntchito pambuyo pake, ndipo kupsinjika kwamakina ndi kupsinjika kwamatenthedwe kumayambitsidwa ndi laser ku zigawo zake ndizosavomerezeka, ndipo kudula kumakhala kofatsa.
Kuphatikiza apo, ukadaulo wa laser ungakwaniritse zofunikira zaukhondo. Anthu akhoza kutulutsa PCB ndi ukhondo mkulu ndi mkulu khalidwe mwa STYLECNC a laser kudula luso kuchitira zinthu m'munsi popanda carbonization ndi discoloration. Kuphatikiza apo, pofuna kupewa zolephera pakudulira, STYLECNC yapanganso mapangidwe okhudzana ndi zinthu zake kuti apewe. Chifukwa chake, ogwiritsa ntchito amatha kupeza zokolola zambiri pakupanga.
M'malo mwake, pongosintha magawo, mutha kugwiritsa ntchito chida chodulira cha laser chofananira pokonza zinthu zosiyanasiyana, monga ntchito wamba (monga FR4 kapena ceramics), magawo azitsulo opangidwa ndi insulated (IMS) ndi dongosolo-mu-packages (SIP). Kusinthasintha kumeneku kumathandizira ma PCB kuti agwiritsidwe ntchito pazinthu zosiyanasiyana, monga kuzirala kapena kutenthetsa kwa injini, masensa a chassis.
Mu kapangidwe ka PCB, palibe zoletsa pa autilaini, utali wozungulira, chizindikiro kapena mbali zina. Kupyolera mu kudula mozungulira, PCB ikhoza kuikidwa patebulo, zomwe zimathandizira kwambiri kugwiritsa ntchito malo. Kudula ma PCB ndi laser kumapulumutsa zinthu zopitilira 30% poyerekeza ndi njira zodulira makina. Izi sizimangothandiza kuchepetsa mtengo wopangira ma PCB acholinga chapadera, komanso zimathandiza kumanga malo ochezeka achilengedwe.
Makina odulira laser a STYLECNC amatha kuphatikizidwa mosavuta ndi Manufacturing Execution Systems (MES). Makina otsogola a laser amatsimikizira kukhazikika kwa ntchitoyo, pomwe mawonekedwe odziyimira pawokha amathandiziranso ntchitoyo. Chifukwa cha mphamvu yapamwamba ya gwero la laser Integrated, makina a laser amakono amafanana mokwanira ndi machitidwe opangira makina othamanga mofulumira.
Kuphatikiza apo, ndalama zogwiritsira ntchito makina a laser ndizotsika chifukwa palibe zida zobvala monga mitu yamphero. Mtengo wa magawo olowa m'malo ndi nthawi yocheperako zitha kupewedwa.
Ndi mitundu yanji ya odula laser omwe amagwiritsidwa ntchito popanga PCB?
Pali mitundu itatu yodziwika kwambiri ya PCB laser cutters padziko lapansi. Mutha kupanga chisankho choyenera malinga ndi zosowa zanu zamabizinesi opangira PCB.
CO2 Laser Cutters for For Custom PCB Prototype
Makina odulira laser a CO2 amagwiritsidwa ntchito kudula ma PCB opangidwa ndi zinthu zopanda zitsulo, monga mapepala, magalasi a fiberglass, ndi zida zina zophatikizika. CO2 laser PCB cutters ndi mitengo kuchokera $3,000 kuti $12,000 kutengera mbali zosiyanasiyana.
Makina Odulira Fiber Laser a Custom PCB Prototype
Wodula CHIKWANGWANI laser ntchito kudula PCBs zopangidwa zitsulo, monga aluminiyamu, mkuwa, chitsulo, ndi Invar zitsulo.
