Kodi SMT PCB assembly ndi chiyani?
Msonkhano wa SMT PCB ndi njira yomwe zida zamagetsi zimayikidwa mwachindunji pamwamba pa bolodi losindikizidwa.Iwo amalola zigawo zikuluzikulu kuti wokwera mwachindunji pamwamba phiri PCB.Tekinoloje iyi imathandiza kuchepetsa zigawo zikuluzikulu.
Ukadaulo wa Surface Mount ndiye njira yomwe imagwiritsidwa ntchito kwambiri.Choncho, ntchito yake ndi yaikulu kwambiri.Monga momwe teknoloji yokwera pamwamba imaphatikizapo zowonjezera zowonjezera zamagetsi mu malo ang'onoang'ono, zipangizo zambiri masiku ano zimagwiritsa ntchito teknoloji yokwera pamwamba.Kotero pamene miniaturization imakhala yofunika kwambiri, kufunikira kwa teknoloji ya SMT kumaonekera.
PCBFuture ili ndi zaka zopitilira 10 mumsonkhano wa SMT PCB.Kupyolera mu ndondomeko ya msonkhano wa SMT wokha, ma board athu ozungulira amatha kuwonetsetsa kuti zinthu zikuyenda bwino pamapulogalamu ovuta kwambiri.
Kodi ndondomeko ya SMT PCB Assembly ndi yotani?
Njira yogwiritsira ntchito SMT kupanga zipangizo za PCB zimaphatikizapo kugwiritsa ntchito makina opangira makina kuti asonkhanitse zipangizo zamagetsi.Makinawa amayika zinthu izi pa bolodi la dera, koma izi zisanachitike, fayilo ya PCB iyenera kufufuzidwa kuti itsimikizire kuti ilibe vuto lomwe likukhudza kupanga ndi magwiridwe antchito a chipangizocho.Pambuyo potsimikizira kuti chirichonse chiri changwiro, ndondomeko ya msonkhano wa SMT PCB sikungowonjezera kugulitsa ndi kuika zinthu kapena mankhwala pa PCB.Njira yopangira zotsatirazi iyeneranso kutsatiridwa.
1. Ikani solder phala
Gawo loyamba pakusonkhanitsa bolodi la SMT PCB ndikuyika phala la soldering.Phala lingagwiritsidwe ntchito pa PCB kudzera paukadaulo waukadaulo wa silika.Itha kugwiritsidwanso ntchito pogwiritsa ntchito stencil ya PCB yopangidwa kuchokera ku fayilo yofananira ya CAD.Muyenera kudula ma stencil pogwiritsa ntchito laser ndikugwiritsa ntchito phala la soldering kumadera omwe mudzagulitsa zigawozo.Ntchito ya solder paste iyenera kuchitidwa pamalo ozizira.Mukamaliza kulembetsa, mutha kudikirira kwakanthawi kuti musonkhe.
2. Kuyang'ana phala lanu la solder
Pambuyo pa phala la solder likugwiritsidwa ntchito pa bolodi, sitepe yotsatira ndiyo kuyang'ana nthawi zonse kudzera mu njira zowunika za solder phala.Izi ndizofunikira, makamaka pofufuza malo a solder phala, kuchuluka kwa phala logwiritsidwa ntchito, ndi zina zofunika.
3. Kutsimikizira ndondomeko
Ngati gulu lanu la PCB likugwiritsa ntchito zigawo za SMT mbali zonse, padzakhala kofunika kulingalira kubwereza zomwezo kuti zitsimikizidwe zachiwiri.mudzatha kutsata nthawi yoyenera yowonetsera phala la solder kutentha kwa chipinda muno.Apa ndi pamene gulu lanu lozungulira likukonzekera kusonkhanitsidwa.Zigawozi zidzakhalabe zokonzekera fakitale yotsatira.
4. Zida za Assembly
Izi makamaka zimagwirizana ndi BOM (Bill of Equipment) yogwiritsidwa ntchito ndi CM pakusanthula deta.Izi zimathandizira kupanga zida zamagulu a BOM.
5. Zida zosungiramo zinthu
Gwiritsani ntchito barcode kuti mutulutse mu katundu ndikuyiyika mu zida zochitira msonkhano.Zigawozo zikayikidwa kwathunthu mu kit, zimatengedwa kupita ku makina osankha ndi malo otchedwa ukadaulo wapamwamba kwambiri.
6. Kukonzekera kwa zigawo zoyikapo
Chida chosankha ndi malo chimagwiritsidwa ntchito pano kuti chigwiritsire ntchito chinthu chilichonse chophatikiza.Makinawa amagwiritsanso ntchito katiriji yomwe imabwera ndi kiyi yapadera yomwe imagwirizana ndi zida za msonkhano wa BOM.Makinawa adapangidwa kuti aziuza gawo lomwe katiriji imagwira.
Kodi msonkhano wa SMT PCB ungapereke chiyani?
Ma board osindikizira a SMT ali ndi maubwino osiyanasiyana.Ubwino wofunikira kwambiri wa SMT ndi kukula kochepa komanso kulemera kopepuka.Kuphatikiza apo, maubwino ena a SMT ndi awa:
1. Kupanga mwachangu: matabwa ozungulira amatha kusonkhanitsidwa popanda kubowola, zomwe zikutanthauza kuti kupanga kumathamanga kwambiri.
2. Kuthamanga kwapamwamba kwambiri: Ndipotu, ichi ndi chimodzi mwa zifukwa zazikulu zomwe SMT yakhala teknoloji yosankha lero.
3. Zodzichitira pagulu: imatha kuzindikira zodzichitira ndi zabwino zake zambiri.
4. Mtengo: Mtengo wa tizigawo tating'onoting'ono nthawi zambiri umakhala wotsika kuposa wa zida zapabowo.
5. Kuchulukana: Amalola kuti zigawo zambiri ziziyikidwa mbali zonse za bolodi losindikizidwa la SMT.
6. Design kusinthasintha: Kupyolera mu dzenje ndi kupanga chigawo cha SMT kungaphatikizidwe kuti apereke ntchito zambiri.
7. Kuchita bwino: Malumikizidwe a SMT ndi odalirika kwambiri, kotero bolodi imatha kukonza magwiridwe antchito.
Chifukwa chiyani kusankha msonkhano wathu wa SMT PCB?
PCBFuture idakhazikitsidwa mu 2009, ndipo tili ndi zaka zopitilira khumi mumsonkhano wa SMT PCB.Tadzipereka kuti tikwaniritse zosowa za makasitomala athu ochokera kumafakitale osiyanasiyana munthawi yamtundu, kutumiza, kutsika mtengo komanso yankho la PCB.Komanso kupereka utumiki wapadera makonda.Timasintha PCB mogwirizana ndi bajeti yanu ndikusunga nthawi yanu kuti mupeze msika.
1. Maola 24 pa intaneti.
2. Utumiki wofulumira wa maola 12 wa chitsanzo cha PCB.
3. Mitengo yotsika mtengo komanso yopikisana.
4. Kuyesedwa kwa ntchito kutengera zomwe kasitomala akufuna.
5. Gulu lathu la akatswiri ndi odalirika limakupangitsani kukhala kosavuta kukhazikitsa kapena kuthetsa mavuto.Izi ndi zomwe tikufuna kukhutiritsa makasitomala athu.Timapereka mautumiki athunthu kuchokera pamapangidwe ozungulira mpaka zida zomalizidwa zama board osindikizidwa.Ndife okondwa nthawi zonse kukupatsani mautumiki apamwamba.
6. Zaka zambiri za 10 m'malo ogula a Electronics Components.
7. Timapereka ma PCB anu mwachindunji komanso mwachangu mukamaliza kuchokera kufakitale.
8. Factory yodalirika ya SMT yokhala ndi 8 SMT Lines, 100% Mayesero a Ntchito, Prototype Production, Njira Yothandizira Kwambiri.
9. Tili ndi luso lamakono kwambiri kuti tiwonetsetse kuti timapereka zinthu zabwino.Tilinso ndi zida zokwanira kuti tikupatseni misonkhano ya SMT ya turnkey yomwe imakuchotserani zovuta zonse.
Ndondomeko ya msonkhano wa SMT ikusintha njira yopangira PCB ndikuitengera pamlingo wina.Iyi ndi teknoloji yotsika mtengo, yothandiza komanso yodalirika popanga ma PCB.Chokhacho chomwe chikuyembekezeka mtsogolomo ndikuwongolera ukadaulo wonse wa SMT PCB popeza si njira yophweka.Nkhani yabwino ndiyakuti ngakhale lero, mutha kupeza matabwa odalirika a PCB pamtengo wotsika mtengo.Komabe, ndikofunikira kulumikizana ndi injiniya wodalirika kapena wopanga zida zoyenera komanso chidziwitso kuti mukwaniritse zomwe mukufuna.Pofuna kukuthandizani kumvetsetsa wopanga bwino, mutha kuganizira nthawi zonse kugwiritsa ntchito zida zamakono, zida zapamwamba, mitengo yotsika mtengo, ndi opanga omwe amapereka nthawi yake.
Ntchito ya PCBFuture ndikupereka makampani opanga zodalirika zapamwamba za PCB ndi ntchito zapagulu kuyambira pa prototype mpaka kupanga m'njira yotsika mtengo.Cholinga chathu ndikuthandizira wogwiritsa ntchito aliyense kukhala wodziwa bwino ntchito zosiyanasiyana, yemwe angabweretse molimba mtima malingaliro aukadaulo, otsogola kuti athe kuthana ndi ntchito zingapo zofunika, zovuta, ndi matekinoloje.
Ngati muli ndi mafunso kapena mafunso, omasuka kulankhula nawosales@pcbfuture.com, tikuyankhani ASAP.
