Kusiyana pakati pa PCB ndi PCB msonkhano

PCBA ndi chiyani

PCBA ndiye chidule chamsonkhano wa komiti yadera wosindikizidwa.Zikutanthauza kuti, ma PCB opanda kanthu amadutsa njira yonse ya SMT ndi DIP plug-in.

SMT ndi DIP ndi njira zonse zophatikizira magawo pa bolodi la PCB.Kusiyana kwakukulu ndikuti SMT sifunikira kubowola mabowo pa bolodi la PCB.Mu DIP, muyenera kuyika PIN mu dzenje lobowola.

Kodi SMT (Surface Mounted Technology) ndi chiyani?

Surface Mounted Technology makamaka imagwiritsa ntchito makina okwera kukweza tizigawo tating'ono ta PCB board.Njira yopanga ndi: PCB board positioning, kusindikiza solder phala, phiri makina okwera, reflow ng'anjo ndi anamaliza anayendera.Ndi chitukuko cha sayansi ndi ukadaulo, SMT imathanso kuyika magawo akulu akulu, monga: zida zamakina zazikuluzikulu zitha kuyikidwa pa boardboard.

Msonkhano wa SMT PCBkuphatikiza kumakhudzidwa ndi malo ndi kukula kwa gawo.Komanso, khalidwe la solder phala ndi khalidwe kusindikiza amathandizanso kwambiri.

DIP ndi "plug-in", ndiko kuyika magawo pa bolodi la PCB.Chifukwa cha kukula kwa magawo ndi kwakukulu ndipo sikoyenera kukwera kapena pamene wopanga sangagwiritse ntchito teknoloji yosonkhanitsa SMT, ndipo plug-in imagwiritsidwa ntchito kugwirizanitsa zigawozo.Pakali pano, pali njira ziwiri kuzindikira pulagi Buku ndi loboti pulagi-mu makampani.Njira zazikulu zopangira ndi: kumata zomatira kumbuyo (kupewa kuyika malata pamalo omwe sayenera kukutidwa), pulagi, kuyang'ana, kutenthetsa, kupukuta mbale (kuchotsa madontho otsalira pakudutsa ng'anjo) ndikumaliza. kuyendera.

PCB ndi chiyani

PCB imatanthawuza bolodi losindikizidwa, lomwe limatchedwanso bolodi losindikizidwa.PCB ndi gawo lofunikira lamagetsi, komanso chithandizo chazigawo zamagetsi komanso chonyamulira cholumikizira zamagetsi zamagetsi zamagetsi.Chifukwa chopangidwa ndi makina osindikizira amagetsi, ndipo amatchedwa bolodi losindikizidwa.

Mukatha kugwiritsa ntchito PCB pazida zamagetsi, chifukwa cha kugwirizana kwa mtundu womwewo wa PCB, cholakwika cha wiring pamanja chimatha kupewedwa, ndipo zida zamagetsi zimatha kulowetsedwa kapena kuziyika, kuzigulitsa, kuzigulitsa, kuzizindikirika, kuti zitsimikizire mtundu wake. ya zida zamagetsi, ndikuwongolera zokolola za anthu ogwira ntchito, kuchepetsa mtengo ndikuthandizira kukonza.

PCB itha kugwiritsidwa ntchito kwambiri, chifukwa ili ndi zabwino zambiri zapadera:

1. Kuchulukana kwakukulu: Kwa zaka zambiri, kachulukidwe ka PCB kachulukidwe kakang'ono kangathe kukula ndikusintha kwa kuphatikiza kwa IC ndi ukadaulo woyika.
2. Kudalirika kwakukulu.Kupyolera mu kufufuza, kuyesa ndi kukalamba kuyesa, PCB ikhoza kugwira ntchito modalirika kwa nthawi yaitali (nthawi zambiri zaka 20).
3. ŸKupangidwe.Pakuti PCB ntchito zofunika (magetsi, thupi, mankhwala, makina, etc.), PCB mapangidwe akhoza anazindikira kudzera kamangidwe 4. Standardization, standardization, etc., ndi nthawi yochepa ndi mkulu dzuwa.
5. ŸKubereka.Ndi kasamalidwe kamakono, kukhazikika, kukula (kuchuluka), zodziwikiratu ndi kupanga zina zitha kuchitidwa kuti zitsimikizire kusasinthika kwazinthu.
6. ŸKukhazikika.Yakhazikitsa njira yoyesera yokwanira, miyezo yoyesera, zida zosiyanasiyana zoyesera ndi zida zodziwira ndikuzindikira kuyenerera kwazinthu za PCB ndi moyo wautumiki.
7. ŸKusonkhana.PCB mankhwala si yabwino kwa yokhazikika msonkhano wa zigawo zosiyanasiyana, komanso zodziwikiratu ndi yaikulu kupanga misa.Pa nthawi yomweyo, PCB ndi zigawo zosiyanasiyana msonkhano zigawo akhoza anasonkhana kupanga zigawo zikuluzikulu, machitidwe, ndipo ngakhale makina onse.
8. ŸKukhazikika.Zogulitsa za PCB ndi magawo osiyanasiyana amsonkhano amapangidwa ndikupangidwa molingana ndi miyezo, magawowa amakhazikitsidwanso.Choncho, dongosolo likalephera, likhoza kusinthidwa mwamsanga, mosavuta komanso mosavuta, ndipo dongosolo likhoza kubwezeretsedwanso mwamsanga.Inde, pali zitsanzo zambiri.Monga kupanga dongosolo miniaturization, opepuka, mkulu-liwiro chizindikiro kufala ndi zina zotero.

Kodi pali kusiyana kotani pakati pa PCB ndi PCBA

1. PCB amatanthauza bolodi dera, pamene PCBA amatanthauza msonkhano wa dera pulagi-mu, SMT ndondomeko.
2. Bolodi yomalizidwa ndi bolodi yopanda kanthu
3. PCB ndi bolodi losindikizidwa, lomwe limapangidwa ndi epoxy glass resin.Imagawidwa m'magulu 4, 6 ndi 8 molingana ndi magawo osiyanasiyana azizindikiro.Chofala kwambiri ndi 4 ndi 6-wosanjikiza 4. matabwa.Chip ndi zinthu zina zachigamba zimalumikizidwa ku PCB.
5. PCBA akhoza kumveka ngati bolodi yomalizidwa dera kuti pambuyo ndondomeko pa bolodi dera anamaliza ndipo akhoza kutchedwa PCBA.
6. PCBA=Bodi Losindikizidwa la Circuit + Msonkhano
7. The anabala PCBs kudutsa ndondomeko yonse ya SMT ndi kuviika pulagi-mu, amatchedwa PCBA mwachidule.

PCB ndiye chidule cha bolodi losindikizidwa.Nthawi zambiri amatchedwa dera losindikizidwa lomwe limapangidwa ndi dera losindikizidwa, zigawo zosindikizidwa kapena mawonekedwe opangira opangidwa ndi kuphatikiza bolodi losindikizidwa ndi bolodi losindikizidwa.Dongosolo la conductive lomwe limapereka kulumikizana kwamagetsi pakati pa zigawo zomwe zimateteza gawo lapansi zimatchedwa printed circuit.Mwanjira imeneyi, dera losindikizidwa kapena bolodi lomalizidwa la dera losindikizidwa limatchedwa bolodi losindikizidwa, lomwe limatchedwanso bolodi losindikizidwa kapena bolodi losindikizidwa.

Palibe magawo pa PCB yokhazikika, yomwe nthawi zambiri imatchedwa "printed wiring board (PWB)"

Kodi mukufuna kupeza turnkey yodalirikaWopanga msonkhano wa PCB?

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.
