Musiyano pakati pePCB nePCB gungano

Chii chinonzi PCBA

PCBA ndiyo chidimbu chegungano rebhodhi redunhu rakadhindwa.Zvinoreva kuti, maPCB asina chinhu anoenda kuburikidza nemaitiro ese eSMT uye DIP plug-in.

SMT neDIP inzira dzese dzekubatanidza zvikamu paPCB board.Musiyano mukuru ndewekuti SMT haidi kuchera maburi paPCB board.MuDIP, unofanirwa kuisa PIN mugomba rakacherwa.

Chii chinonzi SMT (Surface Mounted Technology)

Surface Mounted Tekinoroji inonyanya kushandisa muchina wekukwira kukwira mamwe madiki madiki kuPCB board.Maitiro ekugadzira ndeaya: PCB bhodhi yekumisikidza, kudhinda solder paste, gomo muchina wakaiswa, reflow choto uye kupera kuongorora.Nekuvandudzwa kwesainzi uye tekinoroji, SMT inogona zvakare kukwira mamwe mahombe-saizi zvikamu, senge: mamwe mahombe-mahombe mameshini zvikamu zvinogona kuisirwa pabhodhi reamai.

SMT PCB musanganokubatanidzwa kunonzwa kune chinzvimbo uye chikamu saizi.Mukuwedzera, kunaka kwe solder paste uye kudhinda mhando inoitawo basa rinokosha.

DIP i "plug-in", kureva kuisa zvikamu paPCB board.Nekuda kwehukuru hwezvikamu zvakakura uye hazvina kukodzera kukwirisa kana kana mugadziri asingakwanisi kushandisa SMT kuunganidza tekinoroji, uye plug-in inoshandiswa kubatanidza zvikamu.Parizvino, pane nzira mbiri dzekuziva iyo manual plug-in uye robhoti plug-in muindasitiri.Maitiro makuru ekugadzira ndeaya: kunamatira kumashure glue (kudzivirira tin plating kunzvimbo isingafanirwe kuputirwa), plug-in, kuongorora, wave soldering, plate brushing (kubvisa tsvina yakasara muchoto ichipfuura) uye yapera. kuongorora.

Chii chinonzi PCB

PCB zvinoreva bhodhi redunhu rakadhindwa, iro rinonziwo rakadhindwa wiring board.PCB chinhu chakakosha chemagetsi chikamu, zvakare tsigiro yezvikamu zvemagetsi uye mutakuri wemagetsi ekubatanidza zvinhu zvemagetsi.Nekuda kweiyo yakagadzirwa nemagetsi kudhinda, uye yakanzi yakadhindwa redunhu bhodhi.

Mushure mekushandisa PCB yemidziyo yemagetsi, nekuda kwekuenderana kwerudzi rumwe chete rwePCB, iyo wiring yekukanganisa inogona kudzivirirwa, uye zvinhu zvemagetsi zvinogona kuiswa otomatiki kana kunamirwa, zvotengeswa, uye zvinoonekwa otomatiki, kuitira kuti ive nechokwadi. yemidziyo yemagetsi, uye kuvandudza kugadzirwa kwevashandi, kuderedza mutengo uye kufambisa kugadzirisa.

PCB inogona kushandiswa zvakanyanya uye zvakanyanya, nekuti ine akawanda akasiyana mabhenefiti:

1. High density: Kwemakumi emakore, PCB yakakwirira density inogona kukura nekuvandudzwa kweIC yekubatanidza uye yekuisa tekinoroji.
2. Kuvimbika kwepamusoro.Kuburikidza nenhevedzano yekuongorora, bvunzo uye kuchembera bvunzo, PCB inogona kushanda yakavimbika kwenguva yakareba (kazhinji makore makumi maviri).
3. ŸDesignability.PaPCB performance performance (yemagetsi, yemuviri, makemikari, mechanical, etc.), PCB dhizaini inogona kuitika kuburikidza nedhizaini 4. Kumira, kumira, nezvimwewo, nenguva pfupi uye nekubudirira kwakanyanya.
5. Kubudirira.Ne manejimendi emazuva ano, kumira, chiyero (huwandu), otomatiki uye kumwe kugadzirwa kunogona kuitwa kuti ive nechokwadi chekuenderana kwemhando yechigadzirwa.
6. ŸTestability.Yakagadzirwa nzira yakakwana yekuyedza, zviyero zvekuyedza, akasiyana bvunzo zvishandiso uye zviridzwa zvekuona uye kuona PCB chigadzirwa chinokodzera uye hupenyu hwesevhisi.
7. Kuungana.Zvigadzirwa zvePCB hazvisi nyore chete kuungana kwakamisikidzwa kwezvikamu zvakasiyana, asiwo kune otomatiki uye hukuru-hukuru hukuru kugadzirwa.Panguva imwecheteyo, PCB uye zvikamu zvakasiyana-siyana zvegungano zvinogonawo kuunganidzwa kuti zvigadzire zvikamu zvakakura, masisitimu, uye kunyangwe muchina wese.
8. ŸKuchengetedza.Zvigadzirwa zvePCB uye zvikamu zvakasiyana-siyana zvegungano zvakagadzirirwa uye zvinogadzirwa zvinoenderana nezviyero, zvikamu izvi zvakare zvakamisikidzwa.Naizvozvo, kana sisitimu yakundikana, inogona kutsiviwa nekukurumidza, zviri nyore uye nyore, uye iyo system inogona kudzoserwa nekukurumidza.Zvechokwadi, kune mimwe mienzaniso.Zvakadai sekugadzira iyo miniaturization system, lightweight, high-speed signal transmission nezvimwe zvakadaro.

Ndeupi musiyano pakati pePCB nePCBA

1. PCB inoreva bhodhi redunhu, nepo PCBA ichireva gungano redunhu bhodhi plug-in, SMT maitiro.
2. Yakapedzwa bhodhi uye bhodhi risina chinhu
3. PCB yakadhindwa yedunhu bhodhi, iyo inogadzirwa ne epoxy glass resin.Iyo yakakamurwa kuita 4, 6 uye 8 mitsara zvichienderana neakasiyana masignal layer.Inonyanya kuzivikanwa ndeye 4 uye 6-layer 4. mapuranga.Chip uye zvimwe zvigamba zvinhu zvakabatanidzwa kuPCB.
5. PCBA inogona kunzwisiswa seyakapedza redunhu bhodhi iri mushure mekuita pabhodhi redunhu rapera uye rinogona kunzi PCBA.
6. PCBA=Yakadhindwa Circuit Board +Assembly
7. MaPCB akashama anopinda muhurongwa hwese hweSMT uye dip plug-in, inonzi PCBA kwenguva pfupi.

PCB ndiyo chidimbu chebhodhi rakadhindwa redunhu.Inowanzonzi yakadhindwa redunhu iyo inogadzirwa neyakadhindwa yedunhu, yakadhindwa zvikamu kana iyo conductive pateni inoumbwa nekubatanidzwa kweakadhindwa redunhu bhodhi uye rakadhindwa redunhu bhodhi.Iyo conductive pateni inopa kubatana kwemagetsi pakati pezvikamu pane insulating substrate inonzi printed circuit.Nenzira iyi, dunhu rakadhindwa kana bhodhi rakapedzwa redunhu rakadhindwa rinonzi rakadhindwa redunhu bhodhi, rinonziwo rakadhindwa redunhu bhodhi kana rakadhindwa redunhu bhodhi.

Iko hakuna zvikamu paPCB yakajairwa, inowanzonzi "printed wiring board (PWB)"

Unoda here kuwana yakavimbika turnkeyPCB musangano mugadziri?

Chinangwa chePCBFuture ndechekupa indasitiri neyakavimbika yepamusoro PCB yekugadzira uye masevhisi egungano kubva kune prototype kusvika pakugadzirwa nenzira inodhura.Chinangwa chedu ndechekubatsira mushandisi wega wega kuti ave akanyatso kutenderedzwa, murapi wemarudzi akawanda anogona kuunza nechivimbo hunyanzvi, hwekucheka-kumucheto mainjiniya mazano kuti atakure chero nhamba yemabasa akakodzera, matambudziko, uye matekinoroji.

Kana uine chero mibvunzo kana kubvunza, inzwa wakasununguka kutibatasales@pcbfuture.com, tichakupindura iwe ASAP.
