Immersion Gold Multilayer PCB Printed Circuit Board yokhala ndi SMT ndi DIP

Zambiri Zamalonda

Zambiri Zogwirizana

1.SMT ndi chimodzi mwazinthu zofunikira pazigawo zamagetsi zamagetsi.Imatchedwa teknoloji yokwera pamwamba (kapena teknoloji yokwera pamwamba).Imagawidwa kukhala yopanda ma lead kapena njira zazifupi.Ndi msonkhano wadera umene umapangidwa ndi reflow soldering kapena dip soldering.Tekinoloje ndiyonso ukadaulo wodziwika bwino komanso njira mumakampani opanga zamagetsi.
Mawonekedwe: Magawo athu atha kugwiritsidwa ntchito popangira magetsi, kutumiza ma siginecha, kutulutsa kutentha, komanso kukonza mawonekedwe.
Mawonekedwe: Imatha kupirira kutentha ndi nthawi ya machiritso ndi soldering.
Kusalala kumakwaniritsa zofunikira pakupanga.
Oyenera ntchito rework.
Zoyenera kupanga gawo lapansi.
Chiwerengero chochepa cha dielectric komanso kukana kwambiri.
Zida zomwe zimagwiritsidwa ntchito kwambiri pazogulitsa zathu ndizathanzi komanso zachilengedwe zokometsera ma epoxy resins ndi ma phenolic resins, omwe ali ndi zinthu zabwino zoletsa moto, kutentha, makina ndi dielectric, komanso mtengo wotsika.
Zomwe tatchulazi ndikuti gawo lapansi lolimba ndi lolimba.
Zogulitsa zathu zilinso ndi magawo osinthika, omwe amatha kugwiritsidwa ntchito kusunga malo, pindani kapena kutembenuza, kusuntha, ndipo amapangidwa ndi mapepala owonda kwambiri otchingira okhala ndi magwiridwe antchito apamwamba kwambiri.
Choyipa chake ndikuti njira yolumikizirana ndiyovuta, ndipo siyoyenera kugwiritsa ntchito ma micro-pitch application.
Ndikuganiza kuti mawonekedwe a gawo lapansi ndi otsogola ang'onoang'ono ndi malo otalikirana, makulidwe akulu ndi malo, kukhathamiritsa kwabwino kwamafuta, makina olimba, komanso kukhazikika bwino.Ndikuganiza kuti ukadaulo woyika pa gawo lapansi ndi ntchito yamagetsi, pali kudalirika, magawo okhazikika.
Sitingokhala ndi ntchito zodziwikiratu komanso zophatikizika zokha, komanso tili ndi chitsimikizo chowirikiza cha kafukufuku wamanja ndi makina owerengera, komanso kuchuluka kwa zinthu zomwe zikuyenda bwino ndi 99.98%.
2.PCB ndizofunikira kwambiri zamagetsi zamagetsi, ndipo palibe.Nthawi zambiri, njira yoyendetsera yopangidwa ndi mabwalo osindikizidwa, zigawo zosindikizidwa kapena kuphatikiza ziwirizo pazida zotchingira molingana ndi kapangidwe kokonzedweratu zimatchedwa dera losindikizidwa.Mapangidwe a conductive omwe amapereka kugwirizana kwa magetsi pakati pa zigawo pa gawo lapansi lotetezera amatchedwa bolodi losindikizidwa (kapena bolodi losindikizidwa), lomwe ndi lofunika kwambiri pazigawo zamagetsi ndi chonyamulira chomwe chingathe kunyamula zigawo zikuluzikulu.
Ndikuganiza kuti nthawi zambiri timatsegula kiyibodi ya pakompyuta kuti tiwone filimu yofewa (yomwe imatsekereza gawo lapansi) yosindikizidwa ndi zoyera zasiliva (silver paste) ndi zithunzi zoyikapo.Chifukwa mawonekedwe amtunduwu amapezedwa ndi njira yosindikizira yosindikizira, timatcha bolodi losindikizidwa losinthika lasiliva losindikizidwa.The kusindikizidwa matabwa dera pa zosiyanasiyana mavabodi kompyuta, makadi zithunzi, makadi maukonde, modemu, makadi zokuzira mawu ndi zipangizo zapakhomo zimene timaona mu mzinda kompyuta ndi osiyana.
Zomwe zimagwiritsa ntchito zimapangidwa ndi pepala (nthawi zambiri limagwiritsidwa ntchito kumbali imodzi) kapena maziko a nsalu yagalasi (yomwe imagwiritsidwa ntchito ngati mbali ziwiri komanso zosanjikiza zambiri), pre-impregnated phenolic kapena epoxy resin, mbali imodzi kapena mbali zonse za pamwamba. Amakutidwa ndi zokutira zamkuwa kenako ndi laminated ndikuchiritsidwa.Mtundu woterewu wa board board wovala zamkuwa, timawutcha bolodi lolimba.Tikapanga bolodi losindikizidwa, timalitcha kuti bolodi losindikizidwa lokhazikika.
A gulu losindikizidwa dera ndi kusindikizidwa dera chitsanzo mbali imodzi amatchedwa single-mbali yosindikizidwa dera bolodi, kusindikizidwa dera bolodi ndi kusindikizidwa dera chitsanzo mbali zonse, ndi kusindikizidwa dera bolodi wopangidwa ndi iwiri mbali interconnection kudzera zitsulo. mabowo, timatcha bolodi la mbali ziwiri.Ngati bolodi losindikizidwa lokhala ndi mbali ziwiri zamkati zamkati, zosanjikiza ziwiri zakunja, kapena ziwiri zamkati zamkati ndi ziwiri zakunja zakunja zimagwiritsidwa ntchito, mawonekedwe oyika ndi zomangira zomangira zimasinthidwa pamodzi ndi dera losindikizidwa. bolodi ndi chitsanzo conductive cholumikizidwa malinga ndi zofunika kamangidwe amakhala anayi wosanjikiza ndi zisanu wosanjikiza kusindikizidwa dera bolodi, amatchedwanso Mipikisano wosanjikiza kusindikizidwa dera bolodi.
3.PCBA ndi chimodzi mwa zigawo zikuluzikulu za zipangizo zamagetsi.PCB imadutsa munjira yonse yaukadaulo wapamtunda (SMT) ndikuyika mapulagi a DIP, omwe amatchedwa njira ya PCBA.M'malo mwake, ndi PCB yokhala ndi chidutswa cholumikizidwa.Limodzi ndi bolodi lomalizidwa ndipo linalo ndi bolodi lopanda kanthu.
PCBA ikhoza kumveka ngati bolodi yomalizidwa, ndiye kuti, njira zonse za board board zikamalizidwa, PCBA ikhoza kuwerengedwa.Chifukwa cha miniaturization mosalekeza ndi kuyengedwa kwa zinthu zamagetsi, matabwa ambiri amakono amamangiriridwa ndi etching resists (lamination kapena zokutira).Pambuyo powonekera ndi chitukuko, matabwa ozungulira amapangidwa ndi etching.
M'mbuyomu, kumvetsetsa kuyeretsa sikunali kokwanira chifukwa kachulukidwe ka PCBA kachulukidwe sikunali kokwera, komanso ankakhulupiriranso kuti zotsalira za flux sizinali za conductive komanso zabwino, ndipo sizingakhudze ntchito zamagetsi.
Misonkhano yamasiku ano yamagetsi imakhala yocheperako, ngakhale zida zing'onozing'ono, kapena mayendedwe ang'onoang'ono.Mapini ndi mapepala akuyandikira pafupi.Mipata yamasiku ano ikukhala yaying'ono komanso yaying'ono, ndipo zonyansa zimathanso kumangika mumipata, zomwe zikutanthauza kuti tinthu tating'onoting'ono, ngati tikhalabe pakati pa mipata iwiriyo, ingakhalenso Zoyipa zomwe zimachitika chifukwa chafupipafupi.
M'zaka zaposachedwa, makampani opanga zamagetsi akhala akudziwika kwambiri komanso amalankhula za kuyeretsa, osati pazofunikira zazinthu zokha, komanso pazofunikira zachilengedwe komanso kuteteza thanzi la anthu.Chifukwa chake, pali ambiri ogulitsa zida zoyeretsera ndi zothetsera, ndipo kuyeretsa kwakhalanso chimodzi mwazinthu zazikulu zakusinthana kwaukadaulo ndi zokambirana pamakampani opanga zamagetsi.
4. DIP ndi chimodzi mwa zigawo zikuluzikulu za zipangizo zamagetsi.Imatchedwa ukadaulo wapawiri wapaintaneti, womwe umatanthawuza tchipisi tating'onoting'ono tomwe timapakidwa pamizere iwiri.Fomu yoyikayi imagwiritsidwanso ntchito m'mabwalo ang'onoang'ono komanso apakatikati ophatikizika., chiwerengero cha zikhomo nthawi zambiri sichidutsa 100.
Chip cha CPU chaukadaulo wopaka ma DIP chili ndi mizere iwiri ya zikhomo, zomwe zimafunika kuyikidwa mu socket ya chip yokhala ndi DIP.
Inde, imathanso kulowetsedwa mwachindunji mu bolodi lozungulira ndi nambala yofanana ya mabowo a solder ndi makonzedwe a geometric kwa soldering.
Ukadaulo wapaketi wa DIP uyenera kusamala kwambiri pakulowetsa ndi kutulutsa kuchokera pa socket ya chip kuti zisawonongeke zikhomo.
Zina ndi: Mipikisano wosanjikiza ceramic DIP DIP, single-wosanjikiza ceramic DIP DIP, lead chimango DIP (kuphatikiza galasi ceramic kusindikiza mtundu, pulasitiki ma CD kapangidwe mtundu, ceramic low kusungunuka galasi ma CD mtundu) ndi zina zotero.
DIP plug-in ndi cholumikizira pakupanga zamagetsi, pali ma plug-ins amanja, komanso mapulagi a makina a AI.Ikani zinthu zomwe zafotokozedwa pamalo omwe mwatchulidwa.Ma plug-ins amanja amayenera kudutsanso kugwedeza kwamagetsi kuzinthu zamagetsi zamagetsi pa bolodi.Pazigawo zomwe zayikidwa, ndikofunikira kuyang'ana ngati zayikidwa molakwika kapena zaphonya.
DIP pulagi-mu positi soldering ndi ndondomeko yofunika kwambiri mu processing wa pcba chigamba, ndi processing khalidwe lake mwachindunji zimakhudza ntchito ya pcba bolodi, kufunika kwake n'kofunika kwambiri.Ndiye post-soldering, chifukwa zigawo zina, malinga ndi zofooka za ndondomeko ndi zipangizo, sizingathe kugulitsidwa ndi makina opangira mafunde, ndipo zingatheke ndi manja okha.
Izi zikuwonetsanso kufunika kwa mapulagi a DIP muzinthu zamagetsi.Pokhapokha ndi kutchera khutu kuzinthu zambiri zomwe sizingathe kuzindikirika.
M'zigawo zinayi zazikuluzikulu zamagetsi, aliyense ali ndi ubwino wake, koma amathandizirana wina ndi mzake kuti apange mndandanda wa njira zopangira.Pokhapokha poyang'ana ubwino wa zinthu zomwe zimapangidwira zingatheke kuti ogwiritsa ntchito ambiri ndi makasitomala azindikire zolinga zathu.
