Nkhani - Kukhazikitsa Press-fit Pin Technology mu Njira Zomwe Zilipo Zokha

Ngakhale kusanakhale kodetsa nkhawa kopanda kutsogolera, ntchito zachiwiri za soldering zabweretsa zovuta.

Kupeza zokolola zambiri komanso kuphatikiza ma voliyumu poyika ma terminals a solder sikunali kotheka nthawi zonse.Izi ndizofunikira makamaka m'makampani opanga magalimoto, pomwe zolumikizira zazikulu zowumbidwa zimagwiritsidwa ntchito mobwerezabwereza pazizindikiro zamphamvu komanso zowongolera.Opanga amayenera kuphatikizira zolumikizira zodziwikiratu zokha pomwe akuchepetsa zovuta zokhudzana ndi njira zogulitsira.Kuti akwaniritse cholinga ichi, ukadaulo wolumikizira makina umalola kuyika kwa makina othamanga kwambiri a pini limodzi kapena angapo ogwirizana ndi ma terminals omwe safuna masitepe otsatirawa ndikuwonjezera mphamvu yosungira.

Tekinoloje ya Press-fit, yomwe imadziwikanso kuti interference fit or friction fit, yatsimikiziridwa ndipo imagwiritsidwa ntchito kwambiri pamakampani amagalimoto ndi matelefoni.Nthawi zambiri, izo zathetsa soldering kwa pin-intensive interconnect systems.Ikukula mosalekeza kuti ikwaniritse zovuta zopanga zatsopano ndikuthana ndi zinthu zambiri zofunika.

Vuto lalikulu limakhudza kulinganiza koyenera pakati pa mphamvu yoyikapo yomwe ikufunika ndi kuchuluka kwa kusungitsa (mwachitsanzo, mphamvu yochotsa yomwe imafunikira pochotsa pini).Mphamvu yosungira iyenera kukhala pafupi kwambiri ndi mphamvu yoyikapo kuti ikhale yolimba kwambiri yolumikizira.Kupindika kwambiri kwa gawo lofikira atolankhani kumatha kupangitsa kuti mphamvu yanthawi zonse ikhale yocheperako pakati pa pini yogwirizana ndi mbiya ya dzenje.Zimachepetsa mphamvu yosungira ndi ntchito pa moyo wa mankhwala.

Gas Tight Fit yokhala ndi Kusunga Kwambiri

YICHUAN imapereka mayankho omveka bwino omwe amapatsa makasitomala athu maulumikizidwe osagulitsa, amphamvu mkati, opanda mpweya.Mapini athu ogwirizana ndi makina osindikizira adayesedwa bwino pamiyezo yonse yamakampani.Kukangana kwa pini ya press-fit kumapereka kulumikizana kolimba kwa gasi ndi mphamvu yosunga yokwanira.Imasunga mphamvu yokhazikika pamabowo (PTH) a bolodi losindikizidwa, ndikuchotsa kufunikira kwa soldering.Pambuyo poyika pini yogwirizana, kulumikizako kumatsirizidwa m'njira yabwino kwambiri

Pamene gawo la diso la singano la pini ya press-fit limatenga mapindikidwe a friction fit ndipo silimapundula pokutidwa ndi dzenje.Ichi ndichifukwa chake ndizotheka kuchotsa pini yosindikizira pambuyo pake popanda kuwonongeka kwa PCB kapena kufunikira kwa kukonzanso kwakukulu.N'zotheka kuchotsa zikhomo zowonongeka zowonongeka mothandizidwa ndi chida chosavuta chamanja.Zimalola kuyika pini yatsopano mu wakale wokutidwa ndi dzenje.

Kupitilira pakupanga kwaukadaulo wa fine-pitch surface mount technology (SMT) kumapangidwanso kukhala kosavuta pogwiritsa ntchito ukadaulo wa pini ya press-fit.Pamene kusiyana pakati pa maulumikizidwe kukucheperachepera, zovuta za soldering zimakula kwambiri.Njira yonseyi iyenera kuyendetsedwa mwamphamvu.Kuyika kwa solder phala kuyenera kuchitidwa molimba kwambiri kuti musatseke mlatho kapena kuwotcha pakati pa mapepala.Izi ndizofunika kuchepetsa mikangano ya solder ndi SMT ndi zolumikizira za pini-in-paste.Nthawi zambiri amafunikira ma solder fillets kuti atsimikizire kulimba kwa mphamvu zolumikizirana zakunja.Mapini ogwirizana ndi makina osindikizira amalola wopanga kuti athetse zovuta, zida zapadera ndi ndalama zowonjezera zomwe zimagwirizanitsidwa ndi zolumikizira zolumikizira pama board ang'onoang'ono a SMT.

Zapangidwa ndi Kupakidwa Kuti Zithandizire Njira Yopangira Ma Automation

Mapini onse osindikizira amaperekedwa m'njira zopindika mosalekeza ngati zolumikizira pawokha kapena zingapo kuti zilowedwe ndi makina oyika mapini othamanga kwambiri.Izi zimathandizira ukadaulo wolumikizira atolankhani kuti uphatikizidwe bwino mkati mwa SMT iliyonse yomwe ilipo kapena mizere yamabowo.Ma pini a Press-fit amatha kulowetsedwa ngati zolumikizirana pamtundu uliwonse wofunikira, kapena kuikidwa ngati zolumikizira pamutu wa pini, kutsata kutalika kofunikira ndi/kapena kuwerengera malo.Kutengera ndi zomwe mukufuna kugwiritsa ntchito, mitu ya pini yokwanira yosindikizira imapezeka ngati imodzi (1 x 1, 1 x 2, ndi zina) kapena ziwiri-by (2 x 2, 2 x 3, etc.) masinthidwe.

Chifukwa cholumikizira cholumikizira chosindikizira chokwanira chamalizidwa mu sitepe imodzi, ntchito yoyika yokha imatha kuphatikizidwa pafupifupi nthawi iliyonse pakupanga konse.Kawirikawiri, sitepe yolowetsa pini yosindikizira imachitika kumapeto kapena pafupi ndi mapeto a ndondomekoyi;pambuyo pa zigawo zonse za SMT zayikidwa kale ndikugulitsidwanso.

Kugwiritsa ntchito ukadaulo wa solderless press-fit for on-board interconnects amalola njira zonse za SMT (zowonera phala la solder, kuyika kwa gawo lapamwamba ndi pansi, kutulutsanso, ndi zina zambiri) kuti zichitike popanda kulumikizana kolumikizana.Izi zimachepetsa mtengo ndi zovuta zophatikizira njira zovuta monga kuyika kwa mawonekedwe osamvetseka kwa zolumikizira, kukanikiza ndi phala, kugulitsa kwachiwiri ndi/kapena njira zamabuku.Kusintha ma solder ndi ukadaulo wa press-fit kudzapititsa patsogolo ma automation ndi mabizinesi.

Kuphatikiza pa kufewetsa kutulutsa kwazinthu zonse, kuyika ma solderless interconnects monga gawo lomaliza kumapewanso chiopsezo cha zidutswa ndi ndalama zogwirira ntchito zomwe zingachitike poyesa kuyendetsa njira zovuta za soldering kumtunda.Njira zina zonse zogwirira ntchito zamalizidwa kale ndipo, pakuyika mapini kapena ma terminals, msonkhano womaliza wachitika ndikukonzekera kuyesa.

YICHUAN imapereka makina oyika mapini othamanga kwambiri m'misika yosiyanasiyana ku North America, Europe ndi Asia.
