Kufunika kwa Automation-ready Solderless Interconnects
Kupanga njira zolumikizirana pa-board ndi gawo lovuta kwambiri pakukhazikitsa njira zowotchera zopanda lead.Gawo limodzi lofunikira kwa opanga ma voliyumu ambiri ndikusunga magwiridwe antchito onse.Njira zachiwiri zogulitsira zomwe zakhala zikufunidwa mwamwambo pakulumikiza zolumikizira zazikulu ndi zolumikizira zina zapadera ndizovuta kwambiri kuzisintha kukhala zopanda lead.Izi ndizovuta makamaka kwa PCB zamkuwa zolemera monga zolumikizira mphamvu.
Zikhomo za Press-fit (zogwirizana) zakhala zikuchitika kwa zaka zopitilira 20, zomwe zimagwiritsidwa ntchito kwambiri m'misika ingapo yomwe akuyembekezeredwa.Tekinoloje ya Press-fit (yogwirizana) imaphatikizapo mapangidwe apadera a gawo loyikapo la pini iliyonse, yomwe imapereka mawonekedwe olimba komanso odalirika a gasi omwe ali ndi dzenje lodzaza ndi dzenje ndipo safuna sitepe yotsatizana.
Gawo lolowetsamo la pini ndilokulirapo kuposa kukula kwa dzenje koma limapangidwa kuti liwonongeke poikapo, zomwe zimapanga kukangana kwamphamvu pakati pa pini ndi malo opukutidwa.
Diso-la-singano Design
Kwa zaka zambiri, njira zingapo zopangira zida zakhala zikugwiritsidwa ntchito kuti apereke chiwongola dzanja chofunikira pamapini ovomerezeka.Monga makina osindikizira (ogwirizana) amapita kuzinthu zatsopano monga Smart Junction Boxes, m'makampani oyendetsa galimoto, ndizofunikira kuti mphamvu pakati pa pini ndi malo opangidwa ndi mapulaneti akhalebe okwanira kuti athe kupirira zinthu zachilengedwe ndi makina monga kutentha, chinyezi, kugwedezeka, kugwedezeka ndi zinthu zina zolimba zomwe zimakhala mkati mwagalimoto.
Njira ya "diso-la-singano" yatsimikiziridwa kuti ikupereka teknoloji yodalirika kwambiri yowonjezeretsa mphamvu zonse zosungirako zoyamba komanso zopitirira.Mapangidwe a masika omwe amagwiritsidwa ntchito pokonzekera diso la singano amapereka mphamvu yolumikizana kwanthawi yayitali motsutsana ndi mbiya ya dzenje.
Kutentha kwa mapini onse ndi -40 mpaka 125 C, ndipo amatha kupirira 125 C kwa maola 1,008.Zikhomo zakumanja (mizere imodzi ndi iwiri) zimapezekanso kuti mujowine ma PCB a perpendicular.Zogulitsa zonse zimaperekedwa ndi RoHS-free plating.
Zolumikizira zimapangidwa ndi pulasitiki yolimba yokhala ndi zikhomo zambiri.Zitha kukhala ndi mapini ochepera atatu, komanso mapini 256.”: ikutero Assembly Magazine m’nkhani yake yonena za Press-fit connectors ndi ubwino wake.
Kuthekera Kwamakono
Malo osindikizira (ogwirizana) ali ndi mphamvu zamakono ndipo amatha kukhala othandiza kwambiri pamagetsi amphamvu pazitsulo zamkuwa zolemera kwambiri, zomwe zimakhala zovuta kugulitsa ndipo zimakhala zovuta kwambiri kusintha kukhala malo opanda lead.M'malo mongosintha kapena kusintha magawo a reflow kuti akwaniritse zovuta zapadera zogulitsira ma PCB amkuwa olemera, opanga amatha kukhazikitsa mazenera owongolera njira ndikuchotsa zofunikira zapadera zogulitsira pogwiritsa ntchito kulumikizana kogwirizana ndi mapulogalamu apamwamba.
Kuyesedwa Kudalirika, Mphamvu Zosungira & Kukaniza Zachilengedwe
Tekinoloje zamtundu wa diso-of-the-needle Press-fit (zogwirizana) zayesedwa kwambiri kuti zitsimikizire kuti zikutsatira zofunikira zingapo zamakampani, kuphatikiza SAE/USCAR-2, Rev4, EIA Publication 364 ndi IEC 60352-5.Njira yoyesera idagwiritsa ntchito kuwunika mwadongosolo kwachilengedwe, makina komanso kudalirika kwazinthu zomwe zimayendetsedwa.
Kuyesa kunachitika pamitundu yosiyanasiyana yolumikizirana ya Press-fit (yogwirizana) ndi mitundu ya PCB (kuphatikiza plating yamkuwa, plating yagolide ndi kumaliza kwa HASL).Zitsanzo zonse zoyeserera zidapangidwa ndikusonkhanitsidwa pogwiritsa ntchito njira zopangira zokhazikika komanso njira zabwino.
Kuyesa kwapadera kumaphatikizapo kugwedezeka, kugwedezeka kwamafuta & moyo wamafuta, kugwedezeka kwa makina, mphamvu yoyika, mphamvu yosungira, chinyezi, kupalasa njinga zamakono komanso kukana kulumikizana.Mapangidwe onse olumikizirana amadutsa mosawonongeka popanda kuwonongeka ndi/kapena kutsatana ndi magawo ena.
Zogwirizana ndi Pini, Zosintha, Zosankha
Zolumikizira za Press-fit (zogwirizana) zikupezeka pano pamasinthidwe awa:
Ma terminals osiyanasiyana (masamba, tabu, etc.)
Zikhomo zopitirira-reeled
Kanikizani mitu yokwanira pama reel osalekeza kapena kutalika koduliratu (m'modzi kapena awiri-by-by)
Square kapena kuzungulira (mafakitale muyezo kapena makonda ma diameter & kutalika kwa pini)
