Zovala zathu zambiri zimakhala ndi mikanda yokongola pamanja
kusankha zinthu
Kusankha kwazinthu kumagwira ntchito yofunika kwambiri pakuchitika kwa warpage. Mapulasitiki osiyanasiyana amakhala ndi mawonekedwe ocheperako, omwe amatha kubweretsa kuziziritsa kosiyanasiyana komanso kupindika kotsatira. Zida zotsika kwambiri, monga nayiloni, zimakhala zosavuta kugwa. Kumvetsetsa mawonekedwe a kuchepa kwa zida zosiyanasiyana ndikofunikira kuti muchepetse zovuta za warpage.
Kapangidwe kagawo
Mapangidwe a gawo lopangidwa ndi chinthu china chofunika kwambiri pa warpage. Mapangidwe ena, monga magawo opyapyala, makoma atali osachirikizidwa, ngodya zakuthwa, kapena kusiyanasiyana kwa makulidwe a khoma, angayambitse kuziziritsa kosiyana ndi kupindika. Kuganizira mbali izi pa gawo la mapangidwe a gawo kungathandize kuchepetsa nkhani za warpage.
Njira magawo
Zomwe zimagwiritsidwa ntchito popanga jekeseni, kuphatikizapo kuthamanga kwa jekeseni, kuthamanga kwa jekeseni, kutentha kwa sungunula ndi kukakamiza, zingakhale ndi zotsatira zazikulu pa warpage. Kuthamanga kwa jekeseni komwe kumathamanga kwambiri kapena kusungunula kutentha kwambiri kungayambitse kuzizira kosiyana, zomwe zimatsogolera ku warpage. Kuwongolera magawowa kutengera zinthu zakuthupi ndi kapangidwe ka gawo ndikofunikira kuti muchepetse tsamba lankhondo.
mtima pansi
Gawo lozizirira la njira yopangira jakisoni ndiyofunikira kuti mupeze magawo okhazikika. Kuzizira kosakwanira kapena kosagwirizana kungayambitse nkhondo. Kugwiritsa ntchito njira zoziziritsira zoyenerera, nthawi zozizirira komanso zoziziritsa kukhosi zingathandize kukwaniritsa kuziziritsa kofananako komanso kuchepetsa kuthekera kwa nkhondo.
Kudziwa chomwe chimayambitsa warpage ndikofunikira kuti tipeze yankho logwira mtima. Nazi njira zina zozindikiritsira ndi kuthetsa nkhani za warpage:
1. Kusanthula kwa nkhungu
Moldflow Analysis ndi chida chaumisiri chothandizidwa ndi makompyuta chomwe chimatengera njira yopangira jakisoni. Imalola opanga kuneneratu ndikuwona zovuta zomwe zingakhalepo panthawi ya mapangidwe. Pakuwunika kayendedwe kake, kudzaza mawonekedwe ndi kuziziritsa kwa pulasitiki wosungunuka, kusanthula kwa nkhungu kumathandizira kuzindikira madera omwe ali ndi vuto m'mapangidwe ena ndikupangira zosintha kuti muchepetse tsamba lankhondo.
2. Kukhathamiritsa kwa mapangidwe a nkhungu
Zoumba zokonzedwa bwino zimatha kuchepetsa kwambiri ma warpage. Kuwonjezera zinthu monga njira zoziziritsira, malo oyenerera pachipata ndi mpweya wabwino zingathandize kukwaniritsa ngakhale kuziziritsa ndi kuchepetsa warpage. Kugwiritsa ntchito njira zapamwamba zopangira nkhungu, monga kuziziritsa kofananira, kumatha kupititsa patsogolo kuziziritsa komanso kuchepetsa masamba ankhondo.
3. Njira kukhathamiritsa chizindikiro
Warpage ikhoza kuchepetsedwa pokonza magawo a ndondomeko potengera deta yoyesera ndi kusanthula kwa nkhungu. Kuwunika mwadongosolo kukakamiza kwa jakisoni, kuthamanga kwa jakisoni, kutentha kwasungunuka, ndikugwira kukakamiza kumatha kudziwa momwe mungachepetsere tsamba lankhondo. Njira zowunikira ndi kuwongolera njira, monga njira zowongolera zotsekera, zimathandizira kuti zinthu ziziyenda bwino ndikuchepetsa mwayi wankhondo.
4. Ukadaulo wopangidwa pambuyo poumba
Njira zopangira pambuyo pakupanga zitha kugwiritsidwanso ntchito kuthana ndi zovuta za warpage. Izi zikuphatikizapo njira monga annealing, kuchepetsa nkhawa, kapena kukonzanso pambuyo pa kuumba kwa gawolo. Annealing imaphatikizapo kuyika ziwalo zoumbidwa kuti ziziyenda mowotchera komanso kuziziritsa, zomwe zimathandiza kuthetsa kupsinjika kwamkati ndikuchepetsa kufalikira kwa nkhondo. Kukonza pambuyo pakupanga, monga kuwongola kutentha kapena kuwongola kwa laser, kumatha kukonzanso magawo okhotakhota kukhala miyeso yomwe ikuyembekezeka.
