Pamene Multi-Process Die Bonder Ikumveka Bwino

Makina olumikizirana osinthasintha amatha kukhala othandiza pamene fakitale ikugwiritsa ntchito zinthu zosiyanasiyana, ikupanga njira zopangira zinthu kapena ikufunika njira zingapo zolumikizirana mkati mwa pulatifomu imodzi.

Kutha kugwiritsa ntchito njira zambiri kumathandiza kwambiri pamene:

• Mitu ndi zida zomwe zayikidwa zimaphimba gawo lofunikira la die.

• Makinawa amatha kusintha pakati pa mitundu yofunikira ya zinthu zolowera.

• Ma module operekera, kuponda, kutentha ndi mpweya amapezeka.

• Mapulogalamu ndi maphikidwe amathandizira kusintha kwa njira zolamulidwa.

• Zotsatira zomwe zikuyembekezeredwa zimakhala zothandiza pambuyo pa kusintha kwa zinthu.

• Kukonza ndi kukonza zinthu kungayendetsedwe m'njira zosiyanasiyana.

Makina odzipereka okhala ndi voliyumu yambiri angakhale oyenera kwambiri pamene gulu limodzi la zinthu likutsogolera pakupanga ndipo limafuna njira yapadera yogwirira ntchito ndi leadframe, kulamulira kofewa kwa solder kapena kukonzekera mwamphamvu kwambiri.

Mafunso Ofunsidwa Kawirikawiri Okhudza Kusankha Makina Olumikizira Die Bonding

Kodi makina olumikizirana a die imodzi amatha kuyendetsa njira za epoxy ndi eutectic?

Mapulatifomu ena osinthasintha amatha kuthandizira zonse ziwiri, koma pokhapokha ngati chotulutsira chofunikira, makina otenthetsera, chowongolera mpweya, zida ndi mapulogalamu ayikidwa. Dzina la chitsanzo lokha silitsimikizira kuthekera kwa njira zambiri.

Kodi sintering ya siliva imamalizidwa kwathunthu mkati mwa bond yofa?

Osati nthawi zonse. Cholumikizira cha die chingagwiritse ntchito zinthu, kuyika die ndikuchita ma tacking, pomwe sintering yomaliza imachitika mu njira yosiyana yopanikizika kapena yopanda kupanikizika. Mzere wonse uyenera kuwunikidwanso.

Kodi mgwirizano wa eutectic ndi wofanana ndi wofewa wosweka die attach?

Ayi. Zonse ziwiri zimagwiritsa ntchito zinthu zomangira zitsulo komanso kutentha, koma kagwiridwe kake ka aloyi, mawonekedwe ake, mlengalenga, zida zopangira ndi zida zopangira zimatha kusiyana. Njira yofunikira iyenera kufotokozedwa ndi phukusi ndi dongosolo la zinthuzo.

Kodi kulondola kwambiri kwa malo kumatanthauza makina abwino olumikizirana ndi kufa?

Osati kokha. Kulondola kuyenera kuganiziridwa pamodzi ndi kusamalira die, kuwongolera chingwe cha bond, kugwiritsa ntchito zinthu, mphamvu, kutentha, automation ndi mikhalidwe yeniyeni yoyezera.

Ndi mfundo ziti zomwe ziyenera kukonzedwa musanapemphe upangiri wa die bond?

Konzani miyeso ndi makulidwe a die, mtundu wa zolowetsa, substrate, zinthu zomangira, zofunikira pakuyika, mphamvu ya bond, kutentha, mlengalenga, cholinga chopangira ndi ntchito zofunika zowunikira kapena kutsatira.

Malangizo Omaliza

Makina olumikizirana ndi die ayenera kusankhidwa ndi cholumikizira chomwe ayenera kupanga, osati kokha ndi liwiro lake, kulondola kwake kapena dzina la chitsanzo. Njira zolumikizirana ndi epoxy zimadalira kwambiri kuyika ndi kuchiritsa kwa zinthu. Njira zolumikizirana ndi zofewa zimafuna mikhalidwe yolamulira yolumikizirana ndi zitsulo. Kusakaniza kwa siliva kumafuna kukonzekera bwino kwa zinthu, kulumikiza ndi njira yonse yolumikizirana.

Ndemanga ikupezekamakina olumikizirana ndi diePambuyo pa ndondomekoyi, njira yoyendetsera zinthu ndi ma module ofunikira amafotokozedwa. Kuti mukambirane za polojekiti, tumizani die, substrate, zinthu zomangira, cholinga chopangira ndi njira yomwe mukufuna kudzera muTsamba lofufuza za zida zonse za SMT.
