Phukusi la BGA Underfill Epoxy
Kutentha Kwambiri
Kuyera Kwambiri
mavuto
Zamagetsi zamagetsi zakuthambo ndi kuyenda, magalimoto, magalimoto, kuyatsa kwakunja kwa LED, mphamvu za dzuwa ndi mabizinesi ankhondo omwe ali ndi zofunikira zodalirika kwambiri, zida zamagulu a solder mpira (BGA/CSP/WLP/POP) ndi zida zapadera pama board ozungulira zonse zimayang'anizana ndi ma microelectronics. Mchitidwe wa miniaturization, ndi ma PCB oonda okhala ndi makulidwe osakwana 1.0mm kapena magawo osakanikirana amisonkhano yamagulu akulu, zolumikizira zogulitsira pakati pa zida ndi magawo ang'onoang'ono zimakhala zosalimba chifukwa cha kupsinjika kwamakina ndi kutentha.
Solutions
Pakuyika kwa BGA, DeepMaterial imapereka njira yothetsera kudzaza - kutulutsa kwamphamvu kwa capillary. Chodzazacho chimagawidwa ndikugwiritsidwa ntchito pamphepete mwa chipangizo chosonkhanitsidwa, ndipo "capillary effect" yamadzimadzi imagwiritsidwa ntchito kuti guluu lilowe ndi kudzaza pansi pa chip, ndiyeno kutenthedwa kuti aphatikize chodzaza ndi chip substrate, olowa solder ndi PCB gawo lapansi.
Ubwino wa DeepMaterial underfill process
1. Kuchuluka kwa madzimadzi, kuyera kwakukulu, gawo limodzi, kudzaza mofulumira komanso kuchiritsa mofulumira kwa zigawo zomveka bwino kwambiri;
2. Ikhoza kupanga yunifolomu ndi yopanda kanthu pansi yodzaza pansi, yomwe imatha kuthetsa kupsinjika komwe kumachitika chifukwa cha kuwotcherera, kupititsa patsogolo kudalirika ndi makina a zigawozo, ndikupereka chitetezo chabwino cha mankhwala kuti asagwe, kupotoza, kugwedezeka, chinyezi. , ndi zina.
3. Dongosololi likhoza kukonzedwa, ndipo bolodi la dera likhoza kugwiritsidwanso ntchito, zomwe zimapulumutsa kwambiri ndalama.
Deepmaterial ndi otsika kutentha mankhwala bga flip Chip underfill pcb epoxy ndondomeko zomatira zakuthupi wopanga ndi kutentha zosagwira underfill ❖ kuyatira zinthu suppliers, kupereka chigawo chimodzi epoxy underfill mankhwala, epoxy underfill encapsulant, underfill encapsulation zipangizo flip chip mu pcpoxy electronic circuit board zochokera Chip underfill ndi chisononkho encapsulation zipangizo ndi zina zotero.
