IC chip kulephera kusanthula,ICChip Integrated mabwalo sangathe kupewa zolephera mu ndondomeko ya chitukuko, kupanga ndi ntchito.Ndi kusintha kwa zomwe anthu amafuna pazabwino komanso kudalirika kwazinthu, ntchito yosanthula kulephera ikukhala yofunika kwambiri.Kupyolera mu kusanthula kulephera kwa chip, IC chip ya opanga amatha kupeza zolakwika pamapangidwe, kusagwirizana kwa magawo aukadaulo, mapangidwe olakwika ndi magwiridwe antchito, ndi zina zambiri. Kufunika kwa kusanthula kulephera kumawonekera makamaka mu:
Mwatsatanetsatane, tanthauzo lalikulu laICkusanthula kulephera kwa chip kukuwonetsedwa m'magawo awa:
1. Kusanthula kulephera ndi njira yofunikira komanso njira yodziwira kulephera kwa tchipisi ta IC.
2. Kusanthula zolakwika kumapereka chidziwitso chofunikira pakuzindikira zolakwika.
3. Kusanthula kulephera kumapereka akatswiri opanga mapangidwe ndi kuwongolera kosalekeza ndi kuwongolera kamangidwe ka chip kuti akwaniritse zosowa zamapangidwe.
4. Kusanthula kulephera kungathe kuwunika momwe njira zosiyanasiyana zoyesera zimagwirira ntchito, kupereka zowonjezera zofunika pakuyesa kupanga, ndikupereka chidziwitso chofunikira pakukhathamiritsa ndi kutsimikizira njira yoyesera.
Njira zazikulu ndi zomwe zili mu kusanthula kulephera:
◆ Kutsegula dera lophatikizika: Pochotsa gawo lophatikizika, sungani umphumphu wa ntchito ya chip, sungani kufa, ma bondpads, ma bondwires komanso ngakhale chimango chotsogolera, ndikukonzekera kuyesa kusanthula kosavomerezeka kwa chip.
◆ SEM yowunikira galasi / EDX kusanthula kamangidwe: kusanthula kapangidwe kazinthu / kuwona zolakwika, kusanthula kwapang'onopang'ono kwa gawo la kapangidwe kazinthu, kuyeza kolondola kwa kukula kwake, ndi zina zambiri.
◆ Probe test: Chizindikiro chamagetsi mkati mwaICzitha kupezeka mwachangu komanso mosavuta kudzera muzofufuza zazing'ono.Laser: Micro-laser imagwiritsidwa ntchito kudula gawo lapamwamba la chip kapena waya.
◆ Kuzindikira kwa EMMI: EMMI yotsika kwambiri ya microscope ndi chida chapamwamba chowunikira zolakwika, chomwe chimapereka njira yowonongeka komanso yosawononga malo olakwika.Imatha kuzindikira ndikuyika luminescence yofooka kwambiri (yowoneka komanso pafupi ndi infrared) ndikujambula mafunde otuluka chifukwa cha zolakwika ndi zolakwika m'zigawo zosiyanasiyana.
◆OBIRCH application (mayeso osintha mtengo wa laser beam-induced impedance): OBIRCH nthawi zambiri imagwiritsidwa ntchito pakuwunika kwapamwamba komanso kutsika kwamkati mkati. ICchips, ndi mzere kutayikira njira kusanthula.Pogwiritsa ntchito njira ya OBIRCH, zolakwika m'mabwalo zimatha kupezeka bwino, monga mabowo m'mizere, mabowo pansi pa mabowo, ndi malo otsutsa kwambiri pansi pa mabowo.Zowonjezera zotsatila.
◆ Kuzindikira kwa malo otentha a LCD: Gwiritsani ntchito chophimba cha LCD kuti muwone makonzedwe a maselo ndi kukonzanso pamalo otayira a IC, ndikuwonetsa chithunzi chooneka ngati banga chosiyana ndi madera ena pansi pa microscope kuti mupeze malo otayira (cholakwika chachikulu kuposa 10mA) zomwe zingavutitse wopangayo pakuwunika kwenikweni.Fixed-point / non-fixed-point chip grinding: chotsani zitsulo zagolide zomwe zimayikidwa pa Pad ya chip driver LCD, kuti Pad isawonongeke, zomwe zimathandiza kusanthula ndi kubwezeretsanso.
◆ X-Ray kuyesa kosawononga: Dziwani zolakwika zosiyanasiyana mu ICkuyika kwa chip, monga kupukuta, kuphulika, voids, kukhulupirika kwa wiring, PCB ikhoza kukhala ndi zolakwika zina pakupanga, monga kusanja bwino kapena kutsekera mlatho, chigawo chotseguka, chigawo chachifupi kapena chosazolowereka Kuwonongeka kwa kugwirizana, kukhulupirika kwa mipira yogulitsa mu phukusi.
◆ SAM (SAT) akupanga chophophonya kuzindikira akhoza sanali destructively kuzindikira kapangidwe mkatiICchip phukusi, ndikuwona bwino kuwonongeka kosiyanasiyana komwe kumachitika chifukwa cha chinyezi ndi mphamvu zotentha, monga O wafer pamwamba delamination, O mipira yogulitsira, zopyapyala kapena zodzaza Pali mipata muzoyikamo, pores mkati mwazonyamula, mabowo osiyanasiyana monga malo omangira opindika. , mipira ya solder, fillers, etc.
