Qhov cuam tshuam ntawm cov tshuab tso rau ntawm kev ua haujlwm zoo

Kev cuam tshuam rau kev tsim khoom
ATE programming txo cov khoom tsim tau vim tias lub sijhawm ntxiv ntxiv rau qhov kev pab cuam lub cuab yeej. Piv txwv li, yog tias yuav tsum muaj 15- qhov kev sim thib ob txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws, koj yuav tsum tau kuaj xyuas qhov tsis zoo. ATE ua haujlwm zoo li tus kws tshaj lij ib leeg-chaw nres nkoj kim heev. Ib yam li ntawd, rau cov khoom siv flash high-density thiab cov cuab yeej logic uas siv sijhawm ntev rau qhov kev pab cuam, tag nrho lub sijhawm sim yuav ntev dua, uas yog mob taub hau. Yog li ntawd, ATE programming yog tus nqi tsim nyog tshaj plaws thaum lub sijhawm programming tsawg heev piv rau tag nrho lub sijhawm kuaj xyuas. Txhawm rau txhim kho cov khoom tsim tau thiab txo lub sijhawm ua haujlwm ntev, ATE programming thev naus laus zis tuaj yeem ua ke nrog cov thev naus laus zis thev naus laus zis, xws li ciam teb scan lossis ib qho ntawm ntau txoj hauv kev patented.
Lwm qhov kev daws teeb meem yog qhov program tsuas yog khau raj ntawm lub hom phiaj ntaus ntawv thaum lub rooj tsavxwm raug sim. Tus so ntawm cov cuab yeej programming ua haujlwm yog ua thaum nws tsis cuam tshuam rau kev tsim khoom, feem ntau thaum lub cuab yeej ua haujlwm tau zoo. Txawm li cas los xij, tshwj tsis yog tias ATE muaj peev xwm dhau, qhov kev ua haujlwm muaj peev xwm ua tau txaus, thiab cov txheej txheem kev ua haujlwm tau zoo tshaj plaws rau cov khoom siv high-density yog ib qho khoom siv ua haujlwm. Piv txwv li: ProMaster 970 ntaus ntawv yog nruab nrog 12 interfaces thiab tuaj yeem ua haujlwm thiab laser cim 600 8-megabyte flash nco ib teev. Hauv qhov sib piv, ATE lossis tus neeg ntsuas kev ua haujlwm yuav siv sijhawm 60 txog 120 teev kom ua tiav cov haujlwm no.
Kev npaj siv kab ntau lawm
Raws li cov khoom siv hluav taws xob tau dhau los ua ntau thiab nyuaj thiab siab heev, qhov kev thov rau cov txheej txheem programmable nrog ntau lub zog thiab qhov ntom ntom kuj tseem nce ntxiv. Cov khoom siv qib siab no feem ntau xav tau lub sijhawm ua haujlwm ntev dua hauv OBP ib puag ncig, uas ncaj qha txo cov khoom lag luam ntawm cov khoom.
Ib yam li ntawd, lub sij hawm siv los ntawm cov programming cov khoom ntawm tib qhov ceev uas muab los ntawm cov khoom siv semiconductor sib txawv heev. Feem ntau hais lus, cov khoom siv nrog cov programming ceev tshaj plaws kuj tseem kim tshaj plaws. Yog li thaum txiav txim siab seb puas yuav them nyiaj ntau dua rau cov khoom siv nrog lub peev xwm ceev ceev, tib neeg ntsib qhov teeb meem ntawm kev tsim cov khoom lag luam thiab txo cov nqi khoom siv, lossis siv cov khoom pheej yig dua nrog lub sijhawm ua haujlwm qeeb thiab raug kev txom nyem los ntawm kev txo cov khoom lag luam.
Tsis tas li ntawd, cov neeg tsim khoom yuav tsum nco ntsoov tias lawv tsis tuaj yeem tso siab rau kev siv cov khoom siv semiconductor zoo tshaj plaws kom tau raws li qhov xav tau ntawm cov khoom loj uas tshwm sim hauv lub sijhawm luv luv. Qhov tsis muaj cov khoom siv zoo tshaj plaws yuav yuam cov tuam txhab lag luam rov xaiv lwm cov txheej txheem programming, txhua lub sijhawm sib txawv, tus nqi thiab muaj. Rau OBP, qhov xwm txheej no yog qhov nyuaj heev los ua kom tau txais cov kab ntau lawm.
Vim tias qhov programming tsis siv neeg muaj qhov zoo ntawm kev nrawm dua li cov kev daws teeb meem ib leeg-interface OBP, qhov cuam tshuam ntawm kev hloov pauv ntawm lub sijhawm programming tuaj yeem tsis quav ntsej kiag li. Ib yam li ntawd, vim tias cov kev daws teeb meem tsis siv neeg feem ntau txhawb nqa ntau txhiab yam khoom los ntawm cov neeg muag khoom sib txawv, cov teeb meem tshwm sim los ntawm kev siv cov khoom siv hloov pauv tuaj yeem daws tau.
Tus nqi PCB
Qhov kev thov rau kev ua haujlwm thiab kev sim ntawm PICs siab heev tau nce ntau heev. Qhov no yog vim cov neeg muab khoom siv nti siv cov thev naus laus zis silicon tshiab los tsim cov khoom siv nrog kev ceev thiab kev ua haujlwm siab tshaj plaws. Kev ua haujlwm zoo yuav tsum coj mus rau hauv tus account qhov ua tau zoo ntawm cov kab sib kis, teeb liab kab impedance, pin insertion, thiab cov yam ntxwv ntawm cov khoom. Yog tias tsis yog, teeb meem yuav tshwm sim ib zaug, suav nrog hauv av bounce, crosstalk, thiab teeb liab xav txog thaum lub programming.
Cov cuab yeej siv tshuab ua haujlwm zoo tshaj plaws tuaj yeem txo cov teeb meem no los ntawm kev tsim qauv zoo. Txhawm rau kom muaj peev xwm ua tau ATE programming, PCB tsim yuav tsum cuam tshuam nrog ib puag ncig circuits, capacitors, resistors, inductors, teeb liab crosstalk, Vcc thiab Gnd reflections, thiab pin-to-phaj fixtures. Tag nrho cov no yuav cuam tshuam zoo rau cov txiaj ntsig thiab kev ua haujlwm zoo. Vim tias qhov yuav tsum tau muaj ntau qhov chaw ntawm lub rooj tsavxwm, nrog rau qhov xav tau ntawm cov khoom sib cais (lugs, FETs, capacitors) thiab muaj peev xwm ua kom muaj zog, tus nqi ntawm PCB thaum kawg tau nce. Txawm hais tias txhua lub rooj tsavxwm sib txawv, tus nqi ntawm PCB feem ntau yuav nce 2% mus rau 10%.
