Anti-static ntsuas thiab cov tseev kom muaj
Kev tiv thaiv kev tiv thaiv zoo li qub rau cov khoom siv cog cog feem ntau yuav tsum ua raws li cov khoom siv hluav taws xob sib xyaw nrog kev siv hluav taws xob tsis zoo (ESD) qhov kev hnov mob tsis tsawg dua 2 qib. Yog tias cov khoom sib txuas nrog electrostatic paug (ESD) qhov kev paub ntawm Chav Kawm 1 yuav tsum tau siv, kev tiv thaiv Circuit Court yuav tsum tau muab tso rau theem qis tshaj plaws ntawm qhov ntsuas lossis cov cuab yeej, thiab qhov hluav taws xob electrostatic paug (ESD) yuav tsum tsis pub tsawg dua Chav 2.
Anti-static feem ntau yuav siv cov hauv qab no:
1. Txhua qhov kev tawm tswv yim sib txawv ua rau ntawm MOS cov twj yuav tsum tsis txhob nyob ua ke ntab. Nws yuav tsum txuas nrog lub hwj chim hauv av, lub zog (qhov chaw) Vss lossis fais fab (ntws) VDD nyob ntawm Circuit Court.
2. Txuas cov resistors hauv series nrog txhua lub tswv yim ntawm MOS ntaus ntawv.
3. Kev tsim tawm ntawm CMOS ntaus ntawv (tshwj tsis yog lub hloov hluav taws xob) tuaj yeem siv los cais txhua qhov tawm ntawm cov kab hluav taws xob txuas nrog lub thev naus laus zis thiab txuas lub vias mus rau Vss lossis VDD nrog ob txoj kev kub ceev hloov diodes.
4. Thaum siv cov tswv yim siv hluav taws xob ntev, yuav tsum tau siv lim lim dej.
5. Ntawm cov tswv yim ntawm kev tso hluav taws xob (electrostatic paug) (ESD) cov khoom sib xyaw bipolar, sab nraud RC network muaj cov khoom tiv thaiv nrog tus nqi tiv thaiv loj thiab cov capacitor uas muaj lub peev xwm tsis pub tsawg dua 100 pF txuas nrog sab nraud kom txo cov teebmeem ntawm electrostatic kev tso tawm (ESD). Thaum lub cim hluav taws xob hauv Circuit Court, ob lub diodes thaum uas tig mus kuj tseem siv tau los txiav lub 0,5V qhov hluav taws xob hla txhua qhov polarity los ua kom tsis txhob nkag tawm mus rau hauv av.
6. Tsis txhob txuas cov coj ntawm electrostatic tawm (ESD) rhiab Cheebtsam ntsia rau cov ntawv luam tawm Circuit Court ncaj qha mus rau lub tshuab hluav taws xob txuas mus txuas ntxiv tsis muaj thaiv hluav taws xob.
