ESD kev nyab xeeb ntawm cov chaw ua haujlwm yuav tsum muaj
Yuav siv tsis tau rau hauv kev nrog hluav taws xob tiv thaiv av (vim xob laim)
Hauv av ua haujlwm yuav ntsuas nrog kev sib npaug ntawm lub siab tawv tester
1. Kev cobphum rau hauv kev cobphum Ua haujlwm: Nws muaj cov worktable, lub rooj npau npau tawv tiv thaiv, lub pluaj hlua khawm, thiab kab hluavtaws.
2. Yuav tsum muaj ntau tshaj ob lub nraub qaum ntawm lub ntsej muag ntawm lub rooj sib npaug tiv thaiv qub, ib qho rau tus neeg teb xov tooj thiab ib qho rau cov kws kho mob thiab cov kws ntsuam xyuas.
3, tsis pub siv lub thawv rau sab nraud hluav taws xob, hnab roj hmab, thawv iav, iav thiab lwm yam paug qis dua, cov ntaub ntawv yuav tsum tau muab tso rau hauv hnab yas tiv thaiv.
4. Kev tawm ntawm cov neeg sab nrauv (ESDwrist plab): Cov neeg uas hu ncaj nraim rau cov cuab yeej cuab tam uas yuav tsum tau hnav yuav tsum tau hnav ib lub tsho tiv thaiv zoo li qub. Lub dab teg pluaj yuav tsum muaj kev sib cuag nrog tib neeg tawv nqaij. Tus tsis muaj zog ntawm lub dab tawm lub xub pwg mus rau hauv av yuav tsum yog 1 MΩ.
5, ESD lub thawv: ntau qhov chaw ntawm cov cheebtsam uas muaj cov hnab, cov ciaj ciam, cov PCB racks, etc. yuav tsum muaj kev tiv thaiv electrostatic, tsis txhob cia siv cov hlau thiab cov thawv ntim, txhua lub ntim yuav tsum tau grounded.
6, cov neeg ua haujlwm hauv cov chaw ua haujlwm hauv qhov chaw ua haujlwm thiab kev tiv tauj nrog cov neeg ua haujlwm SMD cov khoom ua haujlwm yuav tsum hnav cov khoom qub, tshwj xeeb tshaj yog nyob rau ntawm qhov av qis tshaj ntawm 50% ntawm lub chaw qhuav (xws li caij ntuj no). Cov ntaub pua plag tsis sib xws yuav tsum ua raws li cov kev cai hauv lub tebchaws.
7. Cov neeg nkag mus rau hauv thaj chaw ua haujlwm yuav tsum hnav cov haujlwm ua haujlwm ua haujlwm tsis muaj zog. Cov neeg uas hnav cov khau uas niaj hnub siv yuav tsum siv cov khau thaiv kab mob, khau tiv thaiv los yog khawm pob tw.
8. Kev siv txoj hlua thiab tsav tsheb uas siv hauv cov kab ntau lawm yuav tsum tau nruab nrog cov av nplaum thiab cov av hauv av.
9. Ionising cua txias tshem tawm tau siv nyob rau ntawm cov khoom siv thauj khoom siv.
10. Lub rooj sib dhos sib dhos, kev sib tw, cov cuab yeej siv vuam, thiab ntau yam khoom siv uas siv rau hauv qhov chaw yuav tsum tau muab nrog lub xov zoo grounding. 11. Cov kev ntsuas kev tiv thaiv los ntawm kev sib tw (static test static test) yuav tsum muab ntsia rau ntawm qhov nkag mus rau qhov chaw tsim khoom. Txhua tus neeg nkag mus rau hauv qhov chaw tsim nyog yuav tsum ua kev sim tshuaj los tiv thaiv ua ntej nkag mus rau qhov chaw.
Kev tswj tus kheej muaj peev xwm hais txog cov lus qhia nram qab no:
(1) Tswj tswj hluav taws xob ib puag ncig lub zog:
a. Humidity tswj. Tsis txhob nce cov av ntub kom ntau li ntau tau yam tsis tau ua kom tawg los yog lwm yam kev puas tsuaj rau cov khoom lossis khoom muag;
b. Kub tswj. Txo qhov ntsuas kub kom ntau li ntau tau, nrog rau kev kub ntxhov thiab qhov khoom tiv thaiv kub li cas;
c. Plua plav tswj. Qhov no yog ib qho tseem ceeb ntawm kev tiv thaiv kev ua tawm (adsorption) ntawm hluav taws xob;
d. Floors, ntxhuav thiab cov rooj zaum cov ntaub thiab cov ntsig txog cov khoom ua haujlwm yuav tsum yog cov khoom siv los tiv thaiv thiab zoo grounded;
e. Electrostatic tiv thaiv kev ntsuas yuav tsum tau muab rau kev xa thiab cia cov khoom siv hluav taws xob, thiab kev ntim khoom thiab cov khoom ntim tawm;
f. Kev txau, ntws, kev xaav, kev sib tw thiab kev sib tw yuav tsum tau tswj nyob rau hauv cov kav dej ntawm cov khoom siv xws li kua thiab hmoov.
Siv tus saibxyuas.
(2) Tiv thaiv lub cev kom txhob raug them:
a. Hnav ib qho hlua khau tiv thaiv kab mob npog;
b. Hnav cov ris-tsho, cov ris-tsho, thiab lub kaus mom;
c. hnav cov khau los tiv thaiv thiab thom khwm, hnav ris tsho;
d. Hnav cov hnab looj tes tsis zoo thiab cov ntiv tes ntiv tes;
e. Txwv tsis pub txwv kev ua dej num rau tib neeg uas tsis ua hauj lwm (xws li ua qoj ib ce, ua phem, ua plaub hau, noj mov, thiab lwm yam);
f. Ua ib qho ionizing cua da dej.
(3) Kev Tswj Xyuas Cov Kev Tswj Txheej Txheem:
a. Tsim thiab siv cov txheej txheem khiav lag luam ntawm kev lag luam;
b. Siv cov khoom tig los tiv thaiv, tsheb thauj khoom, thawv ntawv, thawv ntawv thiab lwm cov thawv, khoom sib;
c. Siv cov cuab yeej siv los tiv thaiv (hlau, tin, thiab lwm yam)
d. Siv cov thawv ntim khoom tiv thaiv;
e. Teem lub sij hawm tsim nyog rau cov sij hawm rau cov khoom siv kua muaj zog ntsig txog thiab muaj plhom heev;
f. Txo qhov kev sib cuag, lub sijhawm, thaj chaw ntawm cov khoom (xws li daim ntaub, daim ntawv hlau, xaim, ntaub ntawv, ntaub xev, thiab lwm yam), cov ntawv tho txawv, cov ntawv xov xwm, cov khoom qub, thiab cov khoom) thiab txo qhov kev khiav hauj lwm.
Ntau qhov chaw ua haujlwm ntawm kev ua haujlwm zoo li qub:
1. Lub lag luam ntawm tag nrho cov khoom tsim nyog yuav tsum tau ua nyob rau hauv lub tshuab hluav taws xob hauv kev tuav pov hwm electrostatic. Tag nrho cov khoom uas nkag mus rau hauv thaj chaw ua hauj lwm tiv thaiv yuav tsum raug kho raws li qhov yuav tsum tau ua ntawm hluav taws xob tiv thaiv hluav taws xob.
2. Cov cuab yeej SMD uas tsis siv cov thawv ntim khoom los tiv thaiv yuav tsum tsis txhob nkag rau qhov chaw.
3. Thaum noj cov yam khoom los ntawm ESD tiv thaiv lub thawv, nws yuav tsum tau nqa tawm ntawm txoj hlua hluav taws xob hauv tshuab hluav taws xob. Ua ib tug neeg ua haujlwm, peb lub ntsiab lus hauv qab no yuav tsum muaj kev pom zoo:
(1) Yuav tsum tau hnav zoo li qub tag nrho.
(2) Hnav ib lub tsho tiv thaiv uas zoo li qub uas muaj kev sib cuag zoo ntawm daim tawv nqaij thiab muaj lub hauv paus zoo.
(3) Thaum hu cuag SMD cov khoom muaj nqis, nws yog qhov zoo tshaj rau hnav cov rings tsis zoo los yog cov tswv yim ntiv tes.
4. Rau cov khoom uas tsis muaj cov thawv ntim khoom tiv thaiv, lawv yuav tsum nkag rau qhov chaw ua haujlwm tom qab tua hluav taws xob.
5. Cov neeg saib xyuas yuav tsum tau muab cov neeg tseem ceeb ntawm cov neeg lag luam txhawm rau txhawm rau pom tias lub pob tes taw nyob hauv txhua lub sijhawm.
6, cov khaub ncaws tsis zoo, kev kos duab thiab lwm yam ntaub ntawv yuav tsis chwv cov khoom.
7. Thaum tuav cov khoom siv ceev, tsis txhob kov cov kab thiab cov lugs.
8. Thaum twg yuav tsum ntxuav cov khoom ua ntej, yuav tsum tsis txhob txhuam cov yas txhuam hniav. Lawv yuav tsum raug ntxuav nrog cov tshuaj txhuam hniav.
9. Tag nrho cov cuab yeej, khoom lag luam, khoom siv thiab cov khoom siv uas yuav tsum tau siv rau ntawm qhov chaw ua haujlwm thiab tsis muaj kev ua haujlwm ntawm lub cev yuav tsum tau muab tso rau hauv lub rooj tiv thaiv lub rooj (lub rooj).
10. Nws yog txwv tsis pub rov qab siv lub tshuab thawv ntim cov thawv ntim khoom.
11, nyob rau hauv kev siv vuam siv, siv hluav taws xob tiv thaiv uas tsis tshua siv phom me.
12. Siv tsawg-voltage DC hluav taws xob ntsaws nrig nrog av nkhaus thiab lwm cov khoom siv mounting.
13. Cov neeg txawv tebchaws nkag mus rau hauv qhov chaw thiab tsis tau noj cov tshuaj tiv thaiv thiab tsis chwv cov khoom.
14. Txhua yam khoom siv rau ntawm qhov chaw tsim nyog yuav tsum siv cov kev ntsuas los tiv thaiv.
