Static magetsi kubva kumuviri wemunhu, nharaunda uye kunyange mukati zvigadzirwa zvemagetsi zvinogona kukonzera kukuvara kwakasiyana siyana kune chaiyo semiconductor machipisi, senge kupinda mukati mutete kuputira dura mukati mezvinhu; Kukuvadza kumasuwo eMOSFET uye CMOS zvinhu; Trigger kukiya mune CMOS mudziyo; Ipfupi-redunhu regedza kusasarura PN mhesano; Ipfupi-redunhu yakanaka kusarura PN mhesano; Sungunusa waya yesimbi kana waya yealuminium mukati mechinhu chinoshanda. Kuti ubvise kupindirana uye kukuvara kwemagetsi emagetsi (ESD) kumidziyo yemagetsi, zvinodikanwa kutora matanho akasiyanasiyana ekudzivirira.

munguva Pcb bhodhi dhizaini, ESD kuramba kwePCB kunogona kuwanikwa kuburikidza nekugadzika, kurongeka kwakakodzera uye kumisikidza. Munguva yekugadzira dhizaini, shanduko zhinji dhizaini dzinogona kungogumira pakuwedzera kana kubvisa zvinhu kuburikidza nekufanotaura. Nekugadzirisa pcb marongero uye wiring, ESD inogona kudzivirirwa zvakanaka. Heano mamwe maitiro anowanzo dzivirirwa.

Maitiro ekuziva ESD kuramba dhizaini yePCB

1. Shandisa multi-rukoko pcb kure sezvinobvira. Inofananidzwa nePBB-yakatenderedzwa pcb, iyo ndege yepasi uye ndege yemagetsi, pamwe nekusiyana kwepakati pakati petambo yechiratidzo netambo yepasi kunogona kudzikisira iyo yakajairika-modhi impedance uye inductive coupling, uye kuita kuti isvike 1/10 kusvika 1/100 ye kaviri mativi pcb. Edza kumisikidza rukoko rwechiratidzo chega chega padhuze nesimba kana pasi pevhu. Kune yakakwira-kuwanda PCBS ine zvikamu pane ese ari maviri epamusoro uye ezasi maficha, akapfupika kubatana, uye mizhinji yekuzadza pasi, funga kushandisa mitsara yemukati.

2. Kune pcb-mativi pcb, yakasimba rakarukwa magetsi uye yevhu grid inofanira kushandiswa. Tambo yemagetsi iri padhuze nepasi uye inofanirwa kuve yakabatana zvakanyanya sezvinobvira pakati pemitsara yakatwasuka uye yakatwasuka kana nzvimbo dzekuzadza. Iyo grid saizi yeimwe divi ichave yakaderera kana yakaenzana ne60mm, kana pasi pe13mm kana zvichibvira.

3. Onai kuti dunhu rega rega rakaumbana sezvinobvira.

4. Isa zvese zvinobatanidza padivi nepazvinogona napo.

5. Kana zvichikwanisika, tungamira tambo yemagetsi kubva pakati pekadhi kure nenzvimbo dzinogona kutungamira kukuvara kweESD.

6, pamatanho ese ePBB pazasi pechisungo chinoburitsa kunze kwenyaya (zviri nyore kurohwa zvakananga neESD), isa chassis yakafara kana polygon izere pasi, wozvibatanidza pamwe chete nemakomba panhambo dzinenge 13mm.

7. Isa maburi anokwira pamucheto wekadhi, uye mapads ekumusoro neepazasi emvura yakavhurika akabatana pasi pechassis yakatenderedza maburi anokwira.

8, gungano rePCBB, usashandise chero chinogadziriswa kumusoro kana pasi pepasi. Shandisa zvimisikidzo zvine zvakavakirwa-mukati ma washer kupa yakasimba kubatana pakati pePBB nesimbi chassis / nhoo kana rutsigiro pasi pevhu.

9, mune yega yega yega pakati pechassis nedunhu redunhu, kumisikidza imwechete “nzvimbo yekuzviparadzanisa”; Kana zvichibvira, chengetedza nzvimbo yacho pa0.64.

10, kumusoro uye pasi pekadhi padyo nenzvimbo yekuisa gomba, yega yega 100mm padivi pechassis pasi uye pasi redunhu ine 1.27mm yakafara mutsara pamwe chete. Padhuze neaya ekubatanidza mapoinzi, pad kana inokwira gomba rekumisikidza inoiswa pakati pekassis pasi nenzvimbo yedunhu. Iyi yekubatana kwepasi inogona kutemwa nejasi kuti igare yakavhurika, kana kusvetuka nemagineti mabheji / akakwira frequency capacitors.

11, kana bhodhi redunhu rikasaiswa mubhokisi resimbi kana chidziviriro, pamusoro uye pasi peseketi bhodhi chassis pasi waya haigone kuvezwa neiyo solder kuramba, kuitira kuti vakwanise kushandiswa seESD arc kuisa electrode.

12. Isa mhete kutenderedza dunhu nenzira inotevera.

(1) Kuwedzera kune yekumucheto chinongedzo uye chassis, iyo yakazara periphery yeringi yekuwana.

(2) Ita shuwa kuti hupamhi hwematanho ese hwakakura kupfuura 2.5mm.

(3) Makomba acho akabatana mumhete mu13mm dzese.

(4) Batanidza iyo annular ivhu uye zvakajairika ivhu remazhinji-masenduru wedunhu pamwechete.

(5) Pamapaneru akapetwa akaiswa mumatare esimbi kana michina yekudzivirira, iyo mhete pasi ichave yakabatana kune yakajairika nzvimbo yedunhu. Iyo isina kuvharwa mativi-maviri mativi wedunhu anofanirwa kuve akabatanidzwa kune iyo mhete pasi, iyo mhete pasi haifanire kuvezwa nekuyerera, kuitira kuti mhete pasi inogona kuita se ESD kuburitsa tsvimbo, ingangoita 0.5mm yakafara gwanza pane iyo mhete pasi (ese akaturikidzana), kuitira kuti chiuno chihombe chinogona kudzivirirwa. Wiring yechiratidzo haifanire kunge iri pasi pe0.5mm kure negiringi pasi.

Munzvimbo iyo inogona kurohwa zvakananga neESD, tambo yepasi inofanira kuiswa padhuze nechero mutsara wetsiva.

14. Dunhu reI / O rinofanirwa kunge riri padhuze nechinobatanidza chinoenderana sezvinobvira.

15. Dunhu rinobatwa neESD rinofanira kuiswa padyo nepakati peseketi, kuitira kuti mamwe macircuit agone kuvapa zvavanoita.

16, inowanzoiswa mune akateedzana resistor uye magineti marozari kumagumo ekugashira, uye kune avo tambo madhiraivhi ari panjodzi neESD, anogona zvakare kufunga nezvekuisa dzakateedzana resistor kana magineti marozari kumagumo emutyairi.

17. Anodzivirira kwenguva pfupi anowanzoiswa panogamuchirwa. Shandisa waya ipfupi gobvu (isingasviki 5x upamhi, zvirinani isingasviki 3x upamhi) kubatanidza kune chassis pasi. Iyo mireza uye pasi mitsara kubva kune chinongedzo chinofanira kuve chakabatana zvakananga kune chinononoka dziviriro pamberi pese dunhu risinga sunganidzwe.

18. Isa iyo firita capacitor pane chinobatanidza kana mukati me25mm yedunhu rinogashira.

(1) Shandisa tambo ipfupi uye gobvu kubatanidza chassis kana iyo inotambira dunhu (kureba isingasvike ka5 yakafara, zvirinani isingasviki katatu zvakapetwa).

(2) Tambo yemasaini netambo yepasi inotanga kubatanidzwa kune iyo capacitor uyezve inosangana nedunhu rinogashira.

19. Ita shuwa kuti tambo yechiratidzo ipfupi sezvinobvira.

20. Kana kureba kwetambo dzemasaini kwakakura kudarika 300mm, tambo yepasi inofanira kuiswa zvakafanana.

21. Ita shuwa kuti nzvimbo yekurembera iri pakati pechiratidzo netambo inoenderana idiki sezvinobvira. Pamitsara yakareba yemasaini, chinzvimbo chetambo yechiratidzo nemutsara wepasi chinofanira kuchinjwa masendimita mashoma mashoma kudzikisa nzvimbo yakatenderera.

22.Dhiraivha zviratidzo kubva pakati penetiweki kune akawanda anogamuchira maseketi.

23. Iva nechokwadi chekuti nzvimbo yakatenderera pakati pekupihwa simba nepasi ishoma sezvinobvira. Isa yakakwira frequency capacitor padhuze nechero simba pini yeiyo IC chip.

24. Isa yakakwira frequency yekupfuura capacitor mukati me80mm yeimwe yekubatanidza.

25. Pazvinokwanisika, zadza nzvimbo dzisina kushandiswa nepasi, uchibatanidza matese ekuzadza panguva dze60mm.

26. Ita shuwa kuti ivhu rakabatana kumicheto miviri yakatarisana yechero nzvimbo hombe yekuzadza ivhu (inenge yakakura kupfuura 25mm * 6mm).

27. Kana kureba kwekuvhura pane magetsi kana ndege yepasi ichidarika 8mm, batanidza mativi maviri ekuvhura netambo nhete.

28. Reset mutsetse, kuvhiringidza chiratidzo mutsetse kana mucheto rukungiso chiratidzo mutsetse havafaniri kuiswa pedyo kumucheto pcb.

29. Unganidza maburi anokwira nedunhu rinoenderana, kana kuzvitsaura.

(1) Kana bracket resimbi richifanirwa kushandiswa nesimbi inodzivirira kana chassis, zero ohm kuramba kunofanirwa kushandiswa kuona kubatana.

(2) sarudza hukuru hwegomba rekumisikidza kuzadzikisa kuisirwa kwakavimbika kwesimbi kana rutsigiro rweplastiki, kumusoro uye pasi pegomba rekumisikidza kushandisa padhi hombe, iyo yepasi padhi haigone kushandisa kuyerera kwemvura, uye kuona kuti pasi Padhi haishandisi wave yekutenderera nzira yekumonera.

30. Tambo dzemasaini dzakadzivirirwa uye tambo dzemasaini dzisina kudzivirirwa hadzigone kurongwa zvakafanana.

Kunyanya kutariswa kunofanirwa kubhadharwa kune iyo wiring yekusetazve, kukanganisa uye kudzora mitsara yemasaini.

(1) Yakakwira-frequency kusefa kunofanirwa kushandiswa.

(2) Gara kure nekuisa uye kuburitsa maseketi.

(3) Gara kure nemucheto webhodhi redunhu.

32, PCB inofanira kuiswa muchassis, usaise munzvimbo yekuvhura kana majoini emukati.

Teerera kune wiring yeiyo tambo yechiratidzo pasi peiyo magnetic bead, pakati pemapads uye inogona kubata iyo magnetic bead. Humwe huravha hunofambisa magetsi zvakanaka uye hunogona kuburitsa isingatarisirwi nzira dzinofamba.

Kana kesi kana mamaboard ekuisa akati wandei emabhodhi edunhu, anofanirwa kuve anonyanya kunetseka kune static magetsi wedunhu bhodhi pakati.
