Kunzwa kwemidziyo yemagetsi kuri kuramba kuchikwira, izvo zvinoda kuti michina ive nesimba rekurwisa-kupindira. Naizvozvo, PCB kugadzira kwave kuoma. Maitiro ekuvandudza kugona kwe-anti-kupindira kwePCB yave imwe yezvinhu zvakakosha izvo mainjiniya mazhinji anoteerera. Ichi chinyorwa chichasuma mamwe matipi ekudzikisa ruzha uye kukanganiswa kwemagetsi muPCB dhizaini.

Aya anotevera matipi makumi maviri nemana ekudzikisa ruzha uye kukanganiswa kwemagetsi muPCB dhizaini, yakapfupikiswa mushure memakore ekugadzira:

(1) Low-speed machipisi anogona kushandiswa panzvimbo yemachipisi anomhanya. High-speed chips inoshandiswa munzvimbo dzakakosha.

(2) Inopikisa inogona kubatanidzwa munhevedzano kuti ideredze kusvetuka kweyepamusoro uye yakaderera mipendero yedunhu rekutonga.

(3) Edza kupa imwe nzira yekunyorovesa kune relay, nezvimwe.

(4) Shandisa yakaderera frequency frequency iyo inosangana nezvinodiwa system.

(5) Jenareta yewachi iri padyo sezvinobvira kune mudziyo uchishandisa wachi. Iyo goko reiyo quartz crystal oscillator inofanira kuiswa pasi.

(6) Sungai nzvimbo yewachi newaya yepasi uye chengetedza waya yewachi ipfupi sezvinobvira.

(8) Mhedziso isingabatsiri yeMCD inofanirwa kubatanidzwa kune yakakwirira, kana kudzika, kana kutsanangurwa sekuguma kwekubuda, uye kupera kwedunhu rakasanganiswa rinofanira kubatanidzwa kune ivhu rekupa magetsi rinofanira kubatanidzwa, uye harifanirwe kusiiwa richiyangarara. .

(9) Usasiye nzvimbo yekuisa yegedhi redunhu risiri kushandiswa. Iyo yakanaka yekuisa terminal yeiyo isina kushandiswa inoshanda amplifier yakadzikwa, uye iyo yakaipa yekuisa terminal yakabatana kune inobuda terminal.

(10) Pamapuranga akadhindwa, edza kushandisa mitsara makumi mana neshanu panzvimbo ye45-fold mitsara kuderedza kubuda kwekunze uye kubatanidza zviratidzo zvepamusoro-frequency.

(12) Shandisa-single-point simba uye imwe-point grounding kune imwechete uye mbiri mapaneru. Mutsara wemagetsi uye mutsara wepasi unofanira kunge wakakora sezvinobvira. Kana hupfumi huchikwanisa, shandisa multilayer board kuderedza capacitive inductance yemagetsi uye pasi.

(13) Wachi, bhazi, uye chip sarudza masaini anofanira kunge ari kure neI / O mitsetse uye zvibatanidza.

(14) Iyo analog voltage yekuisa mutsara uye referensi voltage terminal inofanirwa kunge iri kure sezvinobvira kubva kudhijitari redhijitari siginecha mutsara, kunyanya wachi.

(15) Yemidziyo yeA/D, chikamu chedhijitari uye chikamu cheanalogi chingave chakabatana pane kuyambuka.

(16) Mutsara wewachi perpendicular kumutsara weI / O une kukanganisa kuduku kudarika mutsara weI / O, uye mapini echikamu chewachi ari kure neI / O cable.

(17) Mapini echikamu anofanira kunge ari mapfupi sezvinobvira, uye decoupling capacitor pini inofanira kuva pfupi sezvinobvira.

(18) Mutsetse wekiyi unofanira kuva wakakora sezvinobvira, uye pasi rinodzivirira rinofanira kuwedzerwa kumativi ose. Mutsara wepamusoro-soro unofanira kunge uri pfupi uye wakarurama.

(19) Mitsetse inonzwa ruzha haifanire kuenderana nepamusoro-ikozvino, mitsetse yekuchinja-inomhanya.

(20) Usafambisa waya pasi pekristaro yequartz uye pasi pemidziyo inonzwa ruzha.

(21) Pamaseketi echiratidzo asina simba, usaite zvishwe zvazvino zvakatenderedza pasi-frequency maseketi.

(22) Usagadzira loop pachiratidzo. Kana zvisingadzivisiki, ita kuti loop nzvimbo ive diki sezvinobvira.

(23) Imwe decoupling capacitor per integrated circuit. Iyo diki yakakwira-frequency bypass capacitor inofanirwa kuwedzerwa kune yega yega electrolytic capacitor.

(24) Shandisa guru-capacity tantalum capacitors kana juku capacitors panzvimbo ye electrolytic capacitors kubhadharisa uye kuburitsa simba rekuchengetedza capacitors. Paunenge uchishandisa tubular capacitors, nyaya yacho inofanira kuiswa pasi.
