Kumverera kwa zida zamagetsi kukukulirakulira, zomwe zimafuna kuti zidazo zikhale ndi mphamvu zotsutsana ndi kusokoneza. Chifukwa chake, PCB kupanga kwakhala kovuta kwambiri. Momwe mungasinthire luso lodana ndi kusokoneza kwa PCB yakhala imodzi mwazinthu zazikulu zomwe akatswiri ambiri amalabadira. Nkhaniyi ipereka maupangiri ena ochepetsera phokoso ndi kusokoneza kwamagetsi pamapangidwe a PCB.

Zotsatirazi ndi maupangiri 24 ochepetsera phokoso ndi kusokoneza kwamagetsi pakupanga kwa PCB, mwachidule patatha zaka zopanga:

(1) Tchipisi zothamanga pang’ono zitha kugwiritsidwa ntchito m’malo mwa tchipisi zothamanga kwambiri. Tchipisi zothamanga kwambiri zimagwiritsidwa ntchito m’malo ofunikira.

(2) Wotsutsa amatha kulumikizidwa mndandanda kuti achepetse kuthamanga kwapamwamba ndi m’mphepete mwa gawo lowongolera.

(3) Yesani kupereka mtundu wina wa damping kwa ma relay, ndi zina.

(4) Gwiritsani ntchito wotchi yapafupipafupi kwambiri yomwe imakwaniritsa zofunikira zadongosolo.

(5) Jenereta ya wotchi ili pafupi kwambiri ndi chipangizo chogwiritsira ntchito wotchi. Chigoba cha quartz crystal oscillator chiyenera kukhazikitsidwa.

(6) Tsekani malo a wotchi ndi waya pansi ndipo waya wotchiyo ikhale yayifupi momwe mungathere.

(8) Mapeto opanda pake a MCD ayenera kulumikizidwa kumtunda, kapena kukhazikika, kapena kufotokozedwa ngati mapeto otuluka, ndipo mapeto a dera lophatikizika lomwe liyenera kugwirizanitsidwa ndi malo opangira magetsi ayenera kulumikizidwa, ndipo sayenera kusiyidwa kuyandama. .

(9) Osasiya cholowera cholowera pachipata chomwe sichikugwiritsidwa ntchito. Malo olowetsamo abwino a amplifier osagwiritsidwa ntchito osagwiritsidwa ntchito amakhazikika, ndipo cholumikizira cholakwika chimalumikizidwa ndi chotulutsa.

(10) Kwa matabwa osindikizidwa, yesetsani kugwiritsa ntchito mizere ya 45 m’malo mwa mizere 90 kuti muchepetse kutulutsa kwakunja ndi kugwirizana kwa zizindikiro zapamwamba.

(11) The printed board is partitioned according to the frequency and current switching characteristics, and the noise components and non-noise components should be farther apart.

(12) Gwiritsani ntchito mphamvu ya mfundo imodzi ndi maziko a mfundo imodzi pamagulu amodzi ndi awiri. Mzere wamagetsi ndi mzere wapansi uyenera kukhala wandiweyani momwe ungathere. Ngati chuma ndi chotsika mtengo, gwiritsani ntchito bolodi la multilayer kuti muchepetse capacitive inductance ya magetsi ndi nthaka.

(13) Wotchi, basi, ndi ma chip sankhani ma sign ayenera kukhala kutali ndi mizere ya I/O ndi zolumikizira.

(14) Mzere wolowetsa voteji ya analogi ndi chotengera cha voliyumu yolumikizira ziyenera kukhala kutali kwambiri ndi mzere wa siginecha ya digito, makamaka wotchi.

(15) Pazida za A/D, gawo la digito ndi gawo la analogi limatha kukhala lolumikizana kuposa kuwoloka.

(16) Mzere wa wotchi wa perpendicular kwa mzere wa I / O uli ndi zosokoneza pang’ono kusiyana ndi mzere wa I / O wofanana, ndipo zikhomo za chigawo cha wotchi zili kutali ndi chingwe cha I / O.

(17) Zikhomo za chigawocho ziyenera kukhala zazifupi momwe zingathere, ndipo zikhomo zowonongeka ziyenera kukhala zazifupi momwe zingathere.

(18) Mzere wachinsinsi uyenera kukhala wokhuthala monga momwe kungathekere, ndipo malo otetezera ayenera kuwonjezeredwa mbali zonse. Mzere wothamanga kwambiri uyenera kukhala waufupi komanso wowongoka.

(19) Mizere yomwe imakhudzidwa ndi phokoso sayenera kufanana ndi mizere yothamanga kwambiri, yothamanga kwambiri.

(20) Osayendetsa mawaya pansi pa kristalo wa quartz komanso pansi pazida zomwe sizimva phokoso.

(21) Pamazungulira ofooka, musapange malupu apano mozungulira ma frequency otsika.

(22) Osapanga lupu pachizindikiro. Ngati sichingalephereke, pangani malo ozungulira kukhala ochepa momwe mungathere.

(23) One decoupling capacitor per integrated circuit. A small high-frequency bypass capacitor must be added to each electrolytic capacitor.

(24) Gwiritsani ntchito mphamvu zazikulu za tantalum capacitor kapena juku capacitor m’malo mwa electrolytic capacitors kuti mupereke ndi kutulutsa ma capacitor osungira mphamvu. Mukamagwiritsa ntchito ma capacitors a tubular, mlanduwo uyenera kukhazikika.
