Za PCB Board Design Yathu

Tikapanga bolodi la PCB, timakhalanso ndi malamulo: choyamba, konzekerani malo akuluakulu malinga ndi ndondomeko ya chizindikiro, ndiyeno tsatirani "chigawo choyamba chovuta kenako chosavuta, chigawo chachikulu mpaka chaching'ono, chizindikiro champhamvu ndi kulekanitsa chizindikiro chofooka, chapamwamba ndi chochepa.Zizindikiro zosiyana, zizindikiro zosiyana za analogi ndi digito, yesetsani kupanga mawaya afupiafupi momwe mungathere, ndikupanga masanjidwewo kukhala oyenera momwe mungathere";chidwi chapadera chiyenera kuperekedwa kusiyanitsa "signal ground" ndi "power ground";Izi makamaka pofuna kupewa mphamvu ya pansi Mzere nthawi zina umakhala ndi mphamvu yaikulu yodutsamo.Ngati izi zidziwitsidwa mu terminal ya siginecha, zimawonetsedwa ku terminal yotulutsa kudzera mu chip, motero zimakhudza magwiridwe antchito amagetsi osinthira magetsi.
Kenaka, malo okonzekera ndi mawaya a zigawozo ziyenera kukhala zogwirizana momwe zingathere ndi mawaya a chigawo cha dera, chomwe chidzakhala chosavuta kwambiri kuti chisamalidwe ndi kuyang'anitsitsa.
Waya wapansi uyenera kukhala waufupi komanso wotakata, ndipo waya wosindikizidwa womwe ukudutsa pamagetsi osinthasintha uyeneranso kukulitsidwa momwe kungathekere.Nthawi zambiri, timakhala ndi mfundo yolumikizira, waya wapansi ndi waukulu kwambiri, waya wamagetsi ndi wachiwiri, ndipo waya wamagetsi ndi wocheperako.
Chepetsani kuzungulira kwa mayankho, malo olowera ndi kuwongolera zotulutsa zotulutsa momwe mungathere, cholinga ichi ndikuchepetsa kusokoneza kwa phokoso lamagetsi osinthira.

One-Stop Solution

Zida zopangira ma inductive monga ma thermistors ziyenera kusungidwa kutali momwe zingathere ndi magwero otentha kapena zida zozungulira zomwe zimayambitsa kusokoneza.
Mtunda wapakati pakati pa tchipisi tapawiri pamizere uyenera kukhala wamkulu kuposa 2mm, ndipo mtunda wapakati pa chip resistor ndi chip capacitor uyenera kukhala wamkulu kuposa 0.7mm.
Cholowetsa fyuluta cholowera chiyenera kuyikidwa pafupi ndi mzere womwe uyenera kusefedwa.
Pamapangidwe a board a PCB, mavuto omwe amapezeka kwambiri ndi malamulo achitetezo, EMC ndi kusokoneza.Kuti tithane ndi mavutowa, tiyenera kulabadira zinthu zitatu popanga: mtunda wamtunda, mtunda wa creepage ndi mtunda wolowera.Zotsatira.
Mwachitsanzo: Creepage mtunda: pamene athandizira voteji ndi 50V-250V, ndi LN kutsogolo fuse ndi ≥2.5mm, pamene athandizira voteji ndi 250V-500V, ndi LN kutsogolo fuseji ndi ≥5.0mm;chilolezo magetsi: pamene athandizira voteji ndi 50V-250V, L-N ≥ 1.7mm kutsogolo fuseji, pamene athandizira voteji ndi 250V-500V, L-N ≥ 3.0mm kutsogolo fuseji;palibe chofunikira pambuyo pa fuseji, koma yesetsani kusunga mtunda wina kuti mupewe kuwonongeka kwafupipafupi kwa magetsi;choyambirira mbali AC kuti DC gawo ≥ 2.0 mm;mbali yoyamba DC pansi mpaka pansi ≥4.0mm, monga mbali yoyamba mpaka pansi;mbali yoyamba ku mbali yachiwiri ≥6.4mm, monga optocoupler, Y capacitor ndi zigawo zina za chigawocho, malo a pini ndi ocheperapo kapena ofanana ndi 6.4mm kuti atseke;thiransifoma magawo awiri ≥6.4mm kapena kuposerapo, ≥8mm kwa kutchinjiriza kumalimbitsa.

FAQ

Q1: Mumawonetsetsa bwanji kuti ma PCB ali abwino?
A1: Ma PCB athu onse ndi mayeso a 100% kuphatikiza Mayeso a Flying Probe, E-test kapena AOI.

Q2: Kodi nthawi yotsogolera ndi chiyani?
A2: Zitsanzo zimafunikira masiku 2-4 ogwirira ntchito, kupanga misa kumafunikira masiku 7-10 ogwira ntchito.Zimatengera mafayilo ndi kuchuluka kwake.

Q3: Kodi ndingapeze mtengo wabwino kwambiri?
A3: Inde.Kuthandiza makasitomala kuwongolera mtengo ndizomwe timayesetsa kuchita nthawi zonse.Akatswiri athu adzapereka mapangidwe abwino kwambiri kuti apulumutse zinthu za PCB.
