Momwe mungayesere magwiridwe antchito a PCB mwachangu?

Zikafika pakujambula mwachangu kwa PCB, imodzi mwamagawo ovuta kwambiri ndikuyesa magwiridwe antchito amtunduwu.Ndikofunikira kuwonetsetsa kuti prototype imagwira bwino ntchito ndikukwaniritsa zofunikira zonse zomwe kasitomala amanenera.Capel ndi kampani yotsogola yomwe imagwira ntchito mwachangu popanga ma PCB opanga ma prototyping ndikupanga ma voliyumu a board, ndipo timamvetsetsa kufunikira kwa gawo loyesali popereka ma board apamwamba komanso apamwamba kwambiri kwa makasitomala athu.

Pokhala ndi zaka zoposa 15 za luso laukadaulo komanso luso lamakampani, Capel yakhazikitsa njira yoyendetsera kayendetsedwe kabwino kwambiri yomwe imakhudza mbali zonse za kupanga kuyambira pakugula mpaka kupanga mpaka kuyesa. Dongosolo lonseli limatsimikizira kuti gulu lililonse ladera lomwe timapanga likukwaniritsa miyezo yapamwamba kwambiri komanso limakwaniritsa zofunikira zamakasitomala.

Tsopano, tiyeni tiwone njira zina zoyesera magwiridwe antchito a PCB mwachangu:

1. Kuyang'ana m'maso:
Gawo loyamba poyesa magwiridwe antchito a PCB mwachangu ndikuwunika kowonekera. Yang'anani zolakwika zilizonse zowoneka, monga zowotcherera, zida zosalongosoka, kapena zizindikiro zomwe zitha kuwonongeka kapena kusowa. Kuyang'anitsitsa kowoneka bwino kungathandize kuzindikira zovuta zilizonse musanasamukire ku njira zapamwamba zoyesera.

2. Mayeso opitiliza pamanja:
Kuyesa kopitilira kumaphatikizapo kuyang'ana kulumikizana pakati pa mfundo zosiyanasiyana pa bolodi yozungulira. Pogwiritsa ntchito ma multimeter, mutha kuyesa ma trace, vias, ndi zigawo kuti zipitirire. Njirayi imawonetsetsa kuti malumikizano onse amagetsi apangidwa moyenera ndikugwira ntchito moyenera.

3. Kuyesa kogwira ntchito:
Kuyesa kogwira ntchito ndi gawo lofunikira pakuzindikira momwe ma prototypes a PCB amathandizira. Zimaphatikizapo kuyika ma prototypes muzochitika zosiyanasiyana ndikuwunika mayankho awo. Kutengera ndi zovuta za bolodi, kuyesa kwa magwiridwe antchito kungaphatikizepo kuyang'ana zolowa ndi zotuluka, kutsimikizira magwiridwe antchito amtundu uliwonse, ndikuyesa njira zosiyanasiyana zogwirira ntchito.

4. Mphamvu pamayeso:
Kuyesa kwamphamvu kumaphatikizapo kugwiritsa ntchito mphamvu pa prototype ndikuwona machitidwe ake. Mayesowa amawonetsetsa kuti bolodi silikuwonetsa zovuta zilizonse zokhudzana ndi mphamvu, monga mabwalo amfupi, kutentha kwambiri, kapena machitidwe osayembekezereka. Kuwunika kuchuluka kwa ma voltage, kulolerana, ndi kugwiritsa ntchito mphamvu panthawi yoyeserera ndikofunikira kuti muzindikire zolakwika zilizonse.

5. Kuyesa kukhulupirika kwa ma Signal:
Cholinga cha kuyesa kukhulupirika kwa chizindikiro ndikutsimikizira mtundu ndi kudalirika kwa ma siginecha amphamvu pa board board. Pogwiritsa ntchito oscilloscope kapena logic analyzer, mukhoza kuyeza khalidwe la chizindikiro ndi kufalitsa kwake ndikuyang'ana phokoso kapena kupotoza kulikonse. Mayesowa amawonetsetsa kuti bolodi imatha kutumiza ndikulandila zikwangwani molondola popanda kutaya kapena kuwononga deta.

6. Kuyesa kwachilengedwe:
Kuyesa kwachilengedwe kumachitidwa kuti awone momwe mtundu wa PCB wofulumira umalimbana ndi mikhalidwe yosiyanasiyana yakunja. Zimaphatikizapo kuyika chithunzichi ku kusintha kwa kutentha, kuchuluka kwa chinyezi, kugwedezeka ndi zinthu zina zachilengedwe kuti zitsimikizire kulimba kwake komanso kulimba. Mayesowa ndi ofunikira makamaka pama prototypes omwe amagwiritsidwa ntchito pazovuta kapena zochitika zinazake.

7. Mayeso a Benchmark:
Kuyerekeza kwa magwiridwe antchito kumaphatikizapo kufananitsa kachitidwe ka prototype ku mulingo wodziwikiratu kapena zinthu zofananira pamsika. Poyesa mayeso a benchmark, mutha kuwunika momwe mungagwiritsire ntchito mphamvu, kuthamanga, kugwiritsa ntchito mphamvu ndi magawo ena ofunikira amtundu wanu wa PCB mwachangu. Zimathandizira kuwonetsetsa kuti ma prototypes akukwaniritsa kapena kupitilira magawo omwe amafunikira.

Potsatira njira zoyeserazi, mutha kuwunika bwino ntchito ya mtundu wanu wachangu wa PCB. Kudzipereka kwa Capel pakuwongolera bwino kumatsimikizira kuti timayesa mayeso onsewa ndi zina zambiri, ndikutsimikizira kuti gulu lililonse ladera lomwe timapereka limakwaniritsa zomwe makasitomala amafuna kuti akhale apamwamba komanso magwiridwe antchito abwino. Gulu lathu la akatswiri odziwa zambiri limagwira ntchito molimbika kuti lipitilize kukonza njira zathu zoyesera kuti tipatse makasitomala ma prototypes odalirika komanso abwino.

Powombetsa mkota

Kuyesa magwiridwe antchito amtundu wa PCB mwachangu ndikofunikira kuti muwonetsetse kuti imagwira ntchito bwino komanso ikukwaniritsa zomwe kasitomala amafuna. Ali ndi zaka 15 komanso machitidwe okhwima owongolera khalidwe, Capel amagwira ntchito popanga ma PCB mwachangu komanso kupanga ma board ozungulira. Mutha kuwonetsetsa kudalirika komanso mtundu wama prototypes anu othamanga a PCB potsatira njira zingapo zoyesera kuphatikiza kuyang'anira zowonera, kuyesa mosalekeza pamanja, kuyesa magwiridwe antchito, kuyesa mphamvu, kuyesa kukhulupirika kwa ma sign, kuyesa chilengedwe, ndi kuyika chizindikiro. Khulupirirani Capel pazosowa zanu zonse za PCB ndikuwona zinthu ndi ntchito zathu zapadera.
