Kuchokera ku PCB World.

Kaya ndi bolodi yopangidwa ndi munthu wina kapena bolodi ya PCB yopangidwa ndi inu nokha, chinthu choyamba kuti mupeze ndikuwunika kukhulupirika kwa bolodi, monga tining, ming'alu, mabwalo afupikitsa, mabwalo otseguka, ndi kubowola.Ngati bolodi ndi lothandiza kwambiri Khalani okhwima, ndiye kuti mukhoza kuyang'ana mtengo wotsutsa pakati pa magetsi ndi waya pansi panjira.

M'mikhalidwe yabwino, bolodi wodzipangira yekha kukhazikitsa zigawo zikuluzikulu pambuyo tinning anamaliza, ndipo ngati anthu atero, ndi chabe chopanda zitini PCB bolodi ndi mabowo.Muyenera kukhazikitsa zigawozo nokha mukapeza..

Anthu ena amadziwa zambiri za matabwa a PCB omwe amapanga, choncho amakonda kuyesa zigawo zonse mwakamodzi.Ndipotu, ndi bwino kuchita pang'onopang'ono.

PCB dera board pansi debugging
Zatsopano PCB bolodi debugging angayambe kuchokera magetsi gawo.Njira yotetezeka ndikuyika fusesi ndikugwirizanitsa magetsi (pokhapokha, ndi bwino kugwiritsa ntchito magetsi okhazikika).

Gwiritsani ntchito magetsi okhazikika kuti mukhazikitse chitetezo cha overcurrent, ndikuwonjezera pang'onopang'ono mphamvu yamagetsi okhazikika.Izi zimafunika kuyang'anira momwe akulowetsa, magetsi olowera ndi magetsi otuluka pa bolodi.

Pamene voteji kusinthidwa m'mwamba, palibe over-panopa chitetezo ndi linanena bungwe voteji ndi yachibadwa, ndiye zikutanthauza kuti magetsi mbali ya bolodi alibe vuto.Ngati mphamvu yamagetsi yamagetsi kapena chitetezo chaposachedwa chikupitilira, ndiye kuti chifukwa cha cholakwikacho chiyenera kufufuzidwa.

Kuyika chigawo cha board board
Pang'onopang'ono ikani ma modules panthawi yokonza zolakwika.Pamene gawo lililonse kapena ma module angapo aikidwa, tsatirani njira zomwe zili pamwambazi kuti muyese, zomwe zimathandiza kupewa zolakwika zina zobisika kumayambiriro kwa mapangidwe, kapena zolakwika za unsembe wa zigawo zikuluzikulu, zomwe zingayambitse kuwotcha mopitirira muyeso.Zigawo zoipa.

Ngati kulephera kuchitika pakukhazikitsa, njira zotsatirazi zimagwiritsidwa ntchito kuthetsa mavuto:

Njira yothetsera mavuto yoyamba: njira yoyezera voteji.

Pamene chitetezo chamakono chikuchitika, musathamangire kusokoneza zigawozo, choyamba tsimikizirani mphamvu ya pini yamagetsi ya chip chilichonse kuti muwone ngati ili pamtunda.Ndiye onani voteji Buku, voteji ntchito, etc. nayenso.

Mwachitsanzo, silicon transistor ikayatsidwa, voteji yapamphako ya BE idzakhala pafupifupi 0.7V, ndipo makulidwe a CE nthawi zambiri amakhala 0.3V kapena kuchepera.

Poyesa, amapezeka kuti magetsi a BE junction ndi apamwamba kuposa 0.7V (ma transistors apadera monga Darlington sakuphatikizidwa), ndiye kuti n'zotheka kuti BE junction ndi yotseguka.Sequentially, yang'anani voteji pamalo aliwonse kuti muthetse vutolo.

Njira yothetsera mavuto yachiwiri: njira yojambulira chizindikiro

Njira yojambulira chizindikiro ndiyovuta kwambiri kuposa kuyeza voteji.Gwero la siginecha likatumizidwa kumalo olowera, tiyenera kuyeza mawonekedwe a mafunde a mfundo iliyonse kuti tipeze cholakwika mu mawonekedwe a waveform.

Zachidziwikire, mutha kugwiritsanso ntchito ma tweezers kuti muwone malo olowera.Njirayo ndikukhudza polowera polowera ndi ma tweezers, ndikuwona kuyankha kwa malo olowera.Nthawi zambiri, njirayi imagwiritsidwa ntchito pamayendedwe omvera ndi makanema amplifier (chidziwitso: dera lotentha lapansi ndi dera lalikulu lamagetsi) Osagwiritsa ntchito njirayi, nthawi zambiri amakhala ndi ngozi zamagetsi zamagetsi).

Njirayi imazindikira kuti siteji yapitayi ndi yachibadwa ndipo siteji yotsatira imayankha, choncho cholakwika sichili pa siteji yotsatira, koma pa siteji yapitayi.

Njira yachitatu yothetsera mavuto: ina

Zomwe zili pamwambazi ndi njira zosavuta komanso zolunjika.Kuphatikiza apo, mwachitsanzo, kuwona, kununkhiza, kumvetsera, kukhudza, ndi zina zambiri, zomwe nthawi zambiri zimanenedwa, ndi akatswiri omwe amafunikira chidziwitso kuti athe kuzindikira zovuta.

Kawirikawiri, "yang'anani" sikuti ndiyang'ane momwe zida zoyesera zikuyendera, koma kuti muwone ngati maonekedwe a zigawozo atha;"fungo" makamaka limatanthawuza ngati fungo la zigawo zake ndi lachilendo, monga fungo la moto, electrolyte, ndi zina zotero. Zigawo zambiri zimakhala mu Pamene zowonongeka, zidzatulutsa fungo loyaka moto losasangalatsa.

Ndipo "kumvetsera" makamaka kumvetsera ngati phokoso la bolodi ndi lachilendo pansi pa ntchito;ponena za "kukhudza", sikukhudza ngati zigawozo zili zotayirira, koma kumva ngati kutentha kwa zigawozo ndi kozolowereka ndi dzanja, mwachitsanzo, kuyenera kuzizira pansi pazikhalidwe zogwirira ntchito.Zigawozo ndi zotentha, koma zigawo zotentha zimakhala zozizira kwambiri.Musati muzitsina ndi manja anu mwachindunji panthawi yogwira ntchito kuti dzanja lisatenthedwe ndi kutentha kwakukulu.
