Maitiro ekudzoreredza wedunhu dhayagiramu ne circuit board?

Kana iwe wawana chigadzirwa, kazhinji yenguva, isu hatina wedunhu dhayagiramu, saka, isu mune ino kesi, maitiro ekuudza musimboti weiyo PCB uye mamiriro ari kushanda, uku ndiko kudzoreredza iwo chaiwo wedunhu schematic diagram.
Paunenge uchisangana nezvimwe zvinhu zvidiki, kana kana paine chinodikanwa, kana uchinge wasangana nemagetsi zvigadzirwa zvisina madhirowa, zvinofanirwa kukwevera iyo wedunhu schematic diagram zvinoenderana nezvinhu. Kunyangwe iri nyaya yechiyero chakati kurei, chinova chakaomarara, asi mushure mekugona mapoinzi anotevera, ndinotenda isu tinogona kuramba tichizviita, redunhu rakareruka, hapana dambudziko.

1. Sarudza vhoriyamu hombe, mapini mazhinji uye unotora chinzvimbo chakakura muzvikamu zvematunhu zvakaita semaseketi akasanganiswa, maTransformer, maTransistor uye zvimwe zvinongedzo zvekudhirowa, uyezve kubva kune akasarudzika mareferensi epini anotanga kudhirowa, anogona kudzikamisa zvikanganiso.
2. Kana bhodhi rePBB rakamakishwa nenhamba yezvikamu zvemanhamba (senge VD870, R330, C466, nezvimwewo), sezvo idzi serial manhamba ane mitemo yakatarwa, izvo zvinongedzo zvine imwechete alphanumeric prefix ndezvimwe zvakafanana zvinoshanda unit, saka vanofanirwa kushandiswa zvine hungwaru mukudhirowa. Zvakanyatso kusiyanisa zvikamu zveiyo imwechete inoshanda unit ndiyo hwaro hwekudhirowa dhizaini.
3. Kana iyo serial nhamba yechinhu isina kunyorwa pabhodhi rakadhindwa, zvirinani kuverenga chikamu kuti zvive nyore kuongorora uye kutarisa dunhu. Kuti tambo yemhangura ipfeke wiring ipfupi, izvo zvikamu zveiyo imwechete inoshanda unit zvinowanzo rongedzwa nenzira yepakati apo mugadziri anogadzira izvo zvikamu zvebhodhi rakadhindwa. Paunenge iwe wawana chishandiso icho chiri pakati peyuniti, unogona kuchitsvaga icho kune zvimwe zvikamu zveiyo imwechete unit.
4. Nyatso kusiyanisa tambo yepasi, tambo yemagetsi, uye tambo yechiratidzo chePREDED bhodhi. Tora magetsi wedunhu semuenzaniso, mugumo wakashata weiyo rectifier chubhu yakabatana neyechipiri magetsi transformer ndiyo yakanaka danda remagetsi, uye iyo tambo yepasi inowanzo kuve yakabatana nehukuru hukuru firita capacitor, uye iyo capacitor ganda iri yakatarwa ne polarity. Unogona zvakare kuwana tambo yemagetsi uye waya wepasi kubva kune matatu-magumo ekugadzirisa pini. Kana wiring yakadhindwa mabhodhi, kuitira kudzivirira kuzvidzora uye kupokana-kupokana, iyo fekitori inowanzo seta yakafararira mhangura foil yepasi waya (yakakwira-frequency dunhu kazhinji ine nzvimbo hombe yevhu mhangura foil), ichiteverwa neyemhangura foil tambo yemagetsi uye yakatetepa yemhangura foil yemutsara wechiratidzo. Uye zvakare, muzvigadzirwa zvemagetsi zvine maseketi eanalogog uye edhijitari, mabhodhi akadhindwa anowanzopatsanura waya dzepasi kuti dziumbe network dzakazvimirira, dzinogona kushandiswa sehwaro hwekuzivikanwa nekutongwa.
5. Kuti tidzivise kuwanda kwakanyanya kwehukama hwemapini kuita wiring yemudunhu dhayagiramu yekuyambuka uye kupindirana, izvo zvinotungamira mukusagadzikana kwekudhirowa, magetsi emagetsi uye waya yepasi anogona kushandisa nhamba hombe yezviratidzo zvekumhara uye zviratidzo zvekumisikidza . Kana paine zvinhu zvakawanda, rimwe nerimwe redunhu rinogona kudhonzwa zvakasiyana uye zvobva zvasanganiswa pamwechete.
6. Iwe unorayirwa kushandisa yakajeka pepa rekutsvagisa mapepa kudhonza tambo dzepasi, tambo dzemagetsi, tambo dzemasaini, uye zvikamu nemuvara uchishandisa multicolor peni. Paunenge uchichinja, zvishoma nezvishoma simbisa iro ruvara kuti riite iro dhizaini riite uye rinotarisa-maziso, kuti uongorore dunhu.
7. Inozivikanwa neyakakosha kuumbwa uye yechinyakare kudhirowa kweimwe mayuniti macircuit, akadai seanogadzirisa zambuko, gadziriro yemagetsi wedunhu uye anoshanda anoshanda, yedhijitari yakasanganiswa wedunhu, nezvimwe. izvo zvinogona kuvandudza kudhirowa kunyatsoshanda.
8. Kana tichidhonza madhiri edunhu, tinofanirwa kuedza nepatinogona napo kutsvaga madhaigiramu edunhu ezvakafanana zvigadzirwa kuti zviongororwe, izvo zvinowana zvakapetwa kaviri nehafu yekuedza.
Iko kushinga pamusoro, kwakakosha pfupiso, ndinovimba iwe muchinhu chekudzidza kune wedunhu dhayagiramu, unogona kutanga kubva pamapoinzi aya, kugona iyi tekinoroji, nekuti ichi ndicho hwaro hwevashandi vemagetsi
