Akukho okukhungathekisayo njengokuzama ukuxhuma idrayivu ye-USB noma igundane bese uqaphela ukuthi imbobo ye-USB yekhompyutha yakho isiyekile. Kungakhathaliseki ukuthi isixhumi sikhululekile ngokomzimba, sisebenza kuphela uma uhambisa ikhebula nge-engeli ethile, noma uhlelo aluboni nokuthi kukhona okuxhunyiwe, Lokhu kwehluleka kuyinto eyenzeka nsuku zonke. ekunakekelweni kwehadiwe.
Izindaba ezinhle ukuthi, nakuba kungase kubonakale sengathi ukuphela komhlaba, iningi lalezi zinkinga lingalungiswa ngaphandle kokulahla ikhompyutha ngefasitela noma ukuchitha imali eningi kubhodi entsha yomama. izilungiselelo ezilula ku-Windows Kusukela ekuhlinzweni ngomshini wokushisela, kunezindlela eziningi zokubuyisela ukusebenza kwamachweba akho nokwandisa isikhathi sokuphila komshini wakho.
Kungani ama-port e-USB eyeka ukusebenza?
Imbangela evame kakhulu, ngaphandle kokungabaza, Ukuguguleka nokuguga ngenxa yokusetshenziswa kakhuluUkufaka nokususa amadivayisi njalo kungagoba noma kuphule amathebhu ensimbi angaphakathi, futhi ingcindezi yomshini ekugcineni iphula amalunga e-solder axhumanisa isixhumi nebhodi lomama. Kuma-PC edeskithophu, ama-port angaphambili asengozini enkulu ngoba avame ukuba nokudlidliza nokugxuma kakhulu kune-port yangemuva.
Kudingeka futhi sicabangele izingozi zikagesi nezendawo ezungezileUkwanda kwamandla kungathosa i-chip yesilawuli se-USB, okwenza i-port ingasebenzi ngisho noma ibonakala ilungile ngokuphelele. Ngakolunye uhlangothi, umswakama, uthuli oluqongelelekile, kanye namafutha kudala izinqubo ezibhubhisayo eziphazamisa ukudluliswa kwedatha, okubangela ukuxhumana okungenasikhathi noma okungekho nhlobo.
Izinyathelo zokuthola ukuxilongwa okunembile
Ngaphambi kokuthi ukhiphe insimbi yokunamathisela, udinga ukudlala njengomseshi ukuze uthole inkinga. Okokuqala, susa inkinga engaphandle kwe-peripheral; zama idivayisi kwenye ikhompyutha noma uhlole ukuthi unayo yini. Imemori ye-USB ayibonwaUma inkinga iqhubeka echwebeni, ukuhlolwa okubonakalayo ngengilazi yokukhulisa noma i-microscope Kubalulekile ukuthola amaphini agobile, ukungcola okufakwe ngaphakathi, noma amalunga e-solder aqhekekile.
Ezingeni le-elekthronikhi, ukusetshenziswa kwe-multimeter kukuvumela ukuthi uhlole ukuqhubeka kukagesi phakathi kwembobo nebhodi. Uma idivayisi ithola ugesi (izibani ziyakhanya) kodwa ingadlulisi idatha, inkinga ivame ukuba kumaphini 2 no-3. Uma kungekho ugesi, iphutha lingaba kumaphini 1 (ugesi we-5V) noma kumaphini 4 (phansi). Ezimweni eziyinkimbinkimbi kakhulu, ama-oscilloscope asetshenziswa ukuhlaziya ukuthi izimpawu zedatha zifinyelela kumlawuli ngendlela efanele.
Izixazululo zesofthiwe nokucushwa
Ngezinye izikhathi ihadiwe ayisebenzi futhi imbangela yisistimu yokusebenza. Ku-Windows 10 noma 11, kuvamile kakhulu ku- Izilawuli ze-USB host yonakaliswe. Isixazululo esisebenzayo ukuya ku-Device Manager, ukhiphe abashayeli be-Universal Serial Bus, bese uqala kabusha ikhompyutha yakho, ikakhulukazi uma ufuna Kungani iWindows ingayiboni idrayivu ye-USB? nokuthi ungayilungisa kanjani.
Enye inkinga evamile Ukumisa okwesikhashana okukhethiwe kwe-USBI-Selective Sleep iyisici sokonga amandla esivala imbobo ukuze kongiwe ibhethri, ikakhulukazi kuma-laptop. Lokhu kungalungiswa ngokushintsha izilungiselelo zamandla ezithuthukisiwe ku-Control Panel kanye nokukhubaza i-selective sleep. Ngisho noma kungekho kulokhu okusebenzayo, i- Ukusetha kabusha kwe-BIOS noma i-UEFI Ingabuyisa ama-port akhutshazwe ngengozi ezingeni le-firmware.
Ukulungiswa ngokomzimba kanye namasu okuhlanganisa i-microsoldering
Uma umonakalo ungowomshini, singena emkhakheni we-elekthronikhi. Uma imbobo ikhululekile, kudingeka isiteshi somoya oshisayo ukuze kususwe isixhumi esonakele ngaphandle kokulimaza izinsalela zethusi. Kubalulekile ukusebenza nge amazinga okushisa alawulwayo (ngokuvamile phakathi kuka-310°C no-350°C) bese usebenzisa i-flux ukuqinisekisa ukuthi i-solder joint ihlanzekile futhi iqinile.
Ezimweni lapho ichweba likhiphe khona imikhondo ebhodini le-motherboard, ukwakhiwa kabusha ngocingo lwethusi oluhlanganisiweLe nqubo ihilela ukudala ngesandla ibhuloho kusuka ku-connector pin kuya endaweni elandelayo esebenzayo kusekethe. Uma kwenzeka ukwehluleka kwe-controller chip, ikhambi... ukuphinda kufakwe noma kushintshwe isekethe ehlanganisiwe ye-BGA, umsebenzi onembile kakhulu odinga imishini ekhethekile ukuze kugwenywe ukuguguleka kwe-PCB.
Ukulungiswa ukuze kuvinjelwe ukuwohloka kwesikhathi esizayo
Ukuze uvimbele lokhu kungenzeki futhi, kungcono ukugwema ukuphoqa isixhumi futhi ungashiyi izintambo ze-USB zilenga ezingasicindezela. voltage regulators Ivikela izingxenye zangaphakathi ekukhuphukeni kwamandla okungalimaza abalawuli. Ngaphezu kwalokho, ukuhlanza njalo ngomoya ocindezelwe kuvimbela i-lint eqongelelekile ekubangeleni ama-short circuits noma ukuxhumana okungenazikhawu.
Khumbula ukuthi ukulungisa isixhumi kuvame ukubiza kancane ngo-80% kunokushintsha ibhodi lonke, ngaphezu kokuvimbela ukulahleka kwedatha nokunciphisa imfucuza kagesi. Isihluthulelo siku- ungaphoqi ichweba uma iqala ukwehluleka, njengoba umonakalo omncane endaweni yokuhlanganisa insimbi kulula kakhulu ukuwulungisa kune-trace yethusi ekhishwe ngokuphelele.
Ukubuyisela uxhumano lwe-USB kuhilela ukuhlaziywa okunengqondo okuqala ngokuhlanza nokuhlola abashayeli, okukhuphukela ekungeneleleni ngokomzimba nge-microsoldering uma umonakalo ungowesakhiwo. Kungakhathaliseki ukuthi ngokwenza ngcono ukuphathwa kwamandla ku-Windows noma ukwakha kabusha ama-trace alimele kubhodi lomama, kungenzeka ukubuyisela ukusebenza kunoma iyiphi idivayisi, ukugwema izindleko ezingadingekile kwihadiwe entsha nokubeka phambili ukulungiswa kobuchwepheshe okukhethekile.
