Imimandla yesicelo sezixhobo:
I-Instrumentation inoluhlu olubanzi lwezicelo, ezigubungela ishishini, ezolimo, ezothutho, isayensi kunye neteknoloji, ukhuseleko lokusingqongileyo, ukhuselo lwesizwe, inkcubeko, imfundo kunye nempilo, ubomi babantu kunye neminye imiba.Ngenxa yewonga layo elikhethekileyo kunye nendima enkulu, inefuthe elikhulu eliphinda-phindiweyo nelitsalayo kuqoqosho lwesizwe, kwaye inemfuno entle yemalike kunye namandla amakhulu ophuhliso.
Ukuxilongwa kwempazamo yesixhobo: indlela yile ilandelayo
1. indlela yoxinzelelo lwesandla sokubethwa
Xa sisebenzisa isixhobo, sihlala sidibana nesenzeko sokulungileyo nokubi xa isixhobo sisebenza.Uninzi lwale nto ibangelwa kukudibana kakubi okanye i-welding ebonakalayo.Kule meko, ukucofa kunye nokucofa ngesandla kunokusetyenziswa.
Oko kubizwa ngokuba "kunkqonkqoza" kukucofa ibhodi okanye icandelo kancinci nge-rubber cockroach okanye enye into yokubetha ukuze ubone ukuba iya kubangela impazamo okanye ixesha lokuphumla.Okubizwa ngokuba "uxinzelelo lwesandla" kuthetha ukuba xa kwenzeka iphutha, emva kokucima amandla, cinezela iindawo ezixhunyiwe, iiplagi kunye neesokethi ngokuqinileyo ngesandla kwakhona, uze uqale umatshini kwakhona ukuze uzame ukuba iphoso iya kupheliswa.Ukuba ufumanisa ukuba ukucofa kwi-casing kuyinto eqhelekileyo, kwaye ukuyibetha kwakhona akuqhelekanga, kungcono ukuba uphinde ufake zonke iziqhagamshelo kwaye uzame kwakhona.
2. Indlela yokujonga
Sebenzisa ukubona, ivumba, ukubamba.Ngamanye amaxesha, izinto ezonakalisiweyo ziya kuba nombala, amadyungudyungu okanye amabala atshileyo;amacandelo atshisiweyo aya kuvelisa ivumba elikhethekileyo;iitshiphusi ezimfutshane ziya kuba shushu;i-soldering ebonakalayo okanye i-desoldering nayo inokujongwa ngeliso lenyama.
3. Indlela yokukhuphela ngaphandle
Indlela ebizwa ngokuba yindlela yokuphelisa yindlela yokugweba isizathu sokungaphumeleli ngokufaka ezinye iiplagi kunye nezixhobo kumatshini.Xa isixhobo sibuyela kwisiqhelo emva kokuba iplagi-in board okanye isixhobo sisusiwe, oko kuthetha ukuba iphutha lenzeka apho.
4. Indlela yokutshintsha
Izixhobo ezibini zemodeli efanayo okanye iindawo ezisecaleni ezaneleyo ziyafuneka.Buyisela i-spare elungileyo kunye necandelo elifanayo kumatshini ongalunganga ukuze ubone ukuba impazamo iyacinywa.
5. Indlela yokuthelekisa
Kuyafuneka ukuba nezixhobo ezibini zemodeli efanayo, kwaye enye yazo ikwintsebenzo eqhelekileyo.Ukusebenzisa le ndlela kwakhona kufuna izixhobo eziyimfuneko, ezifana multimeter, oscilloscope, njl Ngokohlobo uthelekiso, kukho uthelekiso ombane, uthelekiso waveform, uthelekiso static impedance, iziphumo uthelekiso isiphumo, uthelekiso lwangoku njalo njalo.
Indlela ethile yile: vumela isixhobo esiphosakeleyo kunye nesixhobo esiqhelekileyo sisebenze phantsi kweemeko ezifanayo, kwaye emva koko ukhangele iimpawu zamanqaku athile uze uthelekise amaqela amabini ezibonakaliso ezilinganisiweyo.Ukuba kukho umahluko, kunokugqitywa ukuba impazamo ilapha.Le ndlela ifuna ukuba abasebenzi bolondolozo babe nolwazi oluninzi kunye nezakhono.
6. ukufudumeza kunye nendlela yokupholisa
Ngamanye amaxesha, isixhobo sisebenza ixesha elide, okanye xa iqondo lobushushu lendawo yokusebenza liphezulu ehlotyeni, liya kungasebenzi kakuhle.Ukuvalwa kunye nokuhlolwa kuqhelekile, kwaye kuya kuba yinto eqhelekileyo emva kokumisa ixesha elithile kwaye kuqaliswe kwakhona.Emva kwexesha elithile, ukungaphumeleli kwenzeka kwakhona.Esi siganeko sibangelwa kukungasebenzi kakuhle kwee-ICs okanye amacandelo, kwaye iiparamitha zeempawu zeqondo lokushisa eliphezulu azihlangabezani neemfuno zesalathisi.Ukuze ufumane isizathu sokungaphumeleli, indlela yokufudumala kunye nokupholisa ingasetyenziswa.
Into ebizwa ngokuba yi-cooling kukusebenzisa i-cotton fiber ukusula i-alcohol e-anhydrous kwindawo enokuthi ingaphumeleli ukupholisa xa ukusilela kwenzeka, kwaye uqaphele ukuba ukusilela kupheliswe.Oko kubizwa ngokuba kukunyuka kwamaqondo obushushu kukwandisa ubushushu be-ambient, njengokusebenzisa intsimbi yokuthambisa yombane ukuya kwindawo ekrokrisayo (lumkele ukunyusa ubushushu buphakame kakhulu ukonakalisa isixhobo esiqhelekileyo) ukubona ukuba impazamo yenzeka.
7. Ukukhwela emagxeni
Indlela yokukhwela igxalaba ikwabizwa ngokuba yindlela ehambelanayo.Beka i-chip ye-IC enhle kwi-chip ukuba ihlolwe, okanye idibanise amacandelo alungileyo (i-resistor capacitors, i-diodes, i-transistors, njl.) ngokuhambelana namacandelo amele ahlolwe, kwaye ugcine uqhagamshelwano oluhle.Ukuba impazamo ivela kwisekethe yangaphakathi evulekileyo yesixhobo okanye Izizathu ezinjengokufowunelwa kakubi kunokulawulwa ngale ndlela.
8. Indlela yokudlula i-Capacitor
Xa isekethe ethile ivelisa into engaqhelekanga, njengokubhideka komboniso, indlela ye-capacitor bypass ingasetyenziselwa ukumisela indawo yesekethe mhlawumbi enempazamo.Xhuma i-capacitor kuwo wonke unikezelo lwamandla kunye nomhlaba we-IC;qhagamshela isekethe ye-transistor kulo lonke igalelo lesiseko okanye isiphumo somqokeleli ukujonga isiphumo sempazamo.Ukuba isenzeko sokungaphumeleli siyanyamalala xa i-terminal yokufaka i-capacitor bypass ayisebenzi kwaye i-terminal yayo yokuphuma igqithiswa, kumiselwa ukuba impazamo yenzeka kweli nqanaba lesekethe.
9. Indlela yokulungelelanisa yombuso
Ngokuqhelekileyo, ngaphambi kokuba impazamo igqitywe, musa ukuchukumisa amacandelo esekethe ngokungaqhelekanga, ngokukodwa izixhobo ezihlengahlengiswayo, ezifana ne-potentiometers.Nangona kunjalo, ukuba amanyathelo aphindwe kabini athathwa kwangaphambili (umzekelo, isikhundla siphawulwe okanye ixabiso le-voltage okanye ixabiso lokumelana lilinganiswe ngaphambi kokuba lichukunyiswe), livumelekile ukuba lichukunyiswe xa kuyimfuneko.Mhlawumbi emva kotshintsho ngamanye amaxesha i-glitch iya kuhamba.
10. Ukuba wedwa
Indlela yokwahlula impazamo ayifuni uhlobo olufanayo lwezixhobo okanye iinxalenye ezisecaleni ukuba zithelekiswe, kwaye zikhuselekile kwaye zithembekile.Ngokuhambelana netshati yokukhangela impazamo, ulwahlulo kunye nokujikeleza ngokuthe ngcembe kucutha uluhlu lokukhangela iimpazamo, kwaye emva koko usebenzisane neendlela ezinjengokuthelekisa umqondiso kunye notshintshiselwano lwecandelo ukufumana indawo enempazamo ngokukhawuleza.
