Okokuqala, iqhinga elincinci lokuvavanya i-multimeter yokuvavanya amacandelo e-SMT
Amanye amacandelo e-SMD mancinci kakhulu kwaye akunzima ukuvavanya kunye nokulungiswa ngeepeni eziqhelekileyo ze-multimeter. Enye kukuba kulula ukubangela isiphaluka esifutshane, kwaye enye yinto engathandekiyo kwibhodi yesekethe ehlanganiswe ne-insulating coating ukuze ichukumise inxalenye yentsimbi yepini yecandelo. Nantsi indlela elula yokuxelela wonke umntu, iya kuzisa lula kakhulu ekubhaqweni.
Thatha iinaliti ezimbini ezincinci zokuthunga, (i-Deep Industrial Control Maintenance Technology Column), zivale kwi-multimeter pen, emva koko uthathe ucingo olucekeceke lobhedu olusuka kwintambo ye-multi-strand, kwaye ubophe inaliti kunye nenaliti ukuya kunye, sebenzisa i-solder solder ngokuqinileyo. Ngale ndlela, akukho mngcipheko wesiphaluka esifutshane xa ulinganisa ezo zixhobo ze-SMT ngepeni yokuhlola enencam yenaliti encinci, kunye nencam yenaliti inokugqobhoza i-insulating coating kwaye ibethe iindawo eziphambili ngokuthe ngqo, ngaphandle kokukhathazeka ngokukhuhla ifilimu. .
Okwesibini, indlela yokugcinwa kwebhodi yesekethe yonikezelo lwamandla kawonkewonke impazamo yesiphaluka
Kugcino lwebhodi yesekethe, ukuba udibana ne-short-circuit yonikezelo lwamandla kawonke-wonke, impazamo idla ngokunzulu, kuba izixhobo ezininzi zabelana ngombane ofanayo, kwaye zonke izixhobo ezisebenzisa lo mbane zirhanelwa ukuba zifutshane. Ukuba akukho zixhobo ezininzi ebhodini, sebenzisa "i-hoe umhlaba" Emva kwakho konke, unokufumana inqaku le-short-circuit. Ukuba kukho amacandelo amaninzi, kuya kuxhomekeka kwithamsanqa "ukugawula umhlaba" ukufikelela kwimeko. Indlela esebenzayo ngakumbi iyacetyiswa apha. Ukusebenzisa le ndlela kuya kufumana isiphumo esiphindwe kabini ngesiqingatha somzamo kwaye kaninzi sifumana iphoso ngokukhawuleza.
Kuyimfuneko ukuba ube nombane ombane oguquguqukayo kunye nokhoyo, i-voltage 0-30V, i-0-3A yangoku, lo mbane awubizi, malunga ne-300 yuan. Lungisa umbane ovulekileyo wesekethe kwinqanaba lonikezelo lwamandla ombane wesixhobo, qala ulungelelanise langoku ukuya kubuncinci, yongeza lo mbane kwindawo yobonelelo lwamandla ombane wesekethe, njengeetheminali ze-5V kunye ne-0V ze-chip yochungechunge lwama-74, ngokuxhomekeke kumbane. iqondo lesekethe emfutshane, ngokucothayo wongeza umsinga. Bamba isixhobo ngesandla. Xa uchukumisa isixhobo esitshisa kakhulu, oku kudla ngokuba yinxalenye eyonakalisiweyo, enokususwa ukuze kulinganiswe ngakumbi kunye nokuqinisekiswa. Ngokuqinisekileyo, i-voltage akufanele idlule umbane osebenzayo wesixhobo ngexesha lokusebenza, kwaye uxhumano alukwazi ukuguqulwa, ngaphandle koko luya kutshisa ezinye izixhobo ezilungileyo.
Isithathu. Irabha encinci inokusombulula iingxaki ezinkulu
Iibhodi ezininzi ngakumbi zisetyenziselwa ulawulo lwamashishini, kwaye iibhodi ezininzi zisebenzisa iminwe yegolide ukufaka kwiindawo zokubeka. Ngenxa yobume bendawo yemizi-mveliso erhabaxa, enothuli, efumileyo, kunye nerhasi eyonakalisayo, ibhodi inokuba nokusilela konxibelelwano. Abahlobo banokuthi basombulule ingxaki ngokutshintsha ibhodi, kodwa iindleko zokuthenga ibhodi zikhulu kakhulu, ngakumbi iibhodi zezinye izixhobo ezithunyelwa ngaphandle. Enyanisweni, ungasebenzisa into yokucima ukuhlikihla umnwe wegolide amaxesha amaninzi, ucoce ukungcola kumnwe wegolide, kwaye uzame umatshini kwakhona. Ingxaki ingasonjululwa! Indlela ilula kwaye iyasebenza.
Okokuqala. Uhlalutyo lweempazamo zombane ngamaxesha amahle kunye namaxesha amabi
Ngokumalunga nokunokwenzeka, iziphene ezahlukeneyo zombane ezinamaxesha alungileyo namabi ziquka ezi meko zilandelayo:
1. Uqhagamshelwano olubi
Uqhagamshelwano olubi phakathi kwebhodi kunye ne-slot, xa intambo iphukile ngaphakathi, ayiyi kusebenza, iplagi kunye ne-wiring terminal ayidibanisi, kwaye amacandelo athengiswa.
2. Umqondiso uphazamisekile
Kwiisekethe zedijithali, iimpazamo ziya kubonakala kuphela phantsi kweemeko ezithile. Kungenzeka ukuba ukuphazamiseka okukhulu kuchaphazele inkqubo yokulawula kwaye kubangele iimpazamo. Kwakhona kukho utshintsho kwiiparameters zecandelo ngalinye okanye iiparitha zokusebenza ngokubanzi zebhodi yesekethe ukukhusela ukuphazamiseka. Ikhono lityekele kwinqanaba elibalulekileyo, elikhokelela ekungaphumeleli;
3. Uzinzo olubi lwe-thermal lwamacandelo
Ukususela kwinani elikhulu leendlela zokulondoloza, ukuzinza kwe-thermal ye-electrolytic capacitors ngowokuqala ukuba yintlupheko, ilandelwa ngamanye ama-capacitors, i-triodes, i-diodes, i-IC, i-resistors, njl.;
4. Ukufuma kunye nothuli kwibhodi yesekethe.
Ubumanzi kunye nothuli luya kuqhuba umbane kwaye lube nefuthe lokuchasa, kwaye ixabiso lokumelana liya kutshintsha ngexesha lenkqubo yokwandiswa kwe-thermal kunye nokunciphisa. Eli xabiso lokuchasana liya kuba nefuthe elihambelanayo namanye amacandelo. Xa esi siphumo sinamandla, siya kutshintsha iiparamitha zesekethe kwaye kubangele ukungasebenzi kakuhle. yenzeka;
5. Isoftware yenye yezinto eziqwalaselwayo
Iiparamitha ezininzi kwisekethe zihlengahlengiswa ngesoftware. Imida yezinye iiparamitha zihlengahlengiswa phantsi kakhulu kwaye zikuluhlu olubalulekileyo. Xa iimeko zokusebenza zomatshini zidibana nezizathu zesofthiwe ukucacisa ukungaphumeleli, ngoko i-alamu iya kuvela.
Okwesihlanu, indlela yokufumana ngokukhawuleza ulwazi lwecandelo
Iimveliso ze-elektroniki zanamhlanje ziyahlukahlukana, kwaye iintlobo zamacandelo ziya zihluka ngakumbi. Ekugcinweni kweesekethe, ngokukodwa kwintsimi yokugcinwa kwebhodi yesekethe yezoshishino, amaninzi amacandelo angabonakali okanye angabonakali. Ukongeza, nokuba ulwazi lwamacandelo ebhodini elithile lugqityiwe, Kodwa ukuba ufuna ukukhangela kwaye uhlalutye ezi datha nganye nganye kwikhompyuter yakho, ukuba akukho ndlela yokukhangela ngokukhawuleza, ukusebenza kakuhle kokugcinwa kuya kuncitshiswa kakhulu. Kwicandelo lokugcinwa kwe-elektroniki kwimizi-mveliso, ukusebenza kakuhle yimali, kwaye ukusebenza kakuhle kuyafana nemali yepokotho.
