I. Izici zebhodi lesifunda elinamacala amabili
Umehluko phakathi kwamabhodi wesifunda anezinhlangothi ezimbili namabili yinani lezingqimba zethusi.
Ibhodi lesifunda elinamaceleni amabili liyibhodi lesifunda elinethusi ezinhlangothini zombili, elingaxhunywa ngezimbobo.Futhi kukhona ungqimba olulodwa kuphela lwethusi ohlangothini olulodwa, olungasetshenziselwa imigqa elula kuphela, futhi izimbobo ezenziwe zingasetshenziselwa kuphela i-plug-in kodwa hhayi ukuqhuba.
Izidingo zobuchwepheshe zebhodi lesifunda elinezinhlangothi ezimbili ziyi-wiring density, indawo yokuvula incane, futhi ukuvuleka komgodi we-metalized kuncane futhi kuncane.Ukuxhumana kwesendlalelo kuya kungqimba kuncike kukhwalithi yembobo eyenziwe ngensimbi, ehlobene ngokuqondile nokwethembeka kwe-PCB.
Ngokuncishiswa kwembobo, okwangempela akunawo umthelela emfucumfucwini emikhulu yokuvula indawo, njengemfucumfucu yebhulashi, umlotha wentaba-mlilo, uma ushiywe emgodini ongaphakathi, uzokwenza imvula yamakhemikhali yethusi, i-copper Plating ilahlekelwe umphumela, ayikho imbobo yethusi. , abe umbulali obulalayo we-hole metallization.
II.Ibhodi lesifunda elinamaceleni amabili ukuze kuqinisekiswe ukuthi isifunda esinezinhlangothi ezimbili sinomphumela othembekile wokuqhuba, kufanele kuqala sisebenzise izintambo nokunye ukushisela imbobo yokuxhuma kuphaneli ephindwe kabili (okungukuthi, inqubo ye-metalization ngokusebenzisa ingxenye yembobo), futhi ukusika ithiphu yomugqa wokuxhuma ingxenye ephumayo, ukuze ungalimazi isandla sika-opharetha, leli ibhodi lokulungiselela izintambo.
III.Geza kabusha ihhaviniizinto zokushisela:
1. Ukucubungula inqubo kuzokwenziwa ngokuya ngezidingo zemidwebo yenqubo yamadivayisi adinga ukubunjwa;Okusho ukuthi, ngemuva kwe-plug-in yokuqala yepulasitiki.
2. Ngemuva kokubunjwa, ubuso bemodeli be-diode kufanele buphakame, futhi ubude bezikhonkwane ezimbili akufanele bungahambisani.
3. Uma idivayisi enezidingo ze-polarity ifakiwe, qaphela i-polarity akufanele ifakwe emuva, futhi izingxenye zebhulokhi ezihlanganisiwe ze-roller, ngemva kokufakwa, noma ngabe idivayisi eqondile noma e-recumbent, ngeke ibe nokutsheka okusobala.
4. Amandla ensimbi kagesi asetshenziselwa ukushisela aphakathi kuka-25 ~ 40W, izinga lokushisa lekhanda lensimbi kagesi kufanele lilawulwe cishe ku-242 deG C, izinga lokushisa liphezulu kakhulu ikhanda kulula "ukufa", izinga lokushisa iphansi kakhulu ukuncibilikisa i-solder, isikhathi sokushisela silawulwa ngemizuzwana engu-3 ~ 4.
5. Welding esisemthethweni ngokuhambisana idivayisi kusukela phezulu kuya phezulu, kusukela ngaphakathi kuya ngaphandle isimiso Welding ukusebenza, Welding isikhathi master, isikhathi eside kakhulu kuyoba hot idivayisi embi, uyophinde kube hot yethusi camera ngocingo phezu. ipuleti yethusi camera.
6. Ngenxa yokuthi i-welding kabili emaceleni, ngakho-ke kufanele futhi yenze uhlaka lwenqubo yokubeka ibhodi lesifunda, ukuze ungacindezeli idivayisi ngezansi.
7. ngemva kokuphothulwa welding ibhodi wesifunda kufanele kwenziwe isheke olunzulu uhlobo lokumaka, hlola ukuvuza Welding indawo, uqinisekise ibhodi wesifunda ngemva iphinikhodi redundant idivayisi, ngemva ogeleza singene inqubo elandelayo.
8. In the operation ethize, kufanele futhi ngokuqinile ukulandela imigomo efanele inqubo ukusebenza, ukuqinisekisa izinga Welding imikhiqizo.
Ngokuthuthuka okusheshayo kobuchwepheshe obuphezulu, imikhiqizo ye-elekthronikhi ehlobene eduze nomphakathi ivuselelwa njalo, umphakathi nawo udinga ukusebenza okuphezulu, usayizi omncane, imikhiqizo ye-elekthronikhi enemisebenzi eminingi, ebeka phambili izidingo ezintsha zebhodi lesifunda.
