Ndiyakuthanda ukudala umxholo okhululekileyo ogcwele iingcebiso kubafundi bam, wena. Andilwamkeli uxhaso oluhlawulelweyo, uluvo lwam lolwam, kodwa ukuba ufumanisa ukuba izindululo zam ziluncedo kwaye ugqibela ngokuthenga into oyithandayo ngenye yeekhonkco zam, ndingafumana ikhomishini ngaphandle kwendleko ezongezelelweyo kuwe. Funda nzulu
I-Soldering intle kakhulu ngokusisigxina. Kodwa nangona kunjalo, unokuphinda usebenzise isolder okt we-remover solder usebenzisa impompo ye-desoldering pump kunye ne-iron soldering. Kodwa iyakhohliseka xa ungenayo le kwaye ufuna ukungxama ngokukhawuleza.
Kule posi siza kugubungela:
Sebenzisa i-Flat Head Screwdriver
Iscrewdriver sesona sixhobo sixhaphakileyo esinokufunyanwa nakweyiphi na izixhobo. Nangona zenzelwe ukujoyina, singazisebenzisela injongo echaseneyo nazo. Ngokufanelekileyo, i-screwdriver yentloko ethe tyaba lukhetho kwindawo enkulu yentloko. Ngapha koko, la manyathelo ambalwa anokubakhokelela kwenye indlela efanelekileyo.Inyathelo 1: Hlikihla iNgcebiso
Bamba iscrewdriver sentloko esicabalele kwaye uthambise intloko ngesiqwengana selaphu elicocekileyo nelomileyo. Oko kuyakuqinisekisa ukuba akusekho oxide okanye irusi kwicandelo eliyintloko. Nantsi ingcebiso! Khetha eyona screwdriver indala kwizixhobo zakho. Njengoko i-screwdriver iya kutshiswa kakhulu kwaye kamva ipholile, ihlala icinywa.
Inyathelo 2: Yifudumeze
Ukufudumeza i-screwdriver, itotshi yepropane lolona khetho lufanelekileyo. Inokudala ilangatye ukuya kuthi ga kwi-2000 ukuya kwi-2250 degrees Fahrenheit. Ngokungafaniyo itotshi esetyenziselwa ukutshiza imibhobho yobhedu, itotshi yepropane ivelisa ilangatye elinombala ngakumbi. Ngqo bamba screwdriver kwilangatye le itotshi ulinde de intsimbi ijike ibe bomvu phantse. Yenza le nyathelo ngokusondeleyo kwexesha kwi-soldering.
Inyathelo 3: Nyibilikisa iSolder ezantsi
Ngoku lifikile ixesha lokuchukumisa i-solder ngencam ye-screwdriver eshushu. Kodwa kufuneka ulumke kakhulu ukufaka ubushushu kuphela kwilungu le-solder oyifunayo, hayi ezinye iinxalenye zesekethe. Indawo ethe tyaba ngokupheleleyo lelona liqabane lililo kulo msebenzi. Qinisekisa ukuba i-PCB ibekwe ngokulinganayo phezu komhlaba. Emva koko zama ukufumana indawo ephezulu ye-solder okanye i-bubble. Ukuchukumisa okuthambileyo kwanele ukwenza unxibelelwano oluyimfuneko phakathi kwencam ye-screwdriver kunye nebhola. Emva kwexesha cinezela ezantsi kwaye i-solder eqinileyo iya kuqala ukunyibilika.
Inyathelo 4: Susa iSolder
Nje ukuba uyinyibilikise ngempumelelo i-solder, kuya kufuneka uyisuse ngokufanelekileyo kwi-PCB. Kwakhona, i-screwdriver iyasihlangula! Bamba iscrewdriver ekufuneka ubukhulu becala siphole ngoku kwaye siyichukumise nge-solder. Kungekudala i-solder iya kubambelela kwi-screwdriver. Ungasebenzisa enye i-screwdriver ukuba eyangaphambili ayinakulunga ngokwaneleyo.
Inyathelo 5: Khuhla iNgcebiso
Phinda uthabathe itotshi yepropane uyitshise. Bamba i-screwdriver kwilangatye. Emva koko khuhla umphezulu ngelaphu. Yiyo loo nto i-solder eseleyo kumphezulu wescrewdriver inokucocwa ngokufanayo indlela ococeka ngayo i-iron soldering.
Ukuhlangula iiComputer ezinobuthathaka kwiisekethe zombane
Unako ngokuqinisekileyo susa i-solder kuyo nayiphi na i-PCB ngale ndlela sele ikhankanyiwe. Kodwa kukho iindlela ezithile. Obo bushushu ubufaka ebhodini bunokonakalisa ezinye izinto ezibuthathaka kwibhodi. Kungenxa yoko le nto kukho into efunekayo enokususa ngokukhuselekileyo izinto. Nangona kwezi nkqubo, ubushushu buyimfuneko. Kodwa ezinye iindlela zisetyenziselwa ukugcina ubushushu kwaye zibeka bucala iindawo ezingqongileyo.
1. Ngokufudumeza iTheminali enye
Akunyanzelekanga ukuba ushushu zonke iiterminal zecandelo ngexesha. Unokufaka ubushushu nganye nganye. Obu buchule busebenza ngakumbi xa kufuneka ujongane nezinto ezinobunkunkqele. Isinyithi samanzi esisezantsi singasetyenziselwa ukubonelela ubushushu. Ngaphandle koko, ukufaka isinki yokufudumeza kufutshane necandelo kunokusebenza kakhulu ekususeni ubushushu obungafunekiyo.
2. Sebenzisa umpu womoya oshushu kunye nempompo yokufunxa
Umpu womoya oshushu unokuvuthela umoya oshushu kwi-PCB kwaye ekugqibeleni unokwenza ukuba i-solder ishushu ngokwaneleyo. Sebenzisa umpu womoya oshushu yeyona ndlela yobuchule yokugqiba umsebenzi. Kodwa aba bantu badla ngokwandisa ezinye izinto zesekethe kwisekethe. Kungenxa yoko le nto ukusebenzisa i-nitrogen gas kukhuselekile. Nangona ezi zixhobo zinokuvuthela umoya oshushu kumalungu kodwa i-solder ekhupha i-PCB kufuneka isuswe. Impompo yokutsala eyilelwe ngokukodwa okanye i-solder sucker iyafuneka ukususa i-solder ngokukhuselekileyo. Ukusebenzisa ezi zixhobo kuya kuqinisekisa ukuba akukho candelo lichukumisiweyo okanye akukho kuvalwa okungafunekiyo kwe-solder eyenzekayo.
3.Ukusebenzisa iiphakheji ze-Quad Flat ukususa iiNxalenye eziethe-ethe
Ukuba ufuna ukugcina i-IC kwi-PCB, akukho sizathu sisebenzisa i-iron soldering ngqo. Ewe, awukwazi ukufudumeza zonke iiterminal ze-IC kwangoko ngentsimbi. Nokuba usebenzisa umpu womoya oshushu ngokungakhathali awunako ukuzisa iziphumo ezifunwayo. Kule meko, kuya kufuneka usebenzise iphakheji yeflethi. Ulwakhiwo olusisiseko lweQFP lulula. Inezikhokelo ezincinci ezixinene ngokudibeneyo kunye neendonga ezibhityileyo ezine ezisebenza njengesifudumezi sobushushu. Inenkqubo yasentwasahlobo ebambe i-IC inyukele phezulu kwangoko nje ukuba i-solder ifike kwimeko engamanzi. Emva kokumisela ngokufanelekileyo i-QFP, kuya kufuneka uvuthele umoya oshushu ukusuka kumpu womoya oshushu. Njengokuba ubushushu bubambeka kwindawo oyifunayo yeendonga ezincinci, i-solder kuloo ndawo ifumana ubushushu ngokukhawuleza. Kungekudala ukhululekile ukutsala i-IC usebenzisa isixhobo sokukhupha. Ezinye i-QFC zineepadding ezongeziweyo ezikhusela ezinye izinto zesekethe ekubeni zibekwe zodwa.
Indlela yeBrute Force
Ukuba ucinga ukuba i-PCB indala ngokwaneleyo kwaye ayinakuphinda isebenzise enye, unokusebenzisa ubuchule obunamandla obunokukunceda ekulondolozeni izinto. Zijonge!1. Sika iiTheminali
Unokusika iiterminal zezinto ezingafunekiyo kwaye uzikhuphe. Sebenzisa i-blade blade kulo msebenzi. Ngaphandle koko, i-vice-grip inokunceda kakhulu ukuphula i-solder bond kunye nokukhupha icandelo. Kodwa lumka isandla sakho ngelixa usebenzisa amandla. Kungcono ukunxiba iiglavu.
2. Ukucofa okomeleleyo nakweyiphi na iFlethi engaphezulu
Oku kunokubonakala ngathi kukuhlekisa kodwa ukubetha ibhodi kwindawo enzima lukhetho lokugqibela lokwaphula indibaniselwano ye-solder. Ukuba awuyidingi ibhodi kodwa izinto nje, ungaya kolu buchule. Ukutshatyalaliswa ngamandla kwempembelelo kunokuphula i-solder kwaye kubangele ukuba icandelo likhululeke.
Okukwintsusa
Okwangoku uyazi indlela yokususa i-solder ngaphandle kwentsimbi ye-soldering. Ayisiyo nut enzima yokuqhekeka. Nokuba kwezinye iimeko ukusebenzisa i-iron soldering akukhuselekanga. Kodwa khumbula nayiphi na indlela oyithathayo, soloko uqinisekisa ukuba usebenza kwindawo ethe tyaba kwaye awuyichukumisi into yokunyibilika ngesandla.
