Akunabo bonke abathengisi abadalwa ngokulinganayo - nganye i-solder ifanelekile kwiindawo ezininzi zokushisa nezicelo. Ukukhetha i-solder efanelekileyo kubalulekile ukufumana uxhulumano olufanelekileyo lombane oluya kugcina ubomi besiphaluka kwaye lube yinto yokuhluleka .
Iintlobo zeSolder
I-solder yombane ngokubanzi iwela kwenye yeentlobo zintathu, i-solder ekhokelayo, i-solder engenakukhokelela okanye i-solder yesilivere. I-solder-based solder is solder eyenziwa kwi-alloy ye-tin kunye nekhokelo, ngamanye amaxesha nezinye iimboni kunye. Isizathu sokukhokelela sidibene ne-tin kukuba i-alloy ephumela ekubeni ineqondo lokubilisa ukunyuka kwexabiso, into ephambili yokuxutywa xa iindawo ezininzi ze-elektroniki zibuhlungu kakhulu! I-solder ye-alloy ekhokelayo isoloko ibhekiswe kwisilinganiselo sayo se-alloy efana ne-60/40 okanye 63/37, kunye nenombolo yokuqala ibe yitini ngokulinganisa kwaye inombolo yesibini iyinani lokukhokelwa ngesisindo. Zombini ezi zi-alloys eziqhelekileyo zilungile kwi-electronics evamile, kodwa 63/37 yi-alloy eutectic, oku kuthetha ukuba unenguqu olubukhali phakathi kwamanzi kunye nolomeleleyo njengoko kutshintsha kweqondo lokushisa. Le propati inceda ukunciphisa amajoyina angamaqabunga abonakalisiweyo angenzeka xa inxenye ihamba njengoko i-solder ipholisa.
I-solder ye-alloy ekhokeleyo yinto e-standard-solder esebenzisa i-electronics kwiminyaka emashumi, kodwa ngenxa yemicimbi yezempilo ehambelana nokukhokela, siye saqala ukuhamba ukusuka kubathengisi abahamba phambili . IYurophu ibangela indlela ekunciphiseni ukukhokela ngokudlula ukuNciphisa kweeMpawu eziMngcipheko (RoHS) kunye neNkunkuma yeMbane kunye neElectronike (WEEE) eyanciphisa inani lokukhokela kuyo nayiphi na into ukuya ku-0.1%. Enye yezona alloys ezithandekayo ezingenazikhokelo zi-96.5 / 3 / 0.5 i-alloy ene-96.5% ye-tin, i-3% yesilivere, kunye no-0.5% ithusi. Ngelishwa, amaninzi ama-alloys angenakukhokelela ayabiza kunokuba abathengisi be-alloy ehamba phambili, bancibilike kwiqondo lokushisa eliphezulu kwaye ngaloo ndlela badinga ukufudumala kweqondo lokushisa, kwaye banikezela ngamandla, kodwa amaninzi amaninzi. Ukusetyenziswa kwexesha elide le-alloy e-solder esingaqhubekiyo kungasetyenzwa, nangona ezinye iziphumo ezinjenge-whiskers kunye ne-soldering iron ingubo sele sele zichongiwe njengefuthe lexesha elide le-electronics.
I-solder ye-alloy isiliva ingaba yinkokeli okanye idibene nekhokelo. Isilivere yongezwa okokuqala ekukhokheni i-alloy solder ekhuselekileyo isithintelo sokuthi ukufuduka kwesilivere xa kuthe kwavela izinto zesilivere. Nge-solder ekhokhelwayo ekhokelayo, isilivere kwisiqulatho sesilivere iya kuphuma kwi-solder kwaye ibangela ukuba i-solder ihlangane ibe yinto ephosakeleyo kwaye ilungele ukuphula. I-alloy lead Leader nge silivere, njenge-62/36/2 i-solder ne-2% yesilivere, i-62% yeetoni kunye no-36% okhokelayo, umda wesiqhamo sesizwe sokufuduka kunye neendawo ezibhetele kuzo zonke i-solder, ukwanda kwindleko.
Ukukhetha iSolder Right
Uninzi lweempawu ezahlukeneyo lunokwenza ukhetho olufanelekileyo lwe-solder. I-solder efanelekileyo ifuna ukungena kwi-akhawunti ekuthengiswe kuyo, ukusetyenziswa kwe-flux , ubukhulu beendawo ezithengiswayo, kunye nemiba yempilo kunye nokukhuseleka kwe-soldering.
I-Solder iyatholakala ngaphandle kweyodwa, enye okanye i-rosin (i-flux) yeebhola ezihambayo zihamba phakathi kwinqanaba le-wire solder. Olu luhlu lwe-rosin flux luyakusiza ukuhamba kwe-solder kunye nentambo kwiindawo ezithengiswayo, nangona kunjalo, ngamanye amaxesha i-rosin flux efakwe kwi-solder ayifuneki ngenxa yezizathu ezininzi, njengendlela yokucoca ekufuneka isetyenziswe emva kwe-soldering okanye ubukho be-asidi eqinekileyo ye-acid (njenge-solder-flux solder esetyenziswe kwi-plumbing engazange isetyenziswe kwi-electronics) kwaye i-flux ehlukeneyo ifaneleka.
I-Solder iyafumaneka nakwii-diameter, kunye ne-0.02 ", i-0.063" kunye ne-0.04 "ibe yinto eqhelekileyo ye-solder diameter. kunzima kakhulu. Le yilapho i-0.02 "kunye ne-0.04" i-solder iba luncedo kakhulu. Ngokubanzi, uninzi msebenzi ungenziwa ngo-0.04 "ubude be-solder, ngakumbi xa kudibaniswe namava ambalwa kunye nokuhamba okufanelekileyo.
