Yuav ua li cas koj to taub lub soldering ntawm hluav taws xob soldering hlau
Vuam yog txheej txheem ntawm soldering tsim nyog Cheebtsam rau ib tug luam Circuit Court board los yog xaiv qhov chaw raws li xav tau. Thaum vuam, nws yog ib qho tsim nyog los tswj qhov kub thiab txias lub sij hawm vuam ntawm cov hluav taws xob soldering hlau. Yog tias qhov kub thiab txias qis dhau los yog lub sijhawm luv luv, lub tin saum npoo yuav muaj burrs zoo li tus Tsov tus tw, qhov saum npoo yuav tsis du, thiab txawm tias zoo li tofu residue. Nws yog tau hais tias vim tsis tiav evaporation ntawm lub soldering flux, muaj ib tug tej yam npaum li cas ntawm flux tshuav ntawm lub soldering tin thiab hlau. Tom qab txias, lub soldering flux (rosin) yuav lo lub soldering tin rau cov hlau nto, thiab nws muaj peev xwm rub tau qhib nrog me ntsis quab yuam, uas yog hu ua cuav soldering.
Tsis tas li ntawd, thaum qhov kub ntawm cov hluav taws xob soldering hlau yog tsawg heev, nws yog ib qho tseem ceeb rau welding nws. Lub tin ntawm qhov taw tes soldering melts maj mam, thiab cov khoom siv soldered tuaj rau hauv kev sib cuag nrog cov hlau soldering ntev dhau lawm, uas tuaj yeem ua rau kub dhau mus rau cov khoom, ua rau cov khoom puas (xws li melting ntawm capacitor ntim, hloov. ntawm resistor kuj vim thermal kuj, thiab lwm yam), tshwj xeeb tshaj yog rau transistors. Thaum cov tub ntxhais tub ntxhais yog cua sov tshaj 100 degree, nws yuav puas.
Ntawm qhov tsis sib xws, yog tias qhov kub ntawm cov hluav taws xob soldering hlau siab dhau lawm thiab lub sijhawm vuam ntev dua me ntsis, nws yuav ua rau oxidation ntawm cov hlau nplaum, cov hlau ntws yuav tawg, thiab cov hlau sib txuas yuav tsis noj txaus tin. Tsuas yog ib qho me me ntawm cov solder yuav txuas cov khoom sib txuas ua rau cov hlau nto, ua rau muaj kev tiv thaiv siab thiab tawg thaum rub, uas yog hu ua virtual soldering. Hauv qhov xwm txheej hnyav, nws tseem tuaj yeem ua rau cov ntawv ci tooj liab ntawm lub rooj tsav xwm luam tawm kom curl thiab poob tawm, thiab cov khoom yuav raug puas vim overheating.
Txawm hais tias qhov ntsuas kub ntawm lub tshuab hluav taws xob hluav taws xob yog qhov tsim nyog tuaj yeem txiav txim siab raws li kev paub raws li qhov ntev ntawm lub sijhawm soldering ntawm lub taub hau hlau thiab cov nyiaj ntawm cov khoom txuas nrog lub taub hau. Lub sijhawm vuam ntev yuav tsum xyuas kom meej tias cov pob qij txha yog du thiab ci, feem ntau yog 2-3 vib nas this, thiab cov pob qij txha loj dua yuav tsum tsis pub tshaj 5 vib nas this. Soldering transistors thiab lwm yam tsis zoo, tseem zoo li thaum tinning, siv tweezers, taw tes rau lub qhov ntswg pliers, thiab lwm yam.
Tsis tas li ntawd, tus nqi ntawm solder siv yuav tsum tsim nyog, thiab ib lub pob loj ntawm cov solder yuav tsum tsis txhob siv los paste lub solder sib koom. Cov txheej txheem ntawm cov hlau lead tuaj yeem pom qhov txawv ntawm qhov sib txawv ntawm cov tin saum npoo ntawm qhov sib koom ua ke, thiab cov duab hluav taws xob pom los ntawm sab ntawm qhov sib koom ua ke yog qhov tsim nyog rau kev sib koom ua ke. Thaum welding nrog ib tug handheld hluav taws xob soldering hlau, tsis txhob siv lub taub hau soldering hlau los rub lub vuam nto rov qab los yog forcefully kov thiab nias. Qhov tseeb, ntev npaum li qhov chaw sib cuag ntawm cov tin plated ib feem ntawm lub taub hau hlau thiab cov vuam nto yog nce, cov cua sov tuaj yeem hloov tau zoo ntawm lub taub hau hlau mus rau qhov chaw vuam.
Nws yuav tsum tau muab sau tseg tias tom qab tshem tawm cov hlau soldering tom qab vuam, tos kom txog thaum lub solder ntawm lub solder sib koom ua ke tag nrho solidified (4-5 vib nas this), thiab ces loosen cov tweezers los yog ob txhais tes uas kho cov khoom. Txwv tsis pub, cov hlau lead tuaj yeem tawm los yog qhov chaw ntawm cov khoom sib txuas yuav tshwm sim zoo li tofu residue. Tom qab welding, yog tias tus Tsov tus tw ntawm lub solder sib koom yog rub tawm, poob rau hauv lub rosin nrog ib tug hluav taws xob soldering hlau taub, thiab ces kho vuam kom tshem tawm nws. Yog hais tias muaj slag npoo thiab cov ces kaum, nws qhia tau hais tias lub vuam lub sij hawm ntev dhau lawm, thiab nws yog tsim nyog los tshem tawm impurities ua ntej welding.
Cov khoom ntawm lub rooj tsav xwm luam tawm yuav tsum tau muab tshem tawm thiab welded, nrog qhov sib txawv ntawm 2-4 hli nruab nrab ntawm lub cev tivthaiv thiab cov khoom siv hluav taws xob. Lawv yuav tsum tsis txhob nruj nreem txuas rau ntawm lub rooj tsavxwm nto, thiab siv lead ua transistor yuav tsum siab dua. Rau cov khoom loj, tom qab muab tso rau hauv lub rooj tsav xwm hauv lub qhov, cov hlau lead tuaj yeem khoov tau 90 degree raws li cov kev taw qhia ntawm Circuit Court tooj liab ntawv ci sawb raws li qhia hauv daim duab 6, tawm hauv qhov ntev ntawm 2 hli kom flattened thiab welded kom ruaj khov. Vuam siab input impedance pab kiag li lawm xws li integrated circuits, yog hais tias nws tsis muaj peev xwm los xyuas kom meej txhim khu kev qha kev twb kev txuas ntawm hluav taws xob soldering hlau plhaub thiab hauv av, yuav ua tau tiav los ntawm unplugging hluav taws xob soldering hlau fais plug thiab siv residual tshav kub welding.
Thaum welding Circuit Court boards, nws tseem tuaj yeem ntxig cov resistors ua ntej, weld lawv taw tes los ntawm taw tes, thiab tom qab ntawd txiav tawm qhov ntev ntawm cov txhuas siv sab cutters lossis ntsia thawv clippers. Tom qab ntawd, solder cov khoom loj dua xws li cov khoom siv hluav taws xob, thiab thaum kawg solder tshav kub-resistant thiab yooj yim siv lead ua transistors, integrated circuits, thiab lwm yam.
