Vuam cov txheej txheem ntawm hluav taws xob soldering hlau
chais plaub
Scraping txhais tau hais tias ua ntej vuam, qhov saum npoo ntawm cov welded hlau yuav tsum tau muab ntxuav raws li qhia hauv daim duab 3. Ib rab riam me me, cov hlau sawb, thiab lwm yam tuaj yeem siv los txhuam tawm (los yog siv cov ntawv xuab zeb zoo los yog cov roj hmab ntxhib los so) oxide txheej, roj stains, los yog rwb thaiv tsev pleev xim rau ntawm vuam nto kom txog rau thaum ib tug tshiab hlau nto raug. Ua ntej welding nws tus kheej-ua luam ntawv Circuit Court boards, nws tseem yuav tsum tau ua tib zoo polish ib sab ntawm cov ntawv ci nrog cov xuab zeb zoo los yog dej xuab zeb. Scraping yog ib kauj ruam tseem ceeb los xyuas kom meej vuam zoo, tab sis nws yog feem ntau overlooked los ntawm beginners. Yog hais tias lub scraping tsis ua kom zoo, nws yuav ua rau tsis zoo tin plating thiab vuam. Nws yuav tsum raug sau tseg tias qee cov khoom siv lead ua twb tau nyiaj plated, kub plated, lossis tinned. Tsuav yog tsis muaj oxidation lossis tev, tsis tas yuav khawb lawv dua. Yog tias muaj av nyob rau saum npoo, siv cov roj hmab tuab los tshem tawm. Kev xaiv cov roj hmab tuab yog qhov zoo tshaj plaws thaum siv cov roj hmab loj rau kev kos duab. Qee cov kub plated crystal transistor pins thiab leads yuav pom tias nws nyuaj rau tin tom qab scraping tawm txheej. Tsis muaj teeb meem dab tsi ntawm "scraping" yog siv, nws yog ib qho tseem ceeb kom tsis tu ncua tig cov pins tivthaiv thiab xyuas kom meej tias tag nrho cov ncig ntawm cov pins huv si.
plating
Plating yog txheej txheem ntawm tinning qhov chaw yuav tsum tau welded. Tom qab scraping, lub soldering qhov chaw xws li cov pins thiab hlau taub hau ntawm lub Cheebtsam yuav tsum tau coated tam sim ntawd nrog ib tug tsim nyog tus nqi ntawm soldering flux, thiab ib tug nyias tin txheej yuav tsum tau coated nrog ib tug hluav taws xob soldering hlau los tiv thaiv nto oxidation thiab txhim kho cov solderability. cov khoom. Cov txheej txheej uas yuav tsum tau plated yuav tsum nyias thiab sib xws, yog li tus nqi ntawm cov khoom siv ntawm lub taub hau hlau yuav tsum tsis txhob ntau dhau txhua zaus. Rau cov khoom xws li siv lead ua diodes thiab transistor uas ntshai ntawm scalding, nws yog ib qhov tsim nyog yuav tau siv cov tweezers los yog taw tes pliers rau clamp lub hauv paus ntawm cov hlau lead pin ua ntej los pab dissipate tshav kub, thiab ces pib nrog tin plating kev kho mob. Tin txheej ntawm cov khoom yog cov txheej txheem tseem ceeb hauv kev siv thev naus laus zis los tiv thaiv cov kev phom sij zais xws li cov khoom cuav thiab cov khoom cuav, thiab yuav tsum tsis txhob muaj kev saib xyuas.
ntsuas
Kev ntsuam xyuas yog kev tshuaj xyuas cov khoom siv tin coated kom pom tias muaj kev puas tsuaj, deformation, sib tshooj vuam (luv luv), thiab lwm yam. Rau cov khoom xws li capacitors, transistors, integrated circuits, thiab lwm yam, ib tug multimeter kuj yuav tsum tau siv los xyuas seb lawv cov khoom puas zoo. Cov khoom uas pom tias tsis muaj kev ntseeg siab lossis puas yuav tsum tsis txhob rov qab siv dua.
vuam
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.
