5 kauj ruam kom raug solder nrog ib tug soldering hlau
Vuam thev naus laus zis, raws li kev txawj ntse, ua lub luag haujlwm tseem ceeb hauv kev tsim hluav taws xob. Thaum manually soldering nrog ib tug hluav taws xob soldering hlau, nws yog ib qhov tsim nyog yuav tau paub tej yam kev txawj ntse, uas yog muaj nyob rau hauv tag nrho cov txheej txheem soldering ntawm 10 lub ntsiab lus tseem ceeb - "ib tug scraping, ob plating, peb xeem, plaub soldering, thiab tsib checking".
1. Ib qho kos
Ntxuav lub ntsej muag ntawm cov khoom siv hlau los ntawm khawb tawm cov oxide txheej, cov roj stains lossis cov xim rwb thaiv tsev ntawm qhov chaw vuam nrog ib rab riam me me, seem hlau saw hniav, thiab lwm yam. cov hlau tshiab raug nthuav tawm. Ua ntej soldering, cov ntawv luam tawm hauv tsev kuj yuav tsum tau ua tib zoo polished nrog cov ntawv xuab zeb zoo los yog dej xuab zeb ntawm sab npog nrog tooj liab ntawv nyiaj. 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 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 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 ntawm qhov chaw, nws tuaj yeem muab tshem tawm nrog cov roj hmab ntxhib raws li qhia hauv daim duab 3 (c). 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 transistor pins thiab leads yuav nyuaj rau tin tom qab scraping tawm txheej. Txawm hais tias siv "scraping" hom dab tsi, yuav tsum tau them nyiaj mloog mus tas li tig cov pins ntawm cov khoom kom paub meej tias tag nrho cov voj voog ntawm cov pins huv si.
2. Thib ob plating
Tin thaj tsam yuav tsum tau welded. Lub soldering qhov chaw ntawm scraped tivthaiv pins, xov hlau, thiab lwm yam yuav tsum tam sim ntawd coated nrog ib tug tsim nyog tus nqi ntawm solder thiab ib tug nyias txheej ntawm tin yuav tsum tau plated nrog ib tug hluav taws xob soldering hlau los tiv thaiv nto oxidation thiab txhim kho cov solderability ntawm cov khoom. Lub plated solder txheej yuav tsum nyias thiab sib xws, yog li tus nqi ntawm solder ntawm lub taub hau hlau yuav tsum tsis txhob ntau dhau txhua zaus. Rau cov khoom siv xws li siv lead ua diodes thiab transistors uas nkag siab rau cov cua sov, lawv yuav tsum tau clamped ntawm lub hauv paus ntawm cov hlau lead pins nrog tweezers los yog taw tes pliers raws li qhia hauv daim duab 4 (b) los pab kom cov cua sov dissipate, thiab ces tin plated. Tin txheej ntawm cov khoom siv hluav taws xob yog cov txheej txheem tseem ceeb hauv kev siv tshuab vuam los tiv thaiv kev phom sij xws li virtual soldering thiab cuav soldering, thiab yuav tsum tsis txhob maj maj.
3. Peb qhov kev xeem
Kev ntsuam xyuas yog kev tshuaj xyuas cov khoom uas tau tinned, saib seb puas muaj kev puas tsuaj, deformation, los yog soldering (luv luv Circuit Court) ntawm cov khoom nyob rau hauv kub kub ntawm ib tug hluav taws xob soldering hlau. Rau cov khoom xws li capacitors, transistors, thiab kev sib xyaw ua ke, yuav tsum siv lub tshuab multimeter los xyuas lawv qhov zoo rau kev ntseeg tau. Cov khoom uas pom tias tsis muaj kev ntseeg siab lossis puas tsuaj yuav tsum tsis txhob rov siv dua.
4. Plaub vuam
Vuam yog cov txheej txheem ntawm soldering tsim nyog Cheebtsam mus rau ib tug luam Circuit Court board los yog xaiv qhov chaw raws li xav tau. Thaum vuam, nws yog ib qho tseem ceeb los tswj qhov kub thiab txias lub sij hawm vuam ntawm cov hlau soldering. Yog tias qhov kub thiab txias qis dhau los yog lub sijhawm vuam luv dhau, lub ntsej muag lub ntsej muag yuav muaj lub ntsej muag zoo li tus Tsov tus tw zoo li daim duab 5 (a), thiab qhov saum npoo yuav tsis du, txawm tias zoo li tofu residue raws li pom hauv daim duab. 5 (b). Nws yog tau hais tias vim tsis tiav evaporation ntawm lub solder flux, muaj ib tug tej yam npaum li cas ntawm solder flux tshuav ntawm lub solder thiab hlau. Tom qab txias, lub solder flux (rosin) yuav lo rau saum npoo hlau thiab tuaj yeem rub tawm nrog me ntsis quab yuam, uas yog hu ua cuav soldering.
