Lub tswv yim rau smoothing thiab ntxuav qhov saum npoo ntawm cov hlau solder pob qij txha
1. Scrape ua ntej thiab tom qab ntawd solder: Yog tias muaj roj stains lossis xeb ntawm cov hlau lead ntawm cov khoom yuav tsum tau soldered, nws tsis yooj yim rau noj tin. Txawm hais tias lub solder yog NW nyuam qhuav "pas tseg", qhov tshwm sim yuav yog cuav soldering. Scrape huv si ua ntej welding. Muab cov pins tso rau hauv rosin thiab rub cov tin-muaj cov hlau nplaum rov qab thiab rov qab rau ntawm cov pins kom txog rau thaum cov txheej nyias nyias coated ntawm cov pins.
Lub solderability ntawm cov khoom siv hluav taws xob feem ntau yog qhov zoo heev. Kev tuav vuam tsis tas yuav tsum tau tin dripping kev kho mob (qhov yuav tsum tau ua ntej yog siv cov hlau nplaum nrog flux). Yog hais tias cov khoom raug khaws cia tsis raug thiab ua rau oxidation los yog av ntawm cov khoom siv pins, tin dripping yuav tsum tau kho. .
2. Ua kom paub qhov kub thiab txias. Yog hais tias qhov kub tsis txaus, lub solder yuav muaj fluidity tsis zoo thiab yuav yooj yim solidify. Yog tias qhov kub thiab txias heev, nws yuav drip tau yooj yim. Cov pob qij txha tsis tuaj yeem tuav lub solder.
(1) Yog tias qhov kub thiab txias yog qhov tsim nyog, siv cov hlau soldering nrog lub zog sib xws raws li qhov loj ntawm cov khoom.
(2) Master lub sijhawm cua sov. Lub taub hau ntawm lub taub hau yog solder los nias lub vuam taw tes. Cov khoom yuav tsum tau welded yog rhuab. Thaum lub solder cia li ntws los ntawm lub soldering hlau taub mus rau cov khoom yuav tsum tau soldered. Qhia tias lub sijhawm cua sov tau tas sijhawm. Thaum lub sij hawm no, sai sai tshem tawm cov soldering hlau taub. Qhov no yoojyim ib qho ci, du solder chaw. Lub solder sib koom ua ke tsis tuaj yeem khaws cia los ntawm kev tshem tawm cov taub hau hlau. Nws txhais tau tias lub sijhawm cua sov yog luv. Qhov kub tsis txaus. Los yog cov pob qij txha yog qias neeg heev. Lub solder ntws downward ua ntej lub soldering hlau taub raug tshem tawm. Lub sijhawm cua sov yog ntev heev thiab qhov kub thiab txias siab dhau lawm.
3. Siv tus nqi tsim nyog ntawm solder: Tus nqi ntawm solder dipped nyob rau hauv raws li qhov loj ntawm solder sib koom yog txaus los npog cov khoom yuav tsum tau soldered. Tsim ib qho ci thiab du solder sib koom ua ke. Yog hais tias lub solder tsis txaus nyob rau hauv ib lub sij hawm, nws muaj peev xwm yuav replenished. Txawm li cas los xij, lub taub hau hlau yuav tsum tau muab tshem tawm tom qab lub solder yav dhau los tau yaj ua ke. Qee tus neeg tuaj yeem sib sau ua ke zoo li nqos ua lub zes thaum vuam. Yog li ntawd, ntau lub solder tau soldered tab sis nws tsis muaj zog.
4. Tuav nws ruaj khov thiab tsis co: Cov khoom siv soldering yuav tsum tau tuav ruaj khov thiab clamped kom nruj, tshwj xeeb tshaj yog thaum lub sij hawm solidification theem ntawm solder, nws yuav tsum tsis txhob co. Kev co thaum lub sij hawm solidification tuaj yeem yooj yim ua rau vuam tsis tseeb. Cov pob qij txha zoo li taum paj. So koj lub dab teg ntawm kev txhawb nqa rau kev ruaj ntseg. Ua kom ncaj thaum zaum lossis sawv.
5. Siv cov tshuaj txhuam hniav tsawg dua: Nws yog ib qho acidic additive. Cov tshuaj nplaum yuav tsum tau muab ntxuav kom huv tom qab soldering los tiv thaiv corrosion ntawm Circuit Court. Txhawm rau tshem tawm cov pob qij txha, siv qhov me me no thiab sim tsis txhob siv cov tshuaj txhuam hniav.
Rosin yog ib qho zoo dua thaum siv rosin-free solder strips. Muab cov hlau nplaum rau hauv cov hlau nplaum, ces coj mus rhaub rau ntawm rosin thiab solder sai sai. Los yog siv 95% cawv thiab rosin los ua ib qho flux thiab tsuas yog muab tso rau ntawm nws thaum vuam.
Tsis tas li ntawd, cov tshuaj kuj tuaj yeem txhuam ntawm cov pob qij txha huv huv thiab cov ntawv luam tawm hauv Circuit Court boards kom lawv ci ntsa iab li qub.
