Vim li cas thiaj siv rosin rau soldering _Dab tsi yog kev siv rosin hauv cov txheej txheem soldering
dab tsi yog rosin
Rosin yog hais txog cov khoom uas tsis yog-volatile natural resin tau los ntawm Pine rosin los ntawm ntau txoj kev ua. Rosin yog ib qho tseem ceeb ntawm cov khoom siv raw, dav siv hauv xab npum, ntawv, xim, roj hmab thiab lwm yam lag luam.
Rosin feem ntau yog siv los ua tackifying resin nyob rau hauv kub-melt, siab-sensitive thiab hnyav-raws li adhesives kom pib tack thiab txhim kho daim ntawv cog lus zog. Rosin kuj tseem tuaj yeem txhim kho qhov ziab thiab tev lub zog ntawm dej-raws li acrylic laminating nplaum, thiab qhov kev pom zoo yog 6 feem pua ntawm tag nrho cov nyiaj monomers. Rosin yog ib qho tsis muaj zog acidic tshuaj. Yog hais tias tus nqi ntawm SBS hom universal kua nplaum los yog tshuaj tsuag kua nplaum yog loj heev, lub ntim hlau yuav corroded, thiab cov kua nplaum yuav sai sai tig xim av-dub. Txawm hais tias nws tsis cuam tshuam rau kev sib txuas ua haujlwm, qhov tsos tsis yog. Tsis ntseeg.
Rosin yog rhiab heev rau lub teeb, cua sov, thiab oxygen, tshwj xeeb tshaj yog nyob rau hauv hmoov daim ntawv, yog li nws yog ib qho yooj yim mus oxidize, yog li nws yuav tsum tau muab khaws cia tag nrho los tiv thaiv oxidation los ntawm darkening xim thiab hloov kev ua tau zoo. Thaum lub nto ntawm block rosin yog oxidized, ib tug oxide zaj duab xis yog tsim los tiv thaiv ntxiv oxidation ntawm sab hauv rosin. Cov dej noo tuaj yeem ua kom cov txheej txheem oxidation ntawm rosin, thiab acetic acid tso tawm thaum sib sib zog nqus oxidation.
Yog vim li cas siv rosin rau soldering
1. Rosin yog flux. Thaum lub taub hau ntawm cov hlau kais dej rosin, cov rosin ua lub suab "chuck" thiab emits ib tug puff ntawm cov pa luam yeeb dawb, qhia tau hais tias qhov kub yog qhov zoo thiab nws tuaj yeem soldered. Thaum siv, koj tuaj yeem siv cov rosin rau cov pob qij txha thiab cov vuam (los yog coj mus rhaub nws tom qab kub), ces kov cov hlua hlau, cov hlua, thiab cov hlua khi rau 2-3 vib nas this, thiab tshem tawm cov hlau tom qab lub solder muaj melted tusyees. Qhib lub hau ntawm cov hlau soldering kom tiav cov soldering.
2. Nrog rosin, nws yooj yim dua rau "noj cov tin", thiab cov khoom siv soldered kuj ci dua, thiab nws tsis yooj yim rau kev tsim cov khoom cuav.
3. Rosin tiv thaiv oxidation ntawm lub vuam, ua ntej tshem tawm cov oxide txheej, thiab dai tin rau hauv rosin. Muab ib co rosin rau ntawm cov pob qij txha, dai tin nyob rau hauv rosin, thiab ces solder.
4. Siv cov ntawv xuab zeb zoo los so cov oxide txheej ntawm tooj liab hlau, faus (muab) rau hauv rosin, muab lub pob loj loj (txog qhov loj ntawm lub taub hau sib tw) rau ntawm cov hlau nplaum, muab tso rau ntawm cov hlau tooj liab rau. txog ib ob los yog ob, nqa cov hlau soldering thiab coj nws tawm kab. Muab ib co rosin rau ntawm Circuit Court board. Muab ib lub pob me me rau ntawm cov hlau nplaum thiab muab tso rau ntawm lub rooj tsav xwm Circuit Court rau li ib lossis ob vib nas this. Tos ntau tshaj 30 vib nas this kom txias ib txwm, tom qab ntawd muab cov hlau tso rau, thiab tom qab ntawd so cov xyab. Siv ib lub pob me me rau ntawm cov hlau thiab solder rau li ib lossis ob vib nas this. Thib ob, tshem cov hlau soldering, tuav cov xov thiab tos kom txias txias rau ntau tshaj 3 vib nas this ua ntej tso mus.
