Yuav ua li cas solder ib tug hlau rau hlau nyob rau hauv lub tsev

Ib tug ntau yam ntawm txoj kev thiab hom kev kawm ntawm soldering yeej ib txwm siv los sau tej hluav taws xob Circuit Court los ua ib tug tiav lawm Circuit Court board nrog cov xov tooj cua hais rau tag nrho cov paub meej nyob khov kho nyob rau hauv qhov chaw. Soldering raug tsis tsuas ntau yam nyob ntawm tej, cables, tab sis kuj cov qhov muag teeb, resistors, transistors, diodes, kev circuits, lub lag luam, cov nyees khawm, choj circuits, etc. Far tsis txhua leej txhua tus paub yuav ua li cas solder lub hlau rau cov hlau, txawm tias qhov no muaj peev xwm tej zaum yog heev tsim nyog.

Pike koj yuav pab tau txawm nyob rau hauv tsev yog tias koj muaj cov differential voltage rau lub network ntawd hlawv hlau mus rau hauv koj nyiam mloog xov tooj cua, los yog koj tau txiav txim siab los sau lawv tus kheej ob txhais tes hwj chim mus rau ib tug neeg sab nrauv rau koj cov suab paj nruag yog louder.

Qhov kev xaiv ntawm solder thiab lwm yam kev seev

Ua ntej cov tswv yim ncaj qha mus rau lub soldering, nws yog tsim nyog los xaiv ib tug soldering hlau thiab txhua tsav txhua yam uas koj xav tau rau kev ua hauj lwm.

Thawj xaiv ib tug soldering hlau, lawv txawv nyob rau hauv hwj chim. Yog li ntawd, nws yuav tsum tau muab sau tseg hais tias nws yog tsim nyog los solder. Yog hais tias qhov no tej ntsiab, ntshai ntawm muaj zog overheating, los yog nti, lub zoo hwj chim ntawm tus soldering hlau yog 5-20 watts. Yuav kom solder ib tug hlau rau hlau los yog davhlau ya nyob twg, haum soldering hlau nrog ib lub hwj chim ntawm 40-50 watts. Rau tebchaw ntawm hlau ntsiab uas muaj ib tug tuab ntawm 3 hli, nws yog tsim nyog los xaiv ib tug soldering hlau nrog ib lub hwj chim ntawm 50 watts. Tsis tas li ntawd mus ua hauj lwm nrog ib tug soldering hlau koj yuav tau npaj:

- Tes Solder;

- ntev ciaj tais;

- ciaj;

- rosin solder flux los yog acid.

Yuav ua li cas los npaj rau soldering

Ua ntej soldering ua hauj lwm plev yog tshem ntawm hmoov quav los ntawm nws cov stripping cov ntaub ntawv. Ces soldering yog kev cob cog rua rau lub network, yog rhuab thiab dipped nyob rau hauv rosin.

Yog hais tias koj twb yeej tsis ua hauj lwm nrog ib tug soldering hlau thiab tsis paub yuav ua li cas solder lub hlau rau cov hlau, koj yuav tsum xyaum. Ua li no, siv sij hawm ib daim ruaj hlau tsis rwb thaiv tsev, thiab faib mus rau hauv 12 kwv yees li sib npaug zos qhov chaw los ntawm 2.5 cm txhua. Siv ciaj tais, soldering hlau, solder thiab flux, sim mus sau rau daim ntawm lub thawv muaj rau sab. Nws yuav ua tau zoo kev kawm kev qhia soldering. Thaum tus tsim yog npaj txhij, cia nws txias thiab saib yuav ua li cas los tuav ceev ceev mus rau tag nrho cov kev sib txuas. Yog hais tias ib yam dab tsi tau poob tawm - resolder.

Ua ntej ua hauj lwm rau tag nrho cov qhov chaw nyob qhov twg soldering yog ua, nws yog tsim nyog los tin.

Tseem ceeb soldering cai

Solder hlau soldering hlau yuav tsum tau ua raws li tej yam kev cai ntawm lub chaw ua hauj lwm yuav tsum tau snug thiab ruaj ntseg raws li ib tug tshwm sim. Brazing solder yog yuav tsum tau, feem ntau uas nquag siv yog lub PIC 40, lub PIC 50, PIC-61. Xeem kev vam meej thiab yog feem ntau siv nyob rau hauv qhov. Yuav kom ua tau soldering, nws yog tsim nyog los sov li lub qhov chaw, uas yog solderable rau qhov kub thiab txias uas cov tshuaj lo yog tau yaj, thiab cov nyob ntawm tej tsis overheated.

Tag nrho cov ua hauj lwm ntawm soldering nyob ntawm tej muaj successive theem:

- Nyob ntawm tej yog npaj rau soldering. Lub oxide zaj duab xis yuav tsum tau muab tshem tawm los so solder acid los yog rosin.

- Pre-rhuab soldering hlau yog coj tuaj rau lub solder, nws yuav siv sij hawm ib tug heev me ntsis kom tsis txhob ib tug loj influx nyob rau hauv qhov chaw soldering.

- Thov solder nyob ntawm tej rau cov hlau thiab mus rau lub point ntawm kev sib cuag yog coj soldering raws nraim lub sij hawm uas koj xav tau rau TES SOLDER tseem nyob rau hauv lub qhov chaw ntawm lub hlws ris nyob ntawm tej.

Koj tsis tas yuav ib tug soldering hlau ntau heev ncua nyob ze ntawm lub nyob ntawm tej. Tsuas yog ib tug ob peb lub vib nas this rau solder nyob ntawm tej kev sib khi. Tom qab txoj kev lwj siab yog muab tshem tawm los ntawm cov tshuaj lo pob qij txha, lub solder hardens. Yuav kom lub hlws ris tsis tau solder thiab nws muab tawm zoo huv si, nyob ntawm tej xav tau los tuav tseem kom txog thaum tiav solidification ntawm cov tshuaj lo. Yog hais tias lub site muaj pov thawj los ua ib tug overabundance ntawm soldering flux - nws yuav tsum tau muab tshem tawm. Nws yog tsim nyog los muab cov soldering yog tsis oxidized lub sij hawm.

yuav pab tau yim pab

Ua ntej koj yuav xyaum rau tus kheej kev, yuav ua li cas solder lub hlau rau cov hlau, muab ib tug ob peb tswv yim uas koj yuav xav tau.

Thaum lub sij hawm soldering yog tsis tsim nyog los siv ib tug ntau ntawm lo, nws NW nyuam qhuav txaus solder yuav tau mus rau hauv lub feeb kis ntawm cov khoom thiab cov nyiaj nyob ntawm tej. Qhov no yuav ua tau txaus rau intermolecular sis rog pib ua.

Yuav kom tshem tawm cov tshaj lo, koj muaj peev xwm siv lub braided ntaub thaiv npog, coj los ntawm tej cable. Tsis tas li ntawd, siv ib tug soldering hlau, uas yog, nyob rau txoj kev lwj siab furrow mus rau hauv uas tshaj solder tau txais thaum kov tej chaw adhesions.

Ntau dhau lawm solder tej zaum yuav ua ib tug hu rau kaw.

Yog hais tias koj noj ntau dhau me ntsis solder nyob rau ntxeev ntawm ib tug soldering hlau - koj yuav tsis tau solder dab tsi.

Yog hais tias lub soldering hlau yuav tsum muaj ib tug ntau ntawm soot, los yog flux - solder yuav substandard. Cov tib yuav tshwm sim yog hais tias tus soldering hlau yog tsis rhuab mus rau yuav tsum tau kub.

Tsis txhob hnov qab hais tias nws yog tsim nyog los tinker nrog ib tug zoo duab los yog nyob rau hauv ib tug zoo ventilated cheeb tsam.

Tam sim no koj paub yuav ua li cas solder ib tug hlau rau hlau kom raug.
