Lub reflow soldering chaw tsim tshuaj paus Shenzhen Chengyuan kev lag luam tau pom cov nram qab no teeb meem nyob rau hauv reflow soldering rau lub sij hawm ntev.Cov hauv qab no yog qee qhov teeb meem uas tshwm sim, nrog rau cov lus qhia rau kev saib xyuas thiab kev tiv thaiv:
1. Qhov saum npoo ntawm cov pob qij txha zoo li frosted, crystallized los yog ntxhib.
Kev Kho: Qhov kev sib koom ua ke no tuaj yeem kho tau los ntawm kev rov ua kom sov thiab cia nws txias tsis muaj kev cuam tshuam.
Kev Tiv Thaiv: Kev ruaj ntseg cov pob qij txha tiv thaiv kom tsis txhob muaj teeb meem
2. Tsis tiav melting ntawm lub solder, feem ntau yog yus muaj los ntawm ib tug ntxhib los mos nto.Solder adhesion tsis zoo nyob rau hauv rooj plaub no, thiab cov kab nrib pleb tuaj yeem loj hlob hauv kev sib koom ua ke thaum lub sijhawm.
Kev Kho: Nws tuaj yeem kho tau yooj yim los ntawm kev rov ua kom lub qhov sib koom ua ke nrog cov hlau kub kom txog thaum lub vuam ntws.Ntau tshaj solder feem ntau tuaj yeem kos tawm nrog lub hau ntawm cov hlau.
Kev Tiv Thaiv: Ib qho zoo preheated soldering hlau nrog lub zog txaus yuav pab tiv thaiv qhov no.
3. Lub solder sib koom yog overheated.Lub solder tseem tsis tau ntws zoo, thiab cov residue los ntawm burnt flux ua rau qhov no tshwm sim.
Kho: Overheated solder pob qij txha feem ntau tuaj yeem kho tom qab ntxuav.Tshem tawm cov hluav taws kub hnyiab los ntawm kev ua tib zoo txhuam nrog lub hau ntawm rab riam los yog txhuam hniav.
Kev Tiv Thaiv: Ib qho huv, zoo kub soldering hlau, kev npaj kom zoo thiab ntxuav cov pob qij txha yuav pab tiv thaiv cov pob qij txha overheated.
4. Cov pob qij txha tag nrho pom cov cim ntawm cov ntaub qhwv tsis txaus.Lub solder ntub cov hlau lead zoo, tab sis nws tsis tsim ib daim ntawv cog lus zoo nrog cov ntaub qhwv.Qhov no tuaj yeem yog vim lub rooj tsavxwm qias neeg, lossis tsis ua kom sov lub ncoo thiab pins.
Kev Kho: Qhov mob no feem ntau tuaj yeem kho tau los ntawm kev tso lub hau ntawm cov hlau kub rau hauv qab ntawm qhov sib koom ua ke kom txog rau thaum lub solder ntws los npog lub ncoo.
Kev Tiv Thaiv: Kev ntxuav lub rooj tsavxwm thiab txawm tias cua sov cov ntaub qhwv thiab cov pins tuaj yeem tiv thaiv qhov teeb meem no.
5. Lub solder nyob rau hauv qhov sib koom ua ke tsis ntub tus pin ntawm tag nrho thiab tsuas yog ib feem ntub lub ncoo.Nyob rau hauv rooj plaub no, tsis muaj cua sov rau cov pins, thiab cov solder tsis muaj sij hawm txaus ntws.
Kev Kho: Qhov kev sib koom ua ke no tuaj yeem kho tau los ntawm kev rov ua kom sov thiab siv ntau dua solder.Xyuas kom tseeb tias qhov kawg ntawm cov hlau kub kov tus pin thiab ncoo.
Kev Tiv Thaiv: Txawm tias cua sov cov pins thiab cov ntaub qhwv tuaj yeem tiv thaiv qhov teeb meem no.
6. (Nto Mount) Peb muaj peb tus pins ntawm ib qho chaw mount qhov chaw uas lub solder tsis ntws mus rau hauv ncoo.Qhov no yog tshwm sim los ntawm cua sov tus pin, tsis yog lub ncoo.
Kho: Kho yooj yim los ntawm cua sov lub ncoo nrog lub taub hau solder, ces siv cov solder kom txog thaum nws ntws thiab melts nrog solder ntawm tus pin.
7. Solder starved solder pob qij txha yooj yim tsis muaj solder txaus rau solder.Hom kev sib koom ua ke no yog qhov ua rau muaj teeb meem.
Txhim kho: Rov ua kom sov cov leeg sib koom ua ke thiab ntxiv cov hlua txuas ntxiv kom ua kom muaj kev sib cuag zoo.
8. Ntau dhau solder
Txhim kho: Feem ntau koj tuaj yeem kos tawm qee qhov ntau dhau nrog lub hau ntawm cov hlau kub.Nyob rau hauv qhov xwm txheej hnyav, ib lub tshuab nqus tsev los yog ib co solder wick kuj tseem pab tau.
9. Yog hais tias cov hlau lead yog ntev dhau lawm, muaj kev pheej hmoo ntawm qhov luv luv Circuit Court.Ob lub pob qij txha ntawm sab laug yog qhov txaus ntshai rau kov.Tab sis tus ntawm sab xis kuj txaus ntshai heev.
Kho: Txiav tag nrho cov ua rau saum cov pob qij txha.
10. Ob leeg solder pob qij txha ntawm sab laug yaj ua ke, tsim kom muaj kev sib txuas ntawm ob.
Txhim kho: Qee lub sij hawm dhau cov solder tuaj yeem rub tawm los ntawm kev rub lub hau ntawm cov hlau kub ntawm ob lub pob qij txha.Yog tias muaj solder ntau dhau, ib lub tshuab nqus tsev los yog cov nplaum nplaum tuaj yeem pab kos tawm qhov dhau.
Kev Tiv Thaiv: Weld bridging feem ntau tshwm sim ntawm cov pob qij txha nrog cov welds ntau dhau.Tsuas yog siv tus nqi ntawm cov solder kom ua tau zoo sib koom ua ke.
11. Cov ntaub qhwv tshem tawm ntawm lub rooj tsavxwm.Qhov no tshwm sim feem ntau thaum sim desolder ib feem ntawm lub rooj tsavxwm, tejzaum nws yog vim nplaum tsis ua hauj lwm.
Qhov no yog tshwj xeeb tshaj yog muaj nyob rau ntawm cov laug cam nrog nyias tooj liab txheej los yog tsis plated los ntawm qhov.
Tej zaum nws yuav tsis zoo nkauj, tab sis feem ntau nws tuaj yeem kho tau.Qhov kev txhim kho yooj yim tshaj plaws yog muab cov hmoov txhuas hla cov tooj liab uas tseem txuas nrog thiab solder nws raws li qhia rau sab laug.Yog tias koj muaj lub npog ntsej muag ntawm koj lub rooj tsavxwm, nws yuav tsum tau ua tib zoo khawb kom pom cov tooj liab liab.
12. Stray solder spatter.Cov solders no tuav ntawm lub rooj tsavxwm nkaus xwb los ntawm cov nplaum nplaum nplaum.Yog hais tias lawv los xoob, lawv tuaj yeem yooj yim luv luv ntawm lub rooj tsavxwm.
Kho: Tshem tawm yooj yim nrog lub hau ntawm rab riam lossis tweezers.
Yog hais tias cov teeb meem saum toj no tshwm sim, tsis txhob ntshai.Siv nws yooj yim.Feem ntau cov teeb meem tuaj yeem kho nrog kev ua siab ntev.Yog hais tias lub solder tsis ntws raws li koj xav tau:
(1) Nres thiab cia qhov sib koom ua ke txias.
(2) Ntxuav thiab txhuam koj cov hlau soldering.
(3) Ntxuav txhua qhov kub hnyiab ntawm qhov sib koom ua ke.
(4) Tom qab ntawd rov ua dua.
