Cov teeb meem tshwm sim hauv Circuit Board Soldering (2)

Qhia:

Circuit board vuam yog txheej txheem tseem ceeb hauv kev tsim khoom siv hluav taws xob, ua kom muaj kev ua haujlwm zoo thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob. Txawm li cas los xij, zoo li txhua txoj kev tsim khoom, nws tsis yog tsis muaj nws cov kev cov nyom.Hauv qhov blog no, peb yuav ua kom tob tob rau hauv cov teeb meem tshwm sim feem ntau tshwm sim thaum soldering circuit boards thiab tshawb nrhiav cov kev daws teeb meem zoo los kov yeej lawv.

1. PCB board luv Circuit Court:

Ib qho teeb meem feem ntau hauv Circuit Board soldering yog luv luv Circuit Court. Lub voj voog luv luv tshwm sim thaum tam sim no siv txoj hauv kev tsis xav tau vim muaj qhov tsis sib xws ntawm ob lub ntsiab lus hauv Circuit Court. Qhov no tuaj yeem tshwm sim los ntawm ntau yam, xws li cov txuas txuas txuas, cov khoom siv hluav taws xob tsis zoo, lossis cov teeb meem tsim.

tshuaj:

Txhawm rau kom tsis txhob muaj luv luv Circuit Court, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo xyuas thiab sim lub rooj tsavxwm tom qab cov txheej txheem soldering. Ua raws li kev tshuaj xyuas qhov muag pom (AOI) thev naus laus zis tuaj yeem pab txheeb xyuas cov teeb meem luv luv. Tsis tas li ntawd, siv cov cuab yeej soldering precision, xws li cov hlau soldering nrog kev tswj qhov kub thiab txias, tuaj yeem pab tiv thaiv cov solder ntau dhau los ntawm kev tsim cov kev sib txuas uas tsis xav tau.

2. Tsaus thiab grainy hu:

Tsaus thiab grainy hu rau ntawm PCB nto yuav qhia tau tias muaj kev sib txuas tsis zoo. Qhov teeb meem no feem ntau yog tshwm sim los ntawm kev hloov hluav taws xob tsis txaus thaum lub sij hawm ua cov txheej txheem soldering, ua rau tsis tiav wetting ntawm solder joint.

tshuaj:

Yuav kom ua tiav qhov ntub dej kom zoo thiab tiv thaiv qhov tsaus ntuj, kev sib cuag grainy, vuam tsis yuav tsum tau ua kom zoo. Xyuas kom tseeb tias lub taub hau hlau yog huv si, tinned, thiab ntawm qhov kub thiab txias. Tsis tas li ntawd, siv flux thaum lub sij hawm soldering tuaj yeem txhim kho cov dej ntws thiab txhim kho kev sib koom ua ke. Flux pab tshem tawm cov oxides thiab cov kab mob ntawm cov hlau, txhawb kev ntub dej zoo dua thiab muaj zog dua cov pob qij txha.

3. PCB solder pob qij txha tig golden daj:

Thaum cov pob qij txha ntawm lub PCB nto tig daj daj, nws qhia tau hais tias muaj teeb meem xws li tsis raug solder alloy muaj pes tsawg leeg lossis cov cuab yeej siv tsis raug. Qhov teeb meem no tuaj yeem cuam tshuam qhov kev ncaj ncees thiab kev ntseeg siab ntawm lub rooj tsav xwm Circuit Court.

tshuaj:

Kev siv cov khoom siv hluav taws xob raug yog qhov tseem ceeb los xyuas kom meej lub neej ntev ntawm koj lub rooj tsav xwm Circuit Court. Ib txwm ua raws li kev lag luam tus qauv solder alloy cov khoom sib xyaw thiab tsis txhob siv cov khoom siv tsis zoo los yog tsis muaj ntawv pov thawj. Tsis tas li ntawd, kev tswj xyuas qhov kub thiab txias kom zoo thiab siv cov txheej txheem soldering kom zoo, suav nrog preheating PCB thiab siv cov khoom siv zoo, tuaj yeem pab ua kom zoo zoo golden solder pob qij txha.

4. Kev cuam tshuam ntawm ib puag ncig ntawm Circuit Court board tsis xws luag:

Qhov chaw nyob rau hauv uas Circuit Court boards yog soldered kuj tseem cuam tshuam rau qhov zoo ntawm cov khoom kawg. Cov yam ntxwv xws li cov av noo, qhov kub thiab txias, thiab cov pa paug tuaj yeem ua rau muaj ntau yam tsis xws luag hauv Circuit Board.

tshuaj:

Txhawm rau txo qhov kev cuam tshuam ib puag ncig ntawm Circuit Court board tsis xws luag, nws yog ib qho tseem ceeb los tsim kom muaj kev tswj hwm kev tsim khoom. Kev puas tsuaj los ntawm hluav taws xob zoo li qub tuaj yeem tiv thaiv los ntawm kev siv ESD (electrostatic paug) ceev faj, xws li siv ESD chaw ua haujlwm nyab xeeb thiab hnav cov iav tiv thaiv. Tsis tas li ntawd, kev tswj xyuas qhov kub thiab av noo zoo hauv thaj chaw tsim khoom pab tiv thaiv cov teeb meem xws li vuam tsis xws luag thiab cov khoom degradation.

Hauv kev xaus:

Circuit board soldering yog cov txheej txheem nyuaj uas yuav tsum tau ua kom raug thiab ua tib zoo saib kom meej.Los ntawm kev daws cov teeb meem uas tshwm sim thaum lub sijhawm txheej txheem no, cov tuam ntxhab tuaj yeem ua kom cov khoom siv hluav taws xob zoo, txhim khu kev qha. Ua raws li cov kev daws teeb meem uas tau tham hauv blog no, xws li cov txheej txheem kev tshuaj xyuas zoo, kev ua kom zoo dua qub, thiab kev tswj hwm ib puag ncig, tuaj yeem txhim kho tag nrho qhov zoo ntawm Circuit Court board soldering.
