Kev ceev faj rau kev siv tshuaj PCBA

Soldering yog ib qho tseem ceeb tshaj plaws ntawm PCBA pawg thawj coj saib tuam txhab hauv cov txheej txheem sib dhos ntawm cov khoom siv hluav taws xob. Yog tias tsis muaj cov txheej txheem txheej txheem txheej txheem ua tau zoo, ib qho khoom siv hluav taws xob tsim tau zoo yuav nyuaj rau ua tiav cov hom phiaj tsim. Yog li ntawd, thaum lub sij hawm vuam txheej txheem, cov haujlwm hauv qab no yuav tsum tau ua:

1. Txawm hais tias qhov weldability zoo, vuam nto yuav tsum ua kom huv.

Vim yog lub sijhawm khaws cia ntev thiab ua kom tsis huv, ua rau cov yeeb yaj kiab oxide tsis zoo, cov roj av, thiab lwm yam tuaj yeem tsim tawm ntawm qhov chaw ntawm cov khoom siv phom. Yog li, saum npoo yuav tsum tau ntxuav ua ntej vuam, txwv tsis pub nws nyuaj rau lav qhov zoo.

Precautions for soldering PCBA

2. Qhov ntsuas kub thiab lub sijhawm yuav tsum tsim nyog.

Thaum cov khoom siv sib xyaw ua ke, cov laug thiab cov hlau txuas tau ua kom sov mus rau qhov ntsuas kub kom sov, yog li cov kua nplaum yaj tau so thiab nthuav tawm ntawm cov hlau saum npoo thiab ua cov hlau sib xyaw. Yog li ntawd, txhawm rau kom ntseeg tau tias cov pob qij txha txuas tau ruaj khov, nws yuav tsum muaj qhov ntsuas qhov ntsuas kom tsim nyog. Thaum qhov kub txaus txaus, lub lauj kaub tuaj yeem ntub thiab nthuav tawm los ua cov txheej hlau. Qhov kub siab dhau rau vuam. Lub sijhawm siv lub raj muaj qhov cuam tshuam loj rau cov laug, qhov ntub dej ntawm cov khoom siv sib txuas thiab tsim cov txheej txheem sib txuas. Tswj kom raug lub sijhawm vuam yog qhov tseem ceeb rau kev ua haujlwm zoo.

3. Cov laug txuas yuav tsum muaj lub zog kho tshuab txaus.

Txhawm rau kom ntseeg tau tias cov khoom siv txuas yuav tsis poob thiab dhau los ua kev vibration lossis cuam tshuam, cov pob qij txha yuav tsum muaj lub zog ua haujlwm txaus. Txhawm rau ua kom cov pob qij txha txuas tau muaj lub zog ua haujlwm txaus, feem ntau yog txoj hauv kev khoov thiab siv cov hlau txuas ntawm cov khoom siv tuaj yeem siv tau, tab sis ntau dhau heev lawm tsis tuaj yeem sib sau ua ke, uas yog qhov yooj yim ua rau luv Circuit Court ntawm virtual soldering thiab luv Circuit Court . Cov pob qij txha thiab cov pob qij txha sib txuas.

Precautions for soldering PCBA

4 vuam yuav tsum txhim khu kev qha thiab xyuas kom muaj kev coj ua.

Txhawm rau ua kom cov pob qij txha txuas tau muaj hluav taws xob zoo, nws yog qhov tsim nyog los tiv thaiv kev dag tsis raug. Kev siv lub tshuab ziab khaub ncaws hais txog qhov tseeb tias tsis muaj cov qauv sib xyaw ntawm cov kab laug sab thiab cov kab laug sab, tab sis tsuas yog txuas rau saum npoo ntawm cov hlau yaj. Hauv vuam, yog tias tsuas yog ib feem ntawm cov hlau tau tsim thiab qhov seem tsis tau tsim, cov khoom siv sib txuas kuj tseem tuaj yeem hla tam sim no hauv lub sijhawm luv, thiab nws nyuaj rau pom qhov teeb meem ntawm qhov ntsuas. Txawm li cas los xij, raws li lub sijhawm dhau mus, cov nplaim uas tsis tsim cov hlau yuav raug oxidized, uas yuav ua rau lub sijhawm qhib thiab tawg, uas yuav ua rau muaj teeb meem khoom tsis zoo.

Hauv ntej, cov khoom sib txuas zoo yuav tsum yog: cov pob qij txha txuas tau ci thiab du; txheej txheej txheej yog ib yam thiab nyias, haum rau qhov loj ntawm lub ncoo, thiab cov qauv ntawm kev sib koom ua ke tsis meej; tus laug yog txaus thiab kis mus rau qhov zoo li daim tiab; tsis muaj kab nrib pleb, pinholes, Tsis muaj qhov dej ntws tawm.
