Kev piav qhia ntxaws ntawm Cov Ntsiab Lus Desoldering Thiab Cov Ntsiab Lus Ua Haujlwm ntawm PCBA ua
Oct 20, 2022
Hauv kev ua PCBA, tom qab kuaj xyuas qhov zoo ntawm cov khoom siv hluav taws xob, nws yog ib qho tsim nyog yuav tsum tau disassemble thiab solder cov khoom siv hluav taws xob tsis zoo. Yog tias koj xav tshem tawm cov khoom siv hluav taws xob tsis raug cai yam tsis muaj kev puas tsuaj rau lwm yam khoom thiab PCB pawg thawj coj saib, koj yuav tsum paub txog kev ua PCBA thiab disassembly thiab soldering kev txawj ntse. Tom ntej no, tus editor yuav qhia rau koj txog cov ntsiab lus desoldering thiab cov ntsiab lus ua haujlwm ntawm PCBA ua.
1. Cov hauv paus ntsiab lus ntawm desoldering:
Nco ntsoov txheeb xyuas cov yam ntxwv ntawm cov pob qij txha qub ua ntej desoldering, thiab tsis txhob ua nws maj mam.
(1) Tsis txhob rhuav tshem cov khoom, cov xov hlau thiab cov khoom nyob ib puag ncig kom raug tshem tawm;
(2) Tsis txhob ua kom cov ntaub qhwv thiab cov xov hlau luam tawm ntawm lub pcb thaum lub sij hawm desoldering;
(3) Rau cov khoom siv hluav taws xob uas tau txiav txim siab puas lawm, cov pins tuaj yeem raug txiav ua ntej thiab tom qab ntawd tshem tawm, uas tuaj yeem txo qhov kev puas tsuaj;
(4) Sim zam kom tsis txhob txav txoj haujlwm ntawm lwm cov khoom qub, thiab yog tias tsim nyog, rov kho lawv.
2. Cov ntsiab lus tseem ceeb ntawm kev ua haujlwm desoldering:
(1) nruj me ntsis tswj cov cua kub thiab lub sij hawm kom tsis txhob kub kub puas rau lwm yam Cheebtsam. Feem ntau, lub sij hawm thiab qhov kub thiab txias ntawm desoldering yog ntev tshaj li ntawm soldering.
(2) Tsis txhob siv lub zog ntau dhau thaum desoldering. Lub pob lub zog ntawm cov khoom nyob rau hauv qhov kub thiab txias yuav txo qis, thiab ntau dhau rub, sib tw, thiab sib tw yuav ua rau cov khoom puas thiab cov ntaub qhwv.
(3) Ncua lub solder ntawm qhov chaw desoldering. Koj tuaj yeem siv lub tshuab nqus tsev nqus los nqus cov solder thiab tshem tawm cov khoom ncaj qha, txo lub sij hawm desoldering thiab muaj peev xwm ua kom puas lub pcb.
Qhov no yog lub hauv paus ntsiab lus ntawm desoldering thiab cov ntsiab lus tseem ceeb ntawm kev ua haujlwm hauv PCBA ua. Kuv vam tias yuav muab kev pab rau koj.
