10.Kev paub txog

Kev paub txog dej noo

Cov khoom siv hluav taws xob feem ntau yuav tsum tau khaws cia hauv qhov chaw qhuav. Raws li kev txheeb cais, ntau tshaj li ib feem peb ntawm lub ntiaj teb kev tsim khoom lag luam

Cov khoom siv tsis raug thiab cov dej tsis zoo raug kaw txhua xyoo. Rau kev lag luam hluav taws xob, kev phom sij ntawm cov dej noo tau dhau los ua ib qho tseem ceeb

yam hauv kev tswj cov khoom zoo.

(1) Integrated Circuit Court: Kev puas tsuaj ntawm cov dej noo rau kev lag luam semiconductor feem ntau manifests cov dej noo uas yog infiltrated thiab txuas nrog

sab hauv IC. Dej vapor yog tsim nyob rau hauv cov txheej txheem cua sov ntawm cov txheej txheem SMT, thiab lub siab generated ua rau tawg ntawm IC resin pob.

thiab oxidation ntawm cov hlau hauv IC ntaus ntawv. , ua rau cov khoom tsis ua haujlwm. Tsis tas li ntawd, thaum lub cuab yeej yog soldered thaum lub sij hawm PCB board, lub solder

kev sib koom ua ke siab kuj yuav ua rau kev sib koom ua ke.

(2) Cov khoom siv lead ua kua: Cov iav substrate, polarizer thiab lim lens ntawm cov kua siv lead ua kua xws li kua siv lead ua kua zaub tau ntxuav thiab ziab hauv

cov txheej txheem ntau lawm, tab sis lawv tseem yuav raug cuam tshuam los ntawm cov dej noo tom qab txias, txo cov txiaj ntsig ntawm cov khoom. . Yog li ntawd, nws yog khaws cia rau hauv ib qho chaw qhuav

tom qab ntxuav thiab ziab.

(3) Lwm yam khoom siv hluav taws xob: capacitors, ceramic li, connectors, hloov qhov chaw, solder, PCB, siv lead ua, silicon wafer, quartz oscillator, SMT nplaum,

electrode cov ntaub nplaum, hluav taws xob muab tshuaj txhuam, cov khoom siv ci ntsa iab, thiab lwm yam. Yuav raug rau cov dej noo.

(4) Cov khoom siv hluav taws xob hauv lub sijhawm ua haujlwm: cov khoom ua tiav ib nrab ntawm lub pob rau cov txheej txheem tom ntej; ua ntej thiab tom qab PCB pob thiab nruab nrab ntawm

lub hwj chim; IC, BGA, PCB, thiab lwm yam tom qab unpacking tab sis tsis siv; tos cov tin furnace Soldering li; cov cuab yeej uas tau muab ci los ua

ua kom sov; cov khoom uas tsis tau ntim khoom yuav raug ya raws.

(5) Lub tshuab hluav taws xob ua tiav tseem yuav raug cov dej noo thaum lub sijhawm khaws cia thiab khaws cia. Yog tias lub sijhawm khaws cia ntev ntev hauv qhov chaw kub kub,

nws yuav ua rau tsis ua hauj lwm, thiab CPU ntawm daim npav computer yuav oxidize tus ntiv tes kub thiab ua rau kev sib cuag Brown rau malfunction.

Kev tsim cov khoom siv hluav taws xob hauv kev lag luam thiab qhov chaw cia khoom ntawm cov khoom yuav tsum qis dua 40% RH. Qee hom kuj xav tau cov av qis.

Kev khaws cia ntawm ntau cov ntaub ntawv noo noo ib txwm ua rau mob taub hau rau txhua qhov chaw ntawm lub neej. Lub soldering ntawm hluav taws xob Cheebtsam thiab Circuit Court boards yog

Nws muaj feem xyuam rau cov khoom cuav tom qab yoj soldering, uas ua rau muaj kev nce ntxiv ntawm cov khoom tsis raug. Txawm hais tias nws tuaj yeem txhim kho tom qab ci thiab

dehumidification, kev ua tau zoo ntawm cov khoom yog deteriorated tom qab ci, uas ncaj qha cuam tshuam rau cov khoom. Kev ua tau zoo, thiab kev siv cov thawv dej tsis zoo

tuaj yeem daws cov teeb meem saum toj no zoo.
