Cov khoom siv hluav taws xob yog cov ntaub ntawv tseem ceeb rau kev ua cov chips, qee cov khoom sib txawv thiab sib txawv, xav tau kev cia tshwj xeeb los xyuas kom meej tias tsis muaj teeb meem, kub thiab av noo rhiab Cheebtsam yog ib qho ntawm lawv.Kub thiab av noo rhiab Cheebtsam tswj kev khaws cia hauv cov txheej txheem ua haujlwm tseem ceeb dua, yuav cuam tshuam ncaj qha rau kev ua haujlwm zoo ntawm PCBA.Ua kom ntseeg tau tias smt SMD ua tiav thaum siv cov khoom kub thiab cov av noo kom raug, tiv thaiv cov khoom los ntawm ib puag ncig noo noo, av noo thiab kev siv cov khoom ntim khoom tiv thaiv zoo li qub, cov ntsiab lus hauv qab no tuaj yeem tswj tau zoo, kom tsis txhob muaj kev tswj xyuas cov ntaub ntawv tsis raug. thiab cuam tshuam rau qhov zoo.
Peb txoj kev tswj hwm hauv qab no los ntawm kev txheeb xyuas cov hauv qab no
Kev tswj ib puag ncig
Txheej txheem tswj
Component cia lub voj voog
I. Kev tswj hwm ib puag ncig (kho cov av noo-rhiab cov khoom ntawm ib puag ncig)
General PCBA ua Hoobkas yuav tsim ib qho kev tswj ntawm qhov kub thiab txias thiab cov av noo rhiab heev, lub rhiav ib puag ncig kub yuav tsum tau tswj ntawm 18 ℃ -28 ℃.Nyob rau hauv cia, qhov kub yuav tsum tau tswj ntawm 18 ℃ -28 ℃ thiab txheeb ze av noo tsawg tshaj li 10%.Yuav kom tswj tau qhov kub thiab av noo ib puag ncig nyob rau hauv qhov chaw kaw ntawm lub Hoobkas, qhov chaw yuav tsum tsis txhob qhib los yog qhib rau ntau tshaj 5 feeb.
Cov neeg ua haujlwm cov ntaub ntawv txhua 4 teev los xyuas lub thawv ntim dej noo thiab av noo, thiab nws qhov kub thiab av noo tus nqi sau npe hauv "kub thiab av noo tswj lub rooj";Yog hais tias qhov kub thiab av noo ntau tshaj qhov teev tseg, tam sim ntawd ceeb toom rau cov neeg ua hauj lwm kom txhim kho, thaum siv cov kev kho kom tsim nyog (xws li muab cov desiccant, kho chav tsev kub los yog tshem tawm cov khoom nyob rau hauv lub faulty noo noo-pov thawj lub thawv, mus rau hauv lub tsim nyog noo noo- proof box)
II.Kev tswj cov txheej txheem (humidity-sensitive components storage method)
1. Txhawm rau tiv thaiv kev puas tsuaj rau cov khoom siv hluav taws xob zoo li qub, hauv kev rhuav tshem cov av noo-rhiab cov khoom nqus ntim, tus neeg teb xov tooj yuav tsum xub hnav cov hnab looj tes zoo li qub, lub nplhaib tes zoo li qub, thiab tom qab ntawd qhib lub tshuab nqus tsev ntim ntawm lub tshuab nqus tsev uas muaj kev tiv thaiv zoo li qub. hluav taws xob.Xyuas seb qhov kub thiab av noo daim npav hloov pauv ntawm cov khoom ua tau raws li qhov yuav tsum tau ua, thiab cov khoom ua tau raws li qhov yuav tsum tau muaj tuaj yeem sau npe.
2. Yog tias koj tau txais cov av noo-sensitive Cheebtsam, ua thawj zaug kom paub meej tias cov khoom puas tsim nyog.
3. Tshawb xyuas tias lub hnab ntim dej noo yuav tsum tau nrog cov desiccant, txheeb ze humidity card, thiab lwm yam.
4. Humidity rhiab heev Cheebtsam (IC) tom qab unpacking lub nqus tsev vacuum, rov qab mus rau lub solder ua ntej lub sij hawm raug nyob rau hauv cov huab cua yuav tsum tsis txhob tshaj cov av noo rhiab Cheebtsam qib thiab lub neej, yuav tsum nruj me ntsis raws li cov qauv ntawm lub PCBA ua cov nroj tsuag. ua haujlwm.
5. kev khaws cov khoom tsis tau qhib yuav tsum tau muab khaws cia raws li qhov yuav tsum tau ua, rau cov khoom qhib yuav tsum tau muab ci thiab muab tso rau hauv cov hnab ntim dej noo thiab lub tshuab nqus tsev kaw ua ntej lawv tuaj yeem khaws cia.
6. Rau cov khoom tsis tsim nyog, muab rau cov neeg ua haujlwm tswj xyuas kom zoo rov qab mus rau lub tsev rau khoom.
III.Lub sijhawm khaws cia ntawm cov khoom
Tsis pub ntau tshaj 2 xyoos txij li hnub tsim khoom los ntawm cov chaw tsim khoom lag luam rau cov khoom lag luam.
Tom qab kev yuav khoom, tag nrho cov neeg siv khoom siv lub sijhawm khoom muag feem ntau tsis pub dhau 1 xyoos: Yog tias qhov chaw ib puag ncig yog cov chaw tsim khoom lag luam, tom qab kev yuav khoom ntawm cov khoom sib dhos rau saum npoo, yuav tsum siv li ntawm 3 lub hlis, thiab cov av noo tsim nyog - yuav tsum tau noj. nyob rau hauv qhov chaw cia thiab cov khoom ntim khoom pov thawj ntsuas.
