Ib lub microcircuit yog cov khoom siv hluav taws xob me me tso rau ntawm lub semiconductor siv lead ua. Microcircuits yog tsim nrog lossis tsis muaj qhov sib cais tsis sib haum thaum microcircuits siv nyob rau hauv kev tsim cov microassemblies. Txhawm rau txhim kho lossis rhuav tshem cov microcircuit, muaj ob peb txoj cai.

Hloov microcircuits: yuav ua li cas kho

Nws yog qhov tsim nyog

  • - hluav taws xob soldering hlau, 25 watts;
  • - hlau cam POS-61;
  • - kev nqus rau ham.

Cov Lus Qhia

Kauj ruam 1

Yuav cov ntawv ci hlau nrog ib daim yuag, ntse taub thiab lub zog siab tshaj plaws ntawm 25 watts los ntawm lub khw muag khoom xov tooj cua. Qhov ntxeev ntawm soldering hlau yuav tsum tau muab hauv av, raws li ntau ICs rhiab heev hluav taws xob zoo li qub. Ua raws li cov cai no, txwv tsis pub cov microcircuit yuav raug puas thaum lub sijhawm teeb tsa.

Kauj ruam 2

Yuav cov roj hmab hluav taws xob yaj qis los ntawm lub khw muag khoom xov tooj cua, piv txwv li POS-61. Nws twb muaj flux-rosin tsim nyog rau soldering. Cov tub luam yuav xav tau txhawm rau nce lub microcircuit.

Kauj ruam 3

Yuav cov ham nqus ntawm khw muag khoom xov tooj cua. Qhov yooj yim solder nqus yog lub tshuab nqus tsev twj tso kua mis. Xav kom muag teeb ib pliag thaum cheem tawm lub microcircuit.

Kauj ruam 4

Disassemble lub faulty microcircuit. Txhawm rau ua qhov no, muab cov khaub ncaws nqus piston rau txoj haujlwm ua haujlwm thiab ua kom sov cov hlau yaj yeeb nrog. Qhuav yaj ntawm txhais ceg ntawm microcircuit. Nqa cov xuas tes xuas mus rau nws thiab nias lub pob tshuaj xuas tawm. Nyob rau hauv cov ntaub ntawv no, lub molten solder yog nqus rau hauv sab hauv kev nqus. Nyob rau hauv txoj kev no, ntxuav txhua txhais ceg ntawm lub microcircuit qub los ntawm ham thiab tshem nws los ntawm pawg thawj coj.

Kauj ruam 5

Yog tias lub microcircuit pheej pheej yig, tom qab ntawd nruab nws rau ntawm lub rooj tsavxwm nyob rau hauv txoj kev ib txwm. Ua tib zoo hle cov ceg ntawm qhov tshiab microcircuit. Tso cov microcircuit tshiab nyob rau hauv qhov chaw ntawm tus qub rau hauv pawg thawj coj. Thov siv qee cov tshuaj txhuam rau qhov cub hlau soldering. Muag tag nrho cov ceg ntawm lub microcircuit sai sai thiab meej nyob rau hauv lem.

Kauj ruam 6

Yog tias lub microcircuit yuav kim, yuav ib lub vaj huam sib luag rau nws loj hauv cov xov tooj cua. Teeb lub vaj huam sib luag sawv cev ntawm lub microcircuit qub thiab tso cov microcircuit tshiab rau hauv nws. Yog hais tias lub microcircuit hloov tawm mus ua qhov tsis ua haujlwm, koj tuaj yeem hloov nws hauv khw muag khoom xov tooj cua rau qhov sib xws lossis xa rov qab cov nyiaj siv. Cov tsev muag khoom hauv xov tooj cua tsis lees txais cov xov tooj cua hauv xov tooj cua coj los sib pauv.
