Cov laug cam rau cov phiaj xwm kev ua tiav tsis tuaj yeem ua kom tsuas yog yuam, tab sis kuj tseem ua ntawm nws tus kheej hauv tsev. Txawm hais tias ib tus neeg uas tsis tau ntsib yav tas los microcircuits tuaj yeem tiv taus cov txheej txheem no.
Tsim nyog
- - tshuab luam ntawv laser;
- - soldering hlau;
- - tswvyim;
- - textolite board;
- - Cov tshuaj acetone;
- - hlau;
- - ferric chloride daws.
Cov Lus Qhia
Kauj ruam 1
Kos nws koj tus kheej lossis rub daim duab uas koj xav tsim tawm hauv Is Taws Nem. Nyob rau tib lub sijhawm, xaiv cov nplai raws li qhov loj ntawm pawg thawj coj, vim koj yuav tau txhais cov lus kos duab. Siv cov tshuab luam ntawv laser ntawm cov ntawv ci. Yuav cov ntawv luam tshwj xeeb textolite, nws yog qhov yooj yim kom pom nws hauv khw muag khoom hauv xov tooj cua hauv koj lub nroog, tom qab ntawd ntxuav nws, degrease nws nrog kua tshuaj acetone.
Kauj ruam 2
Ntsuas koj cov hlau rau qhov kub siab tshaj plaws. Tom qab ntawd, nruab ib qho teeb duab ntawm koj lub Circuit Court ntawm lub rooj tsavxwm, nco ntsoov tias nws yuav tsum tau kho, vim hais tias txwv tsis pub nws tsis zoo li koj yuav muaj peev xwm tsim ib qho txuas ntawm Circuit Court. Cov kev taw qhia ntawm kev kos duab yog qis dua, tig mus rau ntawm pawg thawj coj.
Kauj ruam 3
Khiav lub rhaub hlau dua nws ob peb zaug sib txuas, tom qab ntawd cia nws txias me ntsis. Tso dej yaug tawm cov ntawv hauv qab cov kais dej. Thaum tsuas yog toner thiab PCB nyob twj ywm rau ntawm lub rooj tsavxwm, tua cov dej thiab tawm ntawm lub rooj tswj hwm kom qhuav.
Kauj ruam 4
Mus rau txheej txheem etching. Nws tuaj yeem siv sijhawm li cas los ntawm 10-15 feeb thiab txog li ib teev, nyob ntawm qhov xwm txheej. Hauv lub thawv uas tsim nyog, dilute cov tshuaj ferric chloride nrog dej. Muab cov txiag ស្ងួត tso rau hauv nws nrog cov qauv hauv qab.
Kauj ruam 5
Thaum cov txheej txheem tiav, so lub Rooj Tswjhwm Saib nrog daim ntaub qhuav kom tshem tawm txhua yam toner seem. Saib ntawm tus qauv schematic dua, thiab tom qab ntawd laum cov qhov tsim nyog raws li cov phiaj xwm kos. Tom qab ntawv, ntxuav nws dua thiab mus rau theem tom ntej.
Kauj Ruam 6
Siv cov hlau soldering, thov ib txheej ntawm tin rau kab ntawm pawg thawj coj. Nruab txhua lwm qhov me me ntawm cov microcircuit thiab cov cam rau lawv, tsis txhob siv cov khoom siv tin ntau, kom tsis txhob muaj kev puas tsuaj rau lub Board. Tom qab ntawd, koj tuaj yeem kuaj xyuas nws cov haujlwm, tom qab paub tseeb tias qhov ntawd. Tias txhua lub ntsiab tseem tuav ruaj khov rau nws.
