Nyob rau hauv lawv txoj haujlwm, xov tooj cua electronics feem ntau tsim muaj ntau yam kev ua voj voos rau ntau yam khoom siv. Rau cov xov tooj cua novic amateurs, kev tsim cov phiaj xwm zoo li yog qhov ua rau lub sijhawm tsis txaus ntseeg thiab cuam tshuam, txawm li cas los xij, ua raws li cov lus qhia ntxiv, txhua tus pib tshiab tuaj yeem hloov qhov kev xav no.
Tsim nyog
- - tshuab luam ntawv laser;
- - hlau;
- - ntawv ci xim;
- - PCB pawg thawj coj saib;
- - ferric chloride;
- - hluav taws xob Cheebtsam.
Cov Lus Qhia
Kauj ruam 1
Thaum pib ntawm kev ua haujlwm, nrhiav hauv Is Taws Nem lossis teeb tsa koj tus kheej daim duab ntawm lub voj voos luam tawm. Tom qab ntawd, siv lub tshuab luam ntawv laser thiab luam koj daim duab kos rau ntawm ntawv ci (zoo dua ntawm Lomond, vim nws tau tsim nws tus kheej ntawm cov xov tooj cua amateurs). Tom qab ntawd, npaj cov ntawv txiag rau textolite los kos cov qauv ntawm nws: ntxuav nws nrog ntaub nplaum zoo thiab degrease nrog acetone.
Kauj ruam 2
Tom qab hle, muab cov ntawv luam tawm coj los ntxiv rau hauv pawg thawj tswj hwm textolite nrog tus qauv qis thiab txhim kho nws. Tom qab ntawd, hlau daim ntawv nrog hlau preheated mus rau qhov siab tshaj plaws, tsis pub nws txav thiab hloov nws qhov chaw qub. Cia lub rooj tsavxwm txias rau ob peb feeb, tom qab ntawd muab nws tso rau hauv qhov dej ntws, maj mam muab cov ntawv ci tawm kom tsuas yog cov ntawv ci thiab toner nyob twj ywm. Tso rau ntawm lub Rooj Tswjhwm Saib kom qhuav.
Kauj ruam 3
Thaum lub rooj tsavxwm ua kom qhuav, npaj ib cov tshuaj tov ntawm ferric chloride: dilute cov hmoov ntawm cov tshuaj no hauv dej. Cov kauj ruam tom ntej yog los tso koj cov txiag ntoo qhuav hauv qhov kev daws teeb meem, ua qauv qis, kom nws ntab rau saum npoo (koj tuaj yeem txuas ib daig ua npuas dej rau sab nraub qaum nrog nws daim kab xev). Tus txheej txheem no hu ua pickling thiab tuaj yeem siv sijhawm txhua qhov los ntawm 10 feeb txog 1 teev.
Kauj ruam 4
Tom qab cov txheej txheem etching tiav, qhuav lub rooj tsavxwm thiab ntxuav nws ntawm toner. Tho qhov raws li koj daim duab schematic, ntxuav daim txiag dua. Tom qab ntawd, xoob lub rooj tsavxwm - siv ib txheej tiv thaiv kom tsis txhob xoom xaim ntawm koj lub xaim hluav taws xob uas siv cov hlau yaj hlau.
Kauj ruam 5
Cov kauj ruam kawg, muab cov khoom siv hluav taws xob tsim nyog (capacitors, resistors, microcircuits, thiab lwm yam) rau ntawm koj lub rooj tsavxwm thiab ua tib zoo muab lawv tso rau hauv qhov xav tau ua dhau los siv me me ntawm tin. Tsis tas li, tsis txhob siv lub hlau ntaug mus rau lub rooj tsavxwm kom ntev heev kom tsis txhob rhuav tshem cov khoom siv hluav taws xob thiab cov ciav hlau ntawm lub rooj tsav xwm.
