Tsav Tus Sab Nraud Sab Nraud:

Lub npe hu ua Single Side Board, uas yog, ntawm PCB feem ntau, tag nrho cov khoom nyob rau hauv ib sab, thiab cov xov hlau muaj tag nrho cov sab nraud. Vim tias cov xov hlau tsuas tshwm ntawm ib sab xwb, peb hu ua hom PCB hu ua Ib Pawg Neeg Sab Nraud. Vim tias Pawg Neeg Ib Sab ntawm tus qauv tsim muaj ntau txoj cai txwv (vim tias tsuas muaj ib sab xwb, qhov thaiv tsis tau hla thiab yuav tsum nyob ib ncig ntawm txoj kev), yog li tam sim no tsis tau siv, feem ntau siv nyob rau hauv cov ntawv cog lus thaum ntxov;

Tsuas yog Sab Daj Kab Taws Xwb rau lub ntsiab network luam tawm, uas yog, luam tawm ntawm qhov chaw xaim ntawm tus neeg ua haujlwm tsis kam, tom qab lub sijhawm thiab tom qab ntawd tiv thaiv kab kos rau ntawm lub cim, thiab thaum kawg los xuas xuas ua qhov chaw ua tiav qhov thiab qhov zoo. Tsis tas li ntawd, ib qho tsawg ntawm ntau ntau hom khoom, kev siv photoresist tsim ib tug qauv ntawm photography.

Raws li daim duab peb pom tau qee yam, tab sis daim duab tsis yog meej meej, yog li cov duab tsuas yog siv los ua ib qho kev siv, cov nram qab no peb yuav tsum saib cov txheej txheem tsim yog qhov nws zoo li.

1, npaj qhov:

Thaum pib ntawm PCB qhov kev teeb tsa, peb yuav tsum xub ua tiav cov schematic tsim, tau txais qhov tseeb schematic, uas yog lub hauv paus ntawm Pawg Neeg Sab Phab Xwb ua tus tsim. Los ntawm cov tswv yim peb tuaj yeem tau txais ib qhov txuas mus rau cov khoom ntawm txhua qhov khoom siv lub network, ntxiv rau, raws li cov khoom siv tsis tau, peb tuaj yeem pom cov ntaub ntawv tivthaiv thiab kev tsim ntawm txhua feem ntawm pob. Tsis tas li ntawd, qhov kev xav tau ntawm cov khoom ua ke nrog lub rooj tsavxwm thiab thav duab thiab qhov chaw ntawm lub installation, qhov chaw ua haujlwm tsis zoo.

2, lub lag luam tshwj xeeb qhov:

Ua ntej txhua yam yuav tsum tau import tag nrho cov pob khoom thiab cov rooj sib tham ntawm network rau hauv lub hauv paus ntawm kev tsim cov ntawv PCB. Thaum txoj kev ntshuam tuaj, tej zaum yuav tau muab cov khoom ntim tawm tuaj. Thov ua raws li cov lus yuam kev rau rectify qhov yuam kev.

3, kev ruaj ntseg muaj feem xyuam nrog cov khoom siv:

Koj xav kom muaj kev ruaj ntseg, xws li LED, cov khawm, lub lawj, LCD, infrared transmitter thiab lwm yam khoom siv. Tshem cov khoom siv no rau qhov chaw sib txuas, thiab xaiv lub ntsuas phoo hauv cov khoom kom txhob siv tsis raws cai.

4, qhov kev teeb tsa dav dav:

Lub hom phiaj ntawm qhov kev teeb tsa dav dav yog los txiav txim xyuas qhov chaw ntawm ntau lub modules, hauv PCB tsim, feem ntau yog:

Ntxiv nrog rau cov khoom siv uas yuav tsum tau muab ntsa rau ntawm qhov chaw, tag nrho cov khoom ua ke muab tso rau ntawm ib sab ntawm lub plooj-txuas, feem ntau hauv qab;
