Tus Pcb Board cov txheej txheem yog qhov tseem ceeb ntawm cov khoom lag luam hluav taws xob tsim kev lag luam thiab qhov txuas tseem ceeb hauv kev ua kom muaj kev ua tau zoo thiab ruaj khov hluav taws xob. Cov txheej txheem ntau lawm ntawm PCB pawg thawj coj yog qhov yooj yim heev, koom nrog ntau qhov sib txuas thiab cov kauj ruam.
1, tsim qauv PCB
Ua ntej pib ua tus pcb board, nws yog qhov tsim nyog los tsim PCB board ua ntej. Tus qauv tsim ntawm PCB Board hais txog cov txheej txheem ntawm kev hloov pauv hluav taws xob rau hauv kev ua si tiag tiag. Cov txheej txheem tsim yuav tsum tau siv cov software tsim software, thiab cov tsim qauv yuav tsum tau ua haujlwm xws li Pcb Board cov layout, Circuit Court Txuas, thiab kev tso chaw raws li cov duab hluav taws xob. Thaum tsim qauv, nws tseem yuav tsum tau xav txog qhov loj thiab cov duab ntawm PCB Board kom ntseeg tau tias nws tuaj yeem ua rau hauv lub hom phiaj ntaus ntawv.
2, PCB board manufacturing
PCB Board tsim cov neeg raug hais txog cov txheej txheem ntawm luam tawm cov qauv tsim qauv pcb board txawv mus rau lub tooj liab phaj. Cov txheej txheem ntawm pawg thawj coj ua suav nrog cov kauj ruam hauv qab no:
(1) Npaj cov phiaj tooj liab. Firstly, nws yog ib qho tsim nyog los xaiv ib lub phaj tooj liab uas haum, ntxuav nws kom huv si, thiab txhuam nws kom ua tiav. Tom qab, nws yog ib qho tsim nyog los siv cov yeeb yaj kiab qhuav rau ntawm lub phaj tooj liab.
(2) phaj duab ua. Tso daim duab tsim qauv ntawm PCB pawg thawj coj ntawm lub tooj liab phaj thiab siv ultraviolet yees duab los tiv thaiv tus photoresist rau ultraviolet teeb. Tom qab tus photoresist yog nthuav tawm, nws tau tsim los ua lub thawv photoresist ntawm lub rooj tsavxwm.
(3) etching. Etch tus tsim tooj tooj liab phaj hauv tshuab etching. Thaum lub sij hawm etching txheej txheem, photoresist tau txhim kho kev tsim ntawm tooj liab xov tooj thiab muab kev tiv thaiv etching, khaws cov xov tooj liab etch. Thaum kawg, tshem tawm cov photoresist, tawm hauv qab qhov yuav tsum tooj liab xov hlau thiab cov ntsiab lus drilling.
3, Drilling ntawm PCB Board
Txhawm rau pab txhawb kev teeb tsa cov hluav taws xob hluav taws xob, cov qauv tsim feem feem ntau qhia cov chaw uas yuav tsum tau ua. Txij ntawm no, nws yog ib qho tsim nyog los siv lub rig rig rau kev tho. Ua ntej drilling, nws yog ib qho tsim nyog los txiav txim siab qhov drilling qhov tob thiab txoj kab uas hla, thiab tom qab ntawd kho lub tshuab tooj liab ntawm lub tshuab drilling rau drilling. Tom qab drilling tau ua tiav, chamfering thiab tu kev puas tsuaj tseem xav tau kom ntseeg tau ib qho du ncig lub qhov thiab tsis txhob muaj kev tiv thaiv sib xyaw ua ke.
4, Txheej ntawm PCB Board
Thov ib zaj duab xis nyias ntawm PCB Board tuaj yeem nce nws cov corrosion tsis kam thiab rwb thaiv tsev ua haujlwm. Ua ntej siv cov pcb pcb, nws yog qhov tsim nyog los tshem tawm zaj duab xis. Cov txheej txheem ntawm kev thov zaj duab xis yog raws li hauv qab no:
(1) Xaiv kev xaiv. Xaiv cov khoom ua yeeb yaj kiab uas tsim nyog raws li cov kev xav tau thiab thov cov xwm txheej ntawm PCB Board. Membrane cov ntaub ntawv feem ntau suav nrog polyvinylidene fluoride (PVDF), Polyurethane (PI), thiab lwm yam.
(2) siv cov khoom siv ua ntej. Txhaj cov khoom ua yeeb yaj kiab rau hauv lub xeev ua kua thiab tom qab ntawd hle nws mus rau tus thawj coj PCB.
(3) Kom qhuav. Muab cov PCB PCB rau cov khoom siv zaj duab xis rau hauv qhov cub kom ziab.
(4) Laum qhov. Qhib lub qhov ncauj qhov ntswg rau txiav thiab txheej ntawm pcb board.
