PCB kev npaj muaj ntau theem:

1 Npaj cov khoos phis tawj PC siv EAGLE, Sprint-Layout, Proteus 8 Professional lossis lwm yam haujlwm tau txais

Luam Screen Xim Sib cais & Zaj duab xis luam ntawv rau PCB

3.PCB ib leeg/ob npaug txiav qhov loj thiab ntxuav

4. Xim rau nws nrog lub vijtsam luam ntawv ntxaij

5. Nws tuaj yeem tshaj 65 degrees rau 25 feeb

6. Muab daim ntawv pob tshab tso rau hauv PCB qhuav

7.UW irradiation rau 1 feeb

8 Tom qab ntawd tso ferric (III) chloride FeCl3

Kauj Ruam 1: Npaj lub khoos phis tawj PC siv EAGLE, Sprint-Layout,

Yuav ua li cas thiaj ua tau zoo PCB

Sprint-layout ua haujlwm tsuas yog vim nws zoo nkauj

Nws yooj yim mus nrhiav lwm cov haujlwm

Kauj Ruam 2: Luam cov ntawv luam tawm cov xim sib cais xim & AMP; Zaj duab xis luam tawm ntawm PCB

Ib daim ntawv hloov pauv PCB tau luam tawm hauv qhov chaw luam ntawv ze tshaj plaws – Kuv txiav nws thiab tso nws mus rau lwm sab vaj huam sib luag

Kev kho yooj yim nrog cov hlau txuas

Kauj Ruam 3: PCB ib leeg/ob npaug txiav qhov loj thiab huv

Kauj Ruam 4: Xim nrog lub vijtsam luam ntawv ntxaij

PCB pawg thawj coj saib nrog ob tog tooj liab daim kab xev ntxuav cawv

Kauj Ruam 5: Nws tuaj yeem tshaj 65 degrees rau 25 feeb

Koj tuaj yeem siv qhov ntsuas kub rau txhua txoj hlua

Lub microwave tsis ua haujlwm

Kauj Ruam 6: UV teeb rau 1 feeb

Ntxuav nrog sodium hydroxide

Lus ceeb toom: Sodium hydroxide ua teeb meem rau kev noj qab haus huv

Kauj Ruam 7: Tom qab ntawd tso Iro N (III) Chloride FeCl
