Yav dhau los kuv tau ua PCB's nrog cov ntawv ua kom muaj zog tiv taus los yog nrog cov cim hloov pauv seno. Ua PCB's nrog UV qhov ncauj qhov ntswg thiab tsim tshuaj lom neeg tsis txaus siab ib yam. Ob txoj hauv kev yog anoyng heev thiab siv sijhawm. Yog li kuv tuaj nrog cov txheej txheem tom qab los hloov qhov tsim qauv mus rau txheej tooj liab ntawm PCB pawg thawj coj nrog yooj yim thiab hauv lub sijhawm luv luv.

Hauv cov lus qhia luv luv no kuv yuav qhia koj tias kuv tau ua dab tsi los ua PCB zoo.

Kauj Ruam 1: Yam Koj Xav Tau

Koj xav tau:

• Kev tsim qauv luam tawm ntawm koj lub xov tooj cua
• nkag mus lossis nyob rau tom qab ntawm lub tshuab luam ntawv laser
• daim ntawv nplaum
• Acetone
• Ib lub polibloc lossis lwm yam los ntxuav sab tooj liab ntawm koj li PCB
• tus neeg sawv cev kos npe zoo li FE3CL
• Ib lub laminator

Kauj Ruam 2: Thawj Yam Ua Ntej…

Asuming tias koj tau tsim cov phiaj xwm npaj rau kev xa mus rau PCB, ua ntej ua qee qhov kev xeem ntawm daim ntawv ib txwm los tshuaj xyuas qhov ntsuas.

Tom qab ntawd nqa daim ntawv nplaum thiab rub tag nrho cov ntawv nplaum. Tam sim no koj muaj daim ntawv nrog rau ntawm ib sab txheej tsis lo (yog cov ntawv nplaum tau nyob) thiab qee cov ntawv nplaum xoob. Pov tseg cov ntawv nplaum, koj tsis xav tau lawv. Qhov no tsis lo (Kuv xav tias silicon) txheej ntawm daim ntawv nplaum uas tsis muaj nplaum yog sab uas koj yuav tsum luam koj tus qauv rau (pic 2). Tsis txhob hnov qab luam koj daim iav tsom iav!

Xyuas kom tseeb tias txheej tooj liab tau ntxuav nrog Polibloc lossis cov ntawv txhuam zoo heev, tom qab ntawd ntxuav nws nrog acetone (daim duab 3 thiab 4)

Kauj ruam 3: Hloov chaw

Nthuav cov ntawv nrog cov ntawv luam tawm sab saud sab saud ntawm lub rooj thiab tso lub rooj tsavxwm nrog rau sab tooj liab sab saud, qhia meej ntawm cov qauv tsim hluav taws xob (daim duab 1).

CEEV FAJ! Txawm hais tias lub tshuab luam ntawv tsis poob ntawm daim ntawv los ntawm nws tus kheej, nws tsis kho! Koj tuaj yeem rub nws tawm yooj yim yog tias koj tsis ceev faj. Yog li koj yuav tsum tau ceev faj kom tsis txhob hloov pauv PCB hauv kev cuam tshuam nrog daim ntawv txwv tsis pub koj cov ntawv yuav ua tsis ncaj

Tam sim no, thaum nias koj lub PCB, ua tib zoo khoov ib sab ntawm daim ntawv thiab kho nws nrog daim kab xev nplaum rau sab nraum qab ntawm PCB (daim duab 2).

Kauj Ruam 4: Kho Toner ntawm PCB

Hauv cov kauj ruam tom ntej koj yuav tsum ua shure tsis hloov daim ntawv ntawm PCB. Kev hloov daim ntawv nrog rau lub siab ntau tuaj yeem ua rau tus txiv tsev toner puas.

Tam sim no coj PCB nrog daim ntawv atached thiab khiav nws hla lub tshuab ua kom sov ua ntej (daim duab 1 thiab 2). Txhawm rau ua kom tooj liab txheej kub txaus, rov ua qhov no ob peb zaug tab sis ceev faj: tom qab txhua qhov kev ua haujlwm PCB tau kub dua thiab kub dua!. Tom qab 4 khiav hla lub laminator rub kom zoo ib lub ces kaum ntawm daim ntawv kom pom tias cov tshuaj toner patern tau kho kom raug, thiab yog tias tsis yog txhua tus toner tau hloov pauv, khiav nws lub tshuab laminator dua kom txog thaum tag nrho cov toner raug xa mus (daim duab 3 thiab 4). Hauv theem no daim ntawv nrog tus qauv tsim tau ua ncaj ncees rau PCB thiab tsis hloov pauv yooj yim. Tab sis txhua lub sijhawm ceev faj!

Ib qho qhab nia cim cim tseg tom qab ntawm daim ntawv yog ua tau.

Txheeb xyuas txhua txoj hauv kev thiab sau rau hauv ib sab laug aways nrog tus cim ruaj khov (txiav lub ntsiab lus nrog rab riam ntse kom ua tus taw tes nyias). Tsuas yog qhov chaw uas kuv yuav tsum tau ua uas yog nyob ntawm lub qhov. Txhua yam ntxiv tau zoo!

Tam sim no lub rooj tsavxwm tau npaj rau kev kos.

Kauj ruam 5: Tom qab Etching

Tom qab kos nws hauv koj tus neeg saib xyuas cov ntawv, tshem tawm lub toner nrog cov ntawv xuab zeb zoo lossis Polibloc los ua kom pom cov tooj liab pom thiab txheeb xyuas qhov tsis sib xws (daim duab 1 thiab 2)

Kauj Ruam 6: Qhov tshwm sim

Qhov kawg tshwm sim yog PCB zoo heev npaj rau kev khawb thiab khawb. Tsis muaj qhov ua yuam kev thiab txawm tias txoj kab nruab nrab ntawm ob qhov chaw tau zoo tag nrho (koj tuaj yeem pom peb ntawm lawv ntawm daim duab).

Zoo siab hloov!
