Cov tooj liab txheej ntawm luam tawm hauv Circuit Court board yog qhov tseem ceeb ntawm txhua qhov kev tsim hluav taws xob, lwm txheej tsuas yog txhawb lossis tiv thaiv Circuit Court, lossis ua kom yooj yim dua cov txheej txheem sib dhos. Rau Ib tus kws tsim qauv PCB, lub hom phiaj tseem ceeb tsuas yog kom tau txais kev sib txuas los ntawm taw tes A mus rau taw tes B nrog qee qhov teeb meem ntau li ntau tau.

Cov txheej tooj liab ntawm cov ntawv luam tawm Circuit Board yog qhov ua kom pom tseeb ntawm txhua qhov kev tsim hluav taws xob, lwm txheej tsuas yog txhawb lossis tiv thaiv Circuit Court, lossis ua kom yooj yim dua cov txheej txheem sib dhos. Rau Ib tus kws tsim qauv PCB, lub hom phiaj tseem ceeb tsuas yog kom tau txais kev sib txuas los ntawm taw tes A mus rau taw tes B nrog qee qhov teeb meem ntau li ntau tau.

Txawm li cas los xij, nrog sijhawm thiab kev paub, PCB tus tsim qauv tsom mus rau:

kev piav qhia

artistic

Kev siv qhov chaw

Zuag qhia tag nrho

Tus nqi qis

Kev muaj nyob los ntawm tus nqi nrawm thiab zoo

Homemade PCB

Feem ntau tshwm sim vim lub sijhawm hloov pauv

Kev tshaj lij PCB

Siv ntau txoj hauv kev txhawm rau txhim kho nws txoj haujlwm thiab ua siab ntev

L Ua kom zoo dua ntawm cov txheej txheem etching thiab cov cuab yeej zoo dua thiab kev tshaj lij

Vim tias muaj kev cuam tshuam loj heev ntawm kev tshaj lij, qhov sib txawv ntawm cov kws tshaj lij thiab cov kws tshaj lij tau dhau los ua ntau dua li kev ua siab ntev

Qhov sib txawv ntawm qhov pheej yig thiab vaj tsev zoo kuj tau pom meej dua

PCB etching cov kauj ruam:

1. Sib npaug thov tus kws yees duab rau lub phaj tooj liab

Tus kws kho qhov muag tau nkag siab rau lub teeb ci ultraviolet thiab tawv tom qab raug. Tus kws kho qhov muag tom qab npog nrog qhov tsis zoo ntawm cov duab ntawm txheej tooj liab ntawm phaj.

2. Lub teeb ci ultraviolet muaj zog siv los nthuav tawm hauv qab npog ntawm lub rooj tsav xwm hauv Circuit Court

Lub teeb ci ultraviolet muaj zog yuav ua rau cov cheeb tsam uas yuav tsum nyob ruaj khov rau daim hlau tooj liab. Cov thev naus laus zis zoo ib yam li uas tau siv los ua cov khoom siv hluav taws xob nrog kaum tawm nanometers hauv qhov loj me, yog li nws muaj peev xwm ua tau zoo ntawm cov yam ntxwv zoo.

3. Raus tag nrho lub rooj tsav xwm hauv Circuit Court hauv kev daws kom tshem cov tawv tawv photoresist

4. Siv tooj liab lwm yam los tshem cov tooj liab uas tsis xav tau

Ib qho kev sib tw nthuav hauv cov kauj ruam yog qhov xav tau los ua anisotropic etching. Thaum cov tooj liab tau kos rau hauv qab, ntug ntawm cov tooj liab tiv thaiv raug nthuav tawm thiab tsis muaj kev tiv thaiv. Qhov ua kom zoo dua qub, qhov me me ntawm kev tiv thaiv txheej sab saum toj mus rau txheej txheej sab.

5. Laum qhov hauv PCB

Los ntawm plating los ntawm qhov rau mounting qhov, cov qhov no tuaj yeem siv rau txhua qhov kev siv sib txawv hauv PCB. Thaum cov qhov no ua tiav, tooj liab tau tso rau sab hauv lub qhov phab ntsa uas siv cov tooj liab uas tsis muaj hluav taws xob los ua ib qho kev txuas hluav taws xob hla lub rooj tsavxwm.

Hom kev tsim khoom thiab qauv tsim ntawm PCB tuaj yeem tsis quav ntsej lossis tsis tuaj yeem tsis quav ntsej. Txawm hais tias tus tsim qauv tsis xav tau ntau xyoo ntawm PCB kev tsim khoom thiab kev sib sau ua ke, kev nkag siab zoo ntawm yuav ua li cas cov no yuav ua rau koj nkag siab zoo txog yuav ua li cas thiab vim li cas PCB tsim tau zoo.
