Ib qho hneev taw lossis cov qauv av yog kev teeb tsa cov pawm (hauv tshuab thev naus laus zis) lossis hla-qhov (hauv qhov-thev naus laus zis thev naus laus zis) siv los txuas lub cev thiab txuas hluav taws xob txuas ib feem rau lub rooj tsav xwm luam tawm.
Cov qauv av ntawm daim phiaj hluav taws xob sib xws qhov kev npaj ntawm cov coj ntawm ib feem.
Cia peb paub cov khoom, thiab nws yog hneev taw
Hauv cad tsim peb tuaj yeem faib cov khoom faib ua ob pawg loj
Thawj Nto Mount (SMD) cov khoom siv
Qhov thib ob dhau los ntawm cov khoom sib xyaw
Kauj Ruam 1: Cheeb Tsam SMD
Nto mount
kev sib dhos yog hais txog txheej txheem teeb tsa uas ntu ntu ntu lossis cov khoom siv saum npoo av (SMDs) tau teeb tsa ntawm lub rooj tsav khoom liab qab los ntawm cov laug muab tshuaj txhuam uas ua lub luag haujlwm ua kua nplaum rau lo ntu ntu ntu ntu rau board. Cov txheej txheem dav dav ntawm kev sib dhos saum npoo muaj cov kab laug sab muab luam tawm cov khoom sib dhos, kho qhov muag kho qhov muag (AOI), rov ua kom zoo dua qub, AOI lossis AXI thiab lwm yam.
Kauj Ruam 2: Los Ntawm Qhov Chaw
Kev siv thev naus laus zis dhau los (tseem sau "thru-hole"), hais txog cov txheej txheem kev teeb tsa siv rau cov khoom siv hluav taws xob uas koom nrog kev siv cov hlau lead ntawm cov khoom sib txuas uas tau tso rau hauv qhov qhov drilled hauv cov ntawv luam tawm Circuit Board (PCB) thiab muab tshuaj txhuam rau hauv sab nraud los ntawm phau ntawv sib dhos (tso rau ntawm tes) lossis los ntawm kev siv cov tshuab siv tshuab ntxhua khaub ncaws.
Kev sib dhos dhau los ntawm qhov yog hais txog cov txheej txheem uas dhau los ntawm cov khoom sib dhos tau muab tso rau ntawm lub rooj tsis muaj dab tsi los ntawm kev yoj yoj los yog siv tes ua ke nrog cov khoom siv coj mus los ntawm qhov drilled qhov ntawm PCB cov laug cam.
Kauj Ruam 3: Vim Li Cas Peb Xaiv Cov Hneev Taw Tshwj Xeeb?
Hneev taw ua rau peb paub qhov twg peb muab cov khoom sib dhos thiab nws ntseeg tau
1. thaj tsam ntawm PCB
2. tus nqi ntawm kev tivthaiv
3. tivthaiv (Los ntawm qhov, SMD)
4. Qhov muaj nyob ntawm cov khoom hauv zos
5. Daim ntawv thov PCB

Lub Tshuab Ntaus Ntawv - Tus Pabcuam Khoos Phis Tawj Khoos Phis Tawj: 7 Kauj Ruam (nrog Duab)
Lub Tshuab Ntaus Ntawv - Tus Pabcuam Khoos Phis Tawj Khoos Phis Tawj: Lub Tshuab Ntaus Ntawv yog tus pab tus kheej me me uas tuaj yeem tso saib ntau yam ntaub ntawv rub tawm los ntawm is taws nem. Cov cuab yeej no tau tsim thiab tsim los ntawm kuv rau CRT 420 - Chav Kawm Tshwj Xeeb Tshwj Xeeb ntawm Berry College uas yog Tus Thawj Coj

Hloov Cov Ncaj Ncaj Ncaj Ncaj Ncaj Ncaj Ncaj Ncaj Ncaj Ncaws Ncaws Ncaws Ncaws Ncaws Pob (hauv Pinch): Tom qab pom qhov kev tshaj tawm rau kev sib tw arduino, kuv hais tias, hav zoo vim li cas ho tsis sim. Yog li kuv kinda cheaped tawm thiab tau txais cov khoom siv pob txha liab qab, nrog lub hom phiaj ntawm "ua nws txoj hauv kev". Ib qho ntawm cov kev hloov pauv no yog ib yam ntawm thawj yam uas koj
