Dab tsi yog cov txheej txheem rau SMT PCB los ua ke?
Cov txheej txheem ntawm kev siv SMT los tsim cov khoom siv PCB suav nrog kev siv cov tshuab tsis siv neeg los sib sau cov khoom siv hluav taws xob.Lub tshuab no tso cov ntsiab lus ntawm lub rooj tsav xwm hauv Circuit Court, tab sis ua ntej ntawd, cov ntaub ntawv PCB yuav tsum tau kuaj xyuas kom paub meej tias lawv tsis muaj teeb meem cuam tshuam rau kev tsim khoom thiab kev ua haujlwm ntawm lub cuab yeej.Tom qab lees paub tias txhua yam zoo tag nrho, cov txheej txheem ntawm SMT PCB sib dhos tsis txwv rau kev sib dhos thiab tso cov khoom lossis cov khoom sib txuas ntawm PCB.Cov txheej txheem tsim khoom hauv qab no kuj yuav tsum tau ua raws.
1. Siv cov tshuaj txhuam hniav
Thawj kauj ruam thaum sib sau ua ke SMT PCB pawg thawj coj saib yog siv cov tshuaj txhuam hniav.Cov tshuaj nplaum tuaj yeem siv rau PCB los ntawm kev siv tshuab silk screen.Nws tseem tuaj yeem siv tau siv PCB stencil tailored los ntawm cov ntaub ntawv CAD zoo sib xws.Koj tsuas yog yuav tsum tau txiav cov stencils siv lub laser thiab siv cov tshuaj txhuam hniav rau qhov chaw uas koj yuav solder cov khoom.Daim ntawv thov solder paste yuav tsum tau nqa tawm hauv qhov chaw txias.Thaum koj ua tiav daim ntawv thov, koj tuaj yeem tos qee lub sijhawm rau kev sib dhos.
2. Kev tshuaj xyuas koj cov tshuaj txhuam hniav
Tom qab cov tshuaj txhuam tau siv rau lub rooj tsavxwm, cov kauj ruam tom ntej yog yuav tsum tau kuaj xyuas nws los ntawm cov txheej txheem tshuaj xyuas cov txheej txheem.Cov txheej txheem no yog qhov tseem ceeb, tshwj xeeb tshaj yog thaum txheeb xyuas qhov chaw ntawm cov tshuaj txhuam hniav, tus nqi ntawm cov tshuaj txhuam hniav siv, thiab lwm yam.
3. Txheej txheem kev pom zoo
Tsuas yog nyob rau hauv rooj plaub koj lub rooj tsavxwm PCB siv SMT cov khoom ntawm ob sab, yuav tsum tau txiav txim siab rov ua dua cov txheej txheem rau kev lees paub thib ob.koj yuav tuaj yeem taug qab lub sijhawm zoo tshaj plaws los nthuav tawm cov tshuaj nplaum rau hauv chav tsev kub ntawm no.Qhov no yog thaum koj lub rooj tsav xwm Circuit Court npaj tau los ua ke.Cov khoom siv tseem yuav tau npaj rau lub Hoobkas tom ntej.
4. Cov khoom siv sib dhos
Qhov no pib ua haujlwm nrog BOM (Bill of Materials) siv los ntawm CM rau kev txheeb xyuas cov ntaub ntawv.Qhov no pab txhawb kev txhim kho ntawm BOM cov khoom siv sib dhos.
5. Cov khoom ntim khoom nrog cov khoom
Siv cov barcode rub tawm ntawm cov khoom lag luam thiab muab tso rau hauv cov khoom siv sib dhos.Thaum cov khoom tau muab tso rau hauv cov khoom siv tag nrho, lawv raug coj mus rau qhov chaw xaiv thiab muab lub tshuab hu ua nto mount technology.
6. Kev npaj cov khoom siv rau kev tso kawm
Ib lub cuab yeej xaiv thiab qhov chaw yog ua haujlwm ntawm no los tuav txhua yam khoom sib dhos.Lub tshuab kuj siv lub cartridge uas tuaj nrog lub cim tshwj xeeb uas sib haum rau BOM cov khoom siv sib dhos.Lub tshuab yog tsim los qhia qhov chaw uas lub cartridge tuav.
