Txhim kho lub rooj tsav xwm luam tawm (PCB) hauv ib lub thawv yog ib kauj ruam tseem ceeb hauv kev ua haujlwm kom raug thiab tiv thaiv cov khoom siv hluav taws xob.Hauv tsab ntawv tshaj tawm no, peb yuav piav qhia txog cov kauj ruam tsim nyog thiab cov lus qhia los pab koj txhim kho PCBs hauv cov ntaub thaiv kom nyab xeeb thiab ua tau zoo.
1. Kev npaj layout:
Kev npaj ua tib zoo yuav tsum tau kos ua ntej mounting PCB rau hauv lub thawv.Txiav txim siab qhov chaw ntawm cov khoom ntawm PCB kom ua kom zoo dua qhov chaw siv nyob rau hauv lub thawv.Xav txog qhov loj thiab cov duab ntawm lub thawv kom paub meej tias nws muaj qhov qhib qhov yuav tsum tau muaj rau cov connectors thiab interfaces.
2. Tshawb xyuas lub thawv:
Ua tib zoo tshuaj xyuas lub thawv rau txhua qhov kev puas tsuaj lossis qhov tsis xws luag uas tuaj yeem cuam tshuam cov txheej txheem kev teeb tsa lossis kev ua haujlwm ntawm PCB.Xyuas kom cov ntaub ntawv huv si thiab tsis muaj cov khib nyiab lossis lwm yam khoom txawv teb chaws uas yuav cuam tshuam rau kev teeb tsa.
3. Npaj PCB:
Npaj PCB los ntawm kev ntxuav nws nrog ib daim ntaub antistatic los yog cov khoom siv hluav taws xob.Xyuas kom tseeb tias tag nrho cov khoom yog soldered kom zoo thiab nrees txuas nrog lub rooj tsavxwm.Muab ob npaug rau cov kev sib txuas xoob lossis luv luv uas tuaj yeem ua teeb meem thaum txhim kho.
4. Siv rwb thaiv tsev:
Txhawm rau tiv thaiv luv luv Circuit Court thiab tiv thaiv PCB los ntawm ya raws lossis lwm yam ib puag ncig, nws raug nquahu kom siv cov khoom siv insulating xws li txheej nyias ntawm silicone los yog nplaum-rov qab insulating ua npuas ncauj rau hauv qab ntawm PCB.Qhov no tseem yuav muab cov cushioning thiab tiv thaiv kev sib txhuam lossis kev co ntawm PCB thiab rooj plaub.
5. Kho lub PCB:
Siv cov khoom siv txhim kho tsim nyog, ua tib zoo muab PCB tso rau hauv qhov chaw xav tau hauv qhov chaw kaw.Nyob ntawm qhov loj thiab qhov nyuaj ntawm PCB, koj tuaj yeem siv cov hlua khi, cov ntsia hlau, lossis cov hlua khi.Xyuas kom PCB nruj, tab sis yuav tsum ceev faj tsis txhob overtighten cov screws vim qhov no yuav ua rau lub PCB puas los yog ntxhov siab rau cov khoom.
6. Tsim kom muaj av av:
Grounding yog qhov tseem ceeb los tshem tawm cov hluav taws xob hluav taws xob thiab tiv thaiv kev puas tsuaj rau PCB thiab nws cov khoom.Siv cov hlua hauv av los yog pluaj hauv av los txuas rau hauv av taw tes ntawm PCB rau rooj plaub kom muaj kev ruaj ntseg thiab txhim khu kev qha hluav taws xob.Cov kauj ruam no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov khoom siv nrog cov khoom siv hluav taws xob uas xav tau kev tiv thaiv ntxiv los ntawm kev cuam tshuam sab nraud.
7. Kev kuaj kom haum thiab ua haujlwm:
Tom qab lub PCB raug teeb tsa, ua qhov kev ntsuam xyuas kom paub tseeb tias nws haum thiab ua haujlwm.Nco ntsoov tias tag nrho cov connectors, keyboards, thiab cov chaw nres nkoj sib haum nrog cov qhov qhib hauv tsev.Kev sim ua haujlwm yog ua kom paub meej tias cov khoom thiab tag nrho cov haujlwm ua haujlwm raws li qhov xav tau.
Mounting PCB nyob rau hauv ib lub thawv yog ib qho tseem ceeb tsim cov kauj ruam uas cuam tshuam ncaj qha rau kev ntseeg tau thiab kev ua tau zoo ntawm cov khoom siv hluav taws xob.Los ntawm kev ua raws li cov kauj ruam uas tau teev tseg hauv phau ntawv qhia no, koj tuaj yeem ntseeg siab thiab ua tau zoo mount PCB, ua kom muaj kev nyab xeeb thiab muaj txiaj ntsig kev koom ua ke hauv lub kaw lus.Nco ntsoov npaj qhov kev teeb tsa, tshuaj xyuas lub kaw lus, npaj PCB, siv cov rwb thaiv tsev, tiv thaiv PCB, tsim kom zoo hauv av, thiab xyuas kom haum thiab ua haujlwm zoo.Ua raws li cov kev ceev faj tsim nyog no yuav pab koj tsim cov rooj sib tham uas muaj zog, tiv thaiv koj lub PCB, thiab ua rau muaj kev vam meej tag nrho ntawm koj qhov project electronics.
