PCBA DIP txheej txheem ntau lawm
Baiqiancheng tau tsom mus rau kev tswj hwm thiab tswj cov txheej txheem tsim khoom, nruj me ntsis tswj txhua qhov txuas ntawm kev tsim khoom, thiab xyuas kom meej tias qhov kev ntsuam xyuas muaj tseeb ua ntej xa mus rau cov neeg siv khoom.
1. Ua ntej ua ntej ua cov khoom sib xyaw, cov neeg ua haujlwm hauv chav ua haujlwm khaws cov khoom siv los ntawm cov khoom siv raws li BOM daim nqi ntawm cov ntaub ntawv, ua tib zoo xyuas cov qauv ntawm cov khoom thiab cov lus qhia tshwj xeeb, cov paib, thiab ua ntej ua cov khoom raws li tus qauv, siv tsis siv neeg. bulk capacitor txiab, transistors Tsis siv neeg moulding tshuab, tsis siv neeg siv tshuab moulding tshuab thiab lwm yam khoom siv molding rau kev ua;
2. Muab cov nplaum nplaum uas kub kub, nkag rau hauv lub rooj tsavxwm→muab cov nplaum nplaum kub kub, thiab thaiv cov tin-plated los ntawm qhov thiab cov khoom uas yuav tsum tau soldered tom qab;
3. Cov neeg ua haujlwm DIP plug-in ua haujlwm yuav tsum tau hnav lub nplhaib electrostatic tiv thaiv hluav taws xob zoo li qub. Raws li cov khoom BOM daim ntawv teev npe thiab daim ntawv qhia me ntsis tus lej, lub plug-in yuav tsum tau ua tib zoo thiab ua tib zoo ntxig, thiab tsis muaj qhov yuam kev los yog to;
4. Rau cov khoom siv ntxig, nws yog ib qho tsim nyog yuav tsum tau kuaj xyuas, feem ntau yog los xyuas seb cov khoom puas tau ntxig tsis raug lossis tsis raug;
5. Rau lub rooj tsavxwm PCB uas tsis muaj teeb meem nrog lub plug-in, cov kauj ruam tom ntej yog yoj soldering, thiab lub yoj soldering tshuab yog siv rau tag nrho-round tsis siv neeg soldering ua kom ruaj ntseg cov khoom;
6. Tshem tawm cov nplaum nplaum uas kub kub, thiab tom qab ntawd tshuaj xyuas nws. Hauv qhov txuas no, nws yog qhov kev tshuaj xyuas qhov muag. Saib xyuas seb lub welded PCB pawg thawj coj saib puas zoo los ntawm qhov muag liab qab;
7. Kev kho qhov vuam thiab kev kho yuav tsum tau ua rau lub rooj tsavxwm tsis muaj kev tiv thaiv PCB kom tsis txhob muaj teeb meem;
8. Tom qab vuam, uas yog txheej txheem txheej txheem rau cov khoom siv tshwj xeeb, vim tias qee cov khoom siv tsis tuaj yeem ncaj qha welded los ntawm yoj vuam tshuab raws li cov kev txwv ntawm cov txheej txheem thiab cov ntaub ntawv, thiab yuav tsum tau ua manually;
9. Rau PCB pawg thawj coj saib tom qab tag nrho cov khoom yog welded, yuav tsum tau ua ib qho kev ntsuam xyuas ua haujlwm los kuaj seb txhua qhov kev ua haujlwm zoo li cas. Yog tias pom muaj qhov ua haujlwm tsis zoo, nws yuav tsum tau kho thiab rov kuaj dua.
