Pawg vaj huam sib luagcov cai thiab cov hau kev
1. Raws li cov txheej txheem uas yuav tsum tau ua ntawm cov chaw sib txawv sib txawv, qhov siab tshaj plaws thiab tsawg kawg ntawm cov vaj huam sib luag yuav tsum to taub. Feem ntau, PCB me dua 80xx80mm yuav tsum muaj kev sib raug zoo, thiab qhov loj tshaj yog nyob ntawm kev ua tau muaj peev xwm ntawm lub Hoobkas. Hauv luv luv, PCB loj yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawmCov Khoom Siv SMTCov fittings, uas yog conducive rau smt thaj ua thiab pab los txiav txim siab tuab ntawm PCB Board.
2. Cov kev sib dhos thiab cov rooj sib dhos yuav tsum ua kom tau raws li DFM thiab DFA, thiab tib lub sijhawm kom paub tseeb tias yog qhov yooj yim deformed tom qab tau muab tso rau ntawm fixture. Tus nyiam sib faib ntawm cov vaj huam sib luag yuav tsum ua kom tau raws li cov tiaj tiaj tus uas yuav tsum tau ua rau saum npooPcbaNti ua.
3. Hauv PCB vaj huam sib luagkev tsim ua, kev npaj ntawm cov Cheebtsam yuav tsum tsis txhob ua rau cais thiab ua rau tiv thaiv kab nrib pleb. Kev siv cov qauv vaj huam sib luag ua ntej muaj peev xwm txo qis warpage thiab deformation thaum lub rooj sib cais sib cais, thiab txo cov kev ntxhov siab ntawm cov khoom sib cais. Rau yam tsawg kawg nkaus, sim tsis txhob tso cov txiaj ntsigCheebtsamnpuabrau cov txheej txheem sab.
4. Qhov loj thiab daim ntawv ntawm vaj huam sib luag tau daws raws li qhov project tshwj xeeb, thiab cov tsos tsim yog ze rau lub square li sai tau. Nws raug pom zoo kom siv 2 × 2 lossis 3 × 3 Vaj huam sib luag txoj kev. Nws tsis pom zoo kom ua ke yin thiab yang panels yog tias nws tsis tsim nyog;
5.Tom qab vuam.
6. Tom qab cov pab pawg tsim, nws yuav tsum tau ua kom muaj tseeb tias txoj kev siv clamping ntawm lub rooj tsavxwm ntawm tus PCB yog 3.5mm), thiab ob daim kab pheeb ces kaum ntawm lub rooj sib tham loj tsis tuaj yeem muab tso rau symmetrically. Tsis txhob tso cov ntsiab lus siv rau cov ntsiab lus, yog li ntawd rov qab / sab nraud ntawm PCB tuaj yeem nkag mus hauv lub tshuab los ntawm kev txheeb xyuas nws tus kheej.
7. Thaum tuab ntawm lubPCB BoardYog tsawg dua 1.0mm, lub zog ntawm tag nrho pawg Vaj Huam Sib Luag yuav tau txais kev sib tw yog 1/3 ntawm lub hnab ntim pcb yog ntxiv, thiab ib feem ntawm cov fiber ntau lub pob txha yog ntxiv, thiab ib feem ntawm cov fiber ntau pob qij txha Yog tias nws tsis txaus siab los ntawm Jig, nws yuav cuam tshuam cov txheej txheem hauv qab PCBA.
8. Thaum muajtus ntiv tes xoo kubNyob rau PCB, feem ntau muab cov ntiv tes kub rau sab nraud ntawm pawg thawj coj ntawm cov kev coj ntawm txoj haujlwm tsis yog splint. Tus ntug ntawm cov ntiv nplhaib tsis tuaj yeem ua tiav lossis ua tiav.
