PCB vaj huam sib luagtxoj cai thiab txoj kev
1. Raws li cov txheej txheem yuav tsum tau ua ntawm cov khoom sib dhos sib txawv, qhov siab tshaj plaws thiab qhov tsawg kawg nkaus ntawm lub vaj huam sib luag yuav tsum tau nkag siab meej.Feem ntau, PCB me dua 80X80mm yuav tsum tau panelized, thiab qhov siab tshaj plaws yog nyob ntawm lub peev xwm ntawm lub Hoobkas.Hauv luv luv, pcb loj yuav tsum ua tau raws li qhov yuav tsum tau uaCov khoom siv SMTfittings, uas yog conducive rau SMT thaj ua thiab pab txiav txim siab thickness ntawm lub PCB board.
2. Kev sib sau ua ke thiab kev sib sau ua ke yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm DFM thiab DFA, thiab tib lub sijhawm kom ntseeg tau tias lub rooj sib dhos PCB raug kho thiab tsis yooj yim deformed tom qab muab tso rau ntawm qhov sib dhos.Qhov sib faib zawj ntawm cov vaj huam sib luag yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm qhov chaw tiaj tus thaum lub sijhawmPCBAkev ua chip.
3. Hauv PCB vaj huam sib luagtsim, kev npaj ntawm cov khoom yuav tsum tsis txhob sib cais kev ntxhov siab thiab ua rau cov khoom tawg.Kev siv cov qauv vaj huam sib luag ua ntej tuaj yeem txo qhov kev sib tw thiab deformation thaum lub sij hawm sib cais ntawm pawg thawj coj saib, thiab txo qhov kev ntxhov siab ntawm cov khoom.Yam tsawg kawg nkaus, sim tsis txhob muab qhov tseem ceebcov khoomtom ntej nomus rau sab txheej txheem.
4. Qhov loj thiab daim ntawv ntawm lub vaj huam sib luag yog ua raws li qhov project tshwj xeeb, thiab cov qauv tsim yog ze li ntawm 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. Thaum cov txheej txheem ntawm board ntug connector tshaj qhov cuam tshuam ntawm ntau lub rooj sib koom ua ke, nws tau daws los ntawm kev sib hloov ntawm kev sib koom ua ke + txheej txheem sab los tiv thaiv qhov tsis zoo ntawm kev sib tsoo puas tsuaj thaum lub sijhawm sib kis lossis tuav cov txheej txheem.tom qab vuam.
6. Tom qab lub vaj huam sib luag tsim, nws yuav tsum tau ua kom ntseeg tau tias lub ntug ntawm qhov taw qhia ntawm lub rooj tsavxwm loj yog tsawg kawg yog 3.5 hli ntawm ntug ntawm lub rooj tsavxwm (qhov tsawg kawg nkaus ntawm lub tshuab clamping ntug ntawm PCB yog 3.5 hli. ), thiab ob kab pheeb ces kaum siv rau ntawm lub rooj tsavxwm loj tsis tuaj yeem muab tso rau symmetrically.Tsis txhob tso cov ntsiab lus siv symmetrically, kom rov qab / rov qab sab ntawm PCB tuaj yeem nkag mus rau lub tshuab los ntawm kev txheeb xyuas cov haujlwm ntawm lub cuab yeej nws tus kheej.
7. Thaum lub thickness ntawm lubPCB pawg thawj coj saibyog tsawg dua 1.0 hli, lub zog ntawm tag nrho cov vaj huam sib luag board yuav txo tau zoo heev (tsis muaj zog) thaum lub splicing sib koom los yog v-txiav zawj ntxiv, vim V-txiav qhov tob yog 1/3 ntawm board thickness, nruab nrab ntawm PCB lub rooj tsavxwm yog siv rau lub zog, thiab ib feem ntawm cov pob txha txhawb nqa - cov iav fiber ntau V yog tawg, uas ua rau lub zog softening.Yog tias nws tsis tau txais kev txhawb nqa los ntawm jig, nws yuav cuam tshuam rau cov txheej txheem hauv qab ntawm PCBA.
8. Thaum muajntiv tes kubntawm PCB, feem ntau muab cov ntiv tes kub rau sab nraud ntawm lub rooj tsavxwm nyob rau hauv cov kev taw qhia ntawm txoj hauj lwm tsis-splint.Ntug ntawm tus ntiv tes kub tsis tuaj yeem raug spliced lossis ua tiav.
