Cov yam ntxwv ntawm cov cuab yeej siv hauv tsev board los ua ke suav nrog cov hauv qab no:
Ua neeg ua hauj lwm
1, miniaturization thiab me me:
Tsev neeg cov khoom siv hauv tsev neeg muaj kev coj ua Qhov ntim ntawm cov nplaim taw saum npoo av siv yog ntau dua li ntawm cov khoom sib sau, feem ntau txo los ntawm 60% rau 90%, thiab qhov hnyav kuj tau txo los ntawm 60% rau 90%. Qhov kev tsim qauv miniaturization no ua rau cov neeg siv hauv tsev neeg yuav tsum tau kev cog lus ntau ntxiv, sib ntsib cov tsev neeg niaj hnub 'xav tau cov khoom me me.
2, siab sib dhos ua kom ntev:
Vim yog qhov loj me me ntawm SMT Cheebtsam, lawv tuaj yeem raug npaj ntau dua ntawm tus PCB, yog li txuag tau cov haujlwm Circ, kom ua ke kom muaj kev sib xyaw ua ke. Qhov kev sib dhos siab zoo no pab ua cov khoom siv hauv tsev neeg yuav tsum tau tsim ntau dua li kev sib raug zoo thiab nrog cov haujlwm nplua nuj.
3, Kev Ua Hluav Taws Xob Zoo Tshaj:
Cov pins los yog terminals ntawm smt Cheebtsam yog ncaj qha rau saum npoo ntawm pcb, muaj kev sib tw luv luv. Qhov no txo cov paib kev ua kom pom tseeb thiab kev cuam tshuam thaum kis tau mob, uas yog qhov tshwj xeeb tshaj plaws ntawm cov khoom siv hluav taws xob hauv tsev.
4, automation muaj zog automation ntau lawm:
SMT Patch Kev ua yog tsim rau kev tsim khoom. Cov txheej txheem thiab kev ua haujlwm ntawm qhov loj me ntawm cov npoo npoo av, ntxiv rau qhov sib xws ntawm cov kev mob soldering, ua rau qib kev hloov kho siab heev. Qhov no tsis tsuas yog txhim kho kev ua tau zoo tab sis kuj tseem txo cov nqi tsim khoom.
5, Ib puag ncig tus phooj ywg:
SMT Patch Ua Kev Siv Reflow soldering thev naus laus zis, tsim cov roj tsis muaj roj tsis zoo thiab cov khoom seem. Nrog rau kev siv thoob plaws ntawm txhuas tsis muaj txhuas, smt bood kev ua phooj ywg, ntsib cov tsev neeg niaj hnub ua rau kev tiv thaiv ib puag ncig.
6, siab ntseeg tau:
Cov khoom siv smt yog khov kho, tsis muaj kev ua lossis luv luv, txo qhov kev pheej hmoo ntawm kev sib koom ua ke ntawm cov khoom sib koom tes ntawm cov khoom siv hluav taws xob. Ib qho ntxiv, cov khoom sib tw smt muaj kev co ua kom muaj zog thiab haum rau cov khoom siv hauv tsev neeg uas xav tau kev ruaj khov.
7, nqi nyiaj-ua tau zoo:
Txawm hais tias thawj zaug kev nqis peev nyob rau hauv ib tug kab ntau lawm yog tus nqi siab, nws cov peev txheej siab yuav ua haujlwm tau zoo txo tus nqi tsim khoom ntev. Nyob rau tib lub sijhawm, SMT sib dhos txo cov khoom siv pov tseg thiab tus nqi ntawm cov khoom tsis xws luag, txuas ntxiv txo tus nqi tag nrho, ntxiv qis dua cov nqi tag nrho.
Cov txheej txheem ntawm cov cuab yeej siv hauv tsev board los ua ke suav nrog cov kauj ruam hauv qab no:
▲ 1, PCB tsim:Firstly, siv Circuit Court tsim software (xws li Altium tsim qauv, dav hlau, thiab lwm yam) kom ua tiav cov qauv ntawm Circuit Court Board. Thaum lub sij hawm tsim qauv, xyuas kom meej tias kev teeb tsa cov hluav taws xob hluav taws xob yog qhov tsim nyog thiab yooj yim rau cov npoo mounting. Tom qab tus qauv tsim tiav, tsim cov ntaub ntawv ntau lawm suav nrog cov ntaub ntawv gerber, tho kev kos duab, thiab lwm yam khoom siv (BOM), thiab lwm yam kev npaj.
▲ 2, PCB tsim:Raws li cov qauv tsim qauv, tus pcb chaw tsim tshuaj paus yog muab tso ua ke los tsim cov boardcuit Co board. Qhov no suav nrog cov txheej txheem xws li cov khoom xaiv, Photolithography, etching, drilling, thiab kev kho kom nto ntawm Circuit Court Board.
▲ 3, Nto Roob Tshuab (SMT):
● A, solder muab tshuaj txhuam luam ntawv: minectormly luam tawm cov tshuaj txhuam hniav rau cov tshuaj tiv thaiv kab ke, yog li kev faib tawm ntawm cov khoom siv sib xyaw lossis cov duab.
● B, Cheebtsam sib tshooj: Cov khoom sib dhos saum npoo av (smds) yog precisely muab tso rau cov tshuaj txhuam paste-coated ntaub siv lub tshuab tso pa. Niaj hnub kev tso cav feature ceev thiab qhov tseeb, muaj peev xwm ntawm kev tiv thaiv me me los ntawm cov kav dej me me thiab capacitors kom ua ke sib xyaw ua ke.
● C, Reflow Soldering: Tom qab cov khoom siv tau muab tso rau, cov Circuit Court Board mus dhau ib txoj kev cuam tshuam nrog soldering soldering. Lub qhov cub maj mam muab cov Circuit Coasts Cov Circuit Coilcuit Board rau lub ntsiab lus melting ntawm cov hamtaptape ntawm cov cam thiab khov kho txuas cov khoom siv rau PCB cov ntaub qhwv.
▲ 4, Kev Soj Ntsuam Zoo:Tom qab referge soldering ua tiav, muaj ib qho kev tshuaj xyuas zoo yog nqa tawm ntawm Circuit Court Board kom paub meej tias txhua tus neeg raug teeb tsa raug teeb tsa thiab soldered khov kho. Cov Kev Ntsuam Xyuas Feem Ntau suav nrog AOI (Automated Eventionment), X-ray Xyuas, thiab kev sim ua haujlwm.
▲ 5, Kev Ntsuas Xyuas Haujlwm:Lub hwj chim-ntawm kev sim ntawm Circuit Court board kom ntseeg tau tias txhua feem ua haujlwm tau zoo thiab ua raws cov qauv tsim.
▲ 6, Hauv peb lub tuam txhab, cov cuab yeej cuab yeej siv hauv tsev, cov cuab yeej siv hauv tsev los ua ke suav nrog cov neeg cheb tsev hauv av pem teb thiab pleev cov tshuab pcb pcb los ua ke.
