HD TSIBblind buried hole circuit boards have become the core components of many high-end electronic products due to their excellent performance advantages. Cov txheej txheem saum npoo av (SMT), raws li cov txheej txheem tseem ceeb rau cov khoom siv hluav taws xob hluav taws xob rau hauv kev ua kom zoo thiab ua tau zoo ntawm cov khoom siv hluav taws xob.
Tus txheej txheem SMT ntawm HDI dig muag faus lub qhov Circuit Court Boards pib nrog kev npaj ntawm Cheebtsam. Firstly, nws yog qhov tsim nyog yuav nruj me ntsis npo thiab tshawb xyuas ntau yam khoom siv hluav taws xob kom ntseeg tau tias lawv qhov kev ua hluav taws xob raug, thiab tus lej PIN ua tau zoo. Rau me - cov chips thiab precision Cheebtsam, muaj cov chips, thiab halplanity deistors yog qhov tseem ceeb rau ib qho tseem ceeb. Me tsis xws luag nyob rau hauv cov feem no tuaj yeem ua rau cov kev sib tw tsis zoo, lossis qhib cov txheej txheem txuas ntxiv, yog li cuam tshuam rau kev ua haujlwm ntawm tag nrho cov Circuit Court Board.
Hais txog cov khoom siv mounting, siab - Precision nto yog cov khoom siv tseem ceeb ntawm HDI dig muag Buried Boards. Cov hom npoo npoo mount tshuab feem ntau muaj kev pom zoo lees paub cov ntaub ntawv ntawm cov duab hauv Circuit Court thiab cov khoom sib xyaw ua ke ntawm cov khoom siv lossis cov kev muab tso rau qhov tseeb kom ncav tau micrometer. Los ntawm kev tswj hwm kev tswj hwm, lub tshuab mount raug kom raug cov kab xev los ntawm daim kab xev lossis tais lawv rau ntawm txoj haujlwm ntawm Circuit Court ntawm kev kub ceev thiab raug. Piv txwv li, hauv cov txheej txheem ntau lawm ntawm cov khoom siv smartphone, thiab qhov sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv thiab cov kev ua tau zoo ntawm Circuit Court.
Tom qab cov Cheebtsam tau muab tso rau ntawm Circuit Courruit Board, tus txheej txheem samling ua ib kauj ruam tseem ceeb hauv kev ntseeg tau ntawm cov hluav taws xob sib txuas. Rau SMT SOLDERING ntawm HDI dig muag faus rau Circuit Court Boards, cov txheej txheem yog xav sib zog nqus. Thaum lub sij hawm ua kom cov txheej txheem soldering, cov Circuit Court Board ua ntej los ntawm kev daws teeb meem aws, ua rau cov flux muab tso rau hauv cov txheej txheem txuas ntxiv. Raws li Cirtric Board nkag mus rau hauv thaj chaw soldering, qhov ntsuas kub tau txuas rau hauv cov nyom thiab cov qauv zoo sib txuas, khov kho cov pob qij txha zoo, ua kom cov khoom sib xyaw ua ke rau cov ntaub qhwv thaiv rau ntawm Circuit Court Board. Yog kev tswj hwm ntawm qhov kub nyhiab kub yog qhov tseem ceeb hauv cov txheej txheem no, raws li sib txawv thiab solder yuav xav tau qhov kub hnyav kom ntseeg tau tias veel zoo. Rau qee qhov kub rhiab, xws li preciset kub sensor chips, muaj qhov ntsuas kub siab dua thiab kho kom tsis txhob muaj kub siab los ntawm kev ua kom cov khoom siv ua kom puas tsuaj; Rau qee qhov loj-} {{txheej txhim kho cov ntaub qhwv ntsej muag, thiab txhim kho cov tshuab ua kom tau zoo thiab ua tau zoo ntawm cov pob qij txha sib dhos.
Ntxiv rau, kev tshuaj xyuas zoo thiab kev tswj tau yog kev sib xyaw thoob plaws hauv tag nrho cov txheej txheem SMT. Ntau txoj kev kuaj pom tau siv dav, los ntawm AoI (automates soj ntsuam) ntawm}} ray soj ntsuam tom qab soldering. AOI cov txheej txheem siv kho qhov ntsuas siv kho qhov muag kom pom tau txoj haujlwm, offset, polarity, thiab txawm hais tias muaj qhov ploj ntawm cov khoom siv mounted. Thaum pom qhov txawv txav, lawv tuaj yeem raug kho lossis rov ua haujlwm raws sijhawm. X - Kev tshuaj ntsuam hluav taws xob yog tsuas yog siv los kuaj qhov zoo ntawm cov pob qij txha sib dhos hauv BGA thiab lwm yam ntim khoom siv. Los ntawm x {- Cov duab tshav kub nkag mus rau cov pob qij txha, kom pom qhov sib txuas ntawm cov yas, kom pom qhov sib txuas hluav taws xob zais thiab kev ntseeg tau zoo.
