Dab tsi yog Qhov Zoo Ntawm SMT Patch Processing Technology
Dab tsi yog qhov zoo ntawm SMT thaj ua haujlwm thev naus laus zis
1. Cov khoom siv hluav taws xob yog qhov me me thiab siab hauv kev sib dhos ceev
Qhov ntim ntawm SMT thaj thaj tsam tsuas yog kwv yees li 10% ntawm cov khoom ntim khoom ib txwm muaj, thiab qhov hnyav tsuas yog 10% ntawm cov tsoos plug-in cov khoom. SMT tshuab feem ntau tuaj yeem txo qhov ntim ntawm cov khoom siv hluav taws xob los ntawm 40% mus rau 60%, txo qhov zoo ntawm 60% mus rau 80%, thiab txo qhov chaw thiab qhov hnyav. Daim phiaj ntawm SMT nti ua thiab cov khoom sib dhos tau tsim los ntawm 1.27mm mus rau 0.63mm daim phiaj tam sim no, thiab qee qhov tau mus txog 0.5mm daim phiaj. Los ntawm-qhov mounting tshuab yog saws los ua kom sib dhos ceev.
2. Muaj kev ntseeg siab thiab muaj zog tiv thaiv kev vibration
SMT chip processing siv cov khoom siv nti, uas muaj kev ntseeg siab, me me, lub teeb yuag, muaj zog vibration tsis kam, tsis siv neeg ntau lawm, kev txhim kho siab, thiab tus nqi ntawm cov pob qij txha tsis zoo yog feem ntau qis dua 10 feem ntawm ib lab. Kev siv thev naus laus zis ntawm cov khoom siv los ntawm lub qhov yog qhov kev txiav txim siab qis dua, uas tuaj yeem ua kom ntseeg tau tias qhov tsis xws luag ntawm cov pob qij txha ntawm cov khoom siv hluav taws xob lossis cov khoom siv. Tam sim no, ze li ntawm 90% ntawm cov khoom siv hluav taws xob siv SMT thev naus laus zis.
3. Cov yam ntxwv zoo siab zaus thiab ua haujlwm tau zoo
Vim hais tias cov khoom siv nti tau ruaj khov, cov khoom siv feem ntau yog cov hlau lead lossis luv luv, uas txo cov kev cuam tshuam ntawm parasitic inductance thiab parasitic capacitance, txhim kho cov yam ntxwv ntawm lub voj voog, thiab txo cov electromagnetic thiab xov tooj cua zaus cuam tshuam. Qhov siab tshaj plaws ntawm lub voj voog tsim nrog SMC thiab SMD tuaj yeem ncav cuag 3 GHz, thaum lub nti tivthaiv tsuas yog 500 MHz, uas tuaj yeem ua rau lub sijhawm sib kis qeeb. Nws tuaj yeem siv rau hauv circuits nrog lub moos zaus tshaj 16MHz. Yog tias MCM thev naus laus zis tau txais, qhov siab tshaj plaws moos zaus ntawm lub koos pij tawj ua haujlwm tuaj yeem ncav cuag 100 MHz, thiab kev siv hluav taws xob ntxiv los ntawm cov kab mob parasitic tuaj yeem raug txo los ntawm 2-3 zaug.
4. Txhim kho kev tsim khoom thiab paub txog kev tsim khoom tsis siv neeg
Tam sim no, txhawm rau kom paub txog qhov ua tiav ntawm kev ua tiav ntawm kev teeb tsa lub rooj tsav xwm perforated, nws yog ib qho tsim nyog yuav tsum tau nthuav dav thaj tsam ntawm cov ntawv luam tawm thawj zaug los ntawm 40%, kom lub taub hau ntawm lub taub hau tsis siv neeg ntsaws tuaj yeem ntxig cov khoom, txwv tsis pub muaj yuav tsis txaus clearance thiab cov khoom yuav puas. Lub tshuab tsis siv neeg muab tso rau (SM421 / SM411) siv lub tshuab nqus tsev nqus los khaws thiab tso cov khoom, thiab lub tshuab nqus tsev nqus tsev me me dua li cov duab ntawm cov khoom, uas ua rau muaj qhov ntom ntom ntom ntom. Qhov tseeb, cov khoom me me thiab cov khoom siv zoo QFP yog tsim los ntawm cov tshuab tsis siv neeg muab tso rau kom ua tiav cov kab ntau lawm.
5. Txo cov nqi thiab txo cov nqi
(1) Qhov chaw siv ntawm cov ntawv luam tawm raug txo, thiab thaj tsam yog 1/12 ntawm kev siv tshuab los ntawm lub qhov. Yog tias CSP raug teeb tsa, thaj chaw yuav raug txo kom tsawg;
(2) Txo tus naj npawb ntawm qhov drilling hauv cov ntawv luam tawm thiab txuag cov nqi rov ua haujlwm;
(3) Vim yog kev txhim kho ntawm cov yam ntxwv zaus, tus nqi ntawm Circuit Court debugging raug txo;
(4) Vim qhov me me thiab lub teeb yuag ntawm cov khoom siv nti, tus nqi ntawm kev ntim khoom, kev thauj mus los thiab kev khaws cia raug txo;
SMT nti ua tshuab tuaj yeem txuag cov ntaub ntawv, lub zog, cov khoom siv, cov neeg ua haujlwm, lub sijhawm, thiab lwm yam, thiab tus nqi yuav raug txo mus txog 30% thiab 50%.
