Taw qhia
Hauv kev tsim PCBA niaj hnub no, uas yog qhov tseem ceeb tshaj - cov xov hlau ceev, kev siv dav dav ntawm cov laug cam ntau, cov pob me me, thiab cov halogen nkig heev -dawb resins tau ua rau muaj kev nkag siab zoo ntawm Circuit Court boards rau cov neeg kho tshuab kev ntxhov siab. Hauv kev tshaj tawm -SMT xaiv thiab tso cov txheej txheem-xws li kev sib cais ntawm vaj huam sib luag tshuab, ICT/FCT kuaj, cua sov lub tog raj kheej clamping, thiab zaum kawg enclosure los ua ke- lub substrate raug rau ntau qib ntawm compression, dabtsi yog khoov, los yog torsion. Cov kev ua haujlwm macroscopic no txhais ua kev puas tsuaj loj heev ntawm qib microscopic, ua rau cov pob txha tawg hauv BGA cov pob qij txha thiab cov microcracks sab hauv hauv MLCC capacitors. Kev taw qhia txog kev ntsuas qhov ntsuas qhov ntsuas rov qab los ntsuas qhov ntsuas qhov ntsuas qhov ntsuas kev hloov pauv hloov pauv hauv lub sijhawm tiag tiag thaum cov txheej txheem tseem ceeb yog qhov tsim nyog rau kev cuam tshuam lub cev latent kev puas tsuaj thiab ua kom muaj kev ntseeg siab ntawm cov tub ntxhais PCBA cov khoom.
Mechanisms Mechanical Stress Damage thiab Hidden Failure Phenomena
Thaum lub sij hawm rov qab - kawg lub sij hawm sib dhos ntawm PCBA ua, luam ntawv Circuit Court boards feem ntau tiv taus lub cev loads los ntawm ntau yam automated mechanisms los yog phau ntawv compression. Thaum lub cuab yeej txiav ntawm lub vaj huam sib luag pom txiav rau hauv cov substrate cov ntsiab lus sib txuas, lossis thaum lub dab dej kub ceev nruj, tensile los yog shear stresses yog instantly generated hauv PCB. Txij li thaum lub elastic modulus ntawm cov hlau lead- dawb solder alloys thiab intermetallic compound txheej yog ho siab dua li ntawm lub hauv paus resin substrate, kev ntxhov siab yuav ua rau muaj concentrated nyob rau hauv cov ntaub so ntswg ntawm cov npoo ntawm lub Cheebtsam thaum sab nraud dabtsi yog khoov xaav ntau tshaj qhov kev txwv. Qhov no mechanical overload muaj feem ntau yuav ua rau muaj kev cuam tshuam tensile delamination tsis xws luag hauv cov ntaub qhwv, ua rau cov ntaub qhwv tooj liab tawg rau hauv cov ntawv nrog rau cov resin. Rau qhov loj, multilayer ceramic capacitors, kev ntxhov siab sab nraud tuaj yeem ua rau lawv cov qauv laminate sab hauv, ua rau cov khoom siv hluav taws xob me me ntawm 45-degree kaum sab xis uas tsis pom ntawm qhov muag liab qab. Cov kev tsis xws luag no yog tus cwj pwm los ntawm kev ncua qeeb heev; cov khoom lag luam ua tiav ib txwm ua thaum lub Hoobkas ua haujlwm sim tab sis tuaj yeem ntsib hluav taws xob tawg lossis hlawv ntawm qhov chaw tawg vim tias muaj dej nkag tau ntau lub hlis rau hauv kev pabcuam ntawm qhov kawg-tus neeg siv qhov chaw.
Txoj hauv kev ntawm Kev Tshawb Fawb Txog Kev Tshawb Fawb Kev Ntsuas thiab Kev Tiv Thaiv Kev Nyuaj Siab
Tus nqi tseem ceeb ntawm kev ntsuas ntsuas ntsuas yog nyob rau hauv kev hloov pauv microscopic, pom tsis pom cov tshuab deformation rau hauv cov digital, cov khoom siv hluav taws xob kom muaj nuj nqis. Cov kws kho mob feem ntau siv txoj cai -lub kaum sab xis rosette nrog peb -axis impedance ntawm 120 ohms. Siv cov nplaum tshwj xeeb cyanoacrylate, lawv ruaj khov rau hauv PCB nto nyob ib puag ncig cov khoom rhiab heev uas muaj feem cuam tshuam rau kev ntxhov siab puas tsuaj - feem ntau ntawm plaub fab ntawm BGAs loj lossis raws cov npoo ntawm cov pins ntawm cov txuas txuas ntev. Thaum lub PCBA raug khoov lub cev thaum lub sij hawm sib cais los yog sib dhos, lub microscopic tensile los yog compressive rog ntawm lub substrate nto yog ib txhij xa mus rau lub rhiab heev strain gauges. Cov strain gauges undergo geometric deformation, uas ua rau muaj kev hloov me ntsis hauv lawv qhov tseem ceeb tsis kam. Lub kaw lus xeem siv tus choj Wheatstone los ua kom nrov nrov qhov kev tawm tsam no, uas yog tom qab ntawd sau tseg hauv lub sijhawm tiag tiag los ntawm kev ntsuas qhov ntsuas nrog qhov siab -cov qauv ntsuas nrawm dua 10 kHz. Cov qauv lej tshwj xeeb yog siv los xam qhov tseeb tangential thiab ib txwm deformations ntawm lub rooj tsavxwm nto.
Yam yuav tsum tau ua kom muaj nuj nqis raws li IPC -JEDEC-9704A Standard
Nyob rau hauv kev soj ntsuam zoo rau automotive electronics, industrial tswj, thiab kev kho mob motherboards, strain gauge xeem yuav tsum tau ua raws li nruj me ntsis logic pib. Kev lag luam- lees paub tus qauv IPC-JEDEC-9704A qhia meej meej qhia cov txheej txheem rau kev tswj hwm PCB. Lub tuam tsev tswj xyuas kev ua tau zoo yuav tsum tau teeb tsa qhov Kev Tso Cai Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lawm Rau cov txheej txheem ib leeg nrog lub thickness ntawm 1.6 hli, qhov siab tshaj plaws microstrain tus nqi yuav tsum raug txwv nyob rau hauv lub 500 με qhov pib ntawm lub sij hawm ntawm downward siab thaum lub sij hawm sib cais vaj huam sib luag thiab kuaj fixture daim ntawv thov. Rau cov automotive tswj boards nruab nrog 0.5 hli nplua -pitch BGAs, qhov pib no yog nruj rau 300 με. Ib qho tseem ceeb tshaj qhov ntsuas qhov ntsuas yog qhov strain rate- uas yog, tus nqi ntawm microstrain hloov lub sijhawm-uas yuav tsum tau tswj qis dua 10,000 με / s. Yog tias qhov ntsuas qhov ntsuas dynamic tshaj qhov ntsuas no, nws qhia tau hais tias qhov kev txav txav hnyav dhau lawm, thiab cov cuab yeej siv tshuab koom nrog hauv cov txheej txheem yuav tsum raug kaw rau kev kho.
Xaus-rau-Xaum Kaw-Loop Optimization thiab thim rov qab zoo-Tau ntawm cov khoom siv thiab cov txheej txheem Parameters
Kev ntsuas ntsuas ntsuas tsis yog tsuas yog txheeb xyuas cov teeb meem muaj peev xwm, tab sis lub sijhawm muaj zog- kev ntxhov siab nthwv dej nws tsim los kuj yog cov ntaub ntawv tseem ceeb rau kev taw qhia kev txhim kho kev txhim kho thiab cov cuab yeej ua kom zoo. Thaum lub ntsuas ntsuas ntsuas pom qhov txawv txav ntawm lub microstrain waveform nyob rau lub sijhawm tiag tiag cov hniav tsis siv neeg tag nrho- hom PCB depaneling tshuab txiav rau hauv PCB, pab pawg txheej txheem yuav tsum tam sim ntawd nres kev tsim khoom thiab ua qhov kev soj ntsuam hauv paus. Los ntawm kev nplua - kho qhov siab ntawm lub vaj huam sib luag- cais lub tog raj kheej pneumatic - txo nws los ntawm 0.6 MPa mus rau 0.45 MPa- thiab txo qis cov kab nrawm nrawm los ntawm 30%, cov kws tshaj lij tuaj yeem ua lwm qhov kev sim SMT thiab saib xyuas tias cov kab mob sib kis rov qab mus rau qhov muaj kev nyab xeeb. Hais txog kev ua kom zoo ntawm ICT / FCT sojntsuam lub txaj, yog tias qhov kev poob qis ntawm qhov ntsuas qhov ntsuas ua rau muaj kev ntxhov siab hauv cheeb tsam, lub chaw haujlwm engineering yuav tsum, raws li cov lus pom los ntawm txhua txoj hauv kev ntawm cov ntsuas ntsuas, ua kom meej ntxiv qhov chaw txhawb nqa kab ntawm sab nraub qaum ntawm cov ntsiab lus ntawm kev ntxhov siab siab tshaj plaws kom ua tiav ntau- taw tes sib npaug ntawm lub cev deformation. Los ntawm qhov kev hloov pauv ntawm qhov kev hloov pauv no raws li cov ntaub ntawv ntawm lub cev deformation tiag tiag, kev paub txog kev tsim vaj tsev tau hloov mus rau hauv cov qauv nruj, muaj peev xwm tsim tau.
Los ntawm kev cia siab rau kev nthuav dav, kev tshawb fawb txog kev ntxhov siab muab los ntawm cov ntsuas ntsuas, zais cov khoom puas thaum lub rooj sib dhos thiab cov txheej txheem sib cais tuaj yeem raug tshem tawm tag nrho.nyob rau hauv cov kab ntau lawm, kom ntseeg tau tias siab - cov nqi chips nyob twj ywm thiab tsis zoo nyob rau hauv tag nrho lawv lub neej voj voog.
