Evertiq yav dhau los tau tshaj tawm cov ntawv xov xwm saib thoob ntiaj teb kev lag luam semiconductor los ntawm kev xav ntawm cov neeg xa khoom. Nyob rau hauv cov koob no, lub qhov hluav taws xob tau mus txog rau cov khoom siv hluav taws xob cov khoom siv hluav taws xob thiab cov kws tshaj lij kev yuav khoom kom tsom mus rau qhov tsis txaus ntawm cov khoom siv hluav taws xob tam sim no thiab lawv ua dab tsi kom tau raws li cov neeg siv khoom xav tau. Lub sijhawm no lawv xam phaj Colin Strother, tus lwm thawj coj ntawm Rochester Electronics, nyob hauv Massachusetts.
Q: Qhov xwm txheej ntawm cov khoom siv tau zoo zuj zus ntxiv txij li muaj kev sib kis. Koj yuav piav qhia txog kev ua haujlwm li cas xyoo dhau los?
A: Cov teeb meem ntawm kev xa khoom ntawm ob xyoos dhau los tau ua rau muaj qhov tsis zoo ntawm kev xa khoom. Kev cuam tshuam hauv kev tsim khoom, kev thauj mus los thiab txawm tias muaj kev puas tsuaj ntuj thaum muaj kev sib kis tau ua rau muaj kev tsis txaus ntseeg ntawm cov saw hlau thiab lub sijhawm xa khoom ntev dua. Muaj 15% nce ntxiv hauv cov lus ceeb toom kaw rau tib lub sijhawm, vim muaj kev hloov pauv hauv qhov tseem ceeb ntawm cov nroj tsuag thib peb thiab kev lag luam rov tsom mus rau kev nqis peev ntawm cov nroj tsuag hauv kev teb rau kev tswj hwm ntawm cov roj teeb hluav taws xob tsawg. Tam sim no, kev lag luam semiconductor tsis txaus yog qhov xwm txheej tshwm sim.
Rochester Electronics 'ua kom pom tseeb ntawm cov khoom siv txuas ntxiv ntawm cov khoom siv hluav taws xob sib txuas zoo nrog lub neej ntev ntawm cov khoom siv khoom lag luam. Peb yog 100% ntawv tso cai los ntawm ntau tshaj 70 semiconductor manufacturers thiab muaj cov khoom muag ntawm ob qho tib si undiscontinued thiab discontinued Cheebtsam. Hauv paus, peb muaj peev xwm los txhawb peb cov neeg siv khoom xav tau nyob rau lub sijhawm ntawm cov khoom lag luam tsis txaus thiab kev ua tsis tiav, thiab qhov ntawd yog qhov peb tau ua nrog ntau tshaj li ib lab cov khoom xa tawm xyoo dhau los.
Q: Yav dhau los, thaum lub sij hawm cov khoom tsis txaus, peb tau pom qhov nce ntawm cov khoom cuav los tsoo lub khw. Rochester tau ua dab tsi los hais txog qhov no?
A: Cov saw hlau muaj kev xav tau nce ntxiv thiab kev txwv tsis pub xa khoom; Tag nrho cov lag luam lag luam tau cuam tshuam, nrog qee cov neeg siv khoom tau ntsib kev nyuaj siab los muab thiab siv rau kev lag luam grey lossis cov neeg muag khoom tsis raug cai. Kev lag luam khoom cuav yog qhov loj thiab lawv raug muag los ntawm cov khw muag khoom grey no thiab nws thiaj li nkag mus rau cov neeg siv khoom kawg. Thaum lub sij hawm ntawm qhov tseem ceeb thiab cov khoom tsis muaj, qhov kev pheej hmoo ntawm cov neeg siv khoom kawg los ua tus neeg raug tsim txom ntawm cov khoom cuav yog ntau ntxiv. Yog, nws muaj peev xwm los xyuas kom meej qhov tseeb ntawm cov khoom los ntawm kev sim thiab tshuaj xyuas, tab sis qhov no yog lub sij hawm siv thiab kim, thiab qee zaum, qhov tseeb tseem tsis tau lees paub tag nrho.
Tib txoj hauv kev kom paub tseeb tias qhov tseeb yog yuav los ntawm ib tus neeg muag khoom tso cai los xyuas kom meej cov pedigree ntawm cov khoom. Cov neeg lag luam tso cai zoo li peb muab kev pheej hmoo tsis muaj peev xwm thiab yog tib txoj kev nyab xeeb tiag tiag los ua kom peb cov neeg siv khoom cov kab ntau lawm khiav thaum muaj kev tsis txaus, kev faib tawm thiab cov khoom lag luam tawm.
Txawm hais tias tsis muaj leej twg nyiam raug nyiag los ntawm cov khoom cuav, hauv ntiaj teb ntawm cov khoom thiab cov khoom, cov txiaj ntsig ntawm kev yuav khoom cuav tuaj yeem ua rau muaj kev puas tsuaj. Nws tsis yooj yim xav txog kev lag luam dav hlau, foob pob hluav taws lossis cov cuab yeej kho mob cawm txoj sia nrog cov khoom tseem ceeb uas yog cuav thiab ua haujlwm tsis zoo ntawm qhov chaw, tab sis cov no yog cov ceg txheem ntseeg, thiab cov ceg txheem ntseeg siab. Kev yuav los ntawm ib tus neeg muag khoom tso cai uas ua haujlwm nrog cov khoom lag luam tseem ceeb tshem tawm cov kev pheej hmoo no. Cov neeg muag khoom xws li Rochester Electronics muaj 100% kev tso cai, qhia tias lawv tau ua raws li SAE aviation standard AS6496.
Cias muab tso, lawv tau tso cai los ntawm cov thawj cov khoom tsim los muab cov khoom traceable thiab guaranteed yam tsis tas yuav tsum tau kuaj zoo los yog kev ntseeg siab vim hais tias cov khoom yog los ntawm cov thawj cov khoom tsim.
Q: Dab tsi tshwj xeeb cov khoom lag luam cuam tshuam los ntawm qhov tsis txaus?
A: Ob pawg feem ntau cuam tshuam los ntawm cov saw hlau tsis txaus yog cov khoom siv dav dav (ntau-channel) thiab cov khoom lag luam uas muaj tsawg dua lwm txoj hauv kev. Xws li lub zog tswj chips thiab cov khoom siv hluav taws xob sib cais. Feem ntau, cov khoom no los ntawm ntau qhov chaw lossis muaj kev sib raug zoo ntawm cov neeg muag khoom sib txawv. Txawm li cas los xij, vim lawv tau siv dav hauv ntau daim ntawv thov thiab ntau qhov kev lag luam, cov khoom xav tau tau siab, cov neeg muag khoom nyuaj kom ua raws li qhov xav tau.
MCU thiab MPU cov khoom lag luam tseem tab tom ntsib cov kev sib tw ntawm cov saw hlau, tab sis rau lwm qhov laj thawj. Ob pawg no ntsib teeb meem tsim nrog ob peb txoj hauv kev, thiab cov neeg muag khoom tau ntsib nrog cov khoom sib txawv ua ke los tsim. Cov khoom siv no feem ntau yog ua raws li cov tub ntxhais CPU tshwj xeeb, kev nco qab, thiab cov txheej txheem ntawm cov khoom siv peripheral, thiab cov khoom ntim tshwj xeeb, nrog rau cov software hauv qab thiab cov lej, tuaj yeem cuam tshuam rau kev xa khoom. Feem ntau, qhov kev xaiv zoo tshaj plaws rau cov neeg siv khoom yog rau cov khoom lag luam nyob hauv tib qho ntau. Tab sis peb tau pom ntau qhov xwm txheej hnyav uas cov neeg siv khoom tau teeb tsa cov rooj sib tham kom haum cov pob khoom sib txawv txhawm rau ua kom cov kab ntau lawm khiav.
Q: Koj xav li cas txog kev lag luam tam sim no thaum peb mus rau xyoo 2022?
A: Kev lag luam semiconductor tuaj yeem raug hu ua kev lag luam cyclical. Txij li thaum pib ntawm Rochester Electronics hauv 1981, peb tau muaj kwv yees li 19 lub voj voog kev lag luam ntawm ntau qib. Cov laj thawj sib txawv rau txhua lub voj voog. Lawv yuav luag ib txwm pib dheev thiab tom qab ntawd nres tam sim ntawd. Qhov sib txawv tseem ceeb nrog lub voj voog kev ua lag luam tam sim no yog tias nws tsis tau teeb tsa tawm tsam qhov cuam tshuam ntawm kev lag luam thoob ntiaj teb booming. Qhov tseeb, ntawm qhov tsis sib xws, kev kwv yees qhov tshwm sim hauv peb ib puag ncig tam sim no yog qhov nyuaj dua.
Puas yog nws yuav xaus sai sai no, ua raws li cov khoom lag luam overhang uas peb feem ntau pom, sib piv rau kev xav tau kev lag luam tsis muaj zog, ua rau kev lag luam poob qis? Los yog nws puas yuav ncua thiab ntxiv los ntawm cov kev xav tau muaj zog raws li kev lag luam thoob ntiaj teb rov qab los tom qab kis thoob qhov txhia chaw?
2021 yuav yog xyoo tsis tau muaj dua los rau kev lag luam semiconductor. World Semiconductor Trade Statistics tau kwv yees tias kev lag luam semiconductor yuav loj hlob los ntawm 25.6 feem pua hauv 2021, thiab nws cia siab tias kev lag luam yuav loj hlob ntxiv los ntawm 8.8 feem pua hauv 2022. Qhov no tau ua rau cov khoom tsis txaus hauv ntau qhov kev lag luam. Xyoo no, Rochester Electronics txuas ntxiv nqis peev los txhim kho nws cov peev txheej tsim khoom siv hluav taws xob, tshwj xeeb hauv thaj chaw xws li 12-nti nti ua thiab ntim khoom thiab sib dhos.
Saib tom ntej, peb ntseeg tias cov khoom siv hluav taws xob hauv tsheb yuav dhau los ua ib feem tseem ceeb ntawm Rochester lub tswv yim, thiab peb tau ntxiv dag zog rau peb cov kev tswj xyuas kom zoo txhawm rau ua kom peb txoj kev mob siab rau muab peb cov neeg siv khoom nrog cov qauv siab tshaj plaws ntawm cov khoom thiab kev pabcuam.
