SCM system luam tawm tswv yim tsim tawm tswv yim tsim tawm
Peb yog ib lub tuam txhab luam ntawv loj hauv Shenzhen Tuam Tshoj. Peb muaj cov phau ntawv luam tawm, phau ntawv xov xwm luam ntawv, phau ntawv luam ntawv, phau ntawv nyuaj, phau ntawv luam tawm, phau ntawv luam tawm, phau ntawv luam tawm, lub thawv ntim, daim qhia ntawv, txhua yam ntawm PVC, cov ntawv luam tawm, ntawv sau cia, hom tshwj xeeb ntawv xim luam tawm khoom, kev ua si cardand li ntawd.

Tus qauv tsim ntawm pawg thawj coj saib kev sib txuas lus yog ib qho tseem ceeb rau kev cuam tshuam ntawm ib qho-nti system. Tsim cov ntawv luam tawm ntu thiab thaiv raws li peb lub hauv paus ntawm kev tswj cov suab nrov kom ntau li ntau tau, txo cov suab nrov thiab kev sib txuas, thiab txo cov suab nrov.
Lub rooj sibtham luam tawm yuav tsum muab faib kom zoo. Ib qho-tus ntiv tes tuaj yeem muab faib rau peb thaj chaw, uas yog qhov chaw analog (ntshai kev cuam tshuam), digital tsam (piv txwv, cuam tshuam thiab cuam tshuam) thiab lub zog tsav cheeb tsam (cuam tshuam qhov chaw).
Daim phiaj xwm Circuit Court Circuit Court tau txais kev pab los ntawm ib qho chaw taw tes rau lub zog thiab ib qho taw qhia dav dav. Lub hwj chim thiab hauv av ntawm peb cheeb tsam raug coj tawm hauv peb txoj kev. Cov suab paj nruag yog nyob deb ntawm lub suab tsis yog suab.
Tsim cov kev txawj ntse
1. Npib lub voj oscillating Circuit Court thiab qhov tshwj xeeb high-speed logic Circuit Court mus rau hauv av thiaj li hais tias ib puag ncig hluav taws yog ze rau xoom.
2. Qhov cuab yeej I / O tsav tsheb thiab lub hwjchim muaj zog yog ze li sai tau rau sab ntawm lub rooj tsavxwm, ze rau lub connector.
3. Siv cov cuab yeej qes tsawg yam tsis muaj cov cuab yeej siv high-speed, high-speed devices tsuas yog siv cov chaw tseem ceeb.
4. Siv lub moos uas ua tau raws li qhov tsawg zaus uas yuav tsum tau ua los ntawm lub system. Lub moos generator yog ze li sai tau rau lub tshuab uas siv lub moos. Lub quartz crystal oscillator case yuav tsum tau muab tso rau hauv, thiab txoj kab ntawv yuav tsum ntev li sai tau, thiab yuav tsum tsis txhob raug nplua txhua qhov chaw. Hauv qab quartz oscillator, thaj chaw hauv qab no cov cuab yeej suab nrov heev yuav tsum tau ua kom loj dua thiab cov kab hluav taws xob yuav tsum tsis txhob raug. Txoj kab moos yog ib qho rau kab I / O thiab muaj tsawg cuam tshuam dua li cov kab Ii / parallel parallel. Txoj kab xuaj moos yog deb ntawm I / O kab.
5. Siv txoj kab ntawv 45-degree thiab tsis siv 90-degree khoob khoob kom txo tau cov pa tawm ntawm kev tawm dag zog. Vaj huam sib luag tawm, ob chav vaj huam sib luag, fais fab qaum thiab av hlau yuav tsum yog tuab li tau. Cov xov tooj ntawm cov kab xev tshaj yuav tsum tsawg tshaj plaws li.
6. 4 txheej txheem board yog 20dB qis dua ob tog vaj huam sib luag. Lub rooj 6-txheej txheem yog 10 dB qis tshaj li 4-txheej txheem board. Sim siv cov laug cam sab nraud thaum kev lag luam tso cai.
7. Cov kab tseem ceeb yuav tsum yog luv li sai li sai tau thiab kom tuab li sai tau, nrog kev tiv thaiv ntawm ob sab. Yog hais tias lub teeb liab thiab lub suab nrov band teeb liab raug coj tawm los ntawm kab xev xaim. Nws yuav tsum muab rho tawm los ntawm hauv av-teeb liab-hauv av.
8. Tsis txhob tsim ib lub voj ntawm txhua kab teeb meem. Yog tias nws tsis muaj kev tiv thaiv, lub voj yuav tsum yog me me li qhov ua tau.
9. Rau hom A / D hom, qhov digital thiab cov qhov analog yog zoo dua mus ncig thiab tsis txhob hla. Cov hlua ntawm lub suab nrov nrov yuav tsum tsis txhob ua kom tig mus rau cov kab kev kub ceev thiab cov kab ua kom siab
10. Lub tshuab hluav taws xob ib leeg ib qho thiab lwm yam IC circuits. Yog tias muaj ntau yam khoom siv hluav taws xob thiab ntau thaj av, ntxiv ib lub qhov ntim ntawm lub zauv rau txhua qhov kawg. Ntxiv ib lub decacpling capacitor rau txhua tus IC, thiab xaiv lub monolithic los yog ceramic capacitor nrog lub teeb liab siab li lub decoupling capacitor. Thaum twg lub qhov daus loj ntawm lub decoupling yog siv rau lub rooj tsavxwm, lub koob yuav tsum yog luv li sai tau. Ib lub peev xwm loj tantalum los yog siv lub tshuab hluav taws xob polyester tsis yog siv lub tshuab ua hluav taws xob (electrolytic capacitor) ua ib tug cia lub cev rau lub voj voog vim tias cov electrolytic capacitor muaj ib qhov chaw loj loj thiab muaj kev cuam tshuam rau cov neeg siab heev. Yog siv cov electrolytic capacitors, lawv yuav tsum tau sib xyaws nrog cov decoupling capacitors nrog cov yam ntxwv zoo siab.
11. Qhov chaw nres nkoj I / O uas tsis siv los ntawm MCU yuav tsum yog txhais tau tias yog qhov kev tso tawm. Pib ntsais koj teeb ntawm thaj chaw nrov nrov yog lim. Ib qho diode tawm yuav tsum tau tso rau sab nraum lub chaw tso tsheb. Ib txoj hlua ntawm qhov khoom tuaj yeem siv tau los kho qhov ntug ntawm I / O kab lossis muab qee qhov dej tshuaj.
12. Thaum xav tau, kev siv lub tshuab ua rau lub cev muaj zog ntawm lub cev muaj zog ua rau fibite muaj peev xwm ntxiv rau lub hwj chim thiab kab hauv av kom thaiv tau cov kis ntawm cov suab nrov nrov. Tsis muaj teebmeem hauv cov kabmob uas tsis muaj kabmob, cov high-zaus, high-power lead-out cables yuav tsum tau shielded. Cov hlau lead hlau thiab cov xaim hluav taws xob hauv av yuav tsum tau sib ntswg.
13. Cov ntawv luam tawm Circuit Court Circuit yog loj los yog cov teeb meem ntawm cov teeb liab dhau heev lawm, yog li qhov ncua sij hawm rau ntawm kab ntawv ntau dua los yog sib npaug ntawm lub teeb meem nce ntxiv. Cov kab no ua tiav raws li txoj kab sib kis, thiab qhov kev sib txuas ntawm lub davhlau ya nyob twg ntxiv.
14. Tsis txhob siv lub qhov khoos kas IC, khi rau IC cia kom ncaj qha rau, thiab tus IC nrog tuav lub peev xwm loj heev.
