2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:28

ABSTRATH Txoj Haujlwm no los ntawm qhov xav tau kom tau txais lub tshuab hluav taws xob yoj hluav taws xob nrog bandwidth ntau dua 10 Mhz thiab kev cuam tshuam sib txawv hauv qab 1%, txhua qhov no nrog tus nqi qis. Daim ntawv no piav qhia tus qauv tsim ntawm lub tshuab hluav taws xob yoj hluav taws xob nrog bandwidth ntau dua 10MHz, uas tsim tawm: sine, daim duab peb sab, sawtooth, lossis xwmfab (mem tes) waveforms nrog kev cuam tshuam tsis sib xws hauv qab 1%, hloov pauv lub luag haujlwm, hloov pauv zaus, tso tawm TTL thiab offset qhov hluav taws xob Nws kuj tseem nthuav qhia kev tsim qauv ntawm lub txee zaus.

Kauj Ruam 1: Daim Ntawv Teev Npe

Nov yog cov npe tseem ceeb. Qhov tseem ceeb, MAX 038 yog qhov tsis siv, tab sis nws tseem tuaj yeem yuav. Nws tau txuas nrog cov peev txheej kwv yees.

Kauj Ruam 2: PCB Ua

Npaj Npaj PCB rau kab lus. Nws yog ob lub ntsej muag PCB. Cov txheej txheem xaiv yog tshuaj lom neeg, yog li thawj qhov peb yuav tsum tau ua yog cov txheej txheem ntawm txheej txheej nrog lub tshuab laser, thiab tom qab txheej txheem tshuaj lom neeg. Ua ntej tshaj plaws, peb pib nrog kev teeb tsa hauv-j.webp

Kauj Ruam 3: PCB Ua (Serigraph)

Serigraph. Lub laser.machine yuav tshem cov xim hauv qhov chaw uas nws tsim nyog tias cov kua qaub tawm tsam. Lub tshuab laser tsis rau cov txheej txheem no yog: Ceev 60. Hwj chim 30. Cov ntsiab lus daws teeb meem 1200, kev xav Raster. Peb yuav tsum ua cov txheej txheem ob zaug hauv ob sab ntawm PCB, txhawm rau tshem cov xim kom raug.

Kauj Ruam 4: PCB Ua (pleev xim tshem tawm)

Tshem cov xim tawm. Tom qab cov txheej txheem dhau los, tseem tshuav cov xim thiab lawv yuav tsum raug tshem tawm ua ntej cov txheej txheem kua qaub, tab sis tom qab tshem tawm PCB los ntawm lub tshuab laser peb yuav tsum tau tos tsawg kawg ib teev thiaj li yuav qhuav. Rau lub hom phiaj no peb siv cov tshuaj hnyav xws li turpentine lossis cov khoom hloov pauv. Thaum peb tau ntxuav PCB, nws yuav tsum tshwm zoo li ib ntawm daim duab

Kauj Ruam 5: PCB Ua (Acid Attack)

Acid nres Rau txheej txheem no peb xav tau cov kua qaub thiab lwm yam khoom txhawm rau pib ua cov tshuaj tiv thaiv thiab ua cov txheej txheem sai dua. Qhov tsim nyog rau txheej txheem no tuaj yeem yuav hauv khw hluav taws xob. Feem ntau, siv cov kua qaub yog hydrochloric acid ntxiv rau dej, muag hauv cov khw muag khoom zoo li cov khoom huv (cov kua qaub). Loj dua qhov ua kom nrawm dua yuav yog txheej txheem. Sib nrug los ntawm cov kua qaub peb xav tau, raws li peb tau hais ua ntej, cov khoom lag luam nrawm. Qhov zoo tshaj plaws yog sodium perborate muag hauv cov khw muag khoom siv hluav taws xob thiab hauv cov khw muag khoom zoo li cov khoom lag luam kom cov khaub ncaws dawb (tsawg kawg hauv Spain), lwm yam khoom yog dej oxygen, tab sis nws xav tau qib siab.

Ua ntej tshaj plaws peb yuav tsum tau laum PCB thiab peb pib ua kom cov khoom sib xyaw. Peb yuav tsum tau them sai sai rau qhov tseeb tias nws yog ob lub ntsej muag PCB, yog li nws muaj vias los txuas ob sab thiab feem ntau ntawm cov khoom siv tau muab muag los ntawm ob sab hauv Circuit Court no. Peb tuaj yeem pom qhov no hauv cov duab. Kev hloov chaw ntawm cov khoom nws zoo li cov duab qhia. Cov resistors ntawm 100K, nti 1 (ua haujlwm lub zog ua haujlwm), cov khoom siv cuam tshuam nrog rau cov nti 1 thiab lub zog ntawm 220K, suav nrog kev hloov pauv ntawm lub luag haujlwm, muaj txiaj ntsig tsuas yog ua rau nthwv dej. Lub voj voog no tuaj yeem tsim qee qhov kev sib txawv, rau qhov nws feem ntau txav mus rau hauv av los ntawm kev hloov SW3. (Hom hloov ON-ON). Yog tias peb tsis siv qhov no peb tuaj yeem tshem tawm nws, nco ntsoov txuas nws rau hauv av.

Lub capacitor ntawm 1uF tsis yog polarized, (saib Circuit piav qhia 3.2.1). Qhov txuas ntawm qhov xaiv ntau yog txuas nrog kev hloov pauv, uas tus pin ntawm tus txuas txuas rau tus tiv thaiv 4K7 txuas nrog rau tus pin nquag (A) ntawm qhov hloov. Qhov kev hloov pauv no tau teeb tsa rau plaub qhov hloov pauv, tawm ib qho dawb (xaiv ntau zaus, 27pF). Raws li nws tau hais tawm hauv kev piav qhia hauv Circuit, qhov muaj peev xwm tiv thaiv kab mob tuaj yeem txwv qhov bandwidth. Hauv qhov kev tsim qauv no muaj peev xwm tiv thaiv kab mob vim kev siv cov transistors mus rau kev hloov pauv ntawm lub capacitors, yog li qhov siab tshaj plaws tau mus txog yog 10MHz, tab sis yog tias peb xav kom dhau qhov txwv no nws tsuas yog tsim nyog los txiav tawm 27pF lub tshuab hluav taws xob lossis siv me me. tau txais bandwidth ntau dua 20MHz. Lwm qhov txuas yog ntaus hom kev xaiv waveform. Peb yuav tsum teeb tsa qhov hloov mus rau 3 hloov 5V tus pin txuas nrog rau tus lej sib txuas ntawm qhov hloov pauv (A) thiab A0 thiab A1 rau tus pin 1 thiab 2, tawm hauv tus pin 3 dawb. MAX038 yog cov khoom tsis suav nrog, tab sis nws muaj peev xwm yuav nws. Nws tsis pom zoo yuav nws hauv Suav teb vim tias txawm tias nws pheej yig dua nws tsis ua haujlwm.

BNC txuas yog rau TTL cov zis. Cov choj p1 thiab p2 hloov 47 ohms resistors, vim tias BNC txuas tau muaj qhov kev tiv thaiv no. Tus pin zoo ntawm cov electrolytic capacitor tau txuas nrog hauv cov hneev taw ob npaug. Lawv tau muab tso raws li daim duab. Lub potentiometer ntawm 1K yog rau kev tswj cov qib tso zis ntawm cov duab yoj. Lub hwj chim xiav ntawm 4k7 tswj hwm qhov nce, txhawm rau xaiv qib tso zis ntau.

Kauj ruam 11: Waveform Generator Sib Sau Ua Ke. 4

Qhov hloov SW5 commutes qhov offset voltage rau Zero. Potentiometer 4K7 yog siv los hloov qhov ntsuas hluav taws xob. Tus choj p3 thiab lub qhov uas nyob saum toj thiab lub tshuab ua haujlwm ua haujlwm zoo ib yam li cov neeg siv hauv Circuit Court, txhawm rau xa lub teeb liab mus rau lub tswb zaus.

Cheebtsam tau muab tso zoo li peb tuaj yeem pom hauv daim duab.

Kauj Ruam 16: Cov Khoom Siv Hluav Taws Xob Sib Sau 3

Cov xov hlau tsis cim npe muab qhov hluav taws xob rau lub diode coj, txhawm rau paub thaum twg lub tshuab hluav taws xob tau qhib.

Kauj Ruam 17: Lub Thawv Qauv

Tus qauv yog ua los ntawm plywood daim ntoo ntawm 5mm. Kev tsim qauv tau ua nrog qhov kev pab cuam Rhinoceros los ntawm Zoe Carbajo. Nws yog nruab nrab nrog lub tshuab laser. Nws yog qhov tsim nyog los ntxiv kev zam rau hauv kev tsim, txhawm rau ua kom qhov sib txawv sib koom ua ke tau zoo. Nws yuav nyob ntawm cov khoom siv. Nws tau txuas nrog ib daim ntawv nplaum txhuas ntawv (feem ntau yog siv hauv cov kav dej) txhawm rau txhawm rau txuas rau hauv av, qhov chaw nws yog xim hlau ntawm lub zog thiab cov hloov pauv. Cov av tau koom nrog cov ntawv txhuas los ntawm FM input BNC txuas.

Nws tau txuas nrog ib daim ntawv nplaum txhuas ntawv (feem ntau yog siv hauv cov kav dej) txhawm rau txhawm rau txuas rau hauv av, qhov chaw nws yog xim hlau ntawm lub zog thiab cov hloov pauv. Cov av tau koom nrog cov ntawv txhuas los ntawm FM input BNC txuas.

Kauj Ruam 19: PCB thiab Cov Qauv Txheej Txheem 2

Hauv qab no peb tuaj yeem pom qhov chaw ntawm tus hloov pauv, txuas rau cov xaim hluav taws xob thiab hloov pauv. Ob yam khoom kawg no tau txais los ntawm lub hwj chim ntawm lub khoos phis tawj. Ob tus pin ntawm 0V los ntawm qib thib ob ntawm kev hloov pauv, yuav tsum tau koom nrog, vim tias peb cov khoom xav tau lub zog nruab nrab taw tes. Cov no txuas nrog hauv av (tus pin nruab nrab ntawm qhov txuas) Cov av ntawm cov xaim hluav taws xob yuav tsum txuas nrog rau hauv av ntawm lub zog siv ib yam
