HV9910 Universal LED tsav nrog 220v AC input

Kauj ruam 1: Taw qhia

Ceev faj: Kev tsim kho daim ntawv no ntawm cov khoom siv hluav taws xob tau pom zoo tsuas yog rau cov neeg uas tau ntsib lossis muaj peev xwm tuav tau lub zog AC. Yog li tsis txhob sim qhov Circuit Court no yog tias koj tsis tau ntsib dua hauv kev ua haujlwm siab Voltages.

Kev saib xyuas zoo yuav tsum tau ua thaum kuaj lub zog fais fab. Tsis txhob kov ntawm ib qho ntsiab lus hauv PCB vim tias qee cov ntsiab lus yog qhov tseem ceeb. Txawm tias tom qab hloov lub Circuit Court, tsis txhob kov cov ntsiab lus nyob ib ncig ntawm lub capacitor loj los tiv thaiv hluav taws xob. Kev saib xyuas hnyav yuav tsum tau ua los tsim lub Circuit Court kom tsis txhob muaj hluav taws xob luv thiab hluav taws.

HV9910 yog tus tsav tsheb thoob ntiaj teb siv rau tsav txoj hlua (s) ntawm LEDs los ntawm ntau yam kev siv hluav taws xob (8v txog 450v DC). Muab qhov tam sim no tsis tu ncua ntawm cov zis rau kev tsav tsheb sib txawv ntawm cov hlua LED (s). Kuv tau txais kev pab ntawm cov ntaub ntawv ntawm HV9910, cov ntaub ntawv ntawm demo board 2 (cov ntawv txuas nrog) ntawm HV9910 thiab Daim Ntawv Thov Nco tseg AN-H48.

Muaj ntau cov ntaub ntawv muaj nyob hauv cov kab ntawv hais saum toj no thiab cov ntaub ntawv hais txog HV9910.

Kuv tau ua qhov Circuit no los ntawm kev siv cov txiaj ntsig sib txawv ntawm cov khoom siv (Saib daim ntawv Excel txuas) los muab qhov tso tawm ntawm 35 txog 40 volts DC thiab 1 Amp tam sim no.

Ib qho ntxiv qhov sib txawv hauv txoj haujlwm no yog kev siv ob tus inductors hauv kab ntawv kom tau txais cov khoom tsim tawm vim tias kuv tsis tuaj yeem nrhiav pom ib qho inductor ntawm qhov xav tau tus nqi los ntawm kuv cov khoom lag luam hluav taws xob hauv zos. Rau lub hom phiaj no kuv tau txais kev pab los ntawm kws tshaj lij fab haujlwm los ntawm Supertex thiab tau ua tiav hauv kev siv ob lub inductors zoo ib yam ntawm tus nqi hauv ib qho kom tau txais cov zis xav tau.

Hauv qhov haujlwm no kuv tau ua PCB rau HV9910 los ntawm kos kom txog thaum kawg.

Tsis tas li kuv tau txuas Eagle PCB cad software schematic thiab board cov ntaub ntawv siv rau cov khoom tso rau thiab ua ib qho kev hloov kho uas xav tau los ntawm ib tus neeg siv.

Raws li HV9910 yog lub ntsej muag teeb tsa IC yog li nws tau muab tso rau sab hauv qab ntawm PCB ib sab ntawm lwm cov khoom siv.

Kauj Ruam 2: Yam Yuav Tsum Tau

Nram qab no yog cov npe ntawm cov khoom uas xav tau los ua qhov haujlwm no.

Ferric Chloride rau PCB Etching (Thov siv hnab looj tes roj hmab los lis cov tshuaj no)

Daim Ntawv Xuab Zeb Zoo

Me rab riam ntse los yog hniav

Ib lub tshuab PCB me me rau qhov tho qhov hauv PCB thiab laum cov khoom sib txawv raws li PCB qhov ntau thiab tsawg (.75 mm txog 1.5 mm)

Ib qho Hlau rau cov txheej txheem hloov pauv rau PCB

Kauj Ruam 3: Cia Peb Ua PCB Kauj Ruam 1

Koj xav tau luam tawm ntawm lub rooj tsavxwm los ntawm kev siv EAGLE software lossis koj tuaj yeem siv cov ntawv PDF txuas rau luam tawm. Nco ntsoov tias koj tau luam tawm tsuas yog ntawm lub tshuab luam ntawv laser luam ntawv thiab inkjet tshuab luam ntawv yuav tsis ua haujlwm. Vim tias peb yuav siv cov txheej txheem hloov pauv toner los ua PCB. Hauv txoj kev no tsuas yog luam ntawv laser ua haujlwm.

Koj kuj xav tau daim ntawv tooj liab los ua PCB. Siv cov ntawv xuab zeb zoo heev los txhuam kom huv thiab ntxuav daim ntawv tooj liab ua ntej yuav hloov cov toner.

Muab cov ntawv luam tawm ntawm lub rooj tsavxwm rau ntawm daim ntawv tooj liab.

Muab cov hlau kub heev (Hlau yuav tsum nyob rau qhov chaw kub heev) ntawm nws vim tias tsis txhob txav cov ntawv luam tawm ntawm daim ntawv tooj liab. Hlau yuav tsum nyob rau qhov chaw kub heev lwm qhov ntse lub toner ntawm daim ntawv yuav tsis lo rau daim ntawv tooj liab.

Tsiv cov hlau ntawm daim ntawv ntug mus rau ntug rau ntawm xaum 3 rau 4 feeb. Koj yuav pom tias daim ntawv yuav lo rau ntawm daim ntawv tooj liab. Nco ntsoov tias txhua daim ntawv lo ntawm daim ntawv tooj liab.

Thaum koj paub tseeb tias daim ntawv tau ua tiav ntawm daim ntawv tooj liab tshem cov hlau thiab cia daim ntawv tooj liab txias rau ob peb feeb.

Kauj Ruam 4: PCB KAUJ RUAM 2

Tam sim no peb yuav tsum tshem daim ntawv los ntawm daim ntawv tooj liab. Qhov no coj lub khob me me ntawm cov dej sov thiab muab PCB tso rau hauv yam tsawg 30 feeb. Los ntawm kev ua qhov no peb yuav tshem daim ntawv thiab lub toner yuav nyob ntawm daim ntawv. Txhawm rau tshem daim ntawv so cov ntawv ntub nrog koj cov ntiv tes. Koj tuaj yeem siv txhuam txhuam hniav kom maj mam tshem daim ntawv. (Nws ua haujlwm zoo).

Ua ntej muab PCB los rau hauv kev daws teeb meem thov txheeb xyuas qhov cim tseg kev saib xyuas tag nrho cov kab thiab cov chaw tau ua tiav lwm qhov kev paub siv tus cim me me mus tas li txhawm rau kho qhov zoo ntawm koj li PCB.

Kauj Ruam 5: PCB KAUJ RUAM 3

Tam sim no noj peb lub tais diav ntawm ferric chloride thiab ntxiv rau hauv ib khob dej. Koj tuaj yeem ua qhov kev daws teeb meem ntau npaum li koj xav tau. Siv hnab looj tes roj hmab thaum tuav cov tshuaj no. Ua ntej muab PCB los rau hauv kev daws teeb meem thov txheeb xyuas qhov cim tseg kev saib xyuas tag nrho cov kab ua tiav lwm qhov kev paub siv tus cim me me mus tas li txhawm rau kho qhov zoo ntawm koj li PCB.

Muab PCB rau hauv Ferric Chloride tov. Yog tias koj siv cov dej sov me ntsis cov txheej txheem ua haujlwm yuav ua haujlwm nrawm thiab nws yuav siv sijhawm tsawg dua yuav yog 5 txog 7 feeb.. Khaws txav lub thawv (tsis faib nws) kom txog thaum PCB ua kom tag. Ntxuav PCB nrog cov kais dej kom huv. Saib cov duab.

Kauj Ruam 6: PCB KAUJ RUAM 4

Siv rab riam me me los yog rab riam ntse los yog cov ntawv xuab zeb tshem tawm tsuas yog cov toner los ntawm PCB. Tom qab ntawd siv cov ntawv xuab zeb zoo heev los ntxuav PCB.

Yog tias koj xav kom muaj kev nyab xeeb ntawm cov tooj liab los ntawm kev xeb ces koj tuaj yeem tso ib txheej txheej tshuaj tiv thaiv ntawm PCB.

Kauj Ruam 7: Muab Cheebtsam ntawm PCB (Sib dhos)

Siv cov duab muab tso ua ke txhawm rau txhawm rau ntxiv cov khoom ntawm PCB. Saib xyuas kom zoo thaum siv lub tshuab IC HV9910. muaj lub voj voos me me sau rau ntawm nws qhov no yog tus pin 1 ntawm HV9910.

AC input 90 txog 265 volts

Tawm tso tawm 30 txog 40 volts DC 1 Amp.
