Hauv no nyeem, Kuv yuav taug kev koj los ntawm tus txheej txheem ntawm tsim tus PCB kev teeb tsa thiab tau txais nws luam tawm los ntawm ib lub chaw tsim qauv PCB. Kev ua haujlwm ntawm koj qhov Circuit Court yuav nyob ntawm seb qhov nws tau nce tawm ntawm PCB, yog li kuv yuav muab ntau lub tswv yim seb yuav ua li cas rau koj txoj kev tsim kho.
Koj tuaj yeem yuav tsum tau PCBs hauv tsev nrog ib tus cess uas zoo li tsim cov luam tawm los ntawm cov duab thaij duab. Tab sis cov txujci no ntxhov heev thiab nws siv ntau cov tshuaj. Nws yooj yim dua (thiab pheej yig) kom tau txais koj tus PCB los ntawm lub chaw tsim khoom. Yuav ua kom pom txoj kev, Kuv yuav siv qhov kev pab online hu ua EasyEDA los tsim ib qhov PCB kev teeb tsa rau lub LM386 suab amplifier, ces kuv yuav muaj nws ua thiab qhia koj cov ntsiab lus. Cov dawb hauv online tsim software yog ib qho yooj yim mus siv thiab cov nqi yog pheej yig heev.
NWS TAG NRHO STARTS NROG TSIS TXAUS SIAB
Ua ntej koj pib tsim koj tus PCB, nws yog ib lub tswv yim zoo uas ua rau koj lub voj voog. Cov tswv yim yuav ua hauj lwm ua ib qho qauv rau kev tso tawm cov khoom siv thiab muab cov khoom hauv PCB. Ntxiv rau, PCB editing software tuaj yeem hloov tag nrho cov khoom, cov ntawv, thiab xov hlau rau hauv PCB cov ntaub ntawv, uas yuav ua rau tus txheej txheem tsim tau yooj yim dua (ntxiv rau qhov no tom qab).NeoDen muab tag nrho cov smt kev sib txuas daws teeb meem, xws li SMT reflow qhov cub, yoj tes laug tshuab, de laim cov tshuab luam ntawv, PCB loader, PCB unloader, nti mounter, SMT AOI tshuab, SMT SPI tshuab, SMT X-hluav taws xob tshuab, SMT los ua ke kab khoom siv, PCB Cov Khoom Pab Khoom Siv Nruab Nruag SMT tej yam zoo li txhua yam SMT cov cav koj xav tau, thov hu rau peb kom paub ntxiv:
YUAV UA LI CAS THIAJ PAUB NTXIV
Ua ntej koj pib, koj yuav xav tau ib lub tswv yim ntawm ntau npaum li cas tso zis fais fab koj xav tau los ntawm tus neeg hais tau lus. Koj yuav tsum paub txog lub impedance ntawm koj tham thiab qhov input voltage ntawm koj lub suab qhov. Nco ntsoov xyuas lub TDA2050's datasheet kom pom qhov kev siab tshaj plaws rau cov kev tsis sib haum no, thiab tsim koj tus amp nyob hauv kev nyab xeeb ntawm kev khiav hauj lwm.
Raws li tus datasheet, TDA2050 tau tso tawm 28 Watts rau 4 Ω tham nrog 0.5% distortion ntawm 22 V zog mov. Kuv 'dhau yuav ua tau 6 Ω hais lus nrog kuv tus neeg hais lus, kuv thiaj li mus tsom rau 25 Watts tso zis hluav taws xob. Kuv mam li yuav siv ib lub iPhone raws li lub suab qhov twg, uas muaj ib tug 1 V tawm voltage.
