Packaging muchina wakabatanidzwa wedunhu kuyedzwa, chikuru chinofanira kunge chiri kuyera akakosha bvunzo mapoinzi.
Yese nzira ndeye kushandisa chiridzwa chekuyedza tsoka yega yega voltage uye pini kune pasi kuramba, yekupinza uye kubuda voltage, mashandisiro emagetsi uye yekuisa / kubuda waveform, uye mhedzisiro yebvunzo inosiyana neyakajairika yakabatanidzwa yedunhu paramita, inogona kutonga iyo yakabatanidzwa yedunhu kuti iedzwe. normal.
mu
kurongedza muchina, iyo inowanzo shandiswa yakasanganiswa yedunhu microprocessors, gobvu firimu rakasanganiswa redunhu uye chinja simba rekushandisa rinoshanda amplifier IC.
Ngationgororei zvakadzama pamusoro peizvi.
kurongedza muchina yakasanganiswa yedunhu kuyedzwa mukiyi yeiyo yakabatanidzwa yedunhu test point.
1.
Kiyi kune microprocessor yakabatanidzwa yedunhu test point
kiyi yeiyo microprocessor yakabatanidzwa yedunhu bvunzo poindi inonyanya kuve VDD simba rekupa divi, RESET, RESET, crystal IN vibration chiratidzo chekuisa, Xor crystal vibration chiratidzo chinobuda kuguma kwekupinza, kubuda, uye mamwe maseketi.
online bvunzo kuyera kiyi poindi yekupokana uye voltage kukosha uye yakajairwa inogona kutonga iyo yakabatanidzwa dunhu yakajairika;
2.
Kiyi yekuchinja kwesimba rekupa IC test point
kiyi yekuchinjisa magetsi ekupa IC bvunzo poindi inonyanya kuve Vc yekuona yekuisa yekupedzisira, voltage, ikozvino yekuona yekupinda, pulse kubuda, nezvimwe.
bvunzo yepamhepo yakashandiswa kuyera iyo yakabatanidzwa yedunhu voltage uye kuramba kwepini yega yega, uyezve ichienzaniswa nedata pane yakajairwa, senge mutsauko mukuru, inofanirwa kunge iri kuyedza ine chekuita nechikamu, chikamu chinotemerwa pasi pemamiriro ezvakajairwa, chinogona kutonga Integrated circuit yakakuvadzwa.
Muchinjiko yakabatanidzwa yedunhu chinja chubhu ndiyo yakakosha chikamu, iyo yakavakirwa-mukati gobvu firimu yakabatanidzwa redunhu remagetsi hombe chinja chubhu kana zvisina kunaka kukahadzika chinja chubhu inogona kuyerwa nekuchinja chubhu c, b, e zvakanyanya pakati pemberi uye reverse kuramba. kumutongo.
3.
Kiyi yekushanda amplifier IC test point
kiyi yeanoshanda amplifier IC bvunzo poindi inonyanya kupinza uye kubuda.
Iyi poindi ye static voltage value yakakwira.
bvunzo, iyo multimeter kune dc voltage, kuyera iyo inobuda voltage kukosha pakati pekupedzisira uye isina kunaka magetsi ekupedzisira.
Neruoko rwesimbi tweezers, zvakare, kubata iyo miviri yekuisa yekupedzisira yeanoshanda amplifier (
Joinha chiratidzo chejamming)
, uye tarisa wachi oscillation mamiriro, yakajairika, multimeter pointer ichave yakakura oscillation, senge pointer isingafambi, ipapo iyo inoshanda amplifier yakakuvadzwa.
4.
Yemagetsi bhasikoro chaiyo yakabatanidzwa yedunhu point test.
mumuchina wekurongedza, iyo inowanzoshandiswa 555 nguva base yakasanganiswa yedunhu TL494 dunhu uye dunhu.
Ngatinyatso tarisai mapoinzi akakosha edzimwe nzira dzekuyedza (
1)
Kutsunga kwedunhu rakasanganiswa T494
kurongedza muchina wakabatanidzwa wedunhu kuyedzwa kweiyo yakasanganiswa yedunhu T494 mumatanho anotevera.
1)
Gadzirira chiridzwa.
Kuedzwa kwemasekete akabatanidzwa kusarudza mamwe mabasa, akadai sedhijitari multimeter, modhi ine MY68 inoshanda mhando uye MS820 mhando yedhijitari multimeter.
vanogona kuona kuwanda kwe150 KHZ uye 200 KHZ.
Uyewo unoda oscilloscope, inogadziriswa yekudzivirira waya inotenderera, nezvimwe.
2)
Oscillation frequency kuyerwa.
Chekutanga screw multimeter kusvika 200 KHZ, preliminary ongororo T494 oscillation rate (
Pane imwe dunhu rakasanganiswa senge pazasi 200 hz, inogona kugadzirisa giya)
, kuitira kuti zvive zvakarurama.
T494 oscillation muna 5, uye 6 tsoka, saka multimeter zvinyoreso uye mumakumbo maviri aya, vanogona kuona masaha wave.
Charger uye control circuit ye oscillation frequency ye20 ~ 80 kh, mhedzisiro yekutsunga ndeyehumwe kukosha, iyo yakabatanidzwa yedunhu oscillation yakajairika, kushomeka capacitance kukosha kwakarurama.
kana pasina zviratidzo zve oscillation, tarisa nzvimbo yekusangana nemapeni uye, wiring, nezvimwe.
Kana retest ichiri shoma pane kuyerwa kwenhamba yedunhu rakasanganiswa rine dambudziko.
kana iyo frequency isingabvumirwe, kuudza iyo Rr kana Cr, yekuona mamiriro akakodzera kugadzirisa kana kutsiva.
3)
Kuyera reshiyo yebasa.
Yakagadzirira kuoscilloscope, ichaita T494 inobuda pini 9, 10, batanidza iyo yekupinda interface yeoscillograph, uye tungamira kune iyo 9, gumi tsoka uye yakayerwa mutoro.
Pano zvakakosha kuziva kuti hapana chiyero chemutoro, chiyero chebasa hachina chiyero chakarurama, chinotsauka kubva pakukosha kwekugadzirwa kwepakutanga.
Tarisa oscilloscope 9, 10 tsoka dzekubuda waveform, panguva imwechete gadzirisa reshiyo yebasa: kudzora chinhu, gadzirisa kumhanya unodzora mubato, ne0 spin;
Iyo charger, gadzirisa kukosha kwekupokana kubva ku0 kusvika ku6 tsoka (
Iyo capacitance C, panguva imwe chete gadzirisa)
.
Panguva ino kubva oscilloscope vanofanira kuona basa reshiyo kuchinja kubva zero kusvika zana muzana renji.
kurongedza muchina wakabatanidzwa wedunhu zvakajairika kana kwete zvine hukama nemuchina unogona kushanda zvakajairika, saka zvakakosha, ndinovimba chinyorwa ichi chekurongedza muchina wakabatanidzwa wedunhu bvunzo chinobatsira kwauri.
Pese mubvunzo wekuyera muchina unosimudzwa, mumwe anouya nezwi rokuti ''.
