Nezve iyo yekuchengetedza musimboti wePCB wedunhu mabhodhi, iyo otomatiki solder muchina inopa nyore kune soldering yePCB redunhu mabhodhi, asi matambudziko anowanzoitika mukugadzirwa kwePCB edunhu mabhodhi, izvo zvinokanganisa kunaka kwekutengesa.Kuti uvandudze maitiro ekuyedza, kumwe kugadziridzwa kwehunyanzvi kunofanirwa kuitwa pabhodhi rakagadziridzwa pamberi peiyo online inoshanda bvunzo yePCB redunhu bhodhi kuti kuderedze pesvedzero yekukanganisa kwakasiyana pakuita bvunzo.Iwo chaiwo matanho ndeaya anotevera:
.Kugadzirira kusati kwaedzwa
Short-circuit the crystal oscillator (teerera kune mana-pini crystal oscillator kuti uone kuti ndeapi mapini maviri ari mapini ekubuda kwechiratidzo uye anogona kupfupisa mapini maviri aya. haifanirwe kunge ipfupi-inotenderera !!) Kune yakakura-yakawanda kugona electrolytic Iyo capacitor inofanirawo kutengeswa pasi kuti ivhure.Nekuti kuchaja uye kuburitswa kwemahombe-capacitors anokonzeresa kukanganisa.
2. Shandisa nzira yekubvisa kuyedza PCB redunhu bhodhi remudziyo
Munguva yekuyedzwa kwepamhepo kana kuyedza kwekuenzanisa kwechishandiso, ndapota simbisa zvakananga mhedzisiro uye rekodha mudziyo wapfuura bvunzo (kana kuti zvakajairika).Kana iyo bvunzo ikakundikana (kana isisina kushivirira), inogona kuongororwa zvakare.Kana ichiri kutadza, unogona zvakare kusimbisa mhinduro dzebvunzo kutanga.Izvi zvinoenderera kusvika mudziyo uri pabhodhi waedzwa (kana kuenzaniswa).Wobva wabata neaya maturusi anotadza bvunzo (kana ari kunze kwekushivirira).
Zvimwe zviridzwa zvekuyedza zvinopawo yakaderera asi yakanyatso shanda nzira yekugadzirisa yemidziyo isingakwanise kupasa bvunzo yepamhepo yebasa: nekuti magetsi echiridzwa chekuyedza kubhodhi redunhu anogona zvakare kuiswa kune inoenderana magetsi uye rinoenderana simba. kuwanikwa kwemudziyo kuburikidza neklipu yekuedza.Kana pini yemagetsi yechigadzirwa ichicheka papini yepasi, chigadziro chichabviswa kubva pamagetsi ekugadzirisa magetsi ebhodhi redunhu.
Panguva ino, ita online inoshanda bvunzo pane mudziyo;sezvo mamwe maturusi ari paPCB asingazopihwe simba rekushanda kuti abvise kukanganisa, iwo chaiwo bvunzo maitiro panguva ino ichave yakaenzana ne "quasi-offline test".Chiyero chekururama chichave chakanyanya kukwirira.Kuvandudza kukuru.
