Pochita ndi PCB msonkhano, chovuta kwambiri kulosera ndi kuthetsa ndi vuto la magetsi dera lalifupi.Makamaka pamene bolodi ndi zovuta ndi zigawo zosiyanasiyana dera akuwonjezeka, mphamvu kotunga yochepa dera vuto laMsonkhano wa PCBndizovuta kuzilamulira.
Njira yowunikira kutentha
KusanthulaMawu Oyamba:
1. Nthawi zambiri, ngati bolodi silili lofupikitsidwa ndi malata, mwachitsanzo, chip chathyoka kapena capacitor yasweka, kukana GND nthawi zambiri si 0Ω, mochuluka kapena mocheperapo, padzakhala ochepa Ω kapena magawo khumi. mwa Ω.Pogwiritsa ntchito izi, mutha kupeza mwachangu.
2. Gwiritsani ntchito magetsi oyendetsedwa mwachindunji.Sinthani mphamvu yamagetsi kuti ikhale voteji yamagetsi afupikitsa (3.3V short-circuit to 3.3V).Khazikitsani kumayendedwe aposachedwa, malire apano amatha kukhazikitsidwa ku 500mA, kutengera momwe zinthu ziliri.
3. Chotsani magetsi aPulogalamu ya PCB, gwirizanitsani ndi magetsi oyikidwa, ndikuwona kumene bolodi la dera likutentha, ndipo kumene kuli kotentha nthawi zambiri kumakhala dera lalifupi.
4. Kuti muwone komwe kuli kutentha, mutha kugwiritsa ntchito chithunzithunzi cha infrared thermal kuti muwone.Ngati mulibe chojambula cha infrared thermal, mutha kuchigwira mwachindunji ndi manja anu ndikuchimva (samalani kuti musadziwotche.
Kusamalitsa:
Kuyika malire apano a gwero lachindunji pakali pano kuyenera kutsimikiziridwa molingana ndi momwe zinthu zilili.Ngati malire omwe alipo panopa ndi ochepa kwambiri, kutentha sikudzakhala koonekeratu, ndipo palibe vuto lomwe lingapezeke.Ngati malire apano ndi akulu kwambiri, mawaya amkuwa pa PCB akhoza kuwotchedwa.Mutha kusintha pang'onopang'ono kuchokera ku zazing'ono kupita zazikulu mpaka mutadziwa komwe kuli vuto.
M'mawu amodzi, Pochotsa gawo lalifupi lamagetsi a msonkhano wa PCB, tiyenera kusamala kuti tipeze ndikuthetsa vutoli moyenera.
PCBFuture ikhoza kuyamba pakusindikizidwa dera bolodi kupanga, kudzera ku zigawo zoperekera ndi kusonkhanitsa.Ndife okondwa kupereka matabwa ndi zigawo.Pambuyo kupanga anamaliza, tikhoza kupereka akatswiri PCB anayendera kuonetsetsa khalidwe la PCB.Kuti mudziwe zambiri, chonde imelo kuservice@pcbfuture.com.
