Kuzindikira Kwambiri ndi Njira Zakuyendera PCB: Onani, mverani, kununkhiza, kukhudza ...

1. Ndi zoletsedwa kugwiritsa ntchito zida zoyeserera zoyeserera kuti mugwire TV yamoyo, Audio, video ndi zida zina zam'madzi zapansi pa PCB popanda kusinthira

Ndi zoletsedwa kuyesa mwachindunji TV, Audio, kanema ndi zida zina popanda kusinthika kwamphamvu ndi zida ndi zida zokhala ndi zipolopolo. Ngakhale wolemba foni wamba ndi Cassette ali ndi mphamvu yosinthira mphamvu, mukamalumikizana ndi zida zapadera za TV kapena zomveka bwino.

2. Yang'anirani magwiridwe antchito a chitsulo chogulitsira poyesa ma pCB board

Saloledwa kugwiritsa ntchito chitsulo chogulitsa ndi mphamvu. Onetsetsani kuti chitsulo chogulitsidwa sichinanenedwe. Ndikofunika kuyika chipolopolo cha chitsulo chogulitsa. Samalani mosamala ndi Chressity. Ndiko kukhala otetezeka kugwiritsa ntchito mankhwala otsika a magetsi a 6 ~ 8v.

3. Dziwani mfundo zogwirira ntchito zophatikizira ndi mabwalo okhudzana ndi masitepe a PCB

Asanayang'anire ndi kukonza zomwe zikuphatikizidwa, muyenera kudziwa bwino ntchito ya dissii yomwe imagwiritsidwa ntchito, magetsi a magetsi, ndi magetsi wamba, ndi mfundo yogwiritsira ntchito madera omwe ali ndi zigawo zokhumudwitsa. Ngati mikhalidwe yomwe ili pamwambapa yakumana, kusanthula ndi kuyendera kumakhala kosavuta.

4. Osayambitsa mabwalo afupiafupi pakati pa zikhomo poyesa PCB

Mukayeta magetsi kapena kuyesa funde ndi proberi ya oscillososcope ya oscilloscoscope, osayambitsa dera pakati pa zikhomo zophatikizira chifukwa cha mayeso omwe amatsogolera kapena kukayika. Ndikofunika kuyeza pa zotumphukira zosindikizidwa zolumikizidwa mwachindunji ndi zikhomo. Madera aliwonse ochepa omwe amatha kuwononga mosavuta, choncho samalani pang'ono poyesa ma cmos ophatikizira.

5. Kukana kwamkati kwa chipangizo cha PCB Board kuyenera kukhala lalikulu

Tikayeza magetsi a DC zikhomo za iC iC, zolimba ndi kukana mkati mwa 20k / v kuyenera kugwiritsidwa ntchito, apo ayi pakhale cholakwika chachikulu cha zikhomo.

6. Yang'anirani kusamalira kutentha kwa madera ophatikizira mukamayesa mabodi a PCB

Madera omwe adaphatikizira kuyenera kusintha kutentha, ndipo saloledwa kugwira ntchito pansi pa mphamvu yopanda kutentha.

7. Waya wotsogola wa PCB Board ayenera kukhala oganiza bwino

Ngati mukufuna kuwonjezera zinthu zakunja kuti musinthe gawo lowonongeka, zigawo zing'onozing'ono ziyenera kugwiritsidwa ntchito, ndipo zingwe ziyenera kukhala zomveka zopewa kuphatikizira kwa madipouni ndi kutha kwa madera osakhalitsa.

8. Onani bolodi ya PCB kuti muwonetsetse bwino

Wogulitsa, wogulitsayo ndi wolimba, ndipo kudziunjikira kwa msirikali ndi ma pore akhoza kuyambitsa msinkhu wabodza. Nthawi yogulitsa nthawi zambiri imaposa masekondi atatu, ndipo mphamvu ya chitsulo iyenera kukhala pafupifupi 25 yotentha. Madera omwe adaphatikizidwa omwe adagulitsidwa ayenera kuyesedwa mosamala. Ndikofunika kugwiritsa ntchito mawu okwana mawu kuti muyeze kalitsidwe pakati pa zikhomo, onetsetsani kuti palibe msilikali, kenako tembenuzani mphamvu.
9. Osazindikira mosavuta kuwonongeka kwa dera lophatikizidwa poyesa bolodi ya PCB

Osaweruza kuti dera lophatikizidwa lawonongeka mosavuta. Chifukwa choti madera ambiri omwe aphatikizidwa amaphatikizidwa mwachindunji, nthawi yomweyo dera likasintha, ndipo zosinthazi sizingoyambitsa chifukwa chowonongeka kwa gawo lomwe laphatikizidwa. Kuphatikiza apo, nthawi zina, magetsi oyesedwa ndi pini iliyonse ndi osiyana ndi nthawi yomwe imagwirizana kapena pafupi, silingatanthauze nthawi zonse. Chifukwa zolakwa zofewa sizingasinthe kusintha kwa DC Vorusege.

Njira ya PCB Board

Kwa pcb yatsopano yomwe yangobwezeredwa kumene, tiyenera kuona ngati pali zovuta pa bolodi, monga kuti ndizofunikira, mabwalo otseguka, malo otseguka ndi okulirapo.

Kwa bolodi yopanga madera atsopano, kusinthana nthawi zambiri kumakumana ndi zovuta zina, makamaka ngati bolodi ikakhala yayikulu ndipo pali zigawo zambiri, nthawi zambiri zimakhala zosatheka kuyamba. Koma ngati mungatchule njira zomveka zobwezera, kusintha komwe kumapangitsa kawiri zotsatira ndi theka la khama.

PCB Board Debopsing Njira:

1. Kwa pcb yatsopano yomwe yangobwezeretsedwa, tiyenera kuwona ngati pali zovuta pa bolodi, monga ngati kuli koyenera, mabwalo otseguka, ndi nthaka yokwanira.

2. Kenako zigawozo zaikidwa. Ma module odziyimira pawokha, ngati simukutsimikiza kuti amagwira ntchito moyenera, ndibwino kuti musayikenso onse, koma kukhazikitsa zonse, mutha kuziyika zonse nthawi imodzi), kotero kuti ndikosavuta kudziwa mtundu wonse). Mukakumana ndi mavuto, simungathe kuyamba.

Nthawi zambiri mutha kukhazikitsa magetsi koyamba, kenako mphamvu pakuwona ngati mphamvu yamagetsi yotulutsa ndizabwinobwino. Ngati simukhala ndi chidaliro chochuluka mukamatha (ngakhale mutakhala otsimikiza, tikulimbikitsidwa kuti muwonjezere fuse, tingoganizirani za mphamvu zoyendetsedwa ndi mphamvu zoyendetsedwa ndi zomwe sizingatheke.

Imbani kuteteza kwambiri poyamba, kenako pang'onopang'ono kuwonjezera mtengo wamagetsi wa magetsi owongoleredwa, ndikuwunikira zomwe zalembedwapo, zolowetsa magetsi, zolowetsa magetsi komanso kutulutsa magetsi. Ngati palibe chitetezo chopitilira muyeso komanso mavuto ena pakusintha kwakukulu, ndipo magetsi otulutsa afika bwino, magetsi ali bwino. Kupanda kutero, pezani mphamvu zophera, pezani cholakwika, ndipo bwerezani zomwe zili pamwambapa mpaka magetsi ali bwinobwino.

3. Kenako, ikani ma module ena pang'onopang'ono. Nthawi iliyonse gawo la gawo laikidwa, mphamvu pakuyesera ndikuyesa. Mukamaumba, tsatirani njira zomwe zili pamwambazi kuti mupewe kwambiri chifukwa cha zolakwa ndi / kapena zolakwa za kuyika ndikuwotcha zigawo.
