Ihiganwa rya PCB

Kuva mu kinyejana cya 20 kugeza mu ntangiriro z'ikinyejana cya 21, inganda zikoresha ibikoresho bya elegitoroniki zikoresha amashanyarazi mu gihe cyihuta cy’iterambere ry’ikoranabuhanga, ikoranabuhanga rya elegitoronike ryateye imbere vuba. Nka bicapiro byumuzunguruko wacapwe, gusa hamwe niterambere ryayo, birashobora guhora byujuje ibyifuzo byabakiriya. Hamwe nubunini buto, bworoshye kandi buto bwibicuruzwa bya elegitoronike, icyapa cyumuzunguruko cyacapwe cyateje imbere ikibaho cyoroshye, ikibaho cyoroshye, ikibaho cyiziritse gihumye cyumuzingi nibindi.

Muganira kubyerekeye imyobo ihumye / yashyinguwe, dutangirana na gakondo nyinshi. Imiterere isanzwe yinzira yumuzunguruko igizwe numuzenguruko wimbere nu muzunguruko wo hanze, kandi inzira yo gucukura no guhinduranya ibyuma mumwobo ikoreshwa kugirango igere kumikorere yo guhuza imbere muri buri cyiciro cyizunguruka. Ariko, kubera ubwiyongere bwumurongo, uburyo bwo gupakira ibice burahora buvugururwa. Kugirango uhindure akarere k'umuzunguruko kugarukira no kwemerera ibice byinshi kandi byisumbuyeho, usibye ubugari bwumurongo woroshye, aperture yagabanutse kuva kuri mm 1 ya DIP jack aperture igera kuri 0,6 mm ya SMD, kandi iragabanuka kugeza munsi ya 0.4mm. Nyamara, ubuso buzakomeza gutwarwa, bityo umwobo ushyinguwe nu mwobo uhumye. Igisobanuro cyumwobo washyinguwe nu mwobo uhumye nuburyo bukurikira:

Umwobo waguzwe:

Binyuze mu mwobo uri hagati yimbere, nyuma yo gukanda, ntibishobora kuboneka, ntabwo rero bigomba gufata umwanya winyuma, impande zo hejuru nu hepfo yumwobo ziri murwego rwimbere rwibibaho, mu yandi magambo, yashyinguwe muri ikibaho

Umwobo uhumye:

Byakoreshejwe muburyo bwo guhuza hagati yubuso bumwe cyangwa byinshi imbere. Uruhande rumwe rw'umwobo ruri ku ruhande rumwe rw'urubaho, hanyuma umwobo ugahuzwa n'imbere mu kibaho.

Ibyiza by'impumyi ihumye kandi yashyinguwe:

Mu buhanga budasobekeranye, gukoresha umwobo uhumye nu mwobo ushyinguwe birashobora kugabanya cyane ubunini bwa PCB, kugabanya umubare w’ibice, kunoza imikoreshereze ya electromagnetique, kongera ibiranga ibicuruzwa bya elegitoroniki, kugabanya ibiciro, ndetse no gukora igishushanyo kora byoroshye kandi byihuse. Muburyo bwa PCB bwo gutunganya no gutunganya, binyuze mu mwobo birashobora gutera ibibazo byinshi. Ubwa mbere, bafite umwanya munini wumwanya mwiza. Icya kabiri, umubare munini unyuze mu mwobo ahantu hacucitse nawo utera inzitizi zikomeye kumashanyarazi yimbere yimbere ya PCB nyinshi. Ibi binyujijwe mu myobo bifata umwanya ukenewe mu nsinga, kandi bikanyura cyane hejuru yumuriro wamashanyarazi hamwe nubutaka bwinsinga zubutaka, bizasenya ibiranga inzitizi yibiranga amashanyarazi yubutaka kandi bigatera kunanirwa kwinsinga zubutaka urwego. Ubucukuzi busanzwe bwa mashini buzaba bwikubye inshuro 20 gukoresha ikoreshwa rya tekinoroji idasobekeranye.
