Kurushanwa PCB

Kuva mu kinyejana cya 20 kugeza mu ntangiriro z'ikinyejana cya 21, inganda zikoresha ibikoresho bya elegitoroniki zigenda zitera imbere mu buryo bwihuse bw'ikoranabuhanga, ikoranabuhanga rya elegitoronike ryateye imbere vuba.Nkinganda zacapwe zumuzunguruko, gusa hamwe niterambere ryayo, zishobora guhora zihagije kubakiriya.Hamwe nubunini buto, bworoshye kandi buto bwibicuruzwa bya elegitoronike, icyapa cyumuzingo cyacapye cyateje imbere ikibaho cyoroshye, ikibaho cyoroshye, ikibaho cyiziritse gihumeka.

Muganira kubyerekeye imyobo ihumye / yashyinguwe, dutangirana na gakondo nyinshi.Imiterere isanzwe yumurongo wumurongo wububiko igizwe numuzenguruko wimbere hamwe nizunguruka ryimbere, kandi inzira yo gucukura no guhinduranya ibyuma mumwobo ikoreshwa kugirango igere kumikorere yo guhuza imbere muri buri ruziga.Ariko, kubera kwiyongera k'umurongo, uburyo bwo gupakira ibice burahora buvugururwa.Kugirango utume akarere k'umuzunguruko kagarukira kandi twemere ibice byinshi kandi byisumbuyeho, hiyongereyeho ubugari bwumurongo woroshye, aperture yagabanutse kuva kuri mm 1 ya DIP jack aperture igera kuri 0,6 mm ya SMD, hanyuma igabanuka kugeza kuri munsi 0.4mm.Ariko, ubuso buzakomeza gutwarwa, bityo hashyizweho umwobo hamwe 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 ugahuza imbere mu kibaho.

Ibyiza byo guhuma no gushyingurwa ikibaho:

Muri tekinoroji idasobekeranye, gukoresha umwobo uhumye hamwe nu mwobo washyinguwe birashobora kugabanya cyane ubunini bwa PCB, kugabanya umubare wabyo, 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 nanone bitera inzitizi zikomeye kumashanyarazi yimbere yimbere ya PCB nyinshi.Ibi binyujijwe mu myobo bifata umwanya ukenewe mu nsinga, kandi bikanyura hejuru yubuso bwamashanyarazi hamwe nubutaka bwinsinga, bizasenya ibintu biranga inzitizi zumuriro wubutaka kandi bigatera kunanirwa kwinsinga zubutaka. urwego.Kandi gucukura bisanzwe bisanzwe bizikuba inshuro 20 gukoresha ikoreshwa rya tekinoroji idatobora.
