Izindleko ze-PCB Nge-intshi Eyisikwele: Yini Eqhuba Intengo ye-PCB nokuthi Ungayehlisa Kanjani

"Izindleko nge-intshi yesikwele" yinani labathengi abazama ukulinganisa intengo ye-PCB - kodwa impendulo eqotho ukuthi indawo ingenye yezici eziningi, futhi ibhodi elincane, eliyinkimbinkimbi lingabiza kakhulu nge-intshi yesikwele kunebhodi elikhulu, elilula. Ukuqonda ukuthi yini ngempela eqhuba intengo kukuvumela ukuthi uklame izindleko futhi uthole izingcaphuno ezinembile. Lo mhlahlandlela uchaza ukuthi yini enquma izindleko ze-PCB, ukuthi kungani izibalo nge-intshi yesikwele zidukisa, ukuthi intengo ye-prototype kanye nevolumu ihluke kanjani, ukuthi unganciphisa kanjani izindleko, nokuthi izingcaphuno ze-Highleap Electronics zicacile kanjani.

1. Yini enquma izindleko ze-PCB?

Izindleko ze-PCB zinqunywa usayizi webhodi, inani lezendlalelo, izinto zokwakha, isisindo sethusi, usayizi omncane womkhondo/isikhala kanye nosayizi wembobo, ukuqeda kwendawo, izici ezikhethekile, kanye — ngaphezu kwakho konke — nobuningi. Akukho noyedwa obeka intengo; ziyahlangana, futhi ushintsho kunoma yikuphi lungashukumisa izindleko kakhulu. Izinto eziyinhloko ezibangela lokhu:

Ubuningi buyisici esikhulu ngoba izindleko eziningi ze-PCB ziwukusethwa okuzinzile — amathuluzi, amafilimu, kanye nokulungiswa kwamaphaneli — okusabalala kulo lonke i-oda. Izici ezifanayo ziyavela noma nini lapho ubheka izindleko zebhodi lesekhethi elenziwe ngokwezifiso , futhi izakhiwo eziyinkimbinkimbi ezifana ne-HDI zine-premium yazo, njengoba kubonakala ezindlekweni ze-HDI PCB . Amanani ezinto nawo ahambisana nemakethe, kufaka phakathi amanani ethusi.

2. Kungani "izindleko nge-intshi yesikwele" zingakukhohlisa

Izindleko nge-intshi yesikwele ziyadukisa ngoba zibamba indawo kuphela ngenkathi zinganaki inani lezingqimba, ubunzima bezici, izinto zokwakha, ukuqeda, kanye nobuningi — ngakho ibhodi elincane, eliminyene, elinezingqimba eziningi lingabiza kakhulu nge-intshi yesikwele kunebhodi elikhulu, elilula elinezingqimba ezimbili. Amabhodi amabili endawo efanayo angaba namanani ahlukene kakhulu, okusho ukuthi inombolo eyodwa nge-intshi yesikwele ayikwazi ukusetshenziswa kumiklamo ehlukene.

I-metric iphinde ifihle umphumela wezindleko ezihleliwe: ngoba ukusetha kusatshalaliswe phezu kwephaneli kanye nokuhleleka, izindleko ze-intshi ngayinye yesikwele zokusetshenziswa kweprototype encane ziphakeme kakhulu kunebhodi elifanayo ngobuningi, yize ukwakheka kungashintshiwe.
