Copper coating, kureva, nzvimbo isina basa paPCB inoshandiswa seyero yepasi, uye yobva yazadzwa nemhangura yakasimba, idzi nzvimbo dzemhangura dzinonziwo kuzadza mhangura. Kukosha kwemhangura yemhangura ndeyekudzikisa pasi impedance uye kuvandudza anti-kupindira kugona. Deredza kudonha kwemagetsi, kuvandudza simba remagetsi; Yakabatanidzwa netambo yepasi, iyo loop nzvimbo inogonawo kuderedzwa. Zvakare nechinangwa chekugadzira PCB welding zvakanyanya sezvinobvira pasina deformation, vazhinji vanogadzira PCB vanozodawo kuti PCB vagadziri vazadze nzvimbo yakavhurika yePCB nemhangura kana grid-yakafanana newaya yepasi, kana mhangura ikabatwa zvisina kunaka, hazvizoiti. kurasika, ingava mhangura “yakanaka pane yakaipa” kana kuti “yakaipa pane yakanaka”?
Isu tese tinoziva kuti mune yakakwira frequency, iyo yakagovaniswa capacitance ye wiring pane yakadhindwa redunhu bhodhi ichashanda, kana kureba kwakakura kupfuura 1/20 yeinoenderana wavelength yeruzha frequency, pachava neantenna mhedzisiro, uye ruzha ruchaburitswa kunze kuburikidza newaya, kana paine yakashata yakadzikwa yemhangura yemhangura muPCB, iyo copper yemhangura yave chishandiso chekuparadzira ruzha, saka, mune yakakwira frequency circuit, Usafunga kuti imwe nzvimbo iyo tambo yepasi yakabatanidzwa pasi, iyo "yepasi wire", uye inofanira kunge iri pasi pe λ/20 spacing, punching makomba mu wiring, uye pasi ndege ye multilayer board "yakanyatsogadziriswa". Kana chifukidzo chemhangura chakanyatsogadziriswa, chifukidzo chemhangura hachingowedzera ikozvino, asiwo chinotamba basa reviri rekudzivirira kupindira.
Pane kazhinji nzira mbiri dzakakosha dzekupfekedzwa kwemhangura, ndiko kuti, nzvimbo yakakura yemhangura uye grid yemhangura, uye inowanzo bvunzwa kana nzvimbo yakakura yemhangura kana grid copper yakanaka, hazvina kunaka kuita generalization. Nei zvakadaro? Yakakura-nzvimbo yemhangura yemhangura ine basa rehuviri rekuwedzera ikozvino uye kudzivirira, asi yakakura-nzvimbo yemhangura yakavharidzirwa, kana inopfuura wave soldering, bhodhi rinogona kukwidibira kumusoro, uye kunyange furo. Naizvozvo, nzvimbo yakakura yemhangura yekuputira, kazhinji inovhura akati wandei slots, kuderedza mhangura foil kupupa, nyore grid copper coating inonyanya kudzivirira mhedzisiro, kuwedzera basa remazuva ano rakaderedzwa, kubva pakuona kwekupisa kupisa, grid ine zvakanakira. (inoderedza kupisa kwemhangura) uye yakaita rimwe basa mukudzivirira kwemagetsi.
Asi zvinofanirwa kutaurwa kuti grid inoumbwa neyakadzama nzira yemutsara, tinoziva kuti kudunhu, hupamhi hwemutsara weiyo dhizaini bhodhi inoshanda frequency ndiyo inowirirana "yemagetsi kureba" (saizi chaiyo yakakamurwa ne kushanda frequency yeinoenderana dhijitari frequency inogona kuwanikwa, kunyanya ona mabhuku akakodzera), kana iyo frequency yekushanda isiri yakanyanya kukwirira, Zvichida basa remitsara yegidhi harina kunyatsojeka, kana kureba kwemagetsi uye kushanda frequency match, yakashata kwazvo, uchaona kuti dunhu harishande nemazvo, kwese kuri kuburitsa zvikwangwani zvinokanganisa basa rehurongwa. Saka kune vaunoshanda navo vanoshandisa grid, zano rangu nderokusarudza maererano nekugadzirwa kwebhodhi redunhu, uye kwete kubatirira pane chimwe chinhu. Naizvozvo, iyo yakakwira frequency yedunhu inopesana nekukanganisa zvinodiwa zve-multi-chinangwa grid, yakaderera frequency reketi ine yakakwira yazvino dunhu uye imwe inowanzoshandiswa yakazara mhangura paving.
