Muri PCB ishushanya, imiterere igira uruhare runini kandi rwinshi muri plegning yose hamwe nibisabwa. Buri ntambwe yo gushushanya ikeneye kwitabwaho no gutekereza ku mikorere myiza.
Iburyo-inguni nyinshi ni ibintu bigomba kwirindwa byinshi bishoboka muri WCB, kandi hafi kuba imwe mubipimo byo gupima ireme ryinshi. None ni izihe ngaruka zingahe-inguni insinga zifite ibizamini?
Icya kabiri, ibiciro bitandukanye biterwa nibikorwa bitandukanye.
Ibintu bitandukanye byumusaruro bivamo ibiciro bitandukanye. Nka kibaho cyashyizwe ahagaragara na tin-tin-tin, imiterere ya routing no gukubita, gukoresha imirongo ya ecran ya silk hamwe n'imirongo ya firime yumye izakora ibiciro bitandukanye, bikaviramo bitandukanye.
Ihame, inguni-inguni zimfuruka zizahindura umubiri wumurongo wohereza, bikavamo guhagarika umutima. Mubyukuri, ntabwo ari ibintu byiza gusa, ahubwo nanone ibimenyetso bikarishye bishobora gutera impinduka.
Ingaruka zimfuruka iburyo zigaragazwa cyane mubimenyetso bitatu: Ubwa mbere, mfuruka irashobora kuba ihwanye numutwaro wagutse kumurongo wohereza kumurongo, gahoro gahoro; Icya kabiri, kutabuza kutabuza bizatera kwerekana ibimenyetso;
Iya gatatu ni EMI yakozwe ninsanganyamatsiko iburyo. Ubushobozi bwa parasitike bwatewe n'inguni iburyo
W bivuga ubugari bwa trace (igice: Inch), εr yerekeza ku ndyo ihoraho, kandi Z0 nizo zibangamira umurongo woherejwe.
Nkumurongo wimiterere yuburenganzira-inguni yiyongera, imfashanyo hazagabanuka, bityo rero ibintu bimwe byerekana ibimenyetso bizabaho. Turashobora kubara impetane ihwanye nyuma yubugari bwumurongo bwiyongereye ukurikije formulation yo kubara itazwi mu gice cyo kohereza.
Noneho kubara ibikorwa byo kwerekana ukurikije formulaire ya expique: ρ = (zs-z0) / (zs + z0). Mubisanzwe, impinduka zibangamira iburyo-angle wiring iri hagati ya 7% na 20%, bityo rero ibikorwa byinshi byerekana ni 0.1. Shenzhen Anke PCB Co, ltd
