Niki Gucukura inyuma PCB?
Inzira yo gucukura inyuma ya PCB, nanone yitwa kugenzura gucukumbura ubujyakuzimu, ikubiyemo gukuramo stub muri PCB nyinshi kugirango ikore vias. Intego yo gucukura inyuma ni ukorohereza urujya n'uruza rw'ibimenyetso hagati yuburyo butandukanye bwubuyobozi nta nkomyi bivuye ku biti udashaka.
Kugirango utange ibisobanuro byumvikana kubikorwa byo gucukura inyuma, reka dusuzume urugero.
Dufate ko hariho ibice 12 bya PCB hamwe nu mwobo uhuza ibice bya mbere na 12. Ikigamijwe ni uguhuza gusa icyiciro cya mbere gusa murwego rwa 9, mugihe ugumya 10 kugeza kumurongo wa 12. Nyamara, ibice bidafitanye isano birema "stubs" zishobora kubangamira inzira yikimenyetso, bikavamo ibibazo byubusugire bwibimenyetso. Gucukura inyuma bikubiyemo gusiba ibyo biti bivuye kuruhande rwibibaho kugirango tunoze ibimenyetso.
Intego yo gucukura inyuma ya PCB niyihe?
Gucukura inyuma ya PCB bikoreshwa mugukuraho igice kidakoreshwa cya plaque unyuze mu mwobo (unyuze) urenze urwego rwa nyuma rwa PCB. Iyi nzira ifasha kugabanya ibibazo byubusugire bwibimenyetso, nka stub resonance hamwe nibimenyetso byerekana, bishobora kugaragara muburyo bwihuse bwibishushanyo mbonera.
“Ikigereranyo cya aspect” ni iki?
Ibibazo bijyanye nimbaho zumuzingo zacapwe ›TERMINOLOGY
Isano iri hagati ya diameter yumwobo nuburebure bwayo. Iyo uruganda ruvuze ko umusaruro wabo ufite "aspect aspect" ya 8: 1 bivuze, kurugero, ko umwobo wa diameter ari mm 0,20 muri mm 1,60 mm PCB.
Kubintu bya HDI, igipimo cya microvia kigarukira kuri 1: 1, ariko 0.7-0.8: 1 nibyiza koroshya isahani.
Ni izihe nyungu zo gucukura inyuma PCB?
Ibyiza byo gucukura inyuma ya PCB harimo kunonosora ibimenyetso byerekana ibimenyetso, kugabanya igihombo cyo kwinjiza, kongera imiyoboro nyabagendwa, no kongera umurongo. Mugukuraho igice kidakoreshwa cyanyuze kuri barriel, gucukura inyuma bigabanya stub resonance hamwe nibimenyetso byerekana, bikavamo isuku kandi yukuri yohereza ibimenyetso.
