Enqubweni yokukhiqiza i-PCB, siyacasulwa ukuthi siphakanyiswe i-Palize PCB njengomzila wethebhu ukuze ubhekane namabhodi ethu emaphethelweni.lapha sizokunikeza isingeniso esiningiliziwe senqubo yethebhu -umzila.
Kuyini umzila wethebhu?
Umzila wamathebhu kuyindlela edumile yephaneli ye-PCB esebenzisa amathebhu anezimbobo noma ezingenawo.Uma uhlukanisa ama-PCB anephaneli ngesandla, kufanele usebenzise uhlobo olunembobo.Uma unomuzwa wokuthi ukwephula i-PCB ephanelini kungabangela ukucindezeleka okukhulu ku-PCB, kuwukuhlakanipha ukusebenzisa ithuluzi elikhethekile elizovimbela ukulimala kwebhodi.
Lapho ibhodi linesimo esingavamile, noma ibhodi lidinga unqenqema olucacile bese iphaneli lidinga ukuqondiswa ithebhu.Umdwebo 8 ubonisa umdwebo wephaneli yethebhu -umzila, Umdwebo 9 isithombe sephaneli yomzila wethebhu.Kuphaneli yomzila wethebhu ukuze kuphulwe ibhodi kuphaneli ngemva kokuhlanganisa, amaphuzu ka-V noma "izimbobo zokuluma igundane" zingasetshenziswa.Izimbobo zokuluma amagundane umugqa wemigodi usebenza ngendlela efanayo nezimbobo ezimpahleni zezitembu.Kodwa khumbula ukuthi amaphuzu we-V azonikeza umkhawulo ocacile ngemuva kokuthi amabhodi ehlukanisiwe namaphaneli, "izimbobo zokuluma igundane" ngeke zinikeze umkhawulo ocacile.
Kungani sidinga ukubeka amabhodi njenge-tad-routing?
Enye yezinzuzo zomzila wamathebhu ukuthi ungakwazi ukukhiqiza amabhodi angewona ama-rectangular.Ngokuphambene, ububi bomzila wamathebhu ukuthi kudinga impahla yebhodi eyengeziwe, engakhuphula izindleko zakho.Kungase futhi kubeke ingcindezi eyengeziwe ebhodini eduze kwethebhu.Ukuze uvimbele ukucindezelwa kwebhodi, gwema ukubeka izingxenye ze-PCB eduze kwamathebhu.Nakuba lingekho izinga elithile lokubeka izingxenye eduze kwamathebhu, ngokuvamile, i-100 mils iyibanga elijwayelekile.Ngaphezu kwalokho, kungase kudingeke ukuthi ubeke izingxenye ezingaphezu kuka-100 mils kuma-PCB amakhulu noma aminyene.
Ungawakhipha ama-PCB kumaphaneli ngaphambi noma ngemuva kokuthi eqoqwe.Njengoba amaphaneli e-PCB enza kube lula ukuhlangana, indlela evamile kakhulu ukususa ama-PCB ngemva kokuba iphaneli isiqoqwe.Kodwa-ke, kufanele usebenzise ukunakekelwa okwengeziwe lapho ukhipha ama-PCB kumaphaneli ngemuva kokuthi eqoqwe.
Uma ungenalo ithuluzi elikhethekile lokususa le-PCB, kufanele unakekele ngokukhethekile lapho ukhipha i-PCBS kuphaneli.Ungagobi!
Uma ubungase uphule i-PCB kuphaneli ngaphandle kokunakekela, noma ngisho noma izingxenye ziseduze kakhulu namathebhu, ungase uhlangabezane nomonakalo wezingxenye.Ngaphezu kwalokho, ukuhlanganiswa kwe-solder ngezinye izikhathi kuphuka, okungabangela izinkinga kamuva.Kunconyelwa ukusebenzisa ithuluzi lokusika ukususa ama-PCB ukugwema ukugoba ibhodi.
I-PHILIFAST izinikele ekukhiqizeni i-PCB iminyaka eminingi, futhi isebenzisana namaphethelo e-PCB kahle kakhulu.Uma kukhona noma iyiphi inkinga kumaphrojekthi akho e-PCB, vele uphendukele kochwepheshe ku-PHILIFAST, bazokunikeza isiphakamiso esichwepheshile.
