Ujongana njani ne-PCB uphawu lokuwela umgca wesahluli?
Kwinkqubo yoyilo lwePCB, ulwahlulo lwendiza yamandla okanye ulwahlulo lwenqwelomoya ephantsi kuya kukhokelela kwinqwelomoya engaphelelanga.Ngale ndlela, xa umqondiso uhanjiswa, inqwelomoya yayo yereferensi iya kudlula ukusuka kwinqwelomoya yamandla ukuya kwenye inqwelomoya yamandla.Le nto ibizwa ngokuba kukwahlulwahlulwa kobude bomqondiso....Funda ngokugqithisileyo -
Ingxoxo kwi-PCB electroplating inkqubo yokuzalisa umngxuma
Ubungakanani beemveliso ze-elektroniki buyancipha kwaye buncinci, kwaye ngokuthe ngqo ukupakisha nge-vias kwi-vias eyimfama yindlela yoyilo loqhagamshelwano oluphezulu.Ukwenza umsebenzi omhle wokupakisha imingxuma, okokuqala, i-flatness yezantsi komngxuma kufuneka yenziwe kakuhle.Zininzi izinto ezenziwayo...Funda ngokugqithisileyo -
Yintoni ukugquma ubhedu?
I-1.I-Copper cladding Into ebizwa ngokuba yi-copper coating, yindawo engasebenziyo kwibhodi yesiphaluka njenge-datum, kwaye emva koko izaliswe ngobhedu oluqinileyo, ezi ndawo zobhedu ziyaziwa nangokuthi ukuzaliswa kobhedu.Ukubaluleka kokugubungela ubhedu kukuba: ukunciphisa i-impedance yomhlaba, ukuphucula amandla okuthintela ukuphazamiseka;Nciphisa ivolthi...Funda ngokugqithisileyo -
Iindidi PCB pads
1. I-square pad Idla ngokusetyenziswa xa amacandelo ebhodi eprintiweyo zikhulu kwaye zimbalwa, kwaye umgca oshicilelweyo ulula.Xa usenza i-PCB ngesandla, ukusebenzisa le pad kulula ukufikelela kwi-2.Round pad Isetyenziswe ngokubanzi kwiibhodi eziprintiweyo ezinecala elinye kunye namacala amabini, iinxalenye zicwangciswe rhoqo ...Funda ngokugqithisileyo -
I-Counterbore
Imingxunya yokubala igrunjwa kwibhodi yesekethe ngenaliti yokukrola intloko ecaba okanye imela yegong, kodwa ayinakugqojozwa (okt, isiqingatha semingxuma).Inxalenye yotshintsho phakathi kodonga lomngxuma kwindawo engaphandle / enkulu yomngxuma idiameter kunye nodonga lomngxuma kweyona diameter incinci yomngxuma ingqamene ne...Funda ngokugqithisileyo -
