Chifukwa chiyani? bolodi losindikizidwa mukufuna kuwongolera kwa impedance?
Mu mzere wamakina opatsira pa chipangizo chamagetsi, kukana komwe kumakumana ndi ma frequency apamwamba kapena mafunde amagetsi akufalikira kumatchedwa impedance.Chifukwa chiyani ma board a PCB amayenera kukhala osasokoneza panthawi yopanga fakitale ya board board?Tiyeni tipende pazifukwa 4 izi:
1. The Pulogalamu ya PCB fakitale ya board board iyenera kuganizira za plugging ndi kukhazikitsa zida zamagetsi, ndipo kugwirizana kwa SMT patch pambuyo pake kumafunikanso kuganizira zinthu monga ma conductivity ndi magwiridwe antchito amawu, kotero kutsika kwa impedance kumakhala bwinoko.
2. The PCB dera bolodi akukumana mkuwa kumira, electroplating malata (kapena mankhwala plating, matenthedwe kupopera malata), cholumikizira soldering ndi njira zina pakupanga ndondomeko.Zida zomwe zimagwiritsidwa ntchito ziyenera kukhala zochepetsetsa zochepetsera kuti zitsimikizire kuti mtengo wonse wa impedance wa bolodi la dera Ntchito yokhazikika ikhoza kutheka kokha pamene zofunikira za khalidwe la mankhwala zikwaniritsidwa.
3. The malata plating wa matabwa pcb dera ndi ambiri sachedwa mavuto kupanga gulu lonse dera, ndipo ndi kugwirizana kiyi kuti zimakhudza impedance;vuto lake lalikulu ndi makutidwe ndi okosijeni zosavuta kapena deliquescence, osauka solderability, kupanga gulu dera zovuta solder ndi kwambiri impedance.Kukwera, zomwe zimapangitsa kuti pakhale kusasunthika bwino kapena kusakhazikika kwa bolodi lonse.
4. Makondakitala mu bolodi ya PCB ya fakitale ya board board amatumiza ma siginecha osiyanasiyana.Dera lokhalo lidzasintha mtengo wa impedance chifukwa cha etching, makulidwe a stack, waya m'lifupi ndi zinthu zina, zomwe zingapangitse kuti chizindikirocho chisokonezeke ndikupita ku bolodi.Kuchita kumatsika, chifukwa chake muyenera kuwongolera mtengo wa impedance mkati mwamitundu ina
