Pophunzira zamagetsi, nthawi zambiri timazindikira bolodi losindikizidwa (PCB) ndi dera lophatikizika (IC), anthu ambiri "amasokonezeka" pamalingaliro awiriwa. M'malo mwake, sizili zovuta, lero tifotokozera kusiyana pakati pa PCB ndi dera lophatikizika.
Kodi PCB ndi chiyani?
Printed Circuit Board, yomwe imadziwikanso kuti Printed Circuit Board in Chinese, ndi gawo lofunikira lamagetsi, gulu lothandizira la zida zamagetsi ndi chonyamulira chamagetsi olumikizirana ndi zida zamagetsi. Chifukwa chakuti amapangidwa ndi makina osindikizira, amatchedwa bolodi "losindikizidwa".
Bolodi yamakono yamakono, imapangidwa makamaka ndi mzere ndi Surface (Pattern), Dielectric layer (Dielectric), dzenje (Kupyolera mu dzenje / kudzera), kuteteza inki yowotcherera (Solder resistant / Solder Mask), kusindikiza pazithunzi (Legend / Marking / Silk screen ), mankhwala apamwamba, Surface Finish), etc.
Ubwino wa PCB: kachulukidwe kwambiri, kudalirika kwakukulu, kapangidwe kake, kupangika, kuyeserera, kusanja, kusanja.
Kodi dera lophatikizika ndi chiyani?
Dera lophatikizika ndi chipangizo chaching'ono chamagetsi kapena gawo. Pogwiritsa ntchito njira inayake, zigawozi ndi kulumikiza mawaya monga ma transistors, resistors, capacitors ndi ma inductors omwe amafunikira mu dera amapangidwa pa kachidutswa kakang'ono kapena zidutswa zing'onozing'ono za semiconductor chip kapena dielectric substrate ndiyeno zimayikidwa mu chipolopolo kuti zikhale microstructure. ndi ntchito zofunika dera. Zigawo zonse zakhala zikuphatikizidwa mwadongosolo, zomwe zimapangitsa kuti zipangizo zamagetsi zikhale gawo lalikulu la miniaturization, kuchepa kwa mphamvu, nzeru, ndi kudalirika kwakukulu. Imaimiridwa ndi chilembo "IC" mudera.
Malinga ndi ntchito ndi kapangidwe ka chigawo chophatikizika, chikhoza kugawidwa m'mabwalo ophatikizika a analogi, chigawo chophatikizika cha digito ndi digito / analogi yosakanikirana yosakanikirana.
Dera lophatikizika lili ndi maubwino ang'onoang'ono, opepuka, waya wocheperako, ndi malo owotcherera, moyo wautali, kudalirika kwakukulu, magwiridwe antchito abwino, ndi zina zambiri.
Ubale pakati pa PCB ndi gawo lophatikizika.
Dera lophatikizika limatchedwa kuphatikizika kwa chip, monga boardboard ya Northbridge chip, CPU mkati, imatchedwa Integrated circuit, dzina loyambirira limatchedwanso Integrated block. Ndipo PCB ndiye gulu ladera lomwe timalidziwa nthawi zambiri ndikusindikizidwa pa tchipisi tating'onoting'ono towotcherera.
Dongosolo lophatikizika (IC) limawotcherera ku bolodi la PCB. PCB board ndiye chonyamulira cha integrated circuit (IC).
M'mawu osavuta, dera lophatikizika ndi dera lonse lophatikizidwa mu chip, lomwe ndi lonse. Ikawonongeka mkati, chip chidzawonongeka. PCB imatha kuwotcherera zida zokha, ndipo zida zitha kusinthidwa ngati zitasweka.
