Basic ndondomeko ya PCB msonkhano

PCB msonkhano ndi ndondomeko kupanga kusindikizidwa matabwa dera, njira kupanga kuti amasintha zipangizo mu PCB mavabodi zinthu zamagetsi.Itha kugwiritsidwa ntchito m'mafakitale ambiri, kuphatikiza zankhondo ndi zakuthambo.Lero tiphunzira za chidziwitso chokhudzana ndi PCB pamodzi.

PCB ndi kachidutswa kakang'ono ka dielectric kamene kamakhala ndi njira zoyendetsera.Njirazi zimagwirizanitsa zida zosiyanasiyana zamagetsi.Amagwiritsidwanso ntchito kulumikiza zigawo ndi sockets pa matabwa ozungulira osindikizidwa.PCB msonkhano ndi ndondomeko kupanga matabwa dera zinthu pakompyuta.Njirayi imaphatikizapo etching pagawo la dielectric ndikuwonjezera zamagetsi ku gawo lapansi.

Gawo loyamba lathunthu la msonkhano wa PCB ndikupanga mapangidwe a PCB.Mapangidwewo adapangidwa pogwiritsa ntchito pulogalamu ya CAD (Computer Aided Design).Mapangidwewo akamaliza, amatumizidwa ku dongosolo la CAM.Dongosolo la CAM limagwiritsa ntchito kapangidwe kake kupanga njira zamakina ndi malangizo ofunikira kupanga PCB.Chotsatira ndikuyika chitsanzo chomwe mukufuna pa gawo lapansi, lomwe nthawi zambiri limapangidwa pogwiritsa ntchito chithunzithunzi.Pambuyo pa etching chitsanzo, zipangizo zamagetsi zimayikidwa pa gawo lapansi ndi soldered.Pambuyo pa soldering ndondomeko yatha, PCB imatsukidwa ndikuwunikidwa kuti ikhale yabwino.Ikadutsa kuyendera, ndi yokonzeka kugwiritsidwa ntchito.

Poyerekeza ndi njira zachikhalidwe za PCB, kukonza msonkhano wamakono wa SMT kuli ndi maubwino ambiri.Chimodzi mwazabwino kwambiri ndikuti msonkhano wa SMT umalola kupanga zovuta kwambiri kuposa njira zina.Izi zili choncho chifukwa msonkhano wa SMT sufuna mabowo obowola kuti agwirizane ndi zigawo zosiyanasiyana.Izi zikutanthauza kuti mapangidwe ovuta kwambiri amatha kupangidwa popanda kudandaula za zofooka za kubowola kwakuthupi.Phindu lina la msonkhano wa SMT ndikuti lithamanga kwambiri kuposa njira zina.Masitepe onse ofunikira amachitidwa pa makina amodzi.Izi zikutanthauza kuti palibe chifukwa chosuntha PCB kuchokera ku makina kupita ku wina, zomwe zimapulumutsa nthawi yambiri.

Msonkhano wa SMT ndi njira yotsika mtengo kwambiri yopangira ma PCB pazinthu zamagetsi.Izi zili choncho chifukwa imathamanga kwambiri kuposa njira zina, zomwe zikutanthauza kuti pamafunika nthawi yochepa komanso ndalama kuti mupange chiwerengero chofanana cha misonkhano ya PCB.Koma ili ndi kuipa kwake.Chimodzi mwazovuta zazikulu ndikuti ndizovuta kwambiri kukonza misonkhano ya PCB yopangidwa pogwiritsa ntchito njirayi.Izi zili choncho chifukwa derali ndi lovuta kwambiri kuposa njira zina.

Zomwe zili pamwambazi ndizodziwa za PCB zomwe ndikufuna kugawana nanu.Msonkhano wa SMT pakadali pano ndiyo njira yabwino kwambiri yopangira msonkhano wa PCB.Kuti mudziwe zambiri pa izi, chonde tithandizeni.
