Ejò PCB

A Ejò PCB, tabi Ejò-orisun Printed Circuit Board, ni awọn wọpọ iru ti tejede Circuit ọkọ lo ninu Electronics. Ọrọ naa “PCB Ejò” ni gbogbogbo n tọka si PCB kan ti o nlo bàbà bi ohun elo imudani akọkọ fun iṣẹ-yika rẹ. Ejò jẹ lilo pupọ nitori adaṣe itanna ti o dara julọ, ductility, ati idiyele kekere ti o jo.

Ninu PCB Ejò, awọn fẹlẹfẹlẹ tinrin ti bàbà ni a fi si ọkan tabi ẹgbẹ mejeeji ti sobusitireti ti kii ṣe adaṣe, nigbagbogbo ṣe awọn ohun elo bii FR-4 (laminate epoxy fiber ti a fi agbara mu), CEM-1 (iwe kan ati ohun elo resini epoxy), tabi polytetrafluoroethylene (PTFE, ti a mọ ni Teflon). Awọn fẹlẹfẹlẹ Ejò lẹhinna ni apẹrẹ nipa lilo fọtolithography ati awọn ilana etching lati ṣẹda awọn ipa ọna Circuit ti o fẹ, sisopọ ọpọlọpọ awọn paati itanna gẹgẹbi awọn resistors, capacitors, ati awọn iyika iṣọpọ.
