I-PCB yomlawuli womnyango yibhodi yesekethe eprintiweyo (PCB) elawula umnyango okanye amasango okunciphisa ukufikelela kwindawo ethile.I-PCB yokulawula umnyango ngokuqhelekileyo iqukethe ibhodi yesekethe eprintiweyo kunye namacandelo esekethe edibeneyo (IC), kuquka i-transistors, i-capacitors, resistors, kunye namanye amacandelo, i-Door controller PCB inokuphinda ibandakanye iimpawu ezongezelelweyo ezifana ne-keypad, i-sensor, i-relays, kunye namanye amacandelo, i-Door controller PCB idla ngokuxhunywa kwinkqubo yokulawula ukufikelela, evumela abasebenzisi ukulawula ukufikelela kwindawo ethile.
