Sinikezela nge-PCB ekumgangatho ophezulu kunye nomhla wokuhanjiswa okukhawulezayo iminyaka emininzi, iqela leenjineli zobuNgcali, njengale mveliso, inamaleko asi-8 ubukhulu obuyi-2.00mm ubukhulu be-EING 3U” PCB, kubandakanywa umngxuma oyimfama kunye nokutshisa, i-plating vias, njalo njalo, ubungakanani bomngxuma omncinci ngu-0.1mm, umkhondo yi-3 mil / 3mil, ukuba uziva unomdla, okanye unenye i-PCB efuna ukuvelisa, nceda uqhagamshelane nam ngokukhululekileyo, imfuno yakho iya kwamkelwa ngalo lonke ixesha.
