Uretse gusobanukirwa itandukaniro riri hagati ya PCB zihuta cyane n'izikoresha frequency nyinshi, ni ngombwa kwibanda ku ngamba zihariye zo kubungabunga ubuziranenge bw'ibimenyetso no kugabanya ingaruka mbi mu miterere y'imashini zikoresha frequency nyinshi. Gukurikiza uburyo bwo kugenzura inzira ya impedance, uburyo bwiza bwo gufunga, no gutekereza ku buryo bufatika. gushyira ibiceni ingingo z'ingenzi zo kunoza imiterere ya PCB kugira ngo ikoreshwe ku buryo bworoshye.

Byongeye kandi, gusunika imipaka y'imirongo ishoboka muri PCB bisaba kwibanda ku dushya mu guteza imbere ibikoresho, ubuhanga bwo gukora ibintu neza, n'imiterere yihariye yo gukusanya amakuru. Binyuze muri izi ntambwe, abashushanya bashobora gushakisha imipaka mishya mu bushobozi bwo gukoresha amakuru menshi mu gihe bakemura ibibazo biterwa n'imiterere y'ibikoresho n'ingaruka z'imirongo yo kohereza amakuru.

Ubu buryo bwuzuye bwo kunoza imiterere ya PCB kugira ngo ikoreshwe ku buryo bwo hejuru butuma ibikoresho by'ikoranabuhanga bishobora gukora neza ku buryo bwizewe ku murongo wo hejuru nta kwangiza ubuziranenge bw'ibimenyetso cyangwa imikorere yabyo. Hamwe no kwibanda ku mikorere myiza no gutera imbere mu ikoranabuhanga, ahazaza ho gushushanya PCB ifite umurongo wo hejuru hari icyizere gikomeye cyo gutanga imikorere myiza mu buryo butandukanye.
