a circuit in which the interconnecting wires have been replaced by conductive strips printed, etched, etc., onto an insulating board. It may also include similarly formed components on the baseboard., lülitus, mille ühendusjuhid on moodustatud isoleerplaadile trükkimise abil. Lülituse juhistikule vastav kujutis trükitakse happekindla lakiga (hrl. sõeltrükimeetodil) isoleerplaati katvale vasekihile.
