Abstract

Foreliggende oppfinnelse angår en fremgangsmåte for oppvarming, og et trykt kretskort som omfatter et varmeelement (90) som genererer varme som er nødvendig for å oppvarme komponenter på et trykt kretskort. Det trykte kretskortet omfatter en varmeleder (40) mellom varmeelementet (90) og komponenten som skal oppvarmes, og varmelederen mottar varme generert av varmeelementet (90) og leder varmen langs det trykte krets-kortets overflate, under nedre overflate på komponenten som skal oppvarmes. Dessuten omfatter det trykte kretskortet lederdeler (15, 70) som er smalere enn varmelederen (40), eller som har et mindre tverrsnittsareal enn varmelederen har, og som begrenser varmeoverføring bort fra varmelederen (40) til en annen komponent enn den som skal oppvarmes, når varmelederen (40) fungerer som jordplan eller signalbane.
