That is to say, ordinary PCB substrate materials not only produce softening, deformation, melting and other phenomena at high temperatures, but also show a sharp decline in mechanical and electrical characteristics (I think everyone does not want to see this in their products).
Lokho ukusho ukuthi, izinto ezijwayelekile ze-PCB substrate ezishisa kakhulu azivezi nje ukuthamba, ukusonteka, ukuncibilika nezinye izinto, kepha futhi nokusebenza kwezimpawu zomshini, zikagesi zokwehla okucijile (angicabangi ukuthi sifuna ukubona imikhiqizo yabo ivela lesi simo).
