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).
Okungukuthi, abavamile PCB substrate izinto ashisa kakhulu hhayi kuphela ukukhiqiza ukuthambisa, ukusonteka, ukuncibilika kanye nezinye izenzakalo, kodwa futhi ukusebenza mechanical, izici kagesi nokwehla abukhali (Angicabangi sifuna ukubona avele imikhiqizo yabo lesi simo).
