Beschreibung
Zusammenfassung:	A printed wiring board with a component connection pad, such as a solder pad, providing thermal stress compensation for a surface mount circuit component and method for making such a pad. The component connection pad includes opposed groups of multiple conductive fingers that are mutually connected at their far ends and separated at their near ends where they have surfaces for mounting a single surface mount circuit component. L'invention porte sur une carte de câblage imprimée comprenant un plot de connexion de composant, tel qu'un plot de soudure, fournissant une compensation de contrainte thermique pour un composant de circuit à montage en surface et sur un procédé de réalisation d'un tel plot. Le plot de connexion de composant comprend des groupes opposés de multiples doigts conducteurs qui sont mutuellement connectés au niveau de leurs extrémités éloignées et séparés au niveau de leurs extrémités proches où ils ont des surfaces pour monter un composant de circuit à montage en surface unique.
