WebSurface Mount Technology (SMT) is a more recent method of arranging electronic components on printed circuit boards (PCB). Before this method was developed, engineers would use leads to connect electronic components through holes in circuit boards. It took careful planning to ensure that we made all the leads correctly on different kinds of boards. WebThe CTE value shows the thermal expansion of the base material. CTE-z represents the z-axis and is e.g. due to the stability of the vias, of high importance. A higher Tg value favors a low CTE-z value which represents the absolute expansion in the z-axis.
