Shanghai Nanya Copper Clad Laminate (Nouya) is our main supplier of base materials. Standard boards are produced on NY2150 which is a 150 Tg. material with low Z-axis CTE and excellent anti-CAF performance. Following this link you will find more details on the NY2150 laminate.
Most circuit boards are delivered in panels (clusters), and it´s therefore necessary to attach the boards to the panel in a suitable way. This document shows a number of standard breakaway tabs.
