Standard PCB FR4 TG135 2 layer PCB 1oz LF HASL Low Cost High Quality Unclad Printed Circuit Boards

Standard FR4 laminate, low cost board, Use FR4 material with TG > 135°C and td > 335°, Finished board thickness is to be 0.062”+/-10%, Apply green liquid photo imageable solder mask to both sides of the board over bare copper, Silkscreen is white, permanent, organic, non-conductive ink, HAL (Hot Air Solder Level) Lead-Free, ship as panel, In order to reduce costs, to minimize the risk of errors arising during manufacture or for specific technical reasons, PCBs can be combined in a panel. Panels can be simple or complex. We can separate them by milling, milling with bridges, scoring or a combination between all. The panel border on V-cut panels is mainly for ease of handling during the assembly process (tooling holes, fiducials). The PCBs are connected by non-routed bars (bridges), it is called Panel of PCBs divided by routing, and used for higher size accuracy.
