Product profile
1.1 General description
This is a type of heavy copper PCB built on FR-4 substrate with Tg 130°C for the application
of power supplies DC-DC converter. It's a 4 layer board at 1.60 mm thick with 4oz outer layer
and 3oz inner layer. White silkscreen over green solder mask on both top and bottom side.
Surface finish is immersion gold on pads. The base material is used from ITEQ IT-158, entire
board supplying 32 up per panel. They're fabricated per IPC 6012 Class 2 using supplied
Gerber data. Each 25 panels are packed for shipment.
