Immersion Silver PCB on 0.4mm FR-4 ITEQ 4 Layer Circuit Board for Security Systems
1.1 General description
This is a type of 4 layer printed circuit board built on FR-4 substrate with mid-Tg 150°C for the application of Security Systems. It's only 0.4 mm thick with white silkscreen(Taiyo) on green solder mask (Nanya) and immersion silver on pads. The base material is from Taiwan ITEQ supplying 1 up PCB per panel. They're fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 30 boards are packed for shipment.
