Keypad PCB Hard Gold Circuit Board Built On Tg170 FR-4 With Green Solder Mask
(Printed circuits boards are custom-made products, the picture and parameters shown are just for reference)
1.1 General description
This is a type of double sided circuit board built on FR-4 substrate with Tg 170°C for the application of keypad. It's 1.6 mm thick with white silkscreen(Taiyo) on green solder mask (Taiyo) and hard gold on pads. The base material is from Shengyi supplying 1 up PCB per panel. They're fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 25 boards are packed for shipment.
