PCB with Peelable Mask Double Sided Circuit Board Built on Tg170 FR-4 Coating HASL.

(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 2 layers PCB board built on FR-4 Tg170 substrate for the application of 8 Port Switch. It's 1.6 mm thick with white silkscreen on green solder mask and HASL (pb free) on pads. The big pads on top layer are protected by Peelable masks. The base material is from ITEQ supplying 8 up boards per panel. They're fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 25 panels are packed for shipment.

1.2 Features and benefits
