Company Profile

High Density FR4 Tg170 Automotive Printed Circuit Board With Immersion Gold

Via in Pad PCB High Density Multilayer PCB Via Filled Circuit Board with Immersion Gold for GPS Tracking Devices

1.1 General description

This is a type of 6 layer printed circuit board built on FR-4 Tg170 substrate for the application of GPS Tracking Devices. It's 1.6 mm thick with white silkscreen on green solder mask and immersion gold on pads. The base material is from ITEQ supplying 1 up single board. Vias with 0.3mm are resin filled and plated flatly (via in pad). They're fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 25 boards are packed for shipment.

1.2 Features and benifits

RoHS compliant and suitable for high thermal reliability needs

Excellent surface planarity for CSP mounted components to reduce failure rate during assembly and soldering.

Reliability test, insulation resistance test and ionic contamination test

16000 square meter workshop
