Double Sided High Tg Printed Circuit Board Made on IT-180ATC with Immersion Gold for Telemetry Communications
Double Sided High Tg Printed Circuit Board Made on IT-180ATC with Immersion Gold for Telemetry Communications
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
Brief Introduction
This is a type of standard double sided high temperature PCB which is built on ITEQ’s IT-180ATC laminate. (For more details about IT-180ATC, please refer to High Tg Lead Free Printed Circuit Board (PCB) on IT-180ATC and IT-180GNBS with 0.5oz-3oz Copper 0.5-3.2mm Thick). There are 10 boards paneled up in the array. They are 1.6mm thick with 2oz copper, coating with immersion gold on pads and green solder mask protection for substrate. 25 pieces are vacuum packed for shipment.
Applications
Automotive (Engine room ECU)
Backplanes
Data Storage
Server and Networking
Telecommunications
