Multilayer PCB 24 Layer Printed Circuit Board Built On High Temperature FR-4 With 50 Ohm / 100 Ohm Impedance for Industrial controls
General description
This is a type of high multilayer PCB built on FR-4 substrate with Tg 170°C for the application of Industrial controls with 24 layer copper track. It's 3.7 mm thick with white silkscreen(Taiyo) on green solder mask (Taiyo) and immersion gold on pads. This is also an impedance controlled PCB with single-end impedance of 50 ohm and differential impedance of 100 ohm. The base material is from ITEQ supplying single up PCB. They're fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 10 panels are packed for shipment.
Features and benifits
Excellent thermal reliability and CAF resistance providing long-term reliability for industrial and automobile application.
Long storage time ( It can be stored for more than 1 year in vacuum bag)
The signal lines form a constant low impedance to the ground
Micro-section and thermal stress test
16000 square meter workshop
Small quantity order is accepted
ISO9001, ISO14001, IATF16949, UL Certified
We can find its Applications in transmitter, GSM Modem, 3G WiFi Router, phase Shifter, embedded Controller, hard drives.
