Impedance controlled PCB Built on FR-4 With 4 Layer Copper
 
  1.1 General description
  This is a type of multilayer PCB built on FR-4 substrate with Tg 150°C for the application of Heart monitors. It's 1.6 mm thick with white silkscreen(Taiyo) on green solder mask (Taiyo) and immersion gold on pads. The base material is from ITEQ supplying 8 up PCBs 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 benifits
  Outstanding thermal resistance and suitable for lead-free process
Excellent surface planarity, helpful for PCBs with BGA packages to reduce failure rate during assembly and soldering.
Improved the speed of signal transmission
Reliability test, insulation resistance test and ionic contamination test
Delivery on time. Higher than 98% on-time-delivery rate.
Small quantity order is accepted
Customer complaint rate: <1%
 
  1.3 Application
  Preamplifier, Navigation System, GPS Tracking Devices, GPS Device, AC Drives, Biometric Access Control, Mobile Broadband Router, Electronics Assembly, Memory Module, Weather analysis
