Description This is a double side Adapter PCB that can accept 0.5mm pitch ICs on one side. The pcb can let you solder your QFP, TQFP, LQFP, FQFP packages using standard 0.1 inch header for use on Breadboard or Perforated boards. The Adapter PCB is perfect for quick prototype and testing of fine pitch ICs when you don’t want to invest into costly high density pcb manufacturing. The adapter pcb has capacity of 144 capacitors on back side. User can decouple any pin out of 144 pins to GND through these 144 capacitors. This feature makes this adapter pcb suitable for various noise sensitive chips such as CPLDs, FPGA, 8/16/32 Bit Microcontrollers etc.   Technical Specifications IC Package Pin Pitch: 0.5mm Header Pin Pitch: 2.54mm (0.1in) Center Thermal Pad: Yes Thermal Pad thermal relief vias: Yes Maximum Number of Capacitors on Back: 144 Copper GND Polygon: Yes , on back side Additional GND pins: Yes Pin Numbers Text: Yes on Top side for every pin Capacitor number Text: Yes on bottom side for every pin.
