A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing

PCB: Board specifications Part Number Revision Number of copper layers in your board: Single Sided = 1 Layer Double Sided = 2 Layers Multilayer = 3 to 10 Layers Material: Most widely used material is FR4. FR4(130Tg) FR4(170Tg) CEM1 Thickness of board. Most commonly used thickness is 0.062 0.062 0.031 0.047 0.093 0.125 Type of plating on board Pb-Free options include Immersion Gold and Silver, Pb-Free HAL. Finish Plating Leaded Solder Lead Free Solder (RoHS) Immersion Gold (RoHS) Immersion Silver (RoHS) White Tin (RoHS) OSP Copper Weight Standard is 1oz copper per sq. ft. Extra current needs more copper thickness. For 2 or more oz., board must meet the design guidelines 1 oz 2 oz 3 oz 4 oz Dimensions: Overall board size. HEIGHT x WIDTH SMD Side: Surface Mount Device/Component used on the board. None Top Side Bottom Side Both Sides Distance from the center of SMD pads to the center of the nearest SMD pad: 0.3mm = 0.012" 0.4mm = 0.016" 0.5mm = 0.020" 0.6mm = 0.024" SMD Pitch n/a 0.015 0.020 0.025 over 0.025 SMD Pads: Approximate number of Surface Mount Pads on both sides of the board. Approx# Holes: Approximate number of holes used in the board. Smallest Hole: The smallest finish hole on the board. 0.010 0.011 0.012 0.013 0.014 0.015 over 0.015 Minimum Trace/Space 0.008 0.005 0.006 0.007 Mask Sides: Number of solder mask sides. Standard is Green LPI = Liquid Photo Imageable. With SMOBC = Solder Mask Over Bare Copper. None Top Side Bottom Side Both Sides Silkscreen: Number of Silkscreen or Legend. Standard color is White. None Top Side Bottom Side Both Sides GoldFingers: Total number of gold fingers on the board. Cutouts/Slots: Number of internal cutouts or slots needed to be routed. Routing: Individual if finish board is individually routed. Scoring if boards are in panel separated by score line. Route/Retain if boards are in panel separated by tab/route. Route/Retain/Scoring if boards are in panel separated by tab/route and score line. Individual Scoring Route/Retain Route/Retain/Scoring Testing: The type of Electrical testing. For production quantities, boards needs to be electrically tested. Comparative is the least expensive type. Number of boards: Board Quantities
