  • VSOP: Very Small Outline Package, even smaller than QSOP; 0.4, 0.5 mm or 0.65 mm pin spacing

Quad-in-line

  • TQFP: Thin Quad Flat Pack, a thinner version of PQFP
  • QFN: Quad Flat No-lead, smaller footprint than leaded equivalent
  • LCC: Leadless Chip Carrier, contacts are recessed vertically to "wick-in" solder. Common in aviation electronics because of robustness to mechanical vibration.
  • MLP (MLF): Micro Leadframe Package (Micro Lead-Frame package) with a 0.5 mm contact pitch, no leads (same as QFN)
  • PQFN: Power Quad Flat No-lead, with exposed die-pad[s] for heatsinking

Grid arrays

  • PGA: Pin grid array.
  • BGA: Ball Grid Array, with a square or rectangular array of solder balls on one surface, ball spacing typically 1.27 mm
  • LGA: An array of bare lands only. Similar to in appearance to QFN, but mating is by spring pins within a socket rather than solder.
  • FBGA: Fine pitch Ball Grid Array, with a square or rectangular array of solder balls on one surface
  • LFBGA: Low profile Fine pitch Ball Grid Array, with a square or rectangular array of solder balls on one surface, ball spacing typically 0.8 mm
  • TFBGA: Thin Fine pitch Ball Grid Array, with a square or rectangular array of solder balls on one surface, ball spacing typically 0.5 mm
  • CGA: Column Grid Array, circuit package in which the input and output points are high temperature solder cylinders or columns arranged in a grid pattern.
  • CCGA: Ceramic Column Grid Array, circuit package in which the input and output points are high temperature solder cylinders or columns arranged in a grid pattern. The body of the component is ceramic.
  • μBGA: micro-BGA, with ball spacing less than 1 mm
  • LLP: Lead Less Package, a package with metric pin distribution (0.5 mm pitch).

Non-packaged devices

(although surface-mount, these devices require specific process for assembly):

  • COB: Chip-On-Board; a bare silicon chip, that is usually an integrated circuit, is supplied without a package (usually a lead frame overmolded with epoxy) and is attached, often with epoxy, directly to a circuit board. The chip is then wire bonded and protected from mechanical damage and contamination by an epoxy "glob-top".
  • COF: Chip-On-Flex; a variation of COB, where a chip is mounted directly to a flex circuit.
  • COG: Chip-On-Glass; a variation of COB, where a chip, typically a Liquid crystal display (LCD) controller, is mounted directly on glass:.

How to find package in Eagle

  1. Open the Board editor,
  2. Hit the Add button (or command)
  3. Search for *SOIC*
  4. It will show you all the SOIC packages. There should be one in ref-packages.
