What does "CSP" mean? | 14 September, 1998

Reading some technical report I found the term "CSP", but no explanation. I guess something about Chip Scale Package... but not sure. Could someone please explain it to me? Rgds, Anderson

CSP is an acronym for Chip Scale Package. There are some disputes about the description of a CSP, but the most popular description is that a CSP must be no more than 120% the X and Y dimensions of the silicon die within the package. The CSP is then a die on a carrier substrate. In order to maintain the CSP die to package ratio the CPS is generally a ball grid array. The CSP then can be machine placed onto a PCA. The CSP is not to be confused with a COB (Chip on Board) or Flip Chip. Someone might confirm this, but I believe the term "Micro BGA" has been patented by Intel, thus the term CSP has been used much more. Obviously a great deal of the Micro BGA (fine pitch BGAs) do not fall under the CSP description Steve A

Steve: Excellent description of CSP's. I think the term "Micro BGA" has been trademarked by Amkor.
