CSP, or Chip Scale Package, is defined as an LED package with a size equal to or less than 20% of an standard LED chip. The CSP product has integrated component features that do not require soldered wire connections, reducing thermal resistance, reducing heat transfer path, and reducing potential sources of error.

Lets compare the CSP LEDs from leading LED manufactures Nichia, Samsung, Philips Lumileds and Seoul Semiconductor. 

The development of Chip Scale Packaged (Flip Chip or CSP) LEDs is a lighting innovation with several advantages: no substrate, solderless cabling, small size and high optical density.

CSP, or Chip Scale Package LEDs, are 80% smaller than standard LEDs and have all components integrated.  This feature does not require soldered wire connections and reduces thermal resistance, the heat transfer path, and potential sources of damage.

Featuring the Direct Mountable Chip technology the new E17A and E21A LED series from Nichia are direct mountable, packageless, chip scale LEDs which reduce total system cost and increase performance at the same time.

The Direct Mountable Chip technology slashes at one major element of system cost: heat management. With thermal resistance of only 0.3 (℃/W junction to Ts measuring point), heat sinks can be smaller or higher performance can be obtained without increasing the heat sink. 

Compared with 1-3 Watt LEDs from other manufactures the NVSWE21A (304lm@5000K and 2.1W) and the NCSWE17A  (152lm@5000K and 1.05W) are considerably more effective at transferring the heat away from the LED chip.
