Double Sided SinkPAD Board

What Double Sided SinkPAD Board is?

The Double sided SinkPAD board consists of at least two layers of trace circuit, and there’re at least one circuit layer on both top and bottom side of board, a dielectric (non-conducting) layer, a metal core/pedestal which normally is copper.

As there’re circuit layer on both sides, so engineer can put more (about 2 times, ideally) components on the same size circuit to realize more function, more complicated design, comparing to 1 Layer SinkPAD board or 2 layers SinkPAD board.

There’s no PTH (plated through hole) on double sided SinkPAD board, because the limitation of manufacturing process, which different from double sided Metal Core PCB which has a lot of PTH, and thermal PAD of LED will be put directly on copper core, also belonging to Direct Thermal Path (DTP) board too, but engineer needs to consider where the heat sink will be if he want more fast heat transferring, as there’re always components on both sides, and that make double sides SinkPAD board designing becoming more difficult & complex comparing to 1L SinkPAD board, or 2L SinkPAD board.

Advantages of Utilizing Double Sided SinkPAD Board:

  • Put more components on the both top and bottom, design more complicated circuit board.
  • It adopts the thermoelectric separation structure, the Lumens depreciation of the LED is minimized, and the life of the lamp is prolonged.
  • Suitable for matching single high-power lamp, such as Cree XPL, XML, XHP; Osram LED, etc., also COB package LED
  • High power semiconductors (transistors, thyristors, diodes) as well as resistors.
  • A variety of Surface Finishing are available according to different demands. (ENIG, OSP, Immersion Tin, ENEPIG, HAL) with excellent reliability of the surface treatment layer.

Application of Double Sided SinkPAD Board

  • High Power LED (up to 200W).
  • High semiconductors (transistors, thyristors, diodes) as well as resistors.
