Next Generation LED Solution Provider With Wide Array of Products in LED Modules Portfolio
SinkPADTM is a patent pending metal core printed circuit board (MCPCB) technology which provides a direct thermal path to the hot LED.
It is an alternative PCB technology to the conventional Aluminum PCB or MCPCB providing DIRECT THERMAL PATH solutions for medium to high power LEDs.
SinkPADTM MCPCB improves conduction cooling thermal path.
IMS PCB is made of three layers. Circuit layer, dielectric layer and a base metal layer. The circuit layer is electrically isolated from the base metal by a thermally conductive dielectric layer.
It is directly proportional to the thermal conductivity of the base material. i.e. ~135W/m.k in case of Aluminum and ~385W/m.k in case of copper. Most designs use Aluminum metal as a base material.
No, It is designed to be used with the LEDs which has electrically neutral thermal pad. Such as Cree XPG, XPE, XPC, XTE, XBD, XML, MTG, Luxeon Rebel & Luxeon M from Philips Lumiled, Oslon SSL & Oslon square from Osram, Nichia N219, Seoul Semiconductor Z5P / Z5M, Samsung 3535, Bridgelux SM4, LZC & LZP from LEDEngin etc.
Yes; it is specifically developed to lower junction temperature of medium to high power LEDs. Any LED above 1.0W power
Yes, However LEDs are required to have electrically neutral thermal pad.
Assembly process is the same as conventional MCPCB or Aluminum PCB.
Electrical functionality may be compromised.
Conventional MCPCB uses a thermally conductive dielectric layer to bond circuit layer with base metal (Aluminum or Copper) layer. The key to thermal performance of MCPCB lies in its dielectric layer. Eventhough thermally conductive dielectric has higher thermal performance compared to standard dielectric material it is still a weakest link in the conduction thermal path. SinkPADTM MCPCB approach overcomes this limitation and eliminates use of a dielectric material completely from a conduction thermal path. SinkPADTM technology provides "DIRECT THERMAL PATH", lowering LED junction temperature.
No, SinkPADTM PCB can be made using any thermally conductive metal or metal composites. However aluminum is the most common base material used in SinkPADTM MCPCB due to its light weight, and least expensive properties
No, we can use your existing MCPCB or Aluminum PCB gerber data.
SinkPADTM MCPCB's are premium in cost and performance compare to a conventional MCPCB, but very competitive to a high performance dielectric MCPCB.
