No need for drilling holes in the substrate. An innovative clip that can be secured simply by inserting it into the gaps of the BGA.
Malico's Uni-Holder is a groundbreaking BGA heat sink mounting solution that requires no mounting holes, anchor pads, or back plates on the circuit board. To meet the demand for "space-saving" in circuit board design, it adopts a unique structure that utilizes the slight gap (the height of the solder balls) between the PCB and the substrate for fixation. Springs incorporated at the four corners accommodate heat sinks of varying heights, protect components from vibrations during transport, and maintain stable thermal contact. Installation is completed in just a few seconds with a simple "click" without the need for tools, significantly reducing assembly costs. Rework is also easy, allowing for reuse more than 20 times. It offers the flexibility to be introduced immediately as an afterthought in cases where "thermal issues were discovered after design."
