Does any one have any experince with heatsinking a 240 lead QFP such as the Lattice Orca to the PCB? I have a customer who would like to know how this might be done. We are thinking of using some solder paste under the center of the part, or using

One common practice, depending on what is on the other side of the PCB and how much heat you need to draw away from the part, is to manufacture a pseudo-heatsink into the board itself. It looks like a large tinned pad but has a dense array of vias f

Opinions. I have a large finned heatsink that we place over a D2pak transistor. This heatsink is designed to heatsink the transistor through the junction of the pad area that the transistor is attached to. The paste pattern we chose was small dots ar

Using moss fets attached to sub heatsink and hard coat anodizing sub heatsink at higher cost and erratic performance. Looking for thermal tape, insulator to replace hard coat that will prevent shorting.

How to measure the max allowable force when we press the heatsink at the attachment process. I was posted with question by my customer, " how to I ensure that the force I use to attach the heatsink does not causing any damage to the solder joint on t

Hi, Can anyone tell me where I can get heatsinks for DPAK devices? It will be used for cooling IGBTs. Preferably, the heatsink device should be soldered for easy production. Thanks alot.

If we received heatsinks with blisters on the contact surface, like you describe, we'd reject them. We want that surface to be perfectly flat. Google "heatsink flatness" for more. For instance: http://www.heatsink-guide.com/content.php?content=hea
