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

We've had a few problems with printing a flex-rigid PWB, and I'm hoping some of you could throw some opinions/suggestions my way. Our PWB is about 8" x 11" divided into two parts (side A & B) by 2 wide flex cables. Each of these flex cables is ab

Hi!, Can anyone help me with problems with Solder voids after reflow curing on D2PAK heatsinks? I would like to remove the gas from the solder paste; can centrifuge help?How many minutes should a solder paste in a tube be processed in a softener? Ho

I've been in PRODUCTRONICA and I've found something that could be interesting for SMT designers : SMT heatsinks for Dpac also lead free! The website is http://www.placeit-smt.com Hope this help someone! It was something I was searching for... Bye

Hi Dave I think it might be difficult to get an off the shelf item. WE have designed and supplied several in the past, both pnumatic and manual, if we can be of any help please let me know.

There's bits of the LAN9311-NZW around (Mouser), but although the package looks the same size, it looks like it's got a heatsink pad under the device - you have to check with your designers/approvals to see if you can use it.

Datum: Many times the requirement for a heat sink is anticipated poorly by the designer. So, adding a clip becomes burdensome and too expensive for a respin. Other times, there is no off the shelf clip for the component, as you say. So, a well des

Yes, All six new (LF ready kit) thermocouples are tested good.I would like to say boards are populated on both side back to back with two heavy PLCC's side by side just like having heatsinks and ground plane.Some Odd design.Next try will be to have a
