We're having trouble with a TO-252 DPAK from Fairchild (MC7805CDT) and our existing land pattern. The land pattern calculator on the IPC site doesn't have anything available that matches it (there are no TO-252's available on the pull downs), and I'

The IPC-EM-782 reads as follows: the adjustment factor is usually intended to increase the Z dimension slightly, but brings the Z maximum up to an even equivalent. Example if Zmax is 2.100mm then you would enter an adjustment factor of .100mm. The ad

Dave, you are THE master of the search. I made the lame assumption that if they'd had layout specs. for a part, it would be part of the spec. Bad assumption. The layout for the decal from that page you linked to is exactly what I needed. I look

Thanks, Larry, more good info. I think my designer has that spec. in his library. What we DID find that while we had the proper pattern called out in our in house spec. sheet for the part, the designers don't look at the spec. sheets. They just grab

In the beginning, there was TO-5. And it was good. Flushed with success, they created TO-220. It too was good. Then came SMT. It was better than some things, but then again ... In these early days, there was a haze on the horizon that blocked t

I have a customer want to add an SMD coil to the board, which they used to hand soldering all the time. I want to know is there footprint/land pattern size that I should follow? Any recommendation?

we have some problems in soldering joints such as insufficient solder and misalignment on some RC0402 and CC0402,i don't have a pic here. our SMT enginner doubts the PCB land pattern is at the fault.here is what we measured results.pad length:0.9mm,
