We're trying out 0603 packages on some 0805 footprints (at this stage only on some test boards) since our vendor tells us the 0805's are going to be getting harder to get, and more expensive to pay for. I understand the IPC footprint for the two is

I am completely new to SMT design and for my next project I plan to use SMT for the first time. Since production volumes of the PCB's will be low, hand soldering is definitely an option, and will be necessary for my prototype PCB assembly. My proble

If your words imaged correctly, it seems a bit strange to have a trace that is wider than the pad where it connects, because we�re used to seeing a narrower trace connecting to a wider pad. It�s tough to determine what the designer was thinking abou

Steve- We had the same trouble with 0805 Panasonic film caps. We had some tombstoning and open solder joints (non-wetting). We found two problems...like you, we changed our pad design to meet their recommendation. Also, they were able to suppl

I just encountered a BGA design were in, underneath the BGA is a silkscreen that covered the entire bottom of the component except for the copper pads. Can you give any information and advice for this type of design.

Greetings, Does anybody out there have any experience with 0306 capacitors (not 0603). I am trying to find a pad design for this component. I have searched the archives to no avail. The component is .06 long by .03 wide with .007" solder terminat

Thanks alot for the info

You say that there is no green solder mask around the lands of the BGA only silk screen. If that is the case I would be concerned about the solderabilty of the component if the silk screen gets onto the pads. The application of solder mask is much mo

Thanks Dave, I was looking in the Murata data base and couldn't even find the part (Even though they are the ones making it)let alone the pad dims. This part looks like it could be fun anyway. Russ
