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

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

In PCB design, a BGA (Ball Grid Array) package typically determines the number of layers that a Printed Circuit Board should have. However, the 4-layer board with a BGA package is commonly used than a 2-layer than an 8-layer PCB. On the other hand, t

Thanks for the link. Their is a white silkscreen underneath the BGA instead of a green soldermask. Attached is a picture of the BGA. Does these affect the solderability for the component.

The total inductance of a chip capacitor is determined both by its length to width ratio and by the mutual inductance coupling between its electrodes. So, a 1210 chip size has a lower inductance than a 1206 chip. Check with your supplier for recomm

The padsfor large heat sinks are being designed on our boards with large copper ground planes surrounding them by our engineers. I am having great difficulty keeping the reflow temperature below 230 degrees in order for the temperature of the copper
