| | R&D is currently designing a board with smt components on both sides of the board. They are adding a 16 pin IC Gull wing. on the bottom side of the board. I have asked for only caps and resistors to be placed on the bottom side. Is there a recomm

I tried soldering to several of the black pads and was successful, the solder stuck with no hesitation. so i guess this is not truly "black pad"? would that be a correct statement? What causes this blackening that looks like oxidation under the mic

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

The pads you use for Reflow will be be fine for handsolder. Russ

Could anyone point me in the direction of finding out how much strength an SMT pad has in relation to being pulled away from the substrate/laminate? We are in process of trying to build a 6mil thick board and want to know if a chip can be placed onto

Hi Nikhilesh, It was a long time ago, but we used to buy the nickel in reels then had a cut and feed station on the smt machine with selectable sizes. We did many types of boards in very large volumes, and usually the Nickel strip was soldered to t

This sounds like a job for ssd. No pad shapes to worry about. Look into http://www.sipad.net and please contact me off line to discuss it. Matt Kehoe mkehoe@sipad.net

We've noticed that there are many different recommendations for pad sizes for various SMT parts. This seems to vary wildly from manufacturer to manufacturer for the same case sizes. Is there any standards that can used used to specify these sizes?

There a several things you can do to prevent the solder wicking down the hole with the current design, and that's where you should focus. Cost goes up as you go down the list, but in neither case do you need to respin the board, have solder starvatio
