Can you etch where you want to solder to? But you would need harsh chemicals to do that. The whole point of chrome is to not chemically react.

You can weld (spot) to chrome. Maybe you could weld a nickel tab to the chrome part?

isd.jww: First, the original poster is talking about pads, not component leads. Second, you're correct that chrome plated component leads can be attached by spot welding or crimping a solderable tab to the lead and then soldering the tab to the boa

That's not going to work in this case. The substrate has very small pads designed for a micro BGA die. Thanks for the suggestion though.

Has anyone had any experience of using High Melting Point Solder paste in production. We have started to trial some boards using the Solder Paste and are experiencing poor solder joints and solder joints that look grainy.

Compared to 63/37, solder with high tin content: * Requires higher reflow temperatures * Demands tighter process control * Results in duller, more grainy looking solder connections Tell us about the specific problem that you seek help in solving.

Looks like a 2SD1623 from Sanyo. Check the following datasheet, look below the "electrical characteristics" for component marking info. http://www.zymcu.com/datasheet/device/2sb1123.pdf

Thanks, I'd found that first fixya link but not the second. If you're copy-and-pasting that list of part id sites, better check them -- all but one are broken links.

Looks to me exactly what flux does to a board when its not washed correctly. Seems to me that it could be someone did some rework and didn't wash the board? Or the board wasn't washed correctly in the first place? Just speculation though.

Hello, If anyone has a technical question concerning Assembleon or Philips equipment then ask it hear. I got quite some year experience on these machine and I might be able to help you with an email.
