SAC coated leads on certain components require more dwell time. If you find that you have top-side wetting issues, slow the conveyor down a bit or increase your wave height, or, a combination of the 2.

Hi Chrissie, Can you add breakaways to your baord? If you have all 4 sides with components then you'll probably need custome carriers.

I have tried to teach the part a couple of different ways. I have the component taught as a Quad Flat Pack and I am ignoring two of the sides. This has provided better results but still not consistent.

If the solder joint meeting 8.2.5.4, minimum side joint length(D) and also meeting 8.2.5.6, minimum heel fillet height (F) but the heel fillet NOT extend to the mid point of outside bend. It is acceptable?

I facing dewetting problem on Ag/Pd termination(chip component)during reflow process. The solder wetting is pull to terminal side and exhibits dewetting. Any one ever face the same problem and any solutions for the problem?

So if you are getting 100% consignment parts on a single sided board, then you are doing it all for free and getting 3-dollars for a doubled board? Wow, that is pretty cheap.
