Want to update this question a little, I know it appears few years ago, but I hope there is some updates... We have to assembly few samples of motherboards with this kind of finish (customer mistake during pcb order). Normally we can use leaded sold

Just like to know what you guys thoughts regarding mixed alloys. Production run SAC305 and some components are SAC105. So, which profile should you follow. SAC105? or SAC305.

I've got the same scenario. and I followed SAC105.

Why not follow SAC305? you would do so for any other component finish wouldn't you? A component finish of pure Sn would also not call for a pure Sn profile, would it?

I run two different waves here one with SAC305 with aqueous flux the other with SN100C and No clean flux. Does anyone see any issues with running product through either machine of course after changing the Flux type? I also only use SAC305 alloy for

Good day all, I wanted to get a quick poll from the folks running SAC305 in their selective soldering equipment. How are final results? How repeatable is the process, any machine related failures? pumps? nozzles? etc... I am just looking to get a

Hello Bachman. SAC305 is the most common lead-free solder alloy, not only for wave soldering but also selective. Most of our selective customers (especially automotive) are using SAC305. What is more important than the alloy to consider is the flux

The Immersion gold is not a problem with BGAs specifically but "black pad" which can be present anywhere. The unfortunate thing with BGAs is you cannot see it. Personally I hate white tin. It is okay for single sided boards running no-clean, but c

I agree! I am using a SAC305 no clean from Alpha. I have noticed that even hand probing with volt meter leads requires me to press very hard on the pads to bust through the flux residue.
