SAC305 and Sn100c alloys

Electronics Forum | Thu Jan 29 17:04:43 EST 2009 | jeffjarmato

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

SAC305 and Selective Soldering

Electronics Forum | Wed Sep 18 14:12:40 EDT 2013 | pjchonis

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

PB-Free HASL and Leaded Solder

Electronics Forum | Thu May 13 09:52:34 EDT 2021 | winston_one

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

wave soldering and solder bridge

As someone with a LOT of experience with the "low cost" alternative alloys, primarily SACX, I have one simple question....Are these shorts a new phenomena? WAS your process in control, and all of a sudden it's not? If the answer is YES, take a look a

SN100C alloy positive and negatives

Electronics Forum | Wed Dec 24 15:28:17 EST 2008 | edmentzer

We use SN100C for wave soldering and hand Lead free soldering and have had very good results. The wire cored solder for hand soldering flows good and makes very good solder joints. The SN100C in the wave solder machine also works very good. We use

paste Sn42/Bi58 and Lead Finish

Sure you can use it it with leaded HASL. Recognize that ... * Your Sn42/Bi58 will no linger be Sn42/Bi58 * Your leaded HASL will no longer be the same leaded HASL that walked in the door to your plant * Lead from HASL coatings can diffuse through the

PB-Free HASL and Leaded Solder

Electronics Forum | Thu May 13 20:40:25 EDT 2021 | winston_one

Yes, we can't use pure Pb PROCESS. And as I say we will not use it anyway, as we have lead-free BGA's, LGAs, component with Solder Charged Terminations... It's became almost normal practice to solder it with leaded solder pastes. In this case peak re

Lead/Lead Free In-Line Wash and UT cleaners

If that's the case, let your customer go. I have run into this situation recently. Q. Why do you not run a dedicated line for lead free? A. You (the customer) give less than 12 weeks forcast and expect us to have a dedicated line for your product?

Sn99Cu07 and Sn100

Electronics Forum | Tue Oct 18 10:36:46 EDT 2022 | winston_one

Dear proffessionals! Question is about this alloys - Sn99Cu07 and Sn100 (Sn100C,Sn100Ni+ etc.). Is it O'k to mix them? In my case to use Sn99Cu07 as addition to selective soldering machine bath with Sn100C? Main components are the same, but minor add

Mixed SAC105 and SAC305

Electronics Forum | Thu May 29 13:12:10 EDT 2008 | yam6rider

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.
