01005 components and reflow profiles

Electronics Forum | Mon Apr 09 19:50:33 EDT 2012 | action_101

Hello, We're building some boards with 01005's and the only issue we are running into is the solder is not reflowing. It's the damnest thing, we are having no issues with the printing process or placing the components, the two areas we thought we wo

I made my own wave measuring device using KIC2000 system. KIC2000 has automatic wave detection, so now I have a profiler for both reflow ovens and wave solder. The delmat carrier only cost $500. A guy, Samir, from this forum gave me the idea, actu

Lead-free and Leaded solder in the same reflow

Hi All, I�ve been doing some research on the issue of running lead-free solder paste and leaded solder paste through reflow at the same time. The point with this would be to process all standard leaded components with Lead paste while also processi

Try an intermediate paste like Loctite/Henkle 218. It's design is to be used in a mixed lead/lead-free process.

Lead-free and Leaded solder in the same reflow

Hi, SAC BGA's in a SnPb reflow process can be achieved by ensuring the temp. on the BGA is at a peak min of 220�C and a time above 207-210�C for 60 - 90 Sec. Lower temperatures have shown incomplete mixing of alloys and some voiding.

Hi Tristian, I work at the 1st company listed- the link you posted is our website. We have updated our clamps for those type of SMT process carriers. Feel free to email me @ wmartin@gscusa.net or call 972-494-1911 and I can help you out. Sorry for

Lead-free and Leaded solder in the same reflow

Today's regular Sn-Pb paste chemistries are designed to run at higher peak temperatures ensuring that your lead-free alloys will coalesce with your regular Sn-Pb solder. That being said, it is do-able to solder both types in one oven. Generally, wit

At my last employer, we ran a number of tests to make a "Hybrid" profile work (same profile Joe lists) . It worked great for everything but BGAs. The problem (6 months ago) was using parts not rated for lead free reflow temps. As the market fills wit

Nitrogen use in reflow and wave

Electronics Forum | Sat Apr 20 10:12:16 EDT 2002 | davef

If people use an inert gas, they use nitrogen for mass soldering. Inert gases get progressively more expensive as you move down the periodic table. Many times no-clean flux is less active than other flux types. So, people use an inert gas to lower

Sr. Tech, you are right in that there is no verification of the profile. We are a Class 3 high mix OEM. We have visual inspection after SMT. We have not seen problems with wetting, grainy solder, cold solder, charred boards, etc. that would indicate
