I have never used Manganin wire. I understand it is difficult to solder. Should we use a move active flux. It will be a .25mm, PTFE insulated manganin wire spliced to thermistor wires. Thanks coeps

A little adition to Norm's statement: Sn-Pb intermettalic compounds do not accept solder as they are (even without being oxidized).

Below 40 microinches = Bad Solderability With pitches getting smaller and smaller flatness becomes more of an issue, but it's not to be achieved by blowing ALL solder off the pads.

Few questions: - wich type of C-CGA ? (CAST or CLASP column to ceramic attach) - column pitch ? - column count ? - capped (with lid) ? or capless (c4 die on top)? - PCB board zize and thickness ? - volume of solder paste ? - Clean or not Clean so

Hello everybody, We have a new product having a lot of open gold area. solder splashes during the reflow is a pain in the... Its an extremely small PCB and kapton taping is not an option. Stencil is at 10% reduction, Cleaning after every cycle. Reflo

hi, Are there users of Aura - a wave soldering machine of Automation ?. I d like to buy a copy of the manuals and to ask a few questions. Thanks

From my understanding (and I am not a metalurgist)Most Lead free solders can be intercahngeable.The alloy created should be stable. The issue is if you add Leaded solder to the joint. Obviously, research and testing is still pending. cal

We saw this quite a bit, I want to say 5 or 6 years ago, but it's probably more like 10 years ago. It's caused by poor solder mask crue. Talk to your board fabricator about solutions.

Dear Frank, could it be that your component legs are coated with a leadfree finish? This can have an inpact on soldering when your temp.peak in only 220�C and the melting point of pure Tin is 237�C. Best regards, Daniel

Dear Al, did you developed the survivel pil? As manufacturer of paste we can evaluate the solderability of your components.If you can organise us 10 samples, then we do the rest.Send me a mail to get my adress. Best regards, Daniel
