Alcohol Content: Ionographs don't like to have the alcohol content too far off from 75%. If that happens, either way, your resistivity will be low. Temperature: Ionographs don't like to be rushed. Stay focused on a proper warmup time. If you don't,

Many different units used over the years; AC (just cooling); TCU (heating and cooling) and ECU (temperature and humidity)... Let me know exactly what you've got, I'll see what I can offer for manual. www.dekhead.com

Hi, Is there any special temperature setting for example , bottom temp should be lower than top temp to prevent component drop. Or any information that can help to prevent component from drop off during reflow of top side.

Hi, I use convection reflow and both top & bottom settings are the same. Is the part too heavy to rely on surface tension? there is an equation that can determine this (aswell as real test i.e. part falling off) We have some SIM Card holders on bot

What type of solder are you using, Lead or Lead-Free? What is the melting point of it? What temperature are you setting your solder bath to? Possible solutions: 1) Give your solder bath a little more time to even out the temperature across the en

We are enclosing our SMT room and will control the Humidity and Temperature of the room. Is there a standard for humidity and temperature for a SMT room and if so what is it. What is protocol if it goes out of tolerance? Do we stop production? Is

Guys, Any of you tried running different setting on the top & bottom side temperature on the reflow oven. I'm trying to address uBGA coplanarity issue using this method. Assume board are flat. Any inputs?

EC - I hope you don't mind that I add to your question... We are running lead free assemblies now and parts that normally hang on upside down are falling off. Any advice on this from others new to lead free?

Hi EC, there was an in depth post dealing with this back in 2000 from the now legendary Bob Willis: http://www.smtnet.com//forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=1468&#Message6342 Cheers, Rob.
