Novastar is JUNK, that is why you cannot get repeatable results. Check the conveyor rails, you will find they are warped. Novastar uses cheap, non-machined rails. Straight from china or india. Their stuff is garbage. Best to swallow the loss and star

Agreed, I just bought a Electrovert Vectra Elite and have been very pleased with it thus far. I got the dual pot option for lead free changeovers and that has worked great. I can change pots in under 5 minutes, not counting the time to warm up.

I was just wanting to know some of the advantages/disadvantages of going gold immersion? Is this neccessary for Lead free?

Wayne, I haven't seen anything indicating that Gold Immersion is necessary for lead free... However, it is my companies preferred finish for lead free assemblies. We've taken this stance for the following reasons: 1. Better solder quality on th

Yash Sutariya's paper [ http://www.saturnelectronics.com/docs/Getting_the_Lead_Out.pdf ] does a good job of describing the benefits and limitations of popular LF solderability protection coatings.

hi, i'd like to know how do you maintain cleaness of your solder frames after production - we use both SnPb and leadfree process, we clean in alcohol and ultrasonic but the frames look white and i wonder if we do not damage the structure??? best re

Can�t help but just notice that RoHaaS affects more then just solder joint reliability. As long as the mat is �green� all should be just fine. For more info check http://www.rohaas.com Sorry couldn�t resist

The heat you are putting into it is replacing heat it loses. The greater the delta T the greater the heat loss. You lose less heat if the pot is cold. Yes you need to use more heat at the start of the day but it is less than the heat needed to keep i

Your cost savings will be minimal over-all, depending on how many shifts you run. You cost saving will be zero if you use the timer on your machine. If the power goes out for a couple of hour during the night, your pot will be cold the next morning.

Nope, not at all. Uh-uh, no did not say that. Just had a lot of power outages here at nite that mess with the timing if you use the timer.
