wave profiling for ersa ews500

So are you saying that you cannot reach 110C at 1 location without raising another location to excessive preheat temp? If so, sometimes slowing down the conveyor and dropping the preheat temps will help you get equal temps. I do not know this machi

we have a new ersa ews500 wave machine and are experiencing difficulty in profiling for lead free. particular issue is reaching 110c preheat for large TH electrolitic caps while maintaining 110-170c on 1/4 watt resistors in same area

Lead free selective solder

Electronics Forum | Sat Jun 24 07:23:06 EDT 2017 | tch

You will need to preheat the boards for a lead free selective solder process. A preheat module is critical for any wave or selective solder process, if you don't get the board preheated properly the solder is going to resist flowing to the top of the

Spikes with our selective solder ERSA machine

Electronics Forum | Tue Nov 14 16:06:27 EST 2000 | zorox

We have an ERSA machine here where we have solder "spikes" occasionally. We have made sure our flux is dispensing properly, we have adjusted z axis speeds, our preheater is heating properly, adjusted XY speeds, etc. Can anyone think of something we m

We have an Ersa and an Ace machine. The Ersa is made for bigger volumes of boards. Programming is longer/harder and not as user friendly. If your running 100 boards or less.....the Ace is the way to go. If you need flexibility the Ace is better.

It could be lack of preheat or flux. You can verify the flux by hand applying. I'll bet it's lack of preheat though. That's usually the case with selective solder.

ZSWHPS-12S selective soldering machine

Electronics Forum | Mon Aug 02 17:09:12 EDT 2021 | alexeyzb

What do you think about ZSWHPS-12S selective soldering machine? It looks like Ersa but more cheaper. Please, can you give me some advantages and disadvantages? I need facts, which i can check.

Laser selective solder machine

There are several types of lasers to do laser soldering. Panasonic also has a high intensity light that can solder as well. I've tried em' all and two over whelming things stand out when it comes to this type of soldering. #1 is preheat. It seems
