Does anyone know if the ERSA 3/45 can be supplied with top side fluxers? I haven't heard back from the co after my inquiry.

I also operate a 3/45. In order to flux from the top, you would need to have another system on top similar to what you already have on the bottom. There just isn't room for all of the required equipment. Who did you contact at ERSA? I have always had

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

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 4 bottom IR heaters and a 2 zone bottom Quartz heater (2 lamps/4 lamps) and 1 convection heater above zone 1 IR. we have very tight restrictions from customer and I could send profile view to your email if possible

Hard to beleive anything from Kester these days would help. (Unsolicited opinion)

We have been having problems with proper wetting when running mainly lead free but also leaded solder in our Ersa Hotflow 3. Solder either often looks grainy or doesn't flow over the whole pad. This is generally the case when my profile is 170 firs

HI !!! We have the same oven! and yes profiling is hard, but not that bad. Check with the solder paste company for information, right out of my head dont remember for the temps that we use on mondayIcan show you my profile so that youhave an idea

That would be great Armando, thanks. Also, what changes might I make with metal clad light boards (LED). heat transference is tricky with these and the solder is not wetting well.
