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

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

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

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

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

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.

For the past year now we have been printing adhesive with no real problems. Our printing ranges from 0603's to SOIC using a variation of aperture sizes and metal thickness foils. The crucial parameters are : aperture sizes : These obviously depend o

If you are talking about smt components I'd say absolutely not. If these are through hole components I'd say possibly (if they are in rows, and not a whole lot of them). The machine is slow, but the quality is great. Creating a wave profile takes abo

To answer Gary's question: Gary, you will need a production board, thermal profiler, flux vendors product data sheet on the flux you intend to use, maybe your wave vendor service engineer or wave solder vendor contact (unless you know your wave) and
