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, I have noticed we are getting residue on our wave pcb's and it's worse with lead free, since we changed to the flux we are using. We are currently using Avantec VOC Free flux model Ecofree 303. It looks like it's made in Malaysia. Does anyone h

Manage the speed of the board and the speed of the wave to be nearly same at the point where the leads leave the wave.

Frank, ECD (WaveRIDER) and Datapaq (Optimiser) have wave solder machine process control devices. They will check the following: 1. Conveyor speed 2. Preheat Temps 3. Solder Temps 4. Wave Dwell/Contact Times 5. Wave Heights 6. Waves Parallelism Go

hi please could you tell me where the glass you use came from

tell us a your setup parmeters. What is your dwell time? What flux are you using?

Il ne pas de quois. Two most important parameters are: * Solder temperature * Dwell time Immersion depth [1/3 to 2/3 of board thickness] has the least impact of any variable in wave soldering.
