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

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

Check with your paste manufacturer for a recommended baseling. The paste manufacturers generally have a database by oven that gives optimal performance for their paste. It's only a baseline, and does need to be adjusted based on the thermal foot pr

Let me be the first to suggest; Get a better oven. 5 zones minimum. If you can't, you will have to have some way of profiling the board. Does the oven have thermocouple ports? If not you will have to buy some kind of termperature datalogger. Mayb
