We have tested SN100C and SAC305 in our selective solder machine (Ersa Versaflow). We wanted to test both alloys in the selective first because the investment in filling the pots is minimal. In our initial tests the SN100C alloy appears to be the bes

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.

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

Is there a risk of popcorning plastic components during wave soldering? (The PCB is first surface mounted, reflowed and washed. It is sometimes left in air environment for as long as 48 h before the throgh hole components are mounted and they are wa

For better quality in our wave solder process i want to start with an improvement project (to eliminate solderbridges). Does somebody know what are reachable ppm rates for solderbridges in a wave soldering process? The boards are simple. Only some

Hello, does anyone know if it's possible to wave solder 0402 components? Are there drawbacks? Where can I find technical details about recommended footprint and glue point? Last question: are there suggestions about wave soldering for ic with 0,635mm
