 We have done several tests and in general, you have to turn on the Holdtime (in menu) to achieve full wetting at the top temperature. Also be sure to place the board in the middle of the oven since the sides do not heat as much.

-; 2024-05-09 : Old laptop gone, so I tried 4 different machines. The ez-reflow software has a custom FTDI driver that is blocked by anything newer than Windows 7. It will not install on Windows XP, 10 or 11. I eventually found a donated machine that could do this, but since it's highly inscure - do not ever connect this machine to our nwetwork in any way! The machine does not have a working battery, so it must be plugged in when using. The machine also has no CMOS battery, so you'll need to restart it quite a few times before it starts. It will eventually though.

-Eurocircuit recommends using SAC305 (SN96,5Ag3.0Cu0.5), a lead free paste that typically melts at around 227°C. It is however not fully melted at this temperature [https://aimsolder.com/technical-articles/reflow-limbo-how-low-can-we-go#:~:text=SAC305%20begins%20to%20melt%20at,temperature%20window%20of%20233%20%E2%80%93%20255. as explained here]: ''SAC305 begins to melt at 217°C, reaching its fully liquid state at approximately 220.6°C. Recommended reflow temperatures are typically at least 13°C higher than melting temperatures; hence the SAC305 peak temperature window of 233 – 255. Applying the 13-degree guideline to the SnCuNi alloy results in a minimum peak temperature recommendation of 240°C. It’s that 7-degree difference in minimum reflow temperatures that generates the fear – of cold joints, incomplete wetting, inconsistent IMC formation or other reliability issues - if the peak temperature of a solder joint falls into that questionable space between 233 and 240°C.''

 When precise temperature readings on the PCB are required, place the external sensor thermocouple directly to the PCB in order to measure the temperature on its surface. Secure it with Kaptopn tape or solder it using solder wire with high melting tmperature to the top or the bottom of the PCB.
