We all know the Lead Free process is trend, so we trial run it, now it is only my comment that we have a good achievement after several tries,we have taken serveral photos about Lead Free process with ErsaScope. 1.The surface of the solder joint are

Dump the pot and put in the SN100C. Don't mix, too much tin.

I should specify that I am using SAC 305 as well.

proper pad geometries, accurate placement, and good reflow profile. Are you having problems right now?

Use the thermal recipe suggested by YOUR paste supplier, as the starting point.

Hi Armando Hotflow 7 is a big machine and one of the best Reflow ovens around (in my opinion), well suited for Lead Free. A typical 1.6mm board has the following settings for Lead Free SAC305 paste All Temperature settings are Top and Bottom Prehea

I have the ability to offer both SAC and SN100C lead free alloys to my customer base. What might occur if a customer is already using SAC305 in their wave and they want to save money and go to SN100C. They now are mixing, tin,silver,copper with tin,c

I am doing lead free testing on a Vitronics selective machine with a 4 mm nozzle. The finishes I am testing are ENIG, ImSn, and ImAg. The problem I am encountering is achieving good top side wetting. Has anyone had any luck with this type of an ap

with lead-free solders, one would expect to find less instances of tombstoning. this is because SAC alloys are not eutectic and melt over a range of temp (usually 217-220 deg C) instead of at a single temperature. therefore the forces due to solder s

As we have vitronics oven(SMR610A) made in dec,1997,which has 5 heating zones and 2 cooling zones. For Lead free soldering what should be our baseline for low/medium boards.we have gathered profiles from various paste manufacturers,however we don't k
