Dear TechNetters

I have several questions:

Have any of you used Tamura solderpaste Solder paste RMA - 012 - FP (
Sn62.8/Pb36.8/Ag0.4)?  Did you have any issues with it?  There
specification limits are not the traditional solder paste limits.  It is as
follows:

Set peak temp between 210 - 240 deg C
Adjust melting time over 200 deg C for 20 to 60 seconds
Ramp rate < 4 deg C

Does anyone know why they would set the peak temperatures so high and time
above liquidus so high??

Thanks for the input.
