     All component suppliers specify a recommended reflow profile. 
        Start from there and see what works with your process within the

Hi,
     
I am fairly new to the PCB industry.  But when I read the book about the 
reflow soldering process, it takes normally 213C as the peak soldering temp 
when the melting point of the solder may be, say 183C.
     
My understanding is that, it takes sometime to melt and acheive a
good solder joint.  But how to determine 213C?  Or put it this way, what 
is the minimum peak temp. one should maintain?  Have you come across any 
literatures that talk about it ?
     
Any input is appreciated.
     
Thanks.
Y.F. Wong
