<P><FONT face=Verdana>1 , the peak height: peak height is the wave soldering of PCB eat tin height. Its value is generally controlled in the 1/2 ~ 2/3 PCB board thickness too large, the flow of molten solder surface of the PCB , a " bridged"</FONT></P>
<P><FONT face=Verdana>2 , the transmission wave soldering machine when the inclination of the machine in addition to the installation level , the transfer means also adjusting the inclination angle by adjustment of the welding time can be regulated with the PCB surface peaks appropriate angle, and the liquid solder will help PCB faster stripping tin pot so returned .</FONT></P>
<P><FONT face=Verdana>3 , hot air knife: the so-called hot knife, just left after the SMA weld crest , placed at the bottom of SMA " cavity " with a long, narrow openings , elongated cavity physical blowing hot air , just like knife-like , so that " hot knife ."</FONT></P>
<P><FONT face=Verdana>4 , the impact of the purity of the solder wave soldering process, the solder from the PCB contaminants primarily on copper leaching pads , excess copper can lead to an increase in welding defects.</FONT></P>
