What is the composition of tin to lead in the "Liquid Tinner"? It's been my experience that the higher the tin, the duller the solder appears. I've used 63/37 and 70/30 that both look shiny, whereas 80/20 does look dull. Just another thought to cons

Please help!! Operators are currently using soldering irons set at approx 450 degrees C, this i realise is far to high, but can some one tell me the effect on the PCB and joint at this temp and the recommended temp for soldering.

Mr.Dave.F has given an exhaustive answer. I just want to mention that some attention could be paid to the plating & contaminants on the PCB. We have experienced longer soldering time due to the presence of contaminants on the plated surface.

The best suggestion one can offer is to view the archive section of this site. It is full of discussions, suggestions, advertising, claims, counter-claims, etc. Just search under the words �stencil cleaning�. Mike Konrad www.aqueoustech.com konrad

Mike, I know that. I wanted to be talking to Bayanbaru. Plus, I know you have no placement machines. You use ultrasonic plastic welders and screwdrivers. Dave
