Hi

I have my own opinions on critical features at flowsolder machines but I
would like any other opinions in case I'm neglecting something. To this end
I would like to ask what you consider to be the most important features
involved in getting the best soldering quality from a flow solder machine.
Statistical process control is planned. The machine in question is a
Blundell single wave with foam fluxer.

Parameters being monitored (independently of machine) are bath temperature,
solder contamination levels, and spec gravity of flux. No clean flux is not
being used.

Parameters not being measured (except by flowsolder m/c display panel where
possible)are titration levels of flux, flux application performance (level
check), wave and bath  height, lambda, omega, conveyor speed/angle, topside
preheat temp, air knife angle, time motor is on prior to running boards. I
would consider these points worth addressing - any opinions?

Thanks

Bob Gallagher
