Spikes with our selective solder ERSA machine

Spikes with our selective solder ERSA machine | 14 November, 2000

We have an ERSA machine here where we have solder "spikes" occasionally. We have made sure our flux is dispensing properly, we have adjusted z axis speeds, our preheater is heating properly, adjusted XY speeds, etc. Can anyone think of something we missed/overlooked? please help.

There's a boat load of causes for icicles. Favorites are: * Conveyor speed too high * Conveyor angle too high * Contaminated solder

Have you tried using offsets to begin to move the head away in the Z axis while it is moving in a lateral ( X Y ) direction. The spikes are difficult on the Ersa, but experiment with hitting the location from different directions may help also.
