Thank you ChrisW. I agree completely. The decision to idle the temperature or turn the wave off is primarily a function of machine utilization. Period. The utilization % break even point for idle vs. turning the heat off is calculated by comparing th

This is one of the biggest mistakes with the Lead Free process. We have all listened to the 'industry experts' and followed their advice and unfortunately got it wrong. Keep the dwell times (dependant on alloy selection) the same as Leaded so you are

Which type? * Solder beads (mid-chip solder balls, attached to the waste line of your chip caps and resistors) This is more paste volume related. * Solder balls that tend to be more randomly scattered (as in spattered)? This tends to be more profile

Hello Daxman, Thanks for the input. Yes, the CP2 is closely related to the CP4 and does have the analog servo amps as you deduced. I did a wiggle test on the connectors and found that the x-y-r servo amp alarmed right away and blinked the x axis a
