Are you using adjustable workboard holders or dedicated ones? Are both heads lined up exactly the same(using the b.e.c. template? Are parts formed correctly and lined up with the component holes on both sides(heads)?

Universal has been producing Lightning pick and place heads for some years now. How are these heads performing these days? Speed, component range, reliability. Who has worked with them?

As far as I know, ALL data in the machine, so the machine configuration and offsets, the component data and the PCB mounting data are all held in the one battery-backed memory. If it goes completely, you lose ALL of the above. But, you will see what

Does it fail to function or does it function outside of acceptable tolerances? If the latter I wouldn't know what to think, but if the former I would feel obligated to suspect solder quality or maybe even a component problem with the elevated lead-

You say, "we have encountered solder wicking on components ..." We expect to see wicking on solder connections. Maybe we're just using different terminology. Please describe the problem that you're seeing.

Hi Dave, The solder has tended to wet the component termination of Ag/Pd (chip capacitor) but has not wetted the pads, whereas the solder has wetted both termination & pads when using Ag/Ni/Sn finishes. Thks

Thanks Dave. But I do not understand why the solder being wicking away by the component itself. Does Ag/Pd finishes has stronger wettability than LF HASL finishes ? Rgds

Whe have the Mirtec about 2 years now, the question is, that when you have 100 components to check he give's 20 to 30 failures that no failures are. are there people they have the same problem?

I agree with Steve Thomas, The Quad IVC is a good machine for what you have described, it is small, chugs right along and is dependable. 1 head makes for some boredome watching it but is well over the 500 component mark. Good Luck with your purchase.

Ah, see Steve, I was right. It depends Marcin. If you use the same temps in each zone for all your product, vary you converyor speed. This will negate any waiting time between profiles. Slowing the speed will decrease your Delta-T to an acceptabl
