What do the leads of the components look like when you pull them off? Are they covered in solder? Did the plating stay on the solder fillets attached to the pads?

Dear Steve, I think the plating o fthe leads stay on the solder fillets. The leads of component are free of solder. Regards, Rosen

Sounds like a part problem. You must use the same broker we do. New parts with bend leads, leaded parts "redipped" to turn lead free. The list goes on....

Having never used either DEK or MPM I can't comment on the "big 2" but you might want to include EKRA in your long list. We had a couple of E5's at my last employer and loved them.

I wouldn't normally ask this question, but I'm at my wits end with my current PCB suppliers. Can anyone recommend a competitive, automotive OE quality, TS16949/QS9000, high volume fab shop? Thanks John S.

Friends, I need some help. We have PWB with OSP finish. Which lead free solder paste would you recommend?

i think the most important thing to consider is the # of reflows. is this a double sided assembly? if so OSP degrades during the first LF reflow. also there are many studies out there that show the wetting on OSP is inferior to some of the other comm

How does the machine sense that the fan is working/not working? The fan may be operational but the sense mechanism may be at fault.
