Your placement machines are too fast. Slow them down and the line will be balanced. This is the easiest way to make the industrial engineers happy.

Good afternoon, Heating/Cooling rates contribute to warpage most of all. Try to tweak you profile so that heating/cooling rate would be minimized. Try to switch cooling blowers off maintaining required peak/TAL. Check copper balance for this PWB, by

Try: * Grainger [www.grainger.com] * Mc Master-Carr [www.mcmaster.com] Use a blast gate like McMaster-Carr 1822K315 located on each port of the machine. These will help balance the air flow entrance to exit as well.

Solder Joint Stress

Here's one take on what you seem to be asking: * After a point, more solder is more stress than the proper amount of solder would produce. * Asymmetrical amounts of solder produce more stress than balanced amounts of solder would produce.

You're correct. This design will have a record amount of 0402 rework for tombstoning and misalignments. Suggest that the pads on each end of all components be the same size in order to balance wetting forces during reflow.

Well, so far Heller certainly scores highly on the balance of price, features & brand reputation (Never heard anyone be mean about them). Be interesting to see what the "cheaper" brands offer, so far they're a bit sleepy.
