Subject: [TN] Sideways Resistors
Technetters,
I'm not sure if others see this situation, but it's a somewhat rare
occurrence when we see some resistors, like 0805's, soldered on their
sides. Though it's not a defect per the conditions of IPC-A-610, I am
still curious as to the root cause. I don't know if they somehow get
placed on their side or if they get pulled up that way during soldering.
Our P&P machine is a Mydata MY15, we use no-clean with reflow in air,
HASL boards, 6 mil stencil w/ homeplate apertures.
Any thoughts?
