Am I reading your post correctly? You will print PCBs and not populate them until up to 24 hours later? And you can assemble level 3 components at 30C and 90% humidity, you just have to pro-rate the exposure time. (I don't recommend having those con

Tom, If you need the parts... I can quote and supply them.. A good tradesman can change these parts. You do not necessarily need a Yamaha trained guy to do it. The only issue issue after the exchange of the parts is calibration of the machine, which

I'm investigating heat transfer by 1st order approximation between PCB and ambient air via encapsulate material (epoxy or gel or silicone), they have thermal conductivity of 0.2W/C but it hard to find specific heat capacity and density. Has anyone

Has there been any studies on the effect of the depth of the fluxing cavity for dipping PoP components? I've heard that the cavity should be 50% of the ball diameter and I also heard that the cavity should be 2/3 of the ball height (which may or may

I have an oven that now wants me to tune and can't do anything until I enter a password. The big problem is I don't know the password. Any way to find it or bypass it. Figured it out, the machine has a battery back-up and it needed to be replaced.
