Makes us wonder how well the connections on the component match with the pads on the board.

I have some large ROHS SMT inductors that are moving during the reflow process. I have tried adding extra solder, gluing and doing both. I don't know what else to try, any suggestions?

Since the inductor is electro-magnetic, that means the device is composite of coil and ferrite metal. The inductor inside the reflow oven meets with blower motors which close to the inductor and generate magnetic field. With such conditions, Lawren

Makes us wonder how well the connections on the > component match with the pads on the board. The pads are actually larger than the leads on the part, but I think we may have figured it out. We believe the conveyor vibration is causing it. When we

SMT adhesive? Might be able to cure in wave process?

You'll be searching for a while... There's no way you can have that large of inductance in an 0805 package. You'd be hard-pressed to even have a 1mH in an 0805.

Thanks for the suggestions! It ended up being that a wire on the amplifier card in the lower drawer came loose and was making intermittent contact. Tightened all the wires down and the problem has gone away. Now we have a new problem. We had to repla

I am having difficulty programming/inspecting a large SMT Relay. It is a dual in-line through-hole package with 5 leads per side formed to a gullwing configuration on .100" pitch. We have programmed it as a SOW10 pkg and got usable lighting values bu

Edmund, I agree with Wolfgang there is no reason for 0603s to be falling from the bottom side during the top side reflow. I assume what you are having problems with is a higher mass component like a large tantalum, inductor, or perhaps an active de
