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?

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

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

We are manufacturing an NPI board for a Customer and they want us to wash the board using a Saponifier wash. However, one of the SMT parts cannot be placed through a wash process. Has anyone ever had to encapsulate a component to prevent water da

Have you considered mounting this component after the assembly has been washed. Then, mounting the component and cleaning its solder joints individually. Alternatively, have you considered using alternative cleaning solutions to a saponifier (and a

It's inductor [choke] number 511. Probably used for EMI suppression on the monitor line. Look here: * http://www.antennex.com/shack/Dec99/beads.htm * http://lists.contesting.com/_topband/1998-11/msg00165.html *

Bourns is quite a high end name in the electronics industry & you usually pay a premium for percieved Swiss precision engineering. If your card is far east built it is much more likely to have an inductor on from Murata, Panasonic, or one of the Chi
