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

I need advice for locating 23 Gull wing LED's (all in a straight line) in the x,y, and z axis for a SMT PCB. It is a Hewlett Packard LED (P/N HMLA-QH00-01). The application uses a CCD to detect the position of a ball which floats in a resevior for

Anthony: John's points are well taken. All SMT components float to some degree. Fly shit floats more than multi-lead. Well duh!!! I know of no formula. The most cogent discussion is in THE BOOK (Klein Wassink's "Soldering In Electronics), but i

My experience with SMT LED packages is that certain LED package styles tend to float. This floating is caused because the LED is often only terminated on the bottom side of the LED package. Sometimes the LEDs are terminated like a SMT resistor with

Nope, we do not have solder beads, like we said, what we have are near perfect solder fillets except for the portion where the component is "floating OFF" the pcb pads. We are now mucking through the IPC-A-610C for specifications dictation on "tilted

There is a hypotheses floating here that the more surface mount components on a PCB, the percent of missplacments goes up. I'm on the receiving end of this, and looking for backup, or argument for the idea.

Questions are: * Is this 210*C peak temperature measured on the leads of the connector that do not solder well? If not, what is that temperature? * Do you have similar issues with other components on this board? * Do these floating connector leads t

We store alot of our reels on portable wire shelves. We created a "floating island" between the computer station and the SM machines. Push them together when machines are running...wheel near a machine when loading a job.

I was thinking that there must be an excel macro floating around here that can just compare the two lists of data (feeder setups) and spit out what the differences are. Maybe ill create one...
