We use a Wave Solder Plated Through Hole (PTH) assembly process to install a TO-220 Chip Package in the PCB board that we manufacture and have experienced lower yields on a number of boards with this component due to Bridges. The bridges on the TO-22

daveF - thank you for your reply. We ave tried both the 90 and 180 degree rotation in addition to other solutions mentioned in previous post but with no or minimal success.

Use fuji vision #12. That is for the resistor network types. You cant inspect the individual leads. Vision type 12 tell the CP that this is a rectangular chip with terminals. You don't need to define the leads in the PD just the overall shape of th

We run these all the time. Agree with other posts. I tried a few times to read leads on these with mixed results. Leadless is best. On GSM - run as leadless or chip and crank the lighting up on 2.6 or 4.0 ULC. You should get good centering.

I have not seen expiration date on parts so far. I have seen people uses 10 year old parts too as long as it solders good.

Your target ppm in on the Juki machine a take it. So it's rejecting these parts due to the inversion? Any way to disable this. A right-side down resistor is not ideal, but it will certainly work electrically. Reese

Perhaps neither. I assume the part is T&R. It's flipping inside the tape before placement. I don't know how the nozzle could be doing it. There could be excess vibration on the feeder which is causing the part to flip. Just a thought.

I have seen this on a MyDATA machine and we had to slow our feed rate of the feeder down. That seemed to do the trick. We concluded the carrier tape was too large for the part, but our vendor didn't really seem to care.

Is there anyone that makes a pick and place glue dot for surface mount chip components (B stage epoxy dot in a carrier tape)? Thanks, Rich
