I work for a small SMT contract manufacturer with a couple SMT lines utilizing both old (IP1, CP3) and newer (CP643, XP242)Fuji machines. We have an issue with an IP1 that has us stumped. One of the device locations has no power. After some basic tro

I'm not finding 24Vdc at any feeder location?! I checked all pins with the coresponding feeder activated through the I/O and a key in the emergency disconnect. Am I not using the correct procedure to check for my 24V?

Do IP1's use MFU's like the IP2's ? If so I can most likely tell you what the problem is.... Please advise.

All of the IP-1's I have seen use a fixed feeder bank. No MFU's which is where the board is located for IP-II's. Jerry

We swapped the solid state relay for zone 5 bottom to zone 5 top but the problem came up once a while. As for noise protection, there are jumpers at E1 to E8 and E9 to E16. They are hardware filters and prevent noise spikes from affecting thermocoupl

We used a photo-optic sensor powered off the conveyor after the oven that is tied to a relay that trips when a board is seen at the sensor which causes a buzzer to go off. Very simple to make. Good luck.

Have seen this problem on other types of oven and it was caused by failed solid state relays that energise the heaters.

Are both photocouplers exactly the same ? More importantly, do they have exactly the same metalisation on their legs ? I have experience where same relay devices have different leg metalisations (one was matte tin / one was gold over platinum over n

You're thinking correctly in trying to improve your process. Can you change to a more active flux? Look at the copper that connects to the center pin. You may need to relay-out the board to add a wagon wheel style thermal relief in that area.

Yes. Typically terminals, large relays, displays, parts with mounted heatsinks. This is typically what you see on hand-insertion lines. Other parts with specialized packaging may not be able to be auto-inserted either. Most axial and radial leade
