PCB intake speed on a Soltec oven

PCB intake speed on a Soltec oven | 13 December, 2005

Hi,

We have a problem sometimes where our soltec oven will accept another PCB too soon after it's taken the last one, so the PCB will collide with the last PCB that just enter the oven, and knock half the components off one of the boards, and destroy it.

Does anyone know how to set a Soltec oven to pause the in-feed conveyer until the previous PCB has progressed into the oven a safe distance.

Or I thought you could do some kind of SMEMA delay between the conveyer and the oven. Does anyone know of a product like this you can purchase commercially?

I was doing a run myself one night last week just to keep on top of how the plant runs, and I smashed one of the boards this way, and the operators laughed at me the following day. They know about it, and watch for it, but it would be a good problem to solve so it never happens again! The component cost is high.

Regards,

Grant

Depends on the model, year and rev software you have. You can also move the SMEMA sensor into the oven a bit more too.

We use a conveyor before our oven and put a footswitch on it to send the next board or jump the pins so that it just sends the board depending on delay needed.

If this is happening the way I think it must be, then part of the problem is the input conveyor being faster than the oven speed. Can you slow the conveyor down? Of course if you do this, expect the operators to complain.

Also consider the possibility of adding a sensor to the conveyor that would be mounted in the oven.

Hi,

Thanks for the ideas, and I liked URL's idea of seeing if we can move the in feed sensor, that might hold the board wile the other is feeding in.

Our in feed conveyer is also much faster than the oven, and I wonder if we can change that. I will need to check that out.

Thanks for the ideas guys, and it's a shame this is not a simple setting in the software. Soltec make great equipment, but I don't know what mental patient who writes their software was thinking.

The Delta Wave has the worlds worst software. What equpment would make turning on the timer mode so hard, and what fool makes a machine beep a warning when it's not even running. What's it warning about?

Why's the fluxer 100% full all the way until it runs out? Why is not timer not able to be disabled on Sunday, so we have to turn on for 1 min, and then off again. Why does the timer not turn on, unless you set the time off to a future time, and let the current time run through the turn off time? There is so much wrong, and I wish they would fix it.

I notice in this industry that every time they do fix something important in the software, it gets released as a new model of the machine, and you have to upgrade to the new model just for the better software.

Grant

Haha Grant, totally agree about the software on the deltawave, why does every recepy not have its own fluxer set? Why does the fluxer speed doesnt change automatically when you change the conveyor speed? They really should think of kicking their softwareengineers all the way out of holland, and plz not into belgium, that is if they have any. That said still love the hardware. I thought you were talking about the oven though, on the deltawave you can easely change the inputconveyor speed in the options menu under input/output conveyor.

Hi,

Yes, I was talking about the oven, but then thinking about Soltec in general and about things the software really should be able to do, got me worked up on the Deltawave.

I guess the frustration with it's software is not far from the surface. Soltec make absolutely great hardware, and the software on the Soltec reflow oven is also fantastic, but what happened to the Delta wave? Same company, but what a difference between products.

Writing the Deltawave software's not something I would want on my resume.

But then if I interviewed an engineer that had that written on his resume, I would actually be impressed he could write without using the very same neurons that's keeping his/her heart beating.

You ever noticed when you complain about problems with software on products the sales guys just laugh and think your joking. I'm not really joking. I don't know why they have a computer on the front, and they could have just used a mechanical timer, as the software does little else.

I should setup a "Deltawave software experiences blog" server on the computer, so it's put to some use.

But I am just getting worked up again, and that cannot be good for my health!

Regards,

Grant

True,

But it was a rather nice looking PC on our 6622C....

And have you considered that without a PC how could they give us all of those really helpful alarms that seem to go off every 5 mins? (really handy as you're showing customers around. "That's a nice wave, what's up with it?" "I don't think it likes your aftershave sir")

Cheers,

Rob.

Hi,

That's true, and the plant just does not look high tech without that PC on the front of the wave. I should donate the wasted processor cycles to the SETI screen saver if it's still going on.
