Hi everyone, this is my first time on this forum. I've only been an innocent bystander. Until now. I wonder if anyone out there knows of any technical publication (accessible over the net) that explains, in detail, the actual physics involved regardi

In trying to have things run smoothly with placement, I have to do a lot of theta adjustment to get the rotation right during placement. Even if the part looks good on the PnP machine screen sometimes it places differently than what is shown. If I u

For the past few weeks we have experienced an intermitent midas theta error.During normal production the machine times out while just after picking up a component waiting for the theta to center it.Sometimes it fails to leave a tool. Reinitianing the

According to the message guide it just says that it's a error telling you to initiate the Hydra Theta axis. I suppose the encoder for the hydra theta motor could be losing count and causing it to need to be re-initiated, or it could be something to

Are you seeing this problem with the nozzles after an error stop? Well check station 15 confirm nozzle clutch origin. It will cause this problem. If you rotate a shaft (with the machine stopped) 45 degrees and start you will get return theta off and

I'm out here on the leftcoast. Actually, our method for removal is: break down the sides, pull each pin individually. It's tedious and time consuming, but it can be accomplished with little risk of damaging the board. Customers are curious, however.

The only method I would trust measuring the cp or cpk is with an optical coordinate measuring machine used in metrology labs. The machine should have at least ten times better accuracy than the machine to be measured. For a print area of 18"X18" you

| Okay here is the deal. I am fairly new to the company here, but one thing I have noticed is that we read way to many fiducials, in my opinon anyway. One for example is this. One assembly was reading 17 fids. Smallest pitch was .25mil I say you

These ones from ALTERA the QFFP-304 0.5mm weight: 32gr. used to give us a really headache in the past. Not only soldering issue:s but also the placement in x-y-theta! The stencil thickness of ours is 0.13mm and because of ohter compomponent packages,

Well, everything WAS going OK until I started setting up for a board job (40 boards with about 450 components each - many image repeats). We setup 37 feeders with their parts and started defining the pickups and placements. Part #1 is an SOD123 zener
