Any suggestions on a good pick n place machine that can handle boards over 20 inches long?

Any manufacturers offer an off the shelf vacuum type bare board loader that can handle boards 16"wide and 22"long? We're having issues with our de-stacker since these boards tend to come in warped.

I think as long as they are imported as different board numbers, you can have "duplicate" ref designators.

Baking before assembly does nothing good. It: * Increases costs. * Adds steps to the process and makes scheduling more cumbersome. * Increases the amount corrosion on solderable surfaces. We used to bake to remove the moisture from boards that caus

Hi, Does it really matter what temp the oven runs at as long as the PCB's are profiled correctly? I mean we run boards through all the time to check profiles, so as long as that's ok, would it matter what the oven though the temps where? Regards,

We had a build that showed a relatively high occurence of BGA voids like you were seeing. It was a very small volume first article that took a long time to get through the line so the paste sat on the boards too long. As we ramped up TACT time in p

Our solder ball problem is linked to moisture. If the paste sits on the board too long (especially during our humid summer months) we experience the problem. As far as the problem being specific to components or areas of the board, maybe some of th

What are the industry standards for eutectic solder-paste in conjunction with the life span of solder-paste. What is the recommended duration of solder-paste on a printed circuit board. Example: You print a board, how long can it sit before runnin

How long are the OSP boards out of there packaging? Is this a double sided smd process or single? Are the boards stored in nitrogen? Sounds like an osp issue to me!

I wonder if you could push this to exempt any board with SnPb paste applied to the entire board as long as it has fine pitch parts? hmmmmmmmmmmmmm
