Possibility of a cheaper pick and place machine design?

@Comatose You answered all my question about the board and operator costs, and I'm getting a good idea of how the numbers look like.

My gut feeling is that I should do more than just post it here... the suggestion will ultimately be forgotten. Does anyone know where on the internet I should actually post something like this?

Why use magnets? I found a KS project of a pcb prototyping machine that uses vacuum for PnP. Here is a video https://www.kickstarter.com/projects/botfactory/squink-the-personal-electronic-circuit-factory/posts/929661

Padded static bags.

Does anyone have any experience with using padded static bags to minimize damage to boards during handling and storage? Does anyone recommend a specific brand or type?

We buy padded bags from ULINE. They work well and are self sealing also, we reuse so we don't seal them. They come in a wide array of sizes as well.

Is there anyone actively splicing reels at the pick and place machines with success ? What type of splice tool are you using ? Any input regarding splicing appreciated. Regards, Sr.

What is a typical SMT placement defect rate?

I think what you are asking for is called First Pass Yield and for us that is in the upper 90s. It will depend on the board complexity and quantity - makes big difference if you run 10pcs or a 10000pcs. Regards, Emil

Hi, If you are working in high mix low volume, your machine time is very expansive. In this case you must rely on the programmer, people experience, and make preparations offline (like Setup etc.), so do not hold the line in vain. Best Regards, Ale

Removing oil from compressed air

Electronics Forum | Thu Jul 10 09:41:37 EDT 2014 | bobpan

Can anyone recommend a top notch filter to remove oil from the compressed air lines. The filter will be placed before the machine. We have traps that catch .01 micron oil in the airline but it is still getting through to the machine. Thanks, Bob
