What is a typical SMT placement defect rate?

Electronics Forum | Thu Jul 10 08:18:15 EDT 2014 | emeto

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

I am seeing a similar problem. We are using Orbotech AOI. I am trying to find a way to make the light source brighter.

Please us OK/NG light. This is advace light.Especially when there are 402 black resistors and they are on dark green or balck pcb, this ligt is perfect. But, this is optional thing. You must contact with local distributor to activate this ligt.

I have seen it all. from OEM that has 12 assemblies and the setup is always on the machine to a 5-6 setups a day in a CM environment with small quantities.

Thanks Mac! I have been doing a lot of reading and I think I understand me challenge ahead of me. I do however have a double sided assembly and the BGA's are on the second side. So I know I have to make this a quick build…. June
