We have Quins Professional in use which is quite handy for first article/piece inspection. You can easily compare assembled board to the pick&place file and placement drawings.

At an EMS I used to work for, our process for first article inspection was to have a human technician do a point to point comparison between the BOM and the PCB. They would verify component part #s were correct per the location, correct polarity and

Hi All, Anyone want to talk about how do you did the 1st sample inspection in your SMT department? I mean once you want to produce a new product. After the material on board, and before mass production, we always need to do 1 or 2 sample to test if a

Here, there are two possibilities - either it is a new board to us (ie built elsewhere previously) or it is a new product for the company requesting the build. If new to us only, ask for a sample PCB. You will need CAD data for pick & place machines

Hey SWAG- Not an uncommon scenario where I'm at. But the bottom line is, as others have said: Profile, profile, profile. Here, we have dedicated profile boards for each product we build and in most cases they're EXACT representations (my library i

Thanks, rywman. I do have a solder sample along with dummy BGA's so we should have what we need. This BGA is actually 1152 pins (I didn't have that right in my original post). The bad part is that we are building only one board only and the actua

Thanks for the info. I have looked at an EVA mesh that will pass esd test as well as exposure to w/s flux and hot water. Stainless is great but the the softer material is what I want. I want to get samples of the thermoplastics from Mcmaster. Thanks

Can you provide sample images to understand it in detail? It will give better idea about your explanation. http://www.7pcb.com
