Charlie- You answered your own question...1206, 0201, 0603, 0805, 0402 are all the package dimensions. In addition Here is a generic link from practical components that list most package sizes, feeder size, tape type... http://www.practicalcomponen

Hi, Does anyone have any experience of setting up FMEA's for automotive customers? We have a batch to run for a customer and are looking into the FMEA's at the moment. It seems that the FMEA should be done each time a product is introduced, I th

I am forced to use fine pitch parts in a new design. Board alignment in production has to be addressed. Fudicals, where to place, shape, size. I'm assuming they must be in the copper to represent the pad positions. Are they placement machine depe

Is it possible that the PCB is moving? First try an autoscan of the fids and then immediately perform a manual trim which will bring the camera over to where it found the fid. If it is on, there is an offset drift in your axis or the PCB is able to m

Have any of you ever worked with Actel's QFN 180? A three row I/O QFN? Actel has a published paper on design and assembly guidelines, but we're finding that they are pretty much generic, and don't really work as well as they lead you to believe. ht

And making a form with drawings of generic parts with blanks to fill in the data can help streamline the process as well. Has anyone met anyone who trusts datasheets more than the part itself? I always figured that the machine was verifying the par

If you failed math like I did. A 0.005 inch stencil would work fine for those parts. Most stencils are 0.004in for fine pitch 1005s 201s. 0.005in is probably the most common generic stencil. 0.006in generally is if you need extra solder for big parts

We have the same magazine-loaders. It´s not possible to stop the bottom conveyor. It`s hardcoded in the plc , you have to modify the plc-program to change this functionality. The instruction-manuals are also not generic as there are some different ve

Thanks for the reply, how do people handle different packages then if you can't add new ones? If we had a 1206 sized inductor, then a 1206 sized ferrite bead and so on, they would all have to be grouped under the same generic heading? e.g. Chip-R321

If you have some budget left over from buying the machine, contact the guys at Pentagon EMS. They build a bullet-proof wave pallet. They can make a board specific, for each assembly, or a generic-adjustable one that can be used for most boards. I can
