About as good as you are going to get for a general (broad) package download is from the two dummy component companies listed. If you want something better and corresponds to the parts that you are using (not dummy parts) download the data sheets fo

Yes, you can ask for scrap boards, buy Dummy boards/parts or engineer off past runs. For this cost, I would profile, profile, profile. I would make/buy a dummy board. If you don't have one this thick, glue/ adhesive/ bolt some scrap boards togeth

Looking for some welcome advise again folks. We are currently using a reflow profiling software package which requires passing a data logging unit through the oven attached via thermocouples to a populated 'dummy' PCB. The problem is we have a very

Mohammed: Huuumm, identifying components, sounds like a dangerous thing to do, if you�re in the assembly business. ;^) Try: � "Component Identification Desk Reference Manual", with an IPC ordering code of DRM-18. This book is not a standard, but

Hi all, There seems to be a problem with the major component vendors/manufacturer everywhere; to supply lead free dummy/daisy chain components, in particular BGA-devices, within a reasonable time (not a big fan of 8-12 weeks). If they got them at all

Just for your reference. If you need to check for surface contamination, then we shall go for microscope inspection at different modes. But this will not reflect on actual PCB performance. Solderability test will still a good option if PCBA is expe

Robert: Consider requesting samples of different sized solder balls from a variety of suppliers, solder them to dummy boards, and compare the size of reflowed balls to your spec. Then you could buy based on results. My2� Dave F

does anyone know of a book that contains the measurements of most of the surface mount components used today.is there a library that can tell me x,y,z,lead length and width and foot length.lead pitch.ect.dummy component catalogs only go so far.

There's a board called "SMTA Saber Board" that I have used. It has several different components types and is good in evaluating lots of different process equipment. This can be purchased from any of the "dummy" component companies.....
