If PCB board size is my constraint ....and I have designed my circuit ... 1. How to optimize the layout of design for smaller space? 2. How to run simulations if any to do intelligent SI test? Does packages by Cadence, Mentor support this kind of o

Can anyone recommend a good software package which can be used to create panel criteria from Gerber/Cad data. Needs to do more than step & repeat. Need to be able to define panel size, add panel fiducials, define breakaways and hole sizes, ability

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

Do any SMTneters out there have a good solution to substitute SMT parts that you are willing to share? I presume all of us have the issue where purchasing wants to buy "the same part" from a different vendor. While the part may be the same electrical

Profile should have a longer cool soak. Verify as was mentioned all pin/fixture support through out the entire process. Print, Place, pre reflow hand load, post reflow, carriers, ICT, Depanel and FCT. Conformal Coated or Potted? Mylars work well for

For package shapes/names I would recommend using manufacturer names. This is much safer than coming up with descriptive names like QFN32_5x5 as there are multiple 5mm 32Pin QFN shapes even when pitch is the same, this makes it safer to use a name in
