Hi guys,
I would like to share with you my very bad experience in order to help you to avoid becoming completely depressed as I am now Ive been working about 50 hours on a PCB using Kicad and the libraries found on the soundforge. Ive a TFQP microcontroller in my design and used the module found in microchip-2 library called TQFP64 ! Ive not checked before drawing the PCB that the module was ok . And what a mistake ! The module is wrong, dimensions are not correct making the component impossible to mount and solder ! I can of course correct this by changing the module, but using Kicad this means erasing all the wires connected there and restart most of my design (very compact). I think about 20h more to spend on this PCB That is absolutely dramatic for a professional use as spending 70h on a such basic PCB with around 100 components ! So my best advice is to redesign all your modules and not spend one minute using the libs you can find in Kicad or on the web. There are so many errors that you discover all along your design (silkcreens, wrong dimensions, ) making finally a massive waste of time. Of course, If I knew that before I would have redesigned all the components and created my own libs Hoping it will prevent some other people to face what Im facing now ! Best Stephane
