Our R&D uses Land Pattern Design based on Manufacturer's recommendation and not IPC Standard Land Pattern design. I suggested to shift to IPC but he just ignored me and laughed about it. We are encountering hips of wrong land pattern design since we

| Need a footpint for a 10 lead uSOIC (RM-10) | Have you tried the IPC website at www.ipc.com, they have an online land pattern calculator that not only gives you there RLP (Regisistered Land Patterns) for standard components, but also allows you to

| What to look for that causes tombstoning and the corective action. | Check your land-patterns. If they do not meet IPC standards, change your CAD libraries to IPC (or some other industry accepted standards such as SMTPLUS). If you have "home-gr

I have seen people take old stencils and cut out land patterns, place the component over the land pattern and use a orange stick to move the leads back into place.

Unfortunatly there is no land pattern in the component datasheet beside i am not fan of the land pattern recommendation from datasheet.

Greetings: I would like to know the common land patterns and aperture shapes that are currently in use. We are doing some research on the same. Please respond to the thread if you have a success story with you current design. Thanks KT

FYI: IPC-SM-782 has been superseded by IPC-7351A, IPC-SM-782 land patterns previously found under the "Manufacturer Part Number" database portion of SM-782 Land Pattern Calculator are no longer maintained by IPC.

Hi! Can anyone tell me what is the min spacing between PCB edge & land pattern to avoid cracking of components due to mechanical stresses caused while depaneling with cookie/pizza cutter. Thnx!
