PLCC Land Pattern specs, SM-782A | 23 May, 2000

I am a PCB Designer / Mech. Engineer for a telecom company that has just started. What I would like, if possible is a reference copy of the SM-782A IPC spec. or some input on a way to calculate depending on the PLCC part dimensions, land pattern creation.

We currently do not have IPC Standards, YET. But were are working on it. Any help would be greatly appreciated.

Thanks,

Hi Brett,

we like designer who care about pad design, welcome on board. Go to the IPC-homepage under www.ipc.org. There you find the information how to order IPC-documents, you don�t have to be a member to get them. Also you can find an online landpattern-calculator (online resources and databases) but I have to admit that having the IPC is a great help using it, so you should get yourself a copy asap.

good luck

Wolfgang

I second Wolfgang. Welcome, It's good to hear from someone who wants to design something we can build. Another useful resource is the land pattern book from SMT Plus www.smtplus.com 831/438-6116 Also useful are the component mechanicals available (free) from JEDEC as publication 95 www.jedec.org Of course, as a final reality check for a new component, nothing beats having the actual part. Good luck. John Thorup
