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

We are facing lot of problems with tombstoning in 0201 components. Ironically tomstoning in these components is not occuring while reflow but it is happening when we subject them to thermal cycling test. We have been investigating the cause and thoug

Go to http://www.ipc.org and look up IPC-7351 - Generic Requirements for Surface Mount Land Pattern and Design Standard The successor to the IPC-SM-782A is here! The document covers land pattern design for all types of passive and active components

hello; When we are doing component land pattern design , one thing will always be in our mind; that is the basic criteria or common land pattern design guideline for reflow and flow solder assemblies. For basic fomula in calculating resistors are:

We're unclear about what you're seeking, but in order to move the conversation along, are you looking for: IPC-SM-782A - Surface Mount Design & Land Pattern Standard ANSI Approved Get up-to-date land pattern recommendations for ball grid array pac

Thanks for your input. What would you say is the biggest defect condition you see with 0402's? ANy difference with 0402 caps vs. resistors? Dan

The EIA does not provide that information. EIA standards focus on component dimensions. Alternately consider: ...cut... SM-782A - Surface Mount Design & Land Pattern Standard, Inc. Am. 1 & 2 ANSI Approved Get up-to-date land pattern recommendat
