What industry standard applies to a pad/part size mismatch?
It's a wonder pad to part size mismatch doesn't happen more often, considering the thousands and thousands of opportunities on assemblies.
When it does happen, it's a big problem. Try as hard as we might to read a solution into the IPC specs, it's not always simple. This feature takes you through a common pad component mismatch and the detailed solution ...

Many were large, some small, but all had various means of delivering hot air to the component with varying degrees of process control.
Despite their diversity, they all had one thing in common -- they were fine for removing components from a circuit board, but none were particularly good at the component replacement process ...
