Use #FCBGA package to mount and test a #die
Not many, actually only a few, may have this issue. You get the die back but it is not packaged yet. How to put it on pcb board to test?
In old days, a small pcb board is designed. Mount die on this small board and then mount the latter on the…[Read more]
#Crystal osc circuit chip internal drive strength adjust
A typical #xtal osc is shown. Two caps and xtal are external to chip. The op amp is inside chip. To board designers, that op amp driving strength is not fixed. They normally have higher driving strength at bootup to make sure xtal…[Read more]
Another reason to use 3.3k-10k for pull up
3.3-10k is normally used for pull up. Main reason is RC rise time. Another consideration is chip internal pull up/down. They are normally around 50k but with big variation. Sure they can be turned off later by fw to avoid conflict of board pull…[Read more]

[Video] Use MG Hyperlynx for board power integrity and thermal simulation
Short 6 minute video and right on the point. It shows how easy to analyze thermal and power integrity issue such as current density and their effects on board temp distribution.

IO Pad Checking with IV Curve
Debugged a chip and one of its IO was not functioning. We suspected IO pad might be burned. So we used IV curve tracer to get this IO’s IV curve. It came back as the graph shown. Turned out this kind of waveform was expected. The ESD protection window defines…[Read more]
A short video demo about using HyperLynx to analyze SI and COM of multi-Gb/s serial channel
Doing high speed board design these days. See this video online. Though it could be useful to others too.
