Hi all, this is a rage post about Bottom View in datasheets.
Over the past 2 years I have probably lost around $7000-10000 and weeks of development time due to datasheets using Bottom View for their pinouts. They do this, I am distracted and fail to notice,
it gets through design review unnoticed, and the result is a PCB with mirrored footprints and a total disaster.
Yesterday I assembled and started testing a 30W power supply I designed for use with a radar system computer. And guess what? Some of the MOSFETs were mirrored! With the result that the power supply shorted out!
I have complained about this before to companies, and they have actually updated and fixed their datasheets in response. So people understand that Bottom View is a mistake.
I know a lot of industry people are here on EEVBlog. I hope you will have a conversation with whoever reviews datasheets at your company, and a rule is put in place that Bottom View is
never tolerated.
It would also be great if we could start posting links to datasheets here, whenever we encounter Bottom View. To call some attention to this very real and frustrating problem!
Parts with bottom view problems!
