Пост в рассылке eagle.support:
My company has fairly recently purchased Eagle (it's a Friday night, and I
don't have the license info on me atm - I can get it Monday if you require).
I'd just like to share an experience with you.
We just created a fairly small PCB, with quite a few surface mount
components crammed into a small area. I go to power it on, smoke comes out.
After several hours it turns out that the pinout of one of the components in
the eagle libraries is incorrect (MAX660CPASM). This is a simple 8 pin
chip - but pins were around the wrong way. The net result is about 600
dollars worth of useless circuit boards.
I swore a lot, then kicked myself for not checking all the pinouts properly.
For revision 2, I use a corrected pinout for that chip, but introduce a new
chip - the INA2126. I checked and double checked to make sure the pinout was
correct.
Today I got the boards back. I've just realised that the footprint is for a
wide SO16, and TI don't sell such a beast. I don't think they ever have. All
they have are narrow SO16 devices. So I have another batch of useless
circuit boards.
I have to ask: Does anyone at Cadsoft actually try these libraries? Or at
least double check them compared to the datasheets? I hope that they are not
uploaded by users, then added to the next version of Eagle without being
double checked.
Для тех, кто в английском не силен : сделал чувак маленькую платку, на ней MAX660, взятый из стандартной библиотеки Eagle. Плат таких сделали на 600 баксов (вот идиоты
). Включили - она задымилась. Оказалось что в библиотеке неправильная распиновка. 600 долларов на ветер. Сделали еще партию плат, на них INA2126. Стали монтировать - а корпус микрухи уже чем посадочное место на плате. У TI ваще нет микросхем в таких корпусах.
Мораль - проверяйте компоненты которые берете из тех библиотек, которые не сами сделали. Да и которые сами сделали тоже проверяйте
