Is it a good idea to powering my prototype PCB by onboard regulator or external supply? Herhangi bir ipucu?

I'm laying out my PCB for the first prototype of my project. The board is relatively simple. I am now thinking of laying out the power section but am wondering if I should just power it from an external supply.

Evet, you can lay out an external power section with a nice meaty capacitor. It saves picking a VReg. Tips are as follows.

Over-spec the regulator for external power, so you don’t have to worry about the power requirements changing.
If you are involving high voltages, keeping it away from the main board is best. It is quite common for the power supply portion to be on a separate board anyway – makes for a more modular system that is easier to design or redesign.

Why does the manufacturer use a flying probe tester when they already have an in-circuit tester?

Geçen hafta, I visit a PCBA manufacturer for our new project. Sadece devre içi test cihazını değil aynı zamanda uçan prob test cihazını da tanıtıyorlar, her ikisi de kalite seviyesini sağlayabilir. Yani, Why does the manufacturer use a flying probe tester when they already have an in-circuit tester?

Why aren’t components in DIP package shipped with straight pins?

I’ve noticed that all DIP packaged devices have pins which are at an angle other than 90∘ and need to be bent so that the angle is right for insertion into holes on the PCB or wherever. Is there any reason other than tradition for that?

Are surface mount or through hole connections more reliable for safety critical applications?

Factors like safety certifications and margins of error are more important when it comes to safety critical applications, Örneğin. havacılık. Lots of content online have showed the pro and cons of SMT and THT. But is there a straight-forward winner between these two?
