Job ID: 34934523

Budget: $2 – $8 USD

Hello
I need a crash course from someone with a very good knowledge on electronics circuit design especially for devices that is used in camera system and more specific the camera flashing device.

How different high voltage camera flash circuit design looks like? and how the circuit works?
How to design a suitable pcb layout that can cool the high temperature that it is create from the high voltage flash?

The prefered material are reference designs that include circuit design and layout design.
Close example on reference design
