How I can increase my PCB/product life up to 5 years for long term

ashutamar

I simply mean that how I can test and verify all the sections of my PCB like here I'm sharing PCB Schametic power section because main section is power section so let us know what things I should keep in mind and so on,

so main agenda is that here is the power section
and main loads are listed below

1 STM32F103C8T6 (max 20mA Current Consumption)
2 Digital 3 axis acc. STK8321. (1mA Current Consumption)
3 BLE PB3. (10mA Current Consumption)
4 4G A7672s Simcom module. ( Max 2A Current Consumption)
so just let us know all factors and things to make my pcb/product live long durability
like what kind of capacitor , ics , resgistor , pcb layout , and so on whatever you about it all you suggestion and guidance are welcome and appreciated
Thanks in advance image

  • This is a very broad question, it relies on years of education and experience, and books have been written on the topic, so I can't see that you can expect much from a few sentence comments.

    Why don't you justify your design to support your 5-year claim, put it in the body of the discussion or in comments, and then people here can see if your justification holds water, and offer their suggestions?

    I would say that whatever your design is, you'll soon know if it is realistic for 5 years of operation, when you have you justify your board in terms of any circuit, component, placement, and routing reviews that you will have to do in front of management and your peers. That will soon show up any issues! 

    If think that's not going to pass or it is too much pressure, then that is a clear sign it's not a design ready for prime time until you can justify your design to yourself before submitting your design.
