I made my prototype board using the nrf51822 chip. for this prototype i use an on-board connector + external programmer to flash the nrf51822 chip.
that's work fine but i'm planning to make a big run of 1000 beacon boards. i don't think i'll make the flashing of each nrf chip the same way as i made for the prototype. it's annoying to do the programming of each chip apart and it will take a lot of time.
So i want to know how the professional industry flashes their devices like nrf or any other microcontorllers for big run ?
did nordicsemi sell a flashed nrf chip? meaning i give him my program and they provide me for example 1000 nrf chip with the program already installed in the memory chip ?
waiting for your helpful propositions.
My experience with external flash is that you can have the distributor program them for you (for a small fee) in advance of assembly. I've not yet tried this with an embedded flash device, but I expect it's possible. Check with your distributor to see what options they offer.
Look in the "Blogs" sidebar on the right, and you will see HI-LO Electronics pushing their services for this.
Buying pre-programmed chips directly from Nordic is not possible as it would be too much logistics to manage customer software at our production facilities. Therefore, the manufacturer has to take care of the programming and can e.g. use jigs and programmers from Elnec or Segger for quick batch programming. There are also dedicated programming houses like Arrow that specializes in pre-programming. You can also contact some of our distributors and ask them if they can help you out.
There are also already a few posts here on devzone discussing fabrication: 1 & 2.
I introduce you a mass production solution for nRF5x.
Mobilian developed a JTAG multiplexer board and control program.
You can program max 8-ports separately with internal J-Link.
Also you can manage project based program for SoftDevice, Program and Bootloader.

I hope this brand new solution may helpful.
