integrated circuit - PCB fabrication vs PCB assembly


What is the difference between PCB fabrication and assembly? Some companies like Golden Phoenix list that based on the size of PCB, it outputs a quote.


Mine was 2.1 x 1.6 inch. It outputted 29 pieces for $100. So it means if I give them my schematic and PCB layout and pay them $100, I will get 29 pieces of production-ready PCBs ready to sell?


Now one company, EPS, lists fabrication and assembly differently. In assembly, it states I ought to provide the parts. In fabrication, anything but about parts is stated.


So what are these companies suggesting?



Answer



In PCB world, "fabrication" refers to making the printed circuit board and nothing more. "Assembly" means soldering on all the parts.



So, in your example, $100 will get you 29 pieces of copper-clad FR4, with traces etched and holes drilled. It is up to you to solder on the resistors, capacitors, etc which you need.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
