Imterface Board – System Testing Aid

Our interface board was created for Jaguar Land Rover (JLR). The product was produced in a relatively small batch, and the project included:

  • Incorporation of SMT sockets

  • PCB assembly – through-hole soldering

  • The final assembly of the switches and display unit

  • A functional test
