Can we use SMD Machines for printing inks on flexible PCB? (There is a FPC with four layer printed ink) I attached a picture of my board.

Hello, does anyone know if there is an IPC standard for carbon ink? we use for keypads instead ENIG, we found batchs of PCB with 2-3ohm, 20ohm, until 300ohm( resistance of contact surface) by the same PCB supplier!

We are considering converting from a water wash wave solder porcess of carbon ink touch pad buttons to a no-clean process. Since the carbon ink buttons are exposed to the molten solder, we are concerned about the residue that is left behind from the

In a typical flowline assembly of circuit boards, what are the different methods used for tracking WIP ? I can think of : 1. travel cards - not suitable for panelised boards 2. Marking ID# on board at various operations while board is being built.
