Hi Anne, I believe what your customer is referring to is a thick film hybrid. It's similar to chip-on-board, except the substrate is usually alumina (a ceramic) and the conductors and dielectrics are screened on a layer at a time. The term thick film differentiates this technology from thin film, where the conductors are "sputtered" on in a vacuum deposition process, as when making an IC.
