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.
