Abstract:
A method of fabricating printed circuit boards integrating thick film resistor components and thin film circuit portions thereon is disclosed. This is a two-phase process, where the first phase is to create multiple thick film resistors, and the second phase is to create a thin film circuit portion on the substrate with thick film resistors in existence, involving the printing of the electrodes and the resistive coating for the thick film resistors, and the printing of a low temperature passivation layer over the resistors; and the thin film circuit is formed by titanium and copper layers over the substrate, and electroplating of interconnections to form copper plated circuit. The present fabrication process does not require drilling of holes nor electroplating of leads to the resistors, thus the whole process can be automated to a greater extent than with conventional techniques.

Abstract:
A package carrier has multiple ceramic substrates and a frame with a polymid tape. The frame has multiple through holes for receiving the ceramic substrates. The ceramic substrates are packaged with chips. The frame is made of plastic so the package carrier can be easily cut to separate individual electronic devices. The present invention combines individual ceramic substrates with the plastic frame so the cutting time can be reduced and the quantity of electronic devices fabricated is increased.

Abstract:
A method for fabricating high integration multi-layer DPC lines on a ceramic board is to make the high density of multi-layer metal lines with insulating layer and the fine through holes. The metal lines are able to form in the different insulating layers, so as to the density of the metal lines is high. Besides the through holes defined in the ceramic board are fine, so that the space where the metal lines formed on is larger than the normal. Thus the fine through holes are stuffed with the conductive material, so that the quantity of the inductor of the metal lines is as possible as decreasing.
