Abstract: A process for infrared spectroscopic monitoring of insitu compositional changes in a polymeric material comprises the steps of providing an elongated infrared radiation transmitting fiber that has a transmission portion and a sensor portion, embedding the sensor portion in the polymeric material to be monitored, subjecting the polymeric material to a processing sequence, applying a beam of infrared radiation to the fiber for transmission through the transmitting portion to the sensor portion for modification as a function of properties of the polymeric material, monitoring the modified infrared radiation spectra as the polymeric material is being subjected to the processing sequence to obtain kinetic data on changes in the polymeric material during the processing sequence, and adjusting the processing sequence as a function of the kinetic data provided by the modified infrared radiation spectra information.

Abstract: The present invention is directed to the use of ordered polymers as a substrate material for the preparation of printed wire boards (PWB). In preferred embodiments, the PWB of the present invention comprises a generic, high density, organic multilayer PWB capable of being employed as a high density leadless perimeter and in grid array ceramic chip packages. Specific chip package density requirements are 0.020-in. centers with up to 300 input/outputs (I/Os) for perimeter type packages and 0.050-in. center grid array type packages with up to 240 I/Os per device. In its most preferred embodiments, the present invention is directed to a method of forming a PBT PWB substrate layer of 0.0025 in. or less in thickness. Another preferred aspect of the present invention concerns the discovery that a copper layer can be bonded to a PBT film substrate with a strength comparable to existing PWB materials.
