Liquid crystal polymer (LCP) is used as substrate and Copper (Cu) as metallization thin film.
Comparison of the areas revealed identical peaks for iron and calcium, likely from the plaster substrate, and copper.
In order to resolve the parasitic capacitance by the air bubbles between the PI substrate and copper tape, the transmission line with the ground layer of the silver paste is additionally fabricated, as shown in Fig. 3c.
This paper has presented transparent conductor oxide materials (TCOMs) based microstrip patch antennas with glass substrate and copper ground plane, which have been deeply analyzed in the visible spectrum region in comparison with the practical patch antenna model of indium tin oxide patch with glass substrate and different TCOMs based ground plane.
Detection of the deposited biotinylated tyramine and visualised via a streptavidin-peroxidase conjugate with 3, 3-diaminobenzidine tetrahydrochloride (DAB) substrate and copper enhancement giving a brown coloured end product All slides were counterstained in haematoxylin, before manual dehydration through alcohols, clearing in xylene and mounting in DPX.
Copper thin films were prepared by a metal organic chemical vapor deposition technology on top of TiN/Si substrates, and the films were examined by varying the experimental substrate temperature and copper source vapor pressure.
In the same year, Shibata and co-workers reported fluorination of similar substrates using nickel and copper complexes of 37 (Scheme 11), with the use of MTBE as solvent leading to higher enantioselectivies.
The contact area between the substrate and molten copper was reduced by these protrusions.
The adhesion strength between TESPA SAM-coated epoxy resin and ELD copper film was up to 13.8 MPa, which could satisfy the purpose of TESPA SAM as adhesion enhancer and diffusion barrier layer, while the adhesion strength between non-TESPA-treated substrate and ELD copper film was only 1.2 MPa.
Breakage of the solder masks from the substrate base material and copper base layer exhibits the same pull-off strength values if the interface glass fiber/epoxy resin within the base material is not affected.
