Abstract: Methods, systems, and apparatuses for multichannel, matrix-based testing of electrochemical materials are described herein. The system provides an electrochemical testing apparatus that consists of a bottom block having a first array of N×M receiving wells, and a top block with a second array of N×M chambers, with each of the N×M chambers having an electrical connector. The method involves inserting, into a number of the first array of N×M receiving wells, one or more electrochemical compositions to be tested. The method then involves closing the top block onto the bottom block. When the top and bottom blocks are closed, the N×M receiving wells and N×M chambers are aligned, thereby forming N×M testing cells. Finally, the method involves measuring one or more properties of the electrochemical composition inserted in the plurality of the N×M receiving wells.

Abstract: A metal-resin composite, a surface treatment method, and a substrate of a printed circuit board (PCB) for high-frequency and high-speed signal transmission comprise a surface-treated metal, and the surface-treated metal includes a nano-scale pore array that is used for filling of a resin and vertically extends from a surface to an interior of a metal, where nano-scale pillars are provided to extend from bottoms to openings of nano-scale pores of the nano-scale pore array. The pillar-in-pore structure makes a resin entering a nano-scale pore have an ultra-high anchoring effect on a resin body outside the nano-scale pore. Therefore, on the premise of not using an additive such as a T liquid or a coupling agent, the present disclosure greatly improves a tensile bonding strength at an interface between a resin body and a metal substrate, and also eliminates a decline in an interfacial bonding strength of a composite.
