An integrated compound nano probe card is disclosed to include a substrate layer having a front side and a back side, and compound probe pins arranged in the substrate layer. Each compound probe pin has a bundle of aligned parallel nanotubes/nanorods and a bonding material bonded to the bundle of aligned parallel nanotubes/nanorods and filled in gaps in the nanotubes/nanorods. Each compound probe pin has a base end exposed on the back side of the substrate layer and a distal end spaced above the front side of the substrate layer.

An improved plating method in combination with a low-temperature thermal treatment is disclosed. The method for reducing the stress in the nickel-based alloy plating comprises the steps of: (a) adding ceramic particles into a plating bath containing soluble nickel salts; and (b) placing a substrate in the plating bath and thereafter carrying out a pulse-current electroplating in the plating bath. The method of this invention can prevent substrate softening or deformation problems. The use of a post low-temperature thermal treatment can slightly increase the hardness of the coating products. The use of the low-temperature thermal treatment can reduce the stress of the coatings since the hydrogen embrittlement resulting from exist of hydrogen in the coatings is eliminated.

An optical fiber alignment element using integrated micro ball lens includes a substrate and a plurality of V-shaped grooves or waveguides formed on the substrate by lithography and etching. The substrate surface is coated with a first polymer layer and a high transparency second polymer layer, then is processed through a lithography process and heating process to form at least a base pad and a spherical micro ball lens between the V-shaped grooves or waveguides. Then dispose optical fibers in the V-shaped grooves. And encase an upper cap over the micro ball lens, grooves, and optical fibers or waveguides. Through suitable configuration and positioning of the micro ball lens, grooves or waveguides, the micro ball lens may be aligned precisely between two sides of the optical fibers or waveguides. The process is simpler, more accurate, and may produce the optical fiber alignment element in an integrated and batch fashion.

The present invention is related to a method for manufacturing lead frames and a lead frame material including an intermediate layer and a top layer. The intermediate layer is composed of a layer of nickel-cobalt alloy having 5 to 30 wt. % of cobalt and a thickness of 3 to 20 microinches and a layer of nickel or nickel alloy having a thickness of 10 to 80 microinches. The intermediate layer can inhibit the diffusion of the base metal to the surface of the leads. The top layer consisting of gold or gold alloy, which is composed of gold and at least one metal selected from the group consisting of palladium, silver, tin and copper and has at least 60 weight percent gold, has a thickness of 0.1 to 5 microinches.
