A printed circuit board and a forming method for forming the printed circuit board are disclosed. The printed circuit board includes a substrate and a conductive layer. The substrate includes a through hole, wherein one side of the through hole of the substrate corresponds to a first diameter, and the other side of the through hole of the substrate corresponds to a second diameter. The second diameter is greater than the first diameter. The conductive layer is placed on the inner surface of the through hole for electrically connecting the two sides of the substrate.

Printed circuit board and forming method thereof

A printed circuit board for avoiding producing burrs, the printed circuit board includes a packaging substrate, at least one plated through hole, at least one first conductive portion, at least one non-conductive portion, at least one second conductive portion and at least one cut section. The plated through hole is formed on the packaging substrate. The first conductive portion and the second conductive portion respectively are adjacent to two sides of a peripheral of the plated through hole and separated by the non-conductive portion. Furthermore, the cut section is arranged on the non-conductive portion, thus the packaging substrate is cut without passing through the first conductive portion, and it will not cause the burrs on the first conductive portion.

Printed circuit board for avoiding producing cutting burrs

A method for producing a positive electrode material adapted to the Li-ion secondary batteries is disclosed. The produced material has the following formula (I),LiMnMO&#x2003;&#x2003;(I)wherein M is Mg, Al, Cr, Fe, Co, or Ni; 0&#x2266;x&#x2266;0.4, and 0&#x2266;y&#x2266;0.2. The method is achieved by co-precipitating a gel salts with an organic acid. First, salts of Li, Mn and M are mixed with at least a solvent to form an initial solution. The mole ratio of Li, Mn and M ions in their respective salts is (1+x):(2&#x2212;y):y. Next, at least a chelate is added into the initial solution to form a suspension, which is then filtered to obtain a co-precipitate. Finally, the co-precipitate is calcined and heated to obtain the final product.

Method for producing positive electrode material of Li-ion secondary battery

A metal-air fuel cell includes an anode and a cathode with an electrolyte between the anode and the cathode. The anode includes a plate-like body made of a composite anode plate including a reaction layer, a reaction-enhancing layer and a collector layer. A plurality of fins are formed on and extending from a surface of the anode plate. A plurality of openings are selectively defined in the anode plate in correspondence to the fins. The fins are arranged in an array with fins in adjacent rows aligned with each other or offset with respect to each other. The anode plate further includes a plurality of openings corresponding to each fin.
