A bending apparatus includes a fixing structure, a first driving mechanism, a first pressing head connected to the first driving mechanism, a second driving mechanism and a second pressing head connected to the second driving mechanism. The first driving mechanism is configured to drive the first pressing head to move onto a first surface of a first portion, and to drive the first pressing head to push the first portion to rotate to a first side of a body portion, so that the first portion is parallel or substantially parallel to the body portion. The second driving mechanism is configured to drive the second pressing head to move onto a second surface of a second portion, and is further configured to drive the second pressing head to pull the second portion to rotate to the first side of the body portion while the first pressing head pushes the first portion.

A printed circuit board, and a method of fabricating the printed circuit board is disclosed. The printed circuit board includes at least one coaxial via. A hollow via is disposed in the printed circuit board. A metal sleeve is formed around the circumference of said hollow via. An inner conductive path is disposed in the hollow via. Additionally, an insulating material is disposed in the hollow via, between the conducting path and the metal sleeve. The conductive path is used to connect signal traces disposed on two different layers of the printed circuit board. In some embodiments, these signal traces carry signals having a frequency above 1 GHz, although the disclosure is not limited to this embodiment.

A substrate package includes a woven fabric having electrically non-conductive strands woven between electrically conductive strands including wire strands, co-axial strands, and/or an inductor pattern of strands. The package may be formed by an inexpensive and high throughput process that first weaves the non-conductive strands (e.g., glass) between the conductive strands to form a circuit board pattern of conductive strands in a woven fabric. Next, the woven fabric is impregnated with a resin material to form an impregnated fabric, which is then cured to form a cured fabric. The upper and lower surfaces of the cured fabric are subsequently planarized. Planarizing segments and exposes ends of the wire, co-axial, and inductor pattern strands. Since the conductive strands were formed integrally within the planarized woven fabric, the substrate has a high mechanical stability and provides conductor strand based electrical components built in situ in the substrate package.

A soldering system for processing at least one printed circuit board. The system comprises a first solder pot and a second solder pot, each configured to move within a movement plane. At least one of the first solder pot and the second solder pot is further configured to rotate about a solder pot axis extending transverse to the movement plane. The first solder pot and the second solder pot can be moved relative to the at least one printed circuit board, and at least one of the first solder pot and the second solder pot can be rotated about its solder pot axis relative to the at least one printed circuit board, to simultaneously process the at least one printed circuit board using both solder pots. The soldering system may thus be used to process either a single printed circuit board with both solder pots simultaneously or a pair of printed circuit boards simultaneously with each solder pot processing one of the pair of printed circuit boards. A corresponding soldering method is also disclosed.
