Composition and Applications of Double-Sided Printed Boards

Double-sided printed boards are typically made of epoxy glass cloth copper clad laminates, primarily used in communication electronic equipment, advanced instruments, and high-performance electronic computers.

Production Processes of Double-Sided Panels

The production process of double-sided panels generally falls into several types, including the process wire method, hole plugging method, masking method, and pattern plating-etching method. For double-sided PCB proofing, the most common process is the pattern plating-etching method. さらに, processes such as the rosin process, OSP process, gold-plating process, immersion gold, and silver-plating are applicable to double-sided boards.

Surface Finishing Processes

Spray Tin Process: Offers good appearance, silver-white pads, easy tinning, easy soldering, and low cost.
Sikkim Process: Known for stable quality, often used in IC bonding applications.

Differences Between Double-Sided and Single-Sided PCB Boards

The primary difference between a double-sided PCB board and a single-sided PCB board is that the single-sided PCB circuit is only on one side of the board, while the double-sided PCB circuit can be placed on both sides, with lines connected through vias. In addition to different production processes, double-sided PCB board production involves an extra copper sinking process, which facilitates double-sided circuit conductivity.
