• PCB Design & Reverse Engineering

Our Engineer Team

Toptek PCB has a team of highly experienced and professional engineers, which includes five design engineers and nine R&D engineers. With over ten years of experience, we can provide professional support and services for your PCB design and reverse engineering needs.

PCB Design

PCB Design Core Flow:

  1. Preliminary Preparation: Draw the schematic diagram and prepare the component library (packages).
  2. Planning and Layer Stack-up: Determine the board outline size, number of layers (single-layer/double-layer/multi-layer), stack-up structure, and impedance requirements.
  3. Component Placement: Place components on the board, considering signal flow, heat dissipation (for high-heat components), and electromagnetic interference (separate high-frequency and low-frequency components). Components are typically placed from largest to smallest.
  4. Routing: Connect flying leads to actual copper traces, focusing on the width and routing of high-speed signal lines, power lines, and ground lines.
  5. Design Rule Check (DRC): Ensure the design complies with manufacturing process capabilities (trace width, spacing, vias).
  6. File Output: Generate Gerber files, drilling data, and a Bill of Materials (BOM) for prototyping.

Reverse Engineer

In simple terms, reverse engineering is the process of “disassembling and analyzing an existing product to figure out how it was made.”

Normally, building something involves: design blueprints → production → product.

Reverse engineering, on the other hand, involves: product → analysis and disassembly → logic/technical parameters/design blueprints.

Here are some of its main applications:
Software/Security:

Decompilation: Reconstructing source code logic by analyzing binary code (0s and 1s).

Uses: Finding vulnerabilities, analyzing malware, or achieving software compatibility (such as the famous Wine project).

Industrial/Mechanical:
Scanning and Reconstruction: Using a 3D scanner to obtain the dimensions of parts and generate CAD models.

Uses: Repairing discontinued parts or learning about competitors’ hardware structures.
