During the process of PCB design and PCB manufacturing, our company adopts a series of systematic methods to ensure that each link can achieve high standards of quality and efficiency.

PCB Design Process

Requirement Analysis

Before the PCB electronic board assembly design begins, we first communicate with customers to understand the functional requirements, performance indicators and physical dimensions of their products. This step ensures that we can tailor the PCB design for our customers.

Schematic Design

Engineers use professional PCB design software to create a schematic diagram of the circuit to clarify the function of the circuit and the placement of components. The accuracy of the schematic is crucial for subsequent PCB manufacturing.

Layout Planning

After the schematic is completed, we carry out PCB layout planning. This includes considering factors such as signal flow, electromagnetic compatibility, thermal management, and power distribution to optimize the performance of the circuit board.

Design Rule Checking

We use automated tools to check whether the design meets specific design rules, including trace width, spacing, etc., to ensure that the design meets manufacturing and electrical specifications.

Signal and Thermal Analysis

Signal integrity analysis and thermal analysis are performed through simulation software to ensure that the PCB can work stably under high load.

Output photolithography file

Finally, we convert the design into a photolithography file, which directly affects the quality and accuracy of the subsequent photolithography process.

PCB Manufacturing Process

Material Selection

We select the appropriate substrate material and copper foil thickness according to the design requirements to ensure the current carrying capacity and signal transmission quality of the circuit.

Photolithography process

The circuit pattern is transferred to the copper foil using a high-precision photolithography machine to ensure the clarity and accuracy of the pattern.

Chemical Etching

The required circuit pattern is formed by precisely controlling the etching time and removing the excess copper foil.

Drilling and Metallization

Accurately drill holes to facilitate component installation and circuit connection, and perform hole metallization to ensure the reliability of electrical connection.

Electrical Testing

After manufacturing is completed, we conduct electrical testing to ensure that each PCB meets the design requirements and can work properly.

Quality Control

Throughout the entire PCB electronic board assembly production process, we implement strict quality control measures to ensure that each link meets industry standards.

Through a systematic PCB design and manufacturing process, our company is able to provide high-quality PCB electronic board assembly to meet the various needs of our customers. Whether it is preliminary design or large-scale production, we are committed to ensuring the success of each project.
