The manufacturing of ultra-thin BT PCB starts with material selection and preparation. BT resin as a substrate material needs to undergo strict screening and inspection to ensure its quality and stability. In addition, as the main material of the printed circuit board, the material of the conductive layer also needs to be carefully selected to ensure good conductive performance and reliability.

After the materials are determined, it’s the design and layout stage. Designers need to accurately draw PCB wiring diagrams and component layout diagrams based on customer requirements and product functional requirements. Due to the special requirements of ultra-thin BT PCB, designers need to pay special attention to the density of circuits and the compactness of traces to ensure the best circuit layout in a limited space.

Once the design is completed, it enters the graphic imaging stage. This stage mainly converts the designed circuit diagram into actual graphic images, which is usually completed through computer-aided design (CAD) software. During this process, designers need to carefully check the location and connection of each component to ensure there are no errors or omissions.

After completing the graphic imaging, the next step is the printed circuit layer. This step is to print the designed graphic image onto the BT resin substrate to form a circuit connection pattern. During the printing process, printing accuracy and quality need to be ensured to ensure the smooth progress of subsequent processes.

After the printed circuit layer is completed, it is the chemical etching and cleaning stage. In the chemical etching process, a specific chemical solution is used to etch away the unwanted copper foil, leaving the desired circuit pattern. After etching is completed, thorough cleaning is required to remove the residue generated during the etching process and ensure that the board surface is clean.

After cleaning is completed, the drilling and plating stages follow. At this stage, drilling equipment needs to be used to drill component mounting holes and connection holes, and surface plating is performed to increase the conductivity and corrosion resistance of circuit connections.

The final stage is assembly and testing. At this stage, the components need to be installed on the PCB according to the design requirements, and the electrical performance test is performed to ensure that the circuit connection is normal and there are no short circuits or open circuits. After passing the test, the ultra-thin BT PCB can be put into use.

In general, although the manufacturing process of ultra-thin BT PCB is similar to traditional PCB manufacturing, due to its ultra-thin characteristics, higher-precision process control and stricter material selection are required to ensure the quality and performance of the final product.

After the circuit layer is printed, chemical etching is performed to remove unnecessary metal and form clear circuit lines. This process requires precise control of etching time and solution concentration to ensure line accuracy and quality. After etching is complete, perform a thorough cleaning to remove residual chemicals and impurities.

Next comes the drilling and plating steps. Through precisely controlled drilling machines, holes are drilled where needed to form through holes for mounting components and connecting different circuit layers. This is followed by electroplating, which involves applying a layer of conductive material to the vias to ensure circuit connectivity and stability.

Finally, assembly and testing are done. In this step, the components are mounted onto the ultra-thin BT PCB and the functionality and performance of the circuit are verified through electrical performance testing. This includes checking connectivity, resistance, capacitance and other electrical characteristics to ensure product quality meets requirements.

These steps are crucial in the manufacturing process of ultra-thin BT PCB, and each step requires precise process control and strict quality inspection to ensure the quality and reliability of the final product.
