How to manufacturing BT Resin PCB?

A Step-by-Step Guide to Manufacturing BT Resin PCBs:

Manufacturing BT Resin Printed Circuit Boards (PCBs) involves a series of precise processes to ensure the final product meets the stringent requirements of modern electronic applications. Here’s a comprehensive guide outlining the steps involved in manufacturing BT Resin PCBs:

  1. Material Selection: The manufacturing process begins with the selection of high-quality BT Resin material, which typically comes in the form of prepreg sheets. These sheets are impregnated with uncured BT Resin and are reinforced with glass fibers to provide mechanical strength.
  2. Layer Stacking: Multiple layers of prepreg sheets are stacked together, alternating with copper foil layers. The arrangement depends on the desired number of copper layers in the final PCB design. The stack is then subjected to heat and pressure to bond the layers together.
  3. Drilling: Holes are drilled through the layered stack using precision drilling machines. These holes, also known as vias, will later facilitate the electrical connections between different layers of the PCB.
  4. Copper Plating: After drilling, the interior walls of the vias are plated with a thin layer of copper using an electroplating process. This copper plating enhances conductivity and ensures proper electrical connections between layers.
  5. Circuit Patterning: A layer of photoresist is applied to the surface of the PCB stack. A photomask, containing the desired circuit pattern, is then aligned and exposed to UV light. The exposed areas of the photoresist harden, while the unexposed areas remain soluble. Subsequent development and etching processes remove the unexposed photoresist and unwanted copper, leaving behind the desired circuit pattern.
  6. BT Resin Lamination: The circuit-patterned PCB stack undergoes lamination in a heated press. Heat and pressure are applied to cure the BT Resin, bonding the layers together permanently. This lamination process also helps to remove any remaining solvent and air bubbles from the PCB stack, ensuring uniformity and reliability.
  7. Surface Finishing: The final step involves surface finishing to protect the exposed copper traces and provide solderability. Common surface finish options for BT Resin PCBs include hot air solder leveling (HASL), electroless nickel immersion gold (ENIG), and immersion silver.
  8. Quality Control and Testing: Throughout the manufacturing process, rigorous quality control measures are implemented to ensure the PCBs meet industry standards and customer specifications. Testing may include checks for dimensional accuracy, electrical continuity, insulation resistance, and solderability.

By following these precise steps, manufacturers can produce high-quality BT Resin PCBs that offer exceptional thermal stability, mechanical strength, and electrical performance, meeting the demanding requirements of various electronic applications.

Higher layer counts require more intricate fabrication processes and increased material usage, leading to higher costs. Furthermore, complex PCB designs with densely packed components, fine traces, and small vias may require advanced manufacturing techniques, driving up the cost further.
  3. Board Size and Thickness: The size and thickness of the PCB also influence its cost. Larger boards require more material and may necessitate specialized handling and processing equipment, resulting in higher manufacturing costs. Similarly, thicker PCBs may require additional material and longer processing times, adding to the overall cost.
  4. Surface Finish and Special Features: The choice of surface finish and any additional features or special requirements specified by the customer can impact the cost of BT Resin PCBs. Surface finishes such as gold plating or immersion silver incur additional expenses compared to standard finishes like HASL. Moreover, features such as impedance control, blind vias, and buried vias may require specialized fabrication processes, contributing to higher costs.
  5. Manufacturing Volume: Economies of scale play a significant role in determining the cost of BT Resin PCBs. Larger production volumes typically result in lower per-unit manufacturing costs due to optimized production processes, bulk material procurement, and reduced setup times. Conversely, smaller production runs may incur higher costs per unit.
  6. Lead Time and Turnaround Time: Shorter lead times and faster turnaround times often come at a premium. Manufacturers may charge expedite fees for rush orders or prioritize production schedules for customers willing to pay for faster delivery, influencing the overall cost of BT Resin PCBs.
  7. Quality and Certification Requirements: Meeting specific quality standards and obtaining certifications, such as ISO 9001 or IPC Class 3, can impact the cost of BT Resin PCBs. Manufacturers may invest in quality control measures, testing equipment, and compliance processes to ensure that PCBs meet the required standards, resulting in higher manufacturing costs.

In conclusion, the cost of BT Resin PCBs is influenced by a multitude of factors, including material costs, layer count, board size, surface finish, manufacturing volume, lead time, and quality requirements.

What is the manufacturing process of BT resin PCB?

The manufacturing of BT resin PCB is a complex and delicate process, which usually includes the following key steps:

Material preparation: The first step in manufacturing BT resin PCB is to prepare the required materials, which mainly include BT resin substrate, metal foil (such as copper foil), etc. These materials need to undergo strict inspection and selection to ensure that their quality meets requirements.

Image processing: Next, by converting the designed circuit diagram into an image, the circuit layer is printed on the surface of the substrate. This step is usually accomplished by photolithography, which requires the use of photoresist and photolithography equipment to transfer the circuit pattern to the substrate.

Chemical etching: After the image processing is completed, chemical etching technology is used to remove unnecessary parts of the metal foil to expose the required circuit pattern. This step requires the use of chemical etchant, which is achieved by immersing the substrate in the etching solution and controlling the etching time and temperature.

Drilling and Plating: Next comes the drilling and plating steps. In this step, vias are drilled and metallized to enhance conductivity. Drilling is usually done using a CNC drill press, while plating deposits a layer of metal, such as copper, on the hole walls by soaking the substrate in a metal salt solution to create a conductive layer.

Final processing: The last step is final processing, which includes cutting, cleaning and inspection. During the cutting process, large substrates are cut into smaller pieces of the desired size. Cleaning is to remove contaminants and residues generated during the production process to ensure that the PCB surface is clean. Finally, through inspection, ensure that the PCB quality meets the requirements and does not have any defects.

Each step is crucial and requires precise operations and strict quality control to ensure that the quality of the final manufactured BT resin PCB is stable and reliable. Due to the particularity of BT resin PCB, special attention needs to be paid to its thermal stability and mechanical strength during the manufacturing process to meet the needs of different application scenarios.
