What is the manufacturing process of BT epoxy resin PCB?

The manufacturing process of BT epoxy resin PCB is a complex and precise process, which involves multiple key steps, each of which has an important impact on the quality and performance of the final product.

First of all, the first step in manufacturing BT epoxy resin PCB is material preparation. At this stage, the raw substrate materials are selected and cut to appropriate dimensions to ensure they are suitable for subsequent processing steps. Typically, fiberglass cloth and epoxy resin are used as the basic materials of PCB.

Next comes the coating step. At this stage, the fiberglass cloth is coated with a thin layer of epoxy to ensure better curing and bonding in subsequent steps. The uniformity and quality of the coating are critical to the performance of the final PCB.

This is followed by exposure and etching. During the exposure process, the desired graphic pattern is formed by shining a light source on the coated substrate. Then, during etching, a circuit pattern is formed by applying a chemical solution to the exposed pattern, dissolving away the unexposed areas.

After completing the circuit pattern, the next critical step is to drill holes. At this stage, holes are drilled into the PCB using high-precision drilling machines to facilitate subsequent component mounting and connection.

Next comes electroplating. During the electroplating process, the conductive properties of the circuit pattern are enhanced by coating a layer of metal (usually copper) on the surface of the PCB. This step can also improve the corrosion resistance of the PCB and increase its lifespan.

Finally comes cleaning and inspection. During the cleaning process, the PCB is cleaned to remove any remaining dirt or chemicals. During the inspection phase, high-precision testing equipment is used to ensure that the quality of the PCB meets specifications.

In general, the manufacturing process of BT epoxy resin PCB is a highly precise and complex process, and each step requires strict control and monitoring to ensure that the quality and performance of the final product meet the expected standards.

What are the specific steps for manufacturing BT epoxy resin PCB?

The manufacturing of BT epoxy resin PCB involves a series of key steps, from material preparation to assembly testing, each link is crucial. These steps and their key points are detailed below.

First of all, the first step in manufacturing BT epoxy resin PCB is material preparation. At this stage, raw materials such as fiberglass cloth, epoxy resin, and copper foil need to be prepared. Fiberglass cloth is typically used as the base material for PCBs, while epoxy resin is used to cover circuit layers and provide insulating protection. Copper foil is used to form the conductive layer. The key point is to ensure that the material quality meets the requirements to ensure the performance and reliability of the final PCB.

Next is the printed circuit layer. In this step, the designed circuit pattern needs to be printed on the fiberglass cloth using photolithography technology and coated with a thin layer of copper foil. This process requires precise operation and control to ensure the accuracy and clarity of circuit patterns.

Then comes chemical etching and cleaning. At this stage, a chemical solution is used to etch away the unwanted copper foil, leaving the desired conductive pattern. Afterwards, the PCB must be thoroughly cleaned to remove residues produced during the etching process and to ensure that the surface is clean and free of contamination.

Next comes drilling and plating. In this step, a high-precision drilling machine is used to drill holes on the PCB where conductive connections are needed to facilitate installation of components and wiring. The holes are then coated with a layer of metal, usually copper, to enhance conductivity and corrosion resistance. This process requires highly precise operations to ensure accuracy of hole diameter and position.

Finally comes assembly and testing. At this stage, the electronic components are soldered to the PCB and necessary tests and inspections are performed. This includes power-on testing, connectivity testing, electrical performance testing, etc. The key point is to ensure that the soldering quality is good, the circuit connections are reliable, and the performance of the entire PCB meets the design requirements.

To sum up, the specific steps for manufacturing BT epoxy resin PCB include material preparation, printed circuit layering, chemical etching and cleaning, drilling and plating, as well as assembly and testing. Each step has its key points and technical difficulties, which require precise control and operation by experienced technicians to ensure the stability of final product quality and performance.
