The Manufacturer Process of Ultrathin IC Substrate.

The manufacturing process of ultra-thin IC substrates is a highly precise and multi-step process, and each step requires strict control and high-precision operation to ensure the quality and performance of the final product. The following are the main steps in ultra-thin IC substrate manufacturing:

The first step in manufacturing ultra-thin IC substrates is to prepare the substrate materials. Commonly used substrate materials include polyimide (Polyimide) or liquid crystal polymer (LCP), which have excellent electrical insulation properties and mechanical strength. Substrate materials are typically supplied in film form, which is cut and cleaned to ensure a dust-free surface.

After the substrate material is prepared, a layer of copper needs to be deposited on its surface. This is usually achieved by chemical vapor deposition (CVD) or physical vapor deposition (PVD). This process requires precise control of the thickness of the copper layer to ensure it provides good electrical conductivity while maintaining the overall ultra-thin nature.

The next step is photoresist coating and exposure. A layer of photoresist is coated on the substrate, and then the designed circuit pattern is projected onto the photoresist through a mask. After exposure, the photoresist undergoes chemical changes in the areas hit by the light.

After the exposure and development process, only the copper pattern that needs to be retained will be left on the substrate. Next, the copper layer not covered by the photoresist is removed through an etching process. Commonly used etching methods include wet etching and dry etching. Which method to choose depends on the specific design requirements and process conditions.

After etching is complete, holes need to be drilled in the substrate for subsequent electrical connections. These holes can be through holes for through-hole mounting technology (THT) or blind or buried vias for surface mount technology (SMT). Drilling usually uses high-precision laser drilling equipment or mechanical drilling equipment.

After drilling, the electronic components begin to be placed on the substrate. For the SMT process, components are placed directly on pads on the surface of the substrate. For the THT process, the pins of the component are inserted into the substrate through drilled holes and then soldered to the other side of the substrate.

After the electronic components are placed, the next step is soldering. Soldering can be done by reflow or wave soldering, depending on the mounting technique used. Reflow soldering is commonly used for SMT components, while wave soldering is commonly used for THT components.

The final step is testing. Through electrical testing and functional testing, we ensure that each ultra-thin IC substrate meets design specifications and performance requirements. Testing steps include open and short circuit detection, functional testing and reliability testing to ensure the high quality and reliability of the product.

The manufacturing process of ultra-thin IC substrates is a highly complex and precise process that requires multi-step precise operations and strict control. Every step, from substrate preparation to final testing, is critical to product quality and performance.
