HDI PCB(High Density Interconnector PCB), that is high-density interconnect PCB, is a line distribution density using micro-blind and buried via technology. It includes inner layer lines and outer layer lines, and then uses drilling and hole metallization to realize the internal connection function of each layer line.

So far, almost all FPC manufacturing processes are performed by subtraction (etching method). According to Cabor technology, copper foil is usually the starting material for forming a corrosion-resistant layer by photolithography, and the surface of the copper foil is removed from the copper surface to form a circuit conductor. Due to problems such as side corrosion during the corrosion process, the etching method has limitations in microcircuit processing.

The most basic purpose of PCB surface treatment is to ensure good solderability or electrical properties. Because the copper in the air is easy to oxidize, the copper oxide layer has a great influence on welding, and it is easy to form false welding, which will seriously cause the pads and components to be unable to be welded.

The multilayer board process is developed on the basis of the double-sided metallization process. According to experts from the China Epoxy Resin Industry Association, this process has several unique contents in addition to the double-sided process: inner-layer interconnection of metallized holes, drilling and decontamination, positioning systems, layering, and special materials. Our commonly used computer cards are basically double-sided printed circuit boards based on epoxy glass cloth, one of which is plug-in components, and the other side is the soldering surface of the component feet. We can see that the solder joints are very regular. We call the discrete welding surface a solder joint.

PCB production process flow is different and changing with the progress and difference of PCB type (type) and process technology. At the same time, it is different as PCB manufacturers adopt different process technologies. Different production processes and technology can be used to produce the same or similar PCB products.

At first, let us understand how to create the next circuit board manufacturing process. Learn how to set or execute a goal or function. Then, in PCB design, this term refers not only to the category of process data, but also to the manufacturer's capabilities. These data are based on the performance of the manufacturer's equipment and the entire design process.
