1. From the perspective of segmented products: HDI and FPCB demand is less than expected, but high-level digital boards and high-end packaging substrates are in strong demand;
2. From the perspective of product application: the demand for mobile phones and automotive electronics is gradually rising, and the demand for communication base stations, servers, and computers is relatively strong;
3. From the perspective of production area: the value of traditional PCB manufacturing such as Japan and South Korea has been declining in recent years, but mainland China has continued to grow (in 2020, affected by the new coronary pneumonia, the global scale will decrease, but there will be a rebound upward trend afterwards).
1. The level of PCB technology is often evaluated in terms of minimum line width/spacing, minimum aperture/annular ring, maximum/minimum dielectric thickness, thickest/thin copper, pitch connection pad spacing), impedance control, dimensional tolerances, etc.
2. PCB market prices are often priced per unit area, and are related to factors such as product structure size, technical difficulty, delivery volume, and delivery time.
3. PCB is a customized product, the production process is long, and there are many types of raw materials used, and clean production and environmental protection must be considered.
Digital inkjet printing technology is a non-contact dot matrix printing technology, which forms an image by directly ejecting ink droplets from a small hole to a specific position on the substrate, using the principle of additive method.
Ink-jet printing is a fast, simple, flexible, and clean PCB production method that has been applied to the field of all-printed electronics, bringing a new technological revolution to PCB manufacturing. This technology has been gradually marketed. At present, inkjet printers and character inkjet printers have appeared in the market. The deeper penetration of digital printing technology in the PCB manufacturing industry and even the application of digital inkjet printing technology in all links will be just around the corner.
Compared with traditional technologies such as screen printing, inkjet printing technology has the following advantages:
1. High printing accuracy. Inkjet printers can basically print circuits with a line width of 20-50μm. Compared with screen printing technology, the resolution has been improved several times.
2. Fully digital. Inkjet printing is a fully digital printing, which completely breaks away from the cumbersome procedures of traditional printing technology, and can minimize the time to market for products. For those products that require high time, this printing method will be the best select.
3. Environmental protection and pollution-free. The process principle of the full additive method makes no waste of excess materials, and also eliminates the steps of washing and etching that can cause environmental pollution and wastewater. This complete digital technology has the advantages of flexible operation, high resolution and low cost, and is compatible with almost all types of substrates. It can directly convert electronic designs into printing files, greatly reducing the process in PCB manufacturing and saving materials.
