WellCircuits has rich experience in the research and development and production of HDI products. HDI circuit boards have achieved large-scale mass production for interconnection products from 1st order to any order, and they are mainly applied to products such as mobile phones, tablets, and wearable devices.

The mobile Internet application field is accelerating the iteration of intelligent mobile terminal products, such as smart phones, tablets, smart watches, and wearable devices. The products are gradually developing towards lighter, thinner, and more intelligent application directions, which have put forward higher requirements for display technology and data transmission and processing capabilities. The diversification of uses and the light – weight and thin – volume of products also prompt the printed circuit boards to arrange more wires within a limited area and continuously develop in the ultra – fine – grained directions such as narrower line width, denser wiring, and more precise processes.
