Rigid-flex board is a combination of flexible board and hard board. It is a circuit board formed by combining a thin layered flexible bottom layer with a rigid bottom layer, and then laminating it into a single component.The flexible board is used to replace the cable assembly to complete the highly reliable connection and transmission of power and electrical signals.The product can work stably and reliably for a long time under harsh environments such as high and low temperature, high humidity, vibration, salt spray, and low air pressure. At present, Jonhon Optronic has provided rigid and flexible printed board solutions for aviation, aerospace, ships, weapons and other fields.

Flow chart of single-sided FPC circuit board: engineering documents - copper foil - Pretreatment - press dry film - exposure - Development - etching - film stripping - AOI - Pretreatment - coating film (or ink printing) - pretreatment before electroplating - electroplating - post electroplating - reinforcement - appearance punching - electrical measurement - appearance inspection - shipment;

From "Why are chips stuck" to "How can the shortage of chips be alleviated", we can clearly feel that everyone has a much deeper understanding of the importance of chips. However, when many students contact the chip industry and want to know more, they will still have a variety of questions to answer!

An Integrated Circuit (IC), also commonly known as a microchip or chip, is a miniaturized electronic circuit that consists of multiple interconnected semiconductor devices, such as transistors, diodes, resistors, and capacitors, fabricated on a single semiconductor substrate, usually made of silicon. The components on an integrated circuit are designed to perform specific electronic functions, and the entire circuit is manufactured as a single unit.

Semiconductors have a wide range of applications, almost permeating every aspect of our lives. It is widely used in fields such as electronic products, communication equipment, computers, medical equipment, etc. According to different application fields, semiconductors can be divided into six major sub sectors:

HDI in HDI Board is the abbreviation of High Density Interconnector. It is a kind of (technology) for producing printed circuit boards. It uses micro-blind and buried via technology for a circuit board with a relatively high line distribution density. HDI is a compact product designed for small-capacity users.
