HDI is widely used in mobile phones, digital (camera) cameras, MP3, MP4, notebook computers, automotive electronics and other digital products, among which mobile phones are the most widely used. HDI boards are generally manufactured by the build-up method.
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.
Multilayer boards were invented in 1961. Its production method is generally to make the inner layer graphics first, and then use the printing and etching method to make a single-sided or double-sided substrate, and incorporate it into the designated interlayer, and then heat, press and bond it. As for the subsequent drilling, It is the same as the plated through-hole method of the double-sided board.
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.
With the rapid development of electronic design and communication fields and the application of cloud computing, products have higher and higher requirements for data volume, and data transmission rates are getting faster and faster. At the same time, the performance of high-speed plates that carry data transmission is also required to be higher and higher.So what should be paid attention to when using high-speed plates?
Double-sided PCB is a very important PCB board in the circuit board, usually made of epoxy glass cloth copper clad board.
