From 1+N+1 to X+N+X stack-ups, “all layer” technology and in a wide range of technological variants.

An HDI PCB is a PCB which has a far higher wiring density than a conventional through hole PCB.  Per IPC-6012 (1.4.1) this is defined as a design which has an average number of electrical connections/cm² of 20 or more, on both sides of the PCB.

An HDI PCB uses finer features than a conventional PCB, enabling tighter packaging densities and lower layer count and/or reduced size. All HDI PCBs should follow IPC2226 – Sectional Design Standard for High Density Interconnect (HDI) Printed Boards. IPC2226 separates HDI into types I to type VI depending on usage and complexity.

Typical applications are smartphones, where space is at a premium, and aerospace where smaller size and/or reduced weight are key drivers.

Yaheng Circuits produces prototype, mid and high volume single sided PCBs, with a copper thickness ranging from 1 to 20 ounces. Operating temperatures range from 130 C to 230 C, depending on base material type. Single sided boards are available with many surface finishes including Organic Surface Protectant (OSP), Immersion Silver, Immersion Tin, Electroless Nickel Immersion Gold (ENIG) and either leaded or lead-free Hot Air Solder Level (HASL).
