HDI PCB

High-dense-interconnect PCB boards have a higher wiring density per unit area than typical PCBs. With changing technology, printed circuit board technology has evolved to meet the demand for smaller and faster products. HDIs have denser wiring, resulting in lighter, more compact PCBs. Instead of using several PCBs in a device, one HDI board can replace all the preceding boards.

Why choose HDI printed circuit boards?

The ability to “do more with less” is the primary advantage of HDI printed circuit boards with technology constantly seeking greater precision. HDI PCBs enable the deployment of many transistors for improved electronics performance while lowering power consumption. Because of the shorter distance connections and lower power requirements, signal integrity is also enhanced.

Modern designs often require highly advanced BGA with very fine pitch, witch is impossible to fanout without HDI technology.

Microvias are also more dependable than through holes because they have a smaller aspect ratio; they are more reliable than typical through holes, allowing HDIs to achieve remarkable performance with superior materials and parts.

Where are HDI PCBs used?

HDI PCB board is usually found in complex electronic devices that demand excellent performance while conserving space. Applications include mobile /cellular phones, touch-screen devices, laptops, digital cameras, 4/5G network communications, and military applications such as avionics and smart munitions.

Automotive and aerospace industries, where lower weight can mean more efficient operation, have been utilizing HDI PCBs at an increasing rate. For example, today’s cars have around 50 microprocessors on board that play a role in engine controls, diagnostics, safety features, and other conveniences.

The high-density technology promotes improved performance and smaller, more cost-effective medical devices, potentially improving the accuracy of monitoring and medical testing.

HDI printed circuit boards play a significant role in industrial automation and IoT, as it is becoming more common in manufacturing, warehousing, and other industrial settings. Businesses use electronic tools to keep track of inventory and monitor equipment performance, collect usage data, and connect to the internet to communicate with other smart devices, as well as to relay information to management and help optimize operations.

Yes. Since we have all kinds of factories, we can offer a wide range of delivery times. Also, many of our volume factories have prototype services in-house, so both prototype and volume will be produced in the factory.

Yes, there are still a lot of PCB manufacturers inside Europe, and we have carefully selected PCB manufacturers as our suppliers for express prototyping, but also a producer of solder paste stencils for PCB soldering. This laser-cut solder paste stencil can be of various types, such as vector guard, zellflex, genesis, and more, but also multi-level stencil.

All deliveries will pass Multi-Teknik quality control, and we check quality with the CAM-prepared data made at the beginning of the process. You will also have a CoC and quality control document along with the delivered PCB.

The straight answer is no. You will have the correct quantity of PCBs and only pay for the correct ones. The x-outs are not considered when counting and will not be included in the amount on the delivery note.

Flex PCB is the same as the ordinary PCB, but with the difference that the base material is flexible. This is to let the circuit be able to be bent during a lifetime or be installed in a static folded mode. There are many design rules to take into account when designing flex PCB.

A PCB (printed circuit board) is a board with a printed copper pattern that forms a given circuit to enable the designer to connect several electronic components rationally. The most common material today for PCB boards is a combination of woven glass fiber and epoxy. For more demanding electronic designs, there are a lot of other base materials, such as ceramics, Teflon, polyimide, aluminum (mcpcb), and more.

The stack-up is the schematic view of how all copper layers, cores, and prepregs are grouped with data regarding thickness and material selections. Often impedance controlled PCB has this data in the stack-up view as well.

There is no exact date for the invention of the PCB; the truth is that it is a line of innovations that together contributed to today’s PCB. Of course, there is endless material about this on the Internet, but we have tried to pinpoint an unambiguous answer.

Mainly in China, where the world’s production is concentrated today, but also in Taiwan and inside Europe.

No one knows why just green became the standard color of PCB solder masks. But the rumor says that the electronic production staff in the USA during the second world war had voted about what colors were most friendly to eyes during a long time of work. And the green has become favorite.
