Originally established in 1998, Stariver Circuit is a leading PCB manufacturing (PCB),PCB assembly (PCBA) and electronics manufacturing (EMS) company based in Shenzhen that has had an amazing development from its roots to its present state today. Stariver primarily began as a trading company with only four people but quickly built up in its development to then build their first plant located in Shenzhen in 2005. Currently, Stariver has multiple branch plants and corporate offices in Fujian, Huangshi, Shanghai, Beijing, and Hong Kong. Furthermore, with over 1200 employees and more than 700 million in sales last year, it continues Stariver's growth towards the future where further cooperation with its customers, partners, and staff will occur more frequently. This will establish a solid path in order to tackle the incoming obstacles along the way.

In terms of Stariver's services, Stariver focuses on professional, high-quality work while serving customers well and this has been done by gaining full compliance and certifications for CE, RoHS, ISO9001, etc. You can have a look at more of their quality certificates and equipment used, by clicking here. They also have full capability to produce 2-12 layers of small to large quantity PCB orders while serving you, as the customer, with the best service possible.

​​In addition to Stariver's PCB production services, Stariver offers an amazing electronics component sourcing service in order to assemble your PCB according to your personal preference. They have various personnel with decades of experience to source your components and Stariver offers an incredibly wide variety of both active and passive components at your disposal with brands including Samsung, NXP, Microchip, Texas Instruments, etc. All items purchased by Stariver are guaranteed to be originally sourced from licensed distributors, ensuring quality and safety with your product. Whether your PCB requires through-hole or surface mount component assembling, Stariver has 4 SMT lines which can produce 1,090,000 points a day from small to medium batches in a short time only. Additionally, to guarantee the top quality which Stariver brings, their services, process control, and quality control systems are regularly audited and maintained, especially when dealing with its PCBA service.

​​For Stariver's PCB manufacturing service, you can either select the Standard or Advanced package where their capabilities differ from each other slightly but it all depends on your project and capacity which you require to manufacture. These are Stariver's production capabilities with the Standard and Advanced package difference shown:

​High-Density Interconnect (aka HDI) technology is gaining market approval lately as many electronics designers are trooping to get it. It is of note that HDI sales double that of its conventional lines based on the latest market trends. Ordinarily, any electronics designer must select the correct HDI PCB materials regardless of which application they are building. But with HDI, choosing the right equipment is particularly important because you are working with light, small, and powerful PCBs. The pitch is often below eight mils (equiv. 200um) while its aperture is usually below ten mils (equiv. 250um).

This section mainly describes PCB materials with low loss factor (Df) or dielectric loss tangent to reduce energy loss at high frequencies. For this reason, at least four types of HDI materials are suitable. Check them in the following sections.

• 4.1: Moderate speed and loss

These are currently the most popular PCB materials. They belong to the FR-4 family. Their ratio of dielectric constant to frequency response is not flat and therefore suffers from higher dielectric losses. Consequently, it can be found useful only for analog or digital applications that do not require high GHz.

• 4.2 High speed, low loss

This category of HDI materials has a Dk. to frequency curve flatter. The result is a significant low dielectric loss, which is up to half of what is obtainable with Medium Speed materials. Applications with approximately 0 GHz requirements will find it most useful.

• 4.3 High speed, low loss, high signal integrity

Dk's curve. The frequency is equally flat, and the dielectric loss is also quite small. Another advantage is that they eliminate unnecessary electrical noise common in other material categories.

• 4.4 High speed, shallow loss, high signal integrity, RF and microwave

Of all the HDI materials discussed, this type of Dk.to frequency curve is the flattest. Also, they have the lowest dielectric loss. This material category is most suitable for applications with GHz requirements up to 20.

​In principle, materials with lower Dk and Df. Values with excellent SI capabilities are the best choice for excellent HDI performance. Besides, the higher the quality of the required materials, the more money you are prepared to spend. Generally, high speed, a slight loss, high signal integrity, RF, and microwave materials are the most expensive categories.

​Although HDI can indeed be improved, its advantages and applications are endless. HDI PCBs are now being adopted in almost all sectors, including the military, which has further increased their acceptability.

HDI technology is rapidly developing globally, and many applications are running on it. However, choosing the right dielectric material for it can be a daunting task. There are a few factors you need to consider before making your choice, and this is what we are trying to help you in this article. We do hope you find this information useful.
