20TB hard drive launched before 2020 with glass substrate manufacturing

In the past few years, the hard disk density slowdown the growing speed. Although Seagate and the West continue to work hard, put more discs, use helium, continue to introduce a larger capacity hard drive, but the hard disk density to enhance the speed gradually slow down, it is an indisputable fact. Now West and Seagate are working hard on 20TB high-capacity hard drive which is manufactured with glass substrate.

So far, only the notebook hard drive using glass substrate. Compared with the aluminum plate glass has several advantages. First, the glass is stronger than aluminum, allowing manufacturers to put thinner and lighter discs. In addition, compared with the aluminum substrate, the glass substrate is more flat and more smooth, more closely together, when the heat expansion is much weaker, that is to say the ability to cope with thermal expansion stronger. Also, let the spindle press the glass plate at a given speed, the need for less power, if the use of aluminum discs, because of its weight heavier, so a little higher energy consumption.

Japanese company Hoya believes that HDD manufacturers will use glass in 3.5-inch hard drive. Hoya shows a prototype glass disc that has two thicknesses, one for 0.5 mm and another for 0.381 mm. Currently the disc thickness is 0.635 mm. There must be a gap between the disc and the disc. If the disc size is reduced by 40%, more discs can be loaded in the same capacity. The glass substrate facilitates the introduction of heat-assisted magnetic recording (HAMR). If you want to write data on the hard disk, the hard disk will heat the writing part with the laser. Seagate is ready to roll out HAMR drives in 2018 and expand capacity to 20TB by 2020.

Wireless charging principle Detailed

Smartphones that support wireless charging are available from around the summer of 2011. Any handset device can use the global standard "Qi" specification. Parking can be charged EV (electric car) with the charging system.

Wireless charging has been in the electric toothbrush, electric shavers, wireless phones and other parts of household appliances in the practical, and now its scope of application has expanded to the field of smart phones.

At present, most of the smartphones and chargers that support wireless charging on the market are in line with the "Qi" specification developed by the industry-based "Wireless Charging Alliance (WPC)" in the United States.

Wireless charging methods include "magnetic resonance" and "radio reception" and other means, Qi is used "electromagnetic induction". By achieving standardization, as long as it is with Qi logo products, any handset device can be charged.

1.27mm Ptch FFC cable

Advantage of 1.27mm pitch FFC cable are Small size, light weight, the design of the cable board is used to replace the larger wiring harness wire. In the current patch electronics assembly board, the insulation material FFC cable is usually to meet the miniaturization and mobility requirements Of the solution. By using the 1.27mm ffc cables, the total weight and volume of the cable is reduced by 70% compared to conventional round wire harness. The cable can also be increased by using the reinforcement material or liner method to obtain Additional mechanical stability.

When the circuit of the circuit is too complicated and the single layer board can not be routed or need copper foil for grounding shielding, you need to choose double or even multilayer fpc cable. Multilayer fpc cable have the holes connecting the layers of copper foil. This is a typical difference of single layer fpc cable .

Advantages and Disadvantages of Automotive FFC Cable

Automotive FFC cable including single-sided, double-sided and multi-layer board. The substrate based on polyimide CCL-based materials. Its advantage including high heat resistance, good dimensional stability, and good electrical insulation performance.

Automotive FFC cable shortcomings:

(1) high initial cost of a single time

Since the flexible PCB is designed and manufactured for special applications, the cost of the circuit design, wiring, and backplane is high.

(2) difficult changes and repair

Once the soft PCB is made, it must be changed from the bottom of the map or the preparation of the light painting program, so it is not easy to change its surface covered with a protective film, to be removed before repair, repair and then to restore, it is more difficult jobs.

(3) size is limited

It can not be done very long, very wide.

(4) can be damage easily when improper operation.

Improper operation of the installation can easy to cause damage to the soft circuit, the soldering and rework needs of trained personnel operation.

Advantages of automotive cable FFC cable:

(1) can be free to bend, winding, folding, according to the space layout requirements of any arrangement, and in any three-dimensional space to move and stretch, so as to achieve the integration of components and wire connections.

(2) the use of FPC can greatly reduce the size and weight of electronic products.

(3) FFC also has good heat dissipation and weldability as well as easy to install, the overall cost is low, the combination of soft and hard design to a certain extent make up for the flexible substrate in the component carrying capacity of a slight shortage.

The Function and Solution of Robot FFC Cable

The Function and Solution of Robot FFC Cable


Robot FFC cable is a simple structure flexible board. Usually the materials are substrate, transparent plastic, copper foil, protective film and transparent plastic. The foil is subjected to a process such as etching to obtain the desired circuit, and the protective film is to be drilled to expose the corresponding pads. After cleaning, combined by rolling and then plated at the exposed pad portion Gold or tin. General also stamping into the corresponding shape of the small circuit board. Now, many products used the cable, because the cable can be twists and turns, in the printer, mobile phones, notebooks and many other products.

The type of robot FFC cable:
1, single panel
The use of single-sided PI copper plate material in the line after the completion of a layer of protective film, forming a single-layer conductor only a flexible circuit board.
2, ordinary double panel
The use of double-sided PI board deposited copper material in the double-sided circuit is completed, the two sides were added with a protective film, as a double conductor with a circuit board.
3, the substrate to generate a single panel
The use of pure copper foil material in the circuit process, respectively, in the two sides of each layer plus a layer of protective film, as a single-layer conductor, but in the circuit board has a conductor on both sides of the exposed circuit board.
4, the substrate to generate double-sided
A double-sided conductor circuit board having a two-layer, one-sided PI-plated copper material material is bonded to each other at a specific position to form a double-sided conductor circuit board in a localized region, A circuit board with high flexural properties.

Flexible printed circuit board (FPC) design specifications

With the miniaturization trend of all the electronic, flexible board is more and more popular because of its inherent light, thin, flexible and other advantages. Relative to the ordinary hard board, the flexible board design is more difficult. It is more difficult to the designer integrate all the electronic functions in such a small and thin flex pcb. In addition to considering the electrical interconnect, the design have to concern about the flexibility, reliability and other structural requirements. The flexible board selection, processing methods and precision will affect the final product price and lead time. All these requires the designer to be very concerned about the cost analysis. It is necessary to consider the electrical performance and the structure.
