The HPI of current solid storage hard disk is required for greatly compatible SATAIII agreement, and its traffic rate is that 6Gb/s, military project and aerospace standard typically require that storing device can cross the random vibration of 10-2000Hz.Therefore must ensure to be capable of in speed SATAIII signal attenuation when designing connector the least and the random vibration of 10-2000Hz can be resisted simultaneously.
Along with the raising of integrated level, storage device have to consider store the weight of device itself, size and how to carry out the problems such as heat conduction in the design of structure, and electronic equipment dissipating heat mode mainly includes following several:
(1) natural cooling (independent role of heat conduction, free convection and radiation heat transfer or the combination of two or more heat exchange form)
(2) air is forced to cool down
(3) liquid is forced to cool down
(4) steam cooling

Described device reinforced liner, module reinforced liner are provided with the heat dissipation channel 4 of thermal resistance of a plurality of end, and each is designed with air-guiding hole.
Described device reinforced liner, module reinforced liner can use the aluminium section bar of good heat conductivity.
Described aviation connector is that speed can cross 6Gb/s, and vibrational energy crosses the air plug part of 10-2000Hz random vibration test.It is able to ensure that reinforcement type solid-state storage device is carrying out in data exchange process with main frame, it is possible to realize high-speed read-write, and do not have to fall the problem such as dish and read-write error.The aviation connector 144662 and 144680 of ERNI company, the single-ended impedance of this connector is 50ohm, difference disclosure satisfy that the resistance requirements of 100ohm, and contact pin can cross the signal of 6Gb/s speed, essential point is that this connector can cross the random vibration test of 10-2000KHz simultaneously.

Signal Integrity Design: in Signal Integrity Design, the problem of our critical concern is how to eliminate the reflection of signal, crosstalk, EMI and direct-current coupling.Signaling reflex often by the resistance value of holding wire not to and impedance discontinuity caused, in SATA protocol, require that differential impedance is continuous print 100ohm impedance, such guarantee signal occurs without reflection superposition phenomenon in transmitting procedure.We need the dense degree of the thickness of slab according to PCB and storage board to arrange the stack layer of PCB, then calculate live width and the line-spacing of each layer differential lines further according to stack thickness, meet the resistance requirements of 100ohm.Cross-interference issue is also that we need concern, defers to the space requirement between 3W criterion i.e. differential pair and is more than or equal to three times of live widths, so could reduce the error in data problem occurring that crosstalk brings between differential lines.On SATA line, we typically use 0.01uF electric capacity to carry out direct-current coupling, prevent direct current signal from flowing into solid-state hard disk controller and burn chip.EMI problem is mainly caused by the antenna effect of transmission line, can not occur being not attached to the line of chip pin in PCB design, and it is the least to ensure returned signal area that every signals layer is offered to complete power plane, so could effectively reduce EMI.By the layout to signal location, it is to avoid high speed signal is by interfering during pin arranged in parallel connector so that it is SATA III that frequency can be supported to be 6G.

Fig. 1 is the conceptual design block diagram of reinforcement type solid-state storage device, as it can be seen, include aviation connector, DDR, SATA controller, power supply and flash storage medium.SATA controller carries out data interaction by aviation connector and main frame, and DDR is as caching the data that temporary transient storage host sends, and data are ultimately stored in flash storage medium.
SATA protocol standard is followed in communication between reinforcement type solid-state storage device and computer, SATA protocol is divided into four layers from top to bottom: physical layer, link layer, transport layer and application layer, physical layer is responsible for transmission and the reception of Low Voltage Differential Signal, and realize SATA interface initialization and auto-speed negotiation functionality, link layer is responsible for transmission and the reception of frame, transport layer completes encapsulation and the parsing of frame, and application layer is responsible for execution and the parsing of all orders.

Fig. 3 is the structural representation of reinforcement type solid-state storage device, because during vibration-testing, the frequency of vibration of vibration table and pcb board has somewhat difference, PCB arises that in vibration processes deformation causes the surface mounting component of some BGA package on pcb board or QFN encapsulation the situations such as sealing-off occur, so the weight of solid state hard disc itself and size determine uses the position of fixed screw holes on the great screw of diameter and plate.Simultaneously in vibration processes, due to the frequency of vibration difference between vibration table and PCB, there will be the part that screw contacts with pcb board on a vibration table polishing situation occurs with screw by fixing for pcb board if simple, the internal planes that there will be PCB if polishing phenomenon is serious is electrically connected to together by screw, ultimately result in solid state hard disc to break down, therefore our solution is to use aluminium alloy structure that pcb board is screwed into an entirety with structure, again by this integral installation to main frame, so in vibration processes, main stress is undertaken by structure, substantially reduce the stress suffered by PCB, guarantee that solid state hard disc does not haves fault.
Fig. 4 is the radiating treatment schematic diagram of reinforcement type solid-state storage device, the main pyrotoxin of solid state hard disc is solid-state hard disk controller, if the heat of hard disk controller sheds the most in time, then may affect the DDR of periphery, Flash normally works, therefore the structure of the design is support rack type structure, the not structure space closed.Surrounding in structure all leaves radiating groove simultaneously, it is possible to effectively allow the heat of solid-state hard disk controller distribute in time, it is ensured that the stability of hard disk operational.
