In 2022, the market is flagging, the PC market and the demand for electronic consumption are declining, the major manufacturers are cutting orders continuously, the inventory is high successively, and the overall market supply and demand mismatch; There are also cases of short supply, such as logic chips, IGBT, automotive MCU and so on to maintain a high business status.   In the face of this market situation, look at Taiwan Semiconductor, Intel, Samsung, SK Hynix,  United electric, and other major manufacturers, how to optimize the industrial layout adjustment, to meet the 2023 new start.     [Taiwan Semiconductor Manufacturing Company]   Attack overseas market, improve 3 nm yield; Technology development 2-nanometer process; The expenditure budget has been further revised down.   From the perspective of the process node, the utilization rate of 7nm and 6nm capacity of TSMC has declined, which is estimated to take several quarters to adjust. It is expected that the demand is expected t

  CPU   Generally speaking, the CPU computing power is the weakest, although the CPU has the highest main frequency, but the single is also 8 cores, 16 cores, a core of 3.5g, 16 cores is 56g, and then consider the instruction cycle, up to 30g times per second multiplication. Still fixed point.   D SP   Although the main frequency of the DSP is not as good as the CPU, but the multiplier is more, casually with 16 multipliers, or floating point. And then a 4 cores, 8 cores, and specific algorithms hardware acceleration, so although the main frequency is only 1,2g but the computing power is still stronger than the CPU. Of course, now there is a CPU with a dedicated multiplier, DSP also set the ARM core, the boundary between the two began to blur.   All DSP calculations use floating point algorithms, and there are no bit or integer instructions yet.   GPU   GPU is designed for image processing, the main frequency is generally around 500mhz, but there are many cores, such as titan, there are

1.  PCB board surface treatment   PCB board surface treatment processes include: anti-oxidation, spray tin, lead-free spray tin, sink gold, sink tin, sink silver, hard gold plating, full-board gold plating, gold finger, nickel-palladium-gold OSP, etc.. Requirements are mainly: lower cost, good solderability, harsh storage conditions, short time, environmentally friendly processes, good welding, flat . Tin spraying: Tin spraying boards are generally multi-layer (4-46 layers) high precision PCB prototype boards, which have been used by many large domestic communication, computer, medical equipment and aerospace companies and research units.   The connecting finger is the component on the memory stick that connects to the memory slot, and all signals are transmitted through the gold finger. Gold fingers are composed of numerous gold-colored conductive contacts, which are called "gold fingers" because of their gold-plated surface and the finger-like arrangement of the conductive
