Why does the energy-saving subsidy policy that began on June 1 have no clear effect on the home appliance industry? Zhou Yinchen, an analyst at Shenyin Wanguo International, believes that after the introduction of the energy-saving subsidy policy, home appliance sales channels tend to digest low-efficiency products first, and this is affected. No significant increase in shipments of household appliances. According to the observation of Guoxin Securities in Shenzhen supermarkets and home appliance chain stores, in June the supermarkets still pushed the three-level energy-efficient air conditioners and some refrigerators, washing machines and other products that did not meet energy efficiency subsidies.
Zhou Haichen stated that from the standpoint of single product, the subsidy for energy saving is not as good as subsidies for home appliances to the countryside, but the subsidy for home appliances to the countryside for more than 4 years is 62.62 billion yuan. This time it is a one-year subsidy of 26.5 billion yuan. It is expected that the effect of policy implementation on the demand for terminals will gradually be seen in July.
According to Orient Securities analyst Guo Yang, energy-saving New Deal is expected to stimulate sales of home appliances of RMB 100 billion this year. However, due to the pre-stimulus policies, there are certain overdrafts in the household appliances industry in rural areas and in urban renewal demand. The incremental pull effect is decreasing compared with previous policies. The probability of all types of household appliances industry returning to 30% to 40% high growth in 2010 is very small.
Taking into account the favorable policies such as energy-saving subsidies, the final bus effect of home appliances to the countryside at the end of the year, the recovery of residential sales, and the lower base number in the second half of the year, many analysts believe that the demand for the home appliance industry will pick up in the second half of the year.
Wang Nianchun believes that the complete machine manufacturers will cooperate with the energy-saving subsidy policy and focus on the introduction of new home appliances, together with the targeted sales promotion activities of home appliance retailers, household appliances consumption will be further expanded. CICC expects that sales of refrigerators, washing machines, air conditioners, and color TVs will increase by 2%, 7%, 5%, and 8%, respectively, from May to December 2012. In the first five months of the year, sales of air conditioners, refrigerators, and color TVs fell 6.2%, 6.6%, and 1.1% year-on-year, respectively. Only washing machine sales rose by 2.2% year-on-year.
HDI PCB Specification
High density interconnect (HDI) PCBs represent one of the fastest-growing segments of the printed circuit board market. Because of its higher circuitry density, the HDI PCB design is able to incorporate finer lines and spaces, smaller vias and capture pads, and higher connection pad densities. A high density PCB features blind and buried vias and often contains microvias that are .006 in diameter or even less.
HDI PCBs are characterized by high-density attributes including laser microvias, fine lines and high performance thin materials. This increased density enables more functions per unit area. Higher technology HDI PCBs have multiple layers of copper filled stacked microvias (Advanced HDI PCBs) which creates a structure that enables even more complex interconnections. These very complex structures provide the necessary routing solutions for today's large pin-count chips utilized in mobile devices and other high technology products.
The HDI PCBs we offer include the following highly requested characteristics:
Blind and/or buried vias
Via-in-pad
Through vias from surface to surface
20 µm circuit geometries
30 µm dielectric layers
50 µm laser vias
125 µm bump pitch processing
Applications
HDI PCB is used to reduce size and weight, as well as to enhance electrical performance of the device. HDI PCB is the best alternative to high layer-count and expensive standard laminate or sequentially laminated boards. HDI incorporate blind and buried vias that help to save PCB real estate by allowing features and lines to be designed above or below them without making a connection. Many of today's fine pitch BGA and flip-chip component footprints do not allow for running traces between the BGA pads. Blind and buried vias will only connect layers requiring connections in that area.
