What does PCBA mean?

The abbreviation of PCBA (Printed Circuit Board+Assembly), that is to say, the whole process of PCB blank loading by SMT and then by DIP plug-in, referred to as PCBA. This is a common way of writing in China, while the standard way of writing in Europe and America is PCB'A with "",which is called an official idiom.

Extended data:

App application

3C products such as computers and related products, communication products and consumer electronics products are the main application fields of PCB. According to the data released by the Consumer Electronics Association (CEA), the global sales of consumer electronics products will reach 964 billion US dollars in 20 1 1 year, with a year-on-year increase of 10%. The data of 20 1 1 is quite close to 1 trillion dollars. According to China Eastern Airlines, the biggest demand comes from smartphones and laptops, and other products with remarkable sales include digital cameras, LCD TVs and other products.

computer

Gartner analysts pointed out that notebook computers have been the growth engine of the personal computer market in the past five years, with an average annual growth rate of nearly 40%. Based on the expectation of weak demand for notebook computers, Gartner predicts that global PC shipments will reach 387.8 million units in 201/kloc-0 and 440.6 million units in 20 12, an increase of13.6 compared with 201/year. China Eastern Airlines said that in 20 1 1 year, the sales of portable computers, including tablet computers, will reach 220 billion US dollars, and the sales of desktop computers will reach 96 billion US dollars, making the total sales of personal computers reach 301600 million US dollars.

IPad 2 was officially released on March 3, 20 1 1, and the PCB manufacturing process will adopt 4th-order Any Layer HDI. The Any Layer HDI adopted by Apple's iPhone 4 and iPad 2 will trigger an industry boom. It is expected that any layer of HDI will be applied in more and more high-end mobile phones and tablets in the future.

smartphone

According to the latest market research report released by Markets and Markets, the global mobile phone market will increase to $34 1.4 billion in 2065,438+05, of which the sales revenue of smart phones will reach $258.9 billion, accounting for 76% of the total revenue of the whole mobile phone market. Apple will lead the global mobile phone market with 26% market share.

IPhone 4 PCB adopts any layer of HDI board and any high-density connection board. In order to fit all the chips on the front and back of iPhone 4 on a very small PCB area, using any layer of HDI board can avoid the space waste caused by drilling holes in the machine ring and achieve the purpose of conducting any layer.

Tactile control panel

With the popularity of iPhone and iPad in the world, as well as the popularity of multi-touch applications, predicting the touch trend will become the next wave of growth driving engine for soft boards. DisplaySearch predicts that the shipment of touch screens for tablet computers will reach 260 million pieces in 20 16, an increase of 333% over 201year.

E-books/e-books/e-books

According to the forecast of DIGITIMES Research, the global e-book shipment is expected to reach 28 million units in 20 13, with a compound annual growth rate of 38.6% from 2008 to 20 13. The analysis points out that by 20 13, the global e-book market will reach 3 billion dollars. The design trend of PCB board for e-books: first, it is required to increase the number of layers; Second, blind hole burying technology is needed; Thirdly, a PCB substrate suitable for high frequency signals is needed.

digital camera

ISuppli said that as the market becomes saturated, the production of digital cameras will stop in 20 14. It is estimated that in 20 14, the shipment volume will drop by 0.6% to 654.38+354 million units, and low-end digital cameras will encounter strong competition from camera phones. However, some areas of this industry can still achieve growth, such as hybrid high-definition (HD) cameras, future 3D cameras and digital SLR (DSLR), which are relatively high-end cameras. Other growth areas of digital cameras include the integration of GPS and Wi-Fi functions to improve their attractiveness and daily use potential. To further promote the flexible board market, in fact, any light and short electronic products have a strong demand for flexible boards.

liquid crystal TV

DisplaySearch, a market research company, predicts that in 2065,438+0, the global LCD TV shipments will reach 2,654,380+05 million units, up 65,438+03% year-on-year. 20 1 1 year, due to the gradual replacement of LCD TV backlight by manufacturers, LED backlight modules will gradually become the mainstream, which will bring technical trends to LED heat dissipation substrates: heat dissipation substrates with high heat dissipation and accurate size; Strict line alignment accuracy and high quality metal line adhesion; Thirdly, the thin film ceramic heat dissipation substrate is made by yellow lithography technology to improve the high power of LED.

led lighting

Analysts of DIGITIMES Research pointed out that in response to the ban on the production and sale of incandescent lamps in 20 12 years, the shipment of LED bulbs in 20 1 1 year will greatly increase, with an estimated output value of about 8 billion US dollars. In addition, countries such as North America, Japan and South Korea will implement subsidy policies for green products such as LED lighting. As well as the high willingness of stores, shops and workshops to replace LED lighting, the global LED lighting market penetration rate has a great chance to exceed 10% in output value. 20 1 1 soaring LED lighting will definitely drive a large demand for aluminum substrates.
