PCBA Tech - What does PCBA mean?

PCBA=Printed Circuit Board Assembly, which means that the empty PCB board goes through the SMT assembly and then goes through the entire manufacturing process of the DIP plug-in, referred to as the PCBA manufacturing process.

SMT and DIP are both ways to integrate parts on the PCB. The main difference is that SMT does not need to drill holes on the PCB. In DIP, the PIN pins of the parts need to be inserted into the holes that have been drilled.

It is important to develop a robust test strategy for large-scale, high-density printed circuit board assembly (PCBA, printed circuit board assembly) to ensure compliance and functionality with the design.

In addition to the establishment and testing of these complex assemblies, the money invested in electronic components alone can be very high-when a unit is finally tested, it can reach $25,000.

PCBA is the abbreviation of Printed Circuit Board + Assembly in English, which means that the empty PCB board goes through SMT loading, and then goes through the entire process of DIP plug-in, referred to as PCBA. This is a common way of writing in China, and the standard way of writing in Europe and America is PCB. 'A, with "'" added, this is called the official idiom.

application

3C products such as computers and related products, communication products and consumer electronics are the main application areas of PCB. According to data published by the Consumer Electronics Association (CEA), global consumer electronics sales will reach US$964 billion in 2011, a year-on-year increase of 10%. The data for 2011 is quite close to USD 1 trillion. CEA said that the biggest demand comes from smart phones and laptops. In addition, products with significant 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 expectations of weaker notebook computer demand, Gartner predicts that global PC shipments will reach 387.8 million units in 2011 and 440.6 million units in 2012, an increase of 13.6% over 2011. CEA stated that in 2011, sales of mobile computers, including tablets, will reach US$220 billion, and sales of desktop computers will reach US$96 billion, bringing total sales of personal computers to US$316 billion.

The iPad 2 was officially released on March 3, 2011, and the fourth-order Any Layer HDI will be used in the PCB manufacturing process. The Any Layer HDI adopted by Apple iPhone 4 and iPad 2 will trigger an upsurge in the industry. It is expected that Any Layer HDI will be used in more and more high-end mobile phones and tablets in the future.

smart phone

According to the latest market research report released by Markets and Markets, the global mobile phone market will increase to 341.4 billion U.S. dollars in 2015, of which smartphone sales revenue will reach 258.9 billion U.S. dollars, accounting for 76% of the total mobile phone market revenue; and Apple will Leading the global mobile phone market with a market share of 26%.

iPhone 4 PCB uses Any Layer HDI board, any layer of high-density connection board. In order to fit all the chips on the front and back sides of the iPhone 4 in a very small PCB area, the Any Layer HDI board can avoid the waste of space caused by booting or drilling, and achieve the purpose of enabling any layer to be conductive.

Touch panel

With the popularity of iPhone and iPad around the world, multi-touch applications are popular, and it is predicted that the touch wave will become the next wave of growth driving engines for soft boards. DisplaySearch predicts that tablet PCs will require 260 million touch screen shipments in 2016, an increase of 333% over 2011.

E-book

According to the forecast of DIGITIMES Research, global e-book shipments are expected to reach 28 million units in 2013, and the compound annual growth rate from 2008 to 2013 will be 386%. The analysis pointed out that by 2013, the global e-book market will reach 3 billion U.S. dollars. The design trend of PCB boards for e-books: First, the number of layers is required to increase; second, the blind and buried via process is required; third, the PCB substrate suitable for high-frequency signals is required.

Digital camera

iSuppli said that as the market becomes saturated, digital camera production will begin to stagnate in 2014. It is estimated that shipments in 2014 will drop by 0.6% to 135.4 million units, and low-end digital cameras will encounter strong competition from camera phones. However, certain areas of the industry can still achieve growth, such as hybrid high-definition (HD) cameras, future 3D cameras, and digital single-lens reflex (DSLR) such more high-end cameras. Other growth areas for digital cameras include the integration of GPS and Wi-Fi functions to increase their attractiveness and potential for daily use. Promoting the further improvement of the FPC market, in fact, any light, thin, short and small electronic products have a strong demand for FPC.

LCD TV

Market research company DisplaySearch predicts that global LCD TV shipments will reach 215 million units in 2011, a year-on-year increase of 13%. In 2011, as manufacturers gradually replace the backlight of LCD TVs, LED backlight modules will gradually become the mainstream. The technological trends brought to the LED heat dissipation substrate: a high heat dissipation, precision size heat dissipation substrate; two strict line alignment Accuracy, high-quality metal circuit adhesion; Third, use yellow light lithography to make thin-film ceramic heat dissipation substrates to improve the high power of LEDs.

LED lighting

Analysts from DIGITIMES Research pointed out that in response to the ban on the production and sales of incandescent lamps in 2012, LED bulb shipments will grow significantly in 2011, and the output value is estimated to be as high as approximately US$8 billion. Driven by factors such as the implementation of subsidy policies for green products such as LED lighting, and the high willingness of stores, shops and workshops to replace them with LED lighting, the global LED lighting market penetration rate in terms of output value has a high chance to exceed 10%. LED lighting, which took off in 2011, will surely drive a large demand for aluminum substrates.

PCBA refers to the entire manufacturing process of PCB blank board after SMT loading and then DIP plug-in. It is the abbreviation of Printed Circuit Board + Assembly in English.

This is a commonly used wording in China, while the standard wording in Europe and the United States is PCB'A, with "'" added, which is called the official idiom.

Expansion information:

Printed circuit board, also known as printed circuit board, printed circuit board, often uses the English abbreviation PCB (Printed circuit board), is an important electronic component, a support for electronic components, and a provider of circuit connections for electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board. Before the advent of printed circuit boards, the interconnection between electronic components relied on the direct connection of wires to form a complete circuit.

Until 1936, the Austrian Paul Eisler (Paul Eisler) published the foil film technology in the United Kingdom, he used a printed circuit board in a radio device; and in Japan, Miyamoto Yoshinosuke sprayed the wiring method "メタリコンWiring method (Patent No. 119384) "Successfully applied for a patent."

Of the two, Paul Eisler’s method is the most similar to today’s printed circuit boards. This type of method is called subtraction, which removes unnecessary metal; while Charles Ducas and Miyamoto Kinosuke’s method is to add only what is needed Wiring is called the additive method.

The changes in PCB application structure and product structure reflect the future development trend of the industry. In recent years, with the decline in the output value of single/dual-panel and multilayer boards, the increase in the output value of HDI boards, package carrier boards, and soft boards indicates that the growth in applications such as computer motherboards, communication backplanes, and automotive boards has been relatively slow.HDI boards, packaging boards and soft boards for high-end mobile phones, notebook computers and other "light, thin, short and small" electronic products will continue to grow rapidly.

PCB refers to the printed circuit board, and PCBA refers to the process of soldering or mounting electronic components on the printed circuit board.
