FR4 Aluminum Hight TG 4oz PCB Circuit Board 1.6mm Thickness

PCB circuit board (PCB),

also known as printed circuit boards, printed circuit board, or PCB, English abbreviation PCB (printed circuit board) or the PWB (printed wiring board), insulation board as base material, cut into a certain size, with at least one conductive graphics, and cloth have a hole (such as component hole, fastening hole, hole metallization, etc.), electronic components at the bottom of the plate used instead of previous unit, and realize the connection between the electronic components.Because this kind of plate is made by electronic printing, it is called "printed circuit board".The customary term "printed circuit board" is not accurate, because there are no "printed components" on the printed board, only the wiring.

Introduction of printed circuit board assembly (PCBA) process flow

Electrons are an indispensable part of our daily life.Everything from smartphones to cars includes electronics.At the heart of these electronic products are printed circuit boards, also known as PCBs.
Most people recognize a printed circuit board when they see it.These are small green chips covered with lines and copper parts that you can find in the heart of visceral electronics.The plates are made of fiberglass, copper wire and other metal parts, held together with epoxy resin and insulated with a solder resistance film.This solder resistance film is characteristic of where the green comes from.
But have you ever observed those components stuck?

Never think of them as decoration on a PCB.An advanced circuit board will not be able to provide its functionality until the components are installed on it.PCBs with components are called assembly PCBs, and the manufacturing process is called PCB assembly or PCBA for short.Copper wires on the bare board (called trace wires) electrically connect the connectors and components to each other.They run signals between these functions, allowing the board to operate in a specially designed way.These features range from simple to complex, but PCB sizes can be smaller than thumbnails.

So how exactly are these devices made?

The PCB assembly process is simple and includes several automatic and manual steps.Through each step of the process, the board manufacturer has manual and automatic options for you to choose from.To help you better understand the PCBA process from start to finish, we explain each step in detail below.Basics of PCB design

The PCBA process always starts with the most basic unit of the PCB: the base consists of multiple layers, each of which plays an important role in the functionality of the final PCB.These alternate layers include:
Substrate: This is the base material for PCB.It gives the PCB rigidity.
Copper: Add a thin layer of conductive copper foil to each functional side of the PCB

PCBA using hybrid technology should be performed under the following conditions:
? Single-sided Mixed Components: Single-sided Mixed Components conform to the following manufacturing procedures: Note: When only a small number of THT components are required in such components, hand soldering may be used instead of wave soldering.
? Single-sided SMT and Single-sided THT: Note - this type of PCB assembly procedure is not recommended as adhesives can add to the total cost of PCBA and may cause some soldering problems.
? Two-sided mixed assembly: In terms of the two-sided mixed assembly method, there are two options: PCBA with adhesive and PCBA without use.The use of adhesives increases the total cost of PCB assembly.Moreover, in this PCBA process, heating must be done three times, which often leads to inefficiency.
Based on the comparison between the hybrid assembly procedures described above, it can be concluded that manual welding is suitable for PCB assembly, which requires many components on both sides, with more SMD components than THT components.Therefore, when a small number of THT elements are required, wave soldering is recommended.
PCB assembly must go through such a complex and technical process that many elements must be carefully considered, and minor modifications can lead to huge changes in cost and product quality.The description of the PCB assembly process in this article centers only on typical PCBA programs and techniques.The actual manufacturing process depends to a large extent on the design document and the specific requirements of the customer.Therefore, how to evaluate a reliable PCB assembler becomes a key issue that customers must consider before placing a PCBA order.

Domestic printing

The research of the automatic detection system of circuit board began in the early and middle of the 90's, and it just started.There are few scientific research institutes engaged in this research, and because of the influence of various factors, the research on the automatic optical detection system for printed circuit board defects also stays at a relatively early level.Because the foreign printed circuit board automatic detection system price is too expensive, and the domestic also did not develop a real sense of the printed circuit board automatic detection equipment, so the majority of domestic circuit board manufacturers or by manual magnifying glass or projector view of the way to check side.Due to the labor intensity of manual inspection, eye fatigue is easy to produce, and the rate of missing inspection is high.And with the development of electronic products toward miniaturization, digitalization, printed circuit board also toward the development of high density, high precision, the use of manual inspection method, basically unable to achieve.For higher density and precision circuit board (0.12~0.10mm), it has been completely unable to test.The backward detection means lead to the current domestic multi-layer board (8-12 layers) product qualified rate is only 50~60%.

advantage

Industrial policy support
According to the Outline of the Eleventh Five-Year Plan for China's national economic and social development, the electronic information manufacturing industry should be promoted, and core industries such as integrated circuits, software and new components should be vigorously developed according to the general trend of digitalization, networking and intelligentization.
According to the Ministry of Information Industry of our country "information industry science and technology development" the 11th five-year plan and the 2020 medium long-term plan outline ", printed circuit board (especially multi-layer, flexible, flexible and rigid combination and green environmental protection printed circuit board technology) is China's electronic information industry in the next 5-15 years one of the key development of 15 fields.In Dongguan, Shenzhen set up a lot of circuit board science and technology park.
The continuous and rapid growth of the downstream industry
The rapid development of China's information electronics industry provides a good market environment for the rapid development of printed circuit board industry.The continuous growth of the output of electronic products such as electronic communication equipment, electronic computers and household appliances has provided a strong driving force for the rapid growth of the printed circuit board industry.In addition, the issuance of 3G licenses will trigger massive telecom investment and demand for servers, storage and network equipment.According to the forecast of the Ministry of Information Industry of China, the growth rate of the scale of fixed assets investment in China's mainland telecom will reach 10.53% and 14.29% respectively in 2006 and 2007.

Labor cost advantage, manufacturing shift to China
Because of the preferential measures of Asian countries in terms of labor resources, market, investment and tax policies, the manufacturing industry from the United States and Europe is attracted to move to Asia, especially China.China is uniquely positioned to have a large number of electronics and equipment manufacturers set up factories on the Chinese mainland and thus drive the development of related industries.Printed circuit board as the basic electronic components, the market supporting demand growth is strong, the industry prospects are good.

disadvantage
Product homogeneity is high, the proportion of high-end plate is low, the ability of cost transfer is weak
Due to the fierce price competition, companies cannot transfer the cost increase factors to users, but can only rely on their own factors to digest. In the case of rising material cost, PCB price will not change greatly, but once the material cost drops, the fierce competition will make the price drop.
Product scale structure and key technology of local enterprises are insufficient
Small and medium-sized and private manufacturers are in the production capacity and technical level of low-grade products
There are no internationally accepted industrial standards
Lack of self and recognized brand
Insufficient attention to research and development, unable to engage in research and development
Advanced equipment and technology are mostly mastered in foreign-funded enterprises
Has not formed a complete set of complete, industry self-discipline market
Waste disposal does not meet environmental standards
