Flex Circuits Fit Where Cables Cannot

Flex printed circuits can provide several obvious advantages over conventional ribbon cables in certain applications. For example, a flex circuit can span between a board and a connector on a bulkhead several inches away at a right angle in the same plane as the board. That’s not feasible with a ribbon cable. A flex circuit can be formed in complex shapes in three dimensions with branches to multiple connectors, which would be impossible to achieve with a ribbon cable. Moreover, flex circuits can be interfaced with rigid boards without the relatively tall and bulky connectors flat cables require, or in [...]

Automated Optical Detector(AOI) For Printed Circuit Board

Printed circuit board (PCB) are substrates for assembling electronic components. The manufacturing quality of PCB directly affects the reliability of electronic products. Therefore, PCB are known as the "mother of the modern electronics industry." With the in-depth development of electronic assembly toward higher-density, smaller-sized PCB hybrid technology, relying only on traditional functional testing and manual visual inspection and inspection methods, it has been unable to meet the needs of modern PCB industry's large-scale production. At present, the primary yield of general PCB is still hovering between 60% and 70%. In order to reduce the number of defective circuit boards that [...]

5 Questions to Ask PCB Manufacturer

With so many PCB manufacturers to choose from, it's easy to feel overwhelmed with picking the right one. This may come as a surprise, but not all PCB manufacturers are created equal.  In fact, by asking these questions before you choose a PCB manufacturer, you'll get to see firsthand how some manufacturers simply don't measure up to others. 1.How many years have you been in business? When it comes to manufacturing circuit boards, experience is everything. This question not only sheds light on a manufacturer's competence, but also their ability to constantly adapt and innovate over time. 2.What are your certifications? Often times, PCB [...]

The difference between Core and Prepreg

The Prepreg is an insulating material for the PCB. Prepreg is not prepreg before being laminated, also known as prepreg,prior to lamination, and is primarily used as a bonding material and an insulating material for the inner conductive pattern of a multilayer printed circuit board. After the Prepreg is laminated, the semi-cured epoxy is extruded, begins to flow and solidifies, bonds the multilayer sheets together and forms a reliable insulator.   The Core is the basic material for making printed circuit boards. The Core is also known as the core board, which has a certain hardness and thickness, as well [...]

Printed Circuit Board industry accelerates transfer to China

The industry moves eastward and the mainland is unique. The focus of the PCB industry is constantly shifting to the Asian region, and Asia's production capacity is further transferred to the mainland, forming a new industrial structure. With the continuous transfer of production capacity, mainland China has become the region with the highest PCB production capacity in the world.   Applications such as data centers will increase HDI demand, and FPC will have broad prospects. Data centers are moving in the direction of high speed, high capacity, cloud computing and high performance, and construction demand is exploding. The demand for [...]

Automated Optical Inspection (AOI)

Automated Optical Inspection (AOI) is the automated visual inspection of a Printed Circuit Board (PCB) in which a camera is used to scan the board in extremely fine detail to check for any defects or failures. So why is AOI so important? Assuming your PCB design is correct, if you assemble the right parts in the right place then your product will work. In production, this means putting a lot of focus on detecting and correcting any manufacturing defects or Manufacturing Defects Analysis (MDA.) AOI is a vital inspection system which enables you to measure and monitor the quality of [...]

The role and difference of solder mask and solder paste layer

The impact of many projects on solder masks and solder layers is unclear. It is to open the window itself, but only provides the paste layer. There is no solder layer. Some board engineers don't look at the paste layer (note that this is used). This is a useless layer for the plant's engineers and can cause window leaks. The following is a brief introduction to their differences.      The solder layer is used to control the area where the green oil (white oil) is not covered when the board is fabricated. For example, the position of the pad, [...]

Who Can Benefit From Turnkey PCB Assembly Services?

Advantages of Full Turnkey PCB Assembly Services and Who Can Benefit From Turnkey PCB Assembly Services? • Shorter Lead Time As a fundamental form of electronic assembly, PCB assembly primarily contains three phases: PCB fabrication, components procurement and PCB assembly. Traditionally, you should quote and confirm design files with sales and engineers working for your PCB manufacturer, then components distributors and finally PCB assemblers. Such series of quotations and confirmations just need your time spent in contacting with different partners. If those partners are from different countries, you have to overcome some problems such as time zone, communication habits etc. Full-turnkey [...]

How to Identify Circuit Board Electronics Components?

How to Identify Circuit Board Electronics Components? Start by identifying the printed circuit board, or PCB. This is the underlying rectangular chip or board, often in green or blue. This chip is covered in conductive pathways--little lines of metal that are actually printed on the board by another machine during production. Notice that each of these lines starts with a dot and is most likely labeled with a number. Though they are not wires, each of these connective lines works in the same manner as a wire to transmit independent lines of electricity. Identify other "nuts and bolts" electronic circuit [...]
