AOI For Printed Circuit Board and PCB assemby China

Printed circuit board (PCB) and PCB assembly 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 [...]

How to Ensure the Quality of Printed Circuit Board and PCB assembly manufacturing

PCBs (Printed Circuit Boards) are the most used and basic PCB assembly unit applied by all types of electronic devices. All functions and performance of devices are implemented mainly by PCBs. Put simply, PCBs are the heart of electronic devices and both their quality and reliability is directly correlated with quality and reliability of electronic equipment. Nowadays, intelligence and miniature of electronic devices leads to increasingly smaller size and complicated structures of PCBs. In terms of PCB performance, it can be testified that even if schematic is correctly designed, subsequent assembly and debugging will still be influenced if PCB design [...]

The Importance of PCB Testing

Why Should I Test PCBs? The testing phase of PCB manufacturing is one of the most important stages. Without testing your PCBs, there may be errors and problems that have been overlooked during the production stage. These problems may eventually cause failures and defects in the field. In order to reduce the chance of failure and maintain customer satisfaction, it’s important that testing procedures are implemented to ensure that the printed circuit board and the components are fully functioning. Having testing procedures throughout the production phase allows you to identify errors and issues earlier on, rather than at the final [...]

Common Causes Of PCB Failure, Explained

Printed circuit boards can be found in virtually every tool we use on a daily basis. From computers and cell phones to our television sets and portable speakers, we rely on PCBs to make our world work. But sometimes, PCBs don't work the way they should. Whether due to material defects or environmental factors, here are just a few of the most common reasons for PCB failure. 1.Material Defects. A lot of things can potentially go wrong during printed circuit board assembly. Material defect is chief among the most popular causes for board failure. If a material used in the [...]

Colorful PCBs Does Solder Mask Hue Impact Functionality- Circuit Board Assembly

Traditionally, circuit boards are green. But today's world is more diverse -- even when it comes to PCBs! Although green boards are still popular, many PCB assembly services now offer a variety of solder mask colors to customers. What does this mean for the PCB fabrication and Circuit Board Assembly process? And can you expect to receive all different hues of PCBs when you place an order for circuit board assembly services? We'll discuss this colorful topic in today's post. In years past, PCB solder mask was almost exclusively green There are a few reasons for this. One is that [...]

Why You Need 3D X-Ray Testing- Printed Circuit Board Assembly-Hitech PCB

Printed circuit board assembly has come a long way in recent years. Now that PCB assembly can easily be performed by machine, PCB manufacturers have been able to increase their production and drastically reduce the time required for this process. In fact, a few PCB assemblers even offer standard turnaround times of three days or less -- 75% faster than the industry average. However, clients who rely on these circuit boards will never be willing to sacrifice quality for speed. In order to ensure PCB production maintains a high-quality standard and exceeds customer expectations, PCB assemblers must prioritize testing during [...]

Six methods to inspect PCB

PCBs are necessary to do electric inspection after manufacturing and assembling. We are professional PCB manufacturer which have been focous on PCB over 10 years. We offer PCB one stop services worldwide, so we attach great importance to electric inspection,we use all-round inspection with good inspect method to increase the efficiency on PCBs. The following are some measuring methods on PCBs,which will find out where short or open. If it is manual welding, we should form good habits. First of all, Visual check the PCBs before welding, and use a multimeter to check the key circuit (especially the power and [...]

Something About Automated Inspection Systems

Automated Optical Inspection (AOI) is as the name suggests a visual quantitative and qualitative test for PCBs. This automatic process allows companies to reduce their dependency on manual testing and thereby lessen any chances of human error. Since testing is an important process when it comes to the products provided by PCB assembly service providers, AOI systems offer immense reliability.   Need for Robust Testing Systems PCBs need to be produced according to certain guidelines put forth by leading organizations and Government bodies. Some specific reasons to opt for AOI testing include: AOI testing is an automated optical system. This [...]

Simple Ways to Repair Printed Circuit Board

Printed circuit board is a sophisticated component in any electronic device and the performance of the circuit board devices of the performance of the device itself. It can be easily said that if the printed circuit board of a device is either damaged or malfunctioning due to any reason then the device will not perform to the best of its responsibility.   In such cases, when it is highly recommended to have high standards while pcb manufacturing and designing the circuit board devices, the maintenance of the circuit boards is also an important aspect. A lot of times, the device [...]
