The highest demand used in quality management of electronic printed circuit boards (PCBs) and PCB assembly [1] is automatic optical inspections and automated optical inspections (in short, AOI) (PCBA). AOI inspects the electronic assemblies such as PCBs mechanical visual inspection to ensure that the components of PCBs are in the right place and the contacts are correct. Automated optical inspection (AOI) is an intelligent visual inspection of the production of the printed circuit board, where all catastrophic failures (such as broken components) and quality faults can be scanned automatically by a sensor. It is widely used in the production phase because it ...
In this article, you'll get to know the fundamentals of PCB manufacturers and how our company "PNC [1] Inc." is unique from other manufacturers in the United States. What are the three main aspects of the PCB industry? According to our experience of more than 50 years as the leading PCB Company in the industry, we can easily write that three main aspects in the PCB industry for which most clients look for are: • PCB Design [2] • PCB Manufacturing [3] • PCB Assembly [4] Design, Manufacturing, and assembling of PCB is a systematic method for examining the parts and components which is needed to ...
When it comes to reducing the manufacturing cost of a PCB, it is important to remember that a significant part of the cost of a PCB assembly [1] is already baked in at the design concept stage. The product concept defines the PCB size and shape, while the performance of the system dictates the microprocessor, memory and other functional elements of the circuit. However, some of the assembly cost can still be affected by design choices made by the PCB designer. A PCB that is designed for manufacturing (DFM) can reduce both the fabrication cost of the PCB and the costs ...
No company can excel at every aspect of new product development and trying to do everything can dilute an organization’s focus on the tasks that are essential to its success. For example, most companies have long ago outsourced the PCB design and fabrication steps of new product development. This same need to focus on the essential is true of software development too. It is difficult for a software company to excel at every type of software development because of the ever expanding universe of software languages, operating systems, and architectures. A cloud based SAAS or PC based application is very ...
In this ongoing series on PCB layout from the design team at PNC, previous posts have looked at some of the initial steps to turn a circuit schematic into a manufacturable, reliable PCB. These posts have looked at component placement [1], selecting appropriate trace widths [2], and BGA routing [3]. In this post we are going to take a deeper dive into methods for reducing crosstalk in the PCB design [4]. After the power and ground have been routed, the next task is to route high speed signal traces, and the traces that could either generate or receive crosstalk. What is ...
