How Automated Optical Inspection Improves PCB Assembly Quality

Automated Optical Inspection, also known as AOI, really helps increase the quality of PCBs during assembly. We know at Engine that every custom pcb assembly needs to be right! This means using our high-tech AOI system. We can quickly and efficiently check every single PCB coming off the assembly line to look for things like incorrectly positioned components and solder defects. AOI uses both high-resolution cameras and smart software to take very detailed close-ups of the PCB; the defects can be detected at a very early stage which saves a lot of time. 

How AOI Benefits the Wholesale Buyers? 

The key value for wholesale buyers of PCBs are the quality of the product, the ability to use it for a long period of time, and also the guarantee that every single product will function exactly as intended. With the implementation of AOI within the Engine assembly system the buyer will have a stronger sense of confidence that each and every one of their boards are high quality and will not return a high percentage of defects back to them. The quality checks can scan through a number of different qualities such as missing or improperly placed components and even minute details such as scratches and blemishes upon the board itself; this quality control system significantly reduces the possibility of product return and provides peace of mind to the wholesale buyer who in turn has happier customers that will be more likely to return to them for another order. It is a way for the buyer to take their business and know with a sense of certainty that the quality control system used for their PCBs is one of the very best on the market. It also significantly lowers the price for these wholesale buyers by reducing wasted costs as every defect is quickly caught, fixed and therefore removed before becoming a larger, more costly problem. We at Engine know this is a great benefit for all parties involved in the process; especially to the consumer of the final product who benefits from a fully functional and quality item. 

How AOI Reduces the Defect rate of PCBs to a Suppliers? 

Every wholesale supplier needs to focus on the quality and reduction of defects within their PCBs. Defects can lead to decreased customer satisfaction, a lower reputation within the marketplace and most importantly, wasted profit. Through the use of the automated optical inspection technology system that is employed within the Engine manufacturing process suppliers can efficiently ensure that their boards are properly assembled from start to finish, in one simple step. It works through the inspection of boards as they are constantly moving down the assembly line and any errors are detected on the spot, fixed in that same stage of assembly or, if possible corrected on the fly by the assembly worker, meaning that all aspects of each PCB have been fully analyzed and checked for any anomalies. An AOI inspection machine can scan and inspect up to a certain percentage of every component upon the PCB, this is the ultimate way to detect and fix a flaw such as an improperly placed part that has yet to reach the finished product. These types of flaws when caught so early on are inexpensive to fix. A defect that is not caught early will have a much greater cost both in time and financially; it is also likely to result in a poor customer review and the customer wanting their product and their money back. 

How AOI Is Benefiting PCB Assemblies? 

AOI is a great way of checking the quality of PCB assemblies. Just as if a child had tried to fit two puzzle pieces together and they hadn't met properly and there was another little detail to ensure that two puzzle pieces connect, AOI checks for every detail on a PCB. Through using high resolution cameras along with smart and intelligent software the AOI technology is capable of detecting any problems that are present on the board. If there is a problem such as missing components, AOI can be programmed to detect this and ensure that the mistake does not pass through the assembly line, the product is checked quickly and accurately; thereby ensuring that problems are caught long before the board gets anywhere near the consumer. Take a slight solder defect on the other hand; this would take a person several minutes to observe from up close where as our AOI machines can detect these faults within a second of scan. The earlier in the pipeline that the quality check is performed on a product the cheaper it is to fix and the quicker that the corrected item can be delivered to the customer; all leading to a better final product and more sales for the wholesale supplier or seller. The AOI systems that we employ here at Engine will ensure that all of our customer's orders are fulfilled with high quality PCBs and they know they will be purchasing quality product from us at all times thereby building strong brand loyalty. In essence the pcb main assembly is a sophisticated method to ensure that high quality, working products reach our customer every single time that they buy from us. 

Choosing The Right AOI Machine for Your PCB needs

There are several factors that you need to consider before making the choice to invest in a PCB AOI machine that is perfectly tailored to your assembly needs. First and foremost, you need to consider the specific type of PCB that you are manufacturing: this could refer to a board that is small, one that is quite large, a board with many surface mounted devices or even a board that only has components on one side. Each of these will require a specific system that can analyze the board thoroughly. Next to this you must consider the speed and throughput that your manufacturing line requires; do you produce a large number of boards at a high pace, or do you produce fewer boards at a more steady rate? This is where a specialized and high performance AOI system comes into play. It will also be very important to ensure that the machine's software package is user-friendly, allows for easy result inspection and programming, and provides thorough yet simple to analyze statistical data on the boards' inspection processes; of course, good support from the vendor will be critical should something go wrong with the machine itself. Finally the budget has to be taken into consideration; although investing a great deal of money may seem appealing, it must first be reconciled against the expected results and be affordable for the consumer. With consideration for these specific aspects it should be easy for any supplier to obtain an AOI system that truly matches all of their needs. 

How AOI Systems Gives you an Advantage in PCB Production? 

PCB production is a rapidly developing and highly competitive industry that requires you to constantly find new ways to stand out amongst the rest of your competitors. Using the highly advanced automated optical pcb smt assembly here at Engine will be very advantageous for you. High quality products lead to trust, which leads to customer retention, loyalty and significantly increased sales due to the fact that buyers know that they are purchasing quality goods from a reliable source; this will make you stand out greatly in the eyes of a customer or a buyer of the PCBs. It saves the supplier or manufacturer significant amounts of time, money and wasted resources due to the fact that errors are detected so early on in the production process and can be fixed instantly; thus reducing the rate of defect by as much as 99.9%. The higher rate of inspection ensures that you can produce more items at an quicker pace and also ensure that all orders are fulfilled to the exact specifications that are requested by the buyer every single time. You can also put focus elsewhere while the AOI system constantly keeps the board quality under review, thus making for a more streamlined manufacturing process. In essence, an automated optical inspection machine gives you a much larger production capacity at a greatly reduced cost of production.
