Phil, as a rule of thumb, measuring machines (such as Zeiss, View and others) should be ten times more accurate, than the placement machine, in order to provide measuring values (CPK). AOI are meant to detect missing and wrong components, but not mea

Marcus- I guess I'm too old school. When I was involved in manufacturing there wasn't any AOI and we got along fine for years without it, (like everyone else). But I can certainly see the benefits of it if you have highly complex boards that are jus

Hi, I have 4 years as an AOI Process Engineer and we are working with 3 types of AOI - Marantz 22X, VI3000 and Omron (RNS & VT-WIN2). For solder joint inspection (solder meniscus quality, insufficient solder, wetting problems, shorts (bridges) Omron

I am going through the process of re-evaluating our AOI systems. Depending on the complexity of your assemblies, I would recommend Mirtec's, and aoi systems as the previous post suggests. Had a demo from them a month or so ago and for the price the

I already understood thank you very much. In fact, between the oven and the AOI we have a conveyor that measures around 6.5 ft. Only in this case we set the time of the line so that the process was efficient, now that the AOI increased its loading an

Andy, AOI is a worth-while tool for verifying part placement on those pesky little telecommunication boards that are too small for referance designators. It can also be a valuable verification step to reinforce quality control. Pros and Cons o

We attended several presentations on AOI machines at a recent SMTA meeting. The presenters gave a section about process verification. They bantied about numbers. [I want to say 350 DPMO, but we glaze over when it gets to that stuff] So, you might

Hi Jorge, The success of such production purely depends on process control. One needs to first understand the board layout in detail, and evaluate any critical components for their temperature handling capabilities. Remember, you are dealing with com

Achieving high reliability and high efficiency in SMT process (Surface Mount Technology) assembly has always been the goal of electronics manufacturers expecting consistency. It depends on the optimization of every detail of the whole process. For SM

Advantages of SPI 1. Reduce defects SPI was first used to reduce defects caused by improperly printed solder paste. Therefore, the primary advantage of SPI is its ability to reduce defects. Defects have always been a major problem when it comes to
