As we all know, SMT electronic components are getting smaller and smaller, the density is getting higher and higher, and the quality requirements are also increasing.

The speed and quality of manual inspection cannot meet the requirements, and various AOI equipments are produced. AOI equipment has the characteristics of precision, speed, stability and reliability. So what is the working principle of AOI equipment?

How 3D AOI devices work?

1. How AOI equipment detects PCB boards

The SMT-AOI device uses hardware devices such as cameras to obtain the image of the detected object, and then uses software to compare, analyze, and determine whether the detected object is OK. That is to say, the process of AOI detection of objects is to simulate the detection of objects by human eyes, and to automate and intelligentize the detection of objects manually.

Image acquisition is to use a CCD camera to convert the light signal on the surface of the object into an electrical signal and send it to the image acquisition card. The frame grabber digitizes the image into the computer, and the process is intuitive and easy to understand.

2. How AOI equipment detects the quality of components

How does AOI check the quality of components? When people judge whether the quality of an object is qualified or not, it is always necessary to set a standard. If the standard is met, the object is considered qualified.

If the standard is not met, the object is considered unqualified. Similarly, AOI judges whether a component is OK or not, and also sets a rule. If the rule is satisfied, it is OK, and if the rule is not satisfied, it is NG.

AOI uses different rules for different components. The most commonly used rule is the standard image, which is to assign a standard image to a patch in advance. If the image of the detected patch is very similar to the standard image, then we consider this patch. It is OK. If it is not similar, it is considered NG

In the image processing industry, we call this rule image comparison or template matching. In addition, there are some specific rules, such as specifying that ICs cannot be bridged.

This is not by specifying a standard image, but a method of calculating whether there is a connection between the two ICs by some algorithm to determine whether the IC has a bridge phenomenon.

Here at CNSMT, we have everything that you need!


Question: What does a 3D AOI machine really do? Is it important to have if I already have an inspection machine?

Answer: A 3D AOI machine makes thorough and proper inspection on printed circuit boards. It carefully inspects the X, Y and Height. This will give you the peace of mind that a full inspection is done on your circuit boards.

3D AOI machines are considered the newest and most powerful inspection machines of today.

Question: If I am going to order a 3D AOI machine today, when will I get it? I am outside China. Do you ship worldwide?

Answer: Yes, we ship worldwide via sea and air. For us to give you a proper estimate for the lead time of your order, we would like to ask for your exact shipping address first and the type of shipment you prefer.

Shipping via sea will take longer days compared to shipping via air. Thus, the cost may also differ.

Please contact us via email so we can give you a proper quotation for this.

Question: Do you have the 3D AOI machine ready for shipping already?

Answer: Since the AOI machines are very much in demand nowadays, we keep several units in stock in our warehouse. However, we work on a first come first serve basis. If you are sure of ordering the unit from us, kindly communicate via email so we can process your invoice.

Only paid clients will be served. Once your order is paid, we will proceed to doing the final quality check on your machine before we pack them and hand it to our shipping partner.

This process will require days. We will give you an update once the machine is ready for shipping. We will also provide you with a tracking number once your order leaves our warehouse.

Question: This is our first time purchasing a 3D AOI machine. Is there someone who can help us to understand the machine first before we make the final purchase?

Answer: If you require a demo of the machine, let us know. We have a team of professional engineers who can show you a demo of the machine. You may also ask the team your questions to help you make an educated buying decision

If you are able to visit our warehouse, the team is ready to conduct the demo personally. You need to schedule your visit with us, so that we can properly arrange it for you.

If you are based overseas, you can request for an online demo.

SMT FULL LINE MACHINEQuestion: Is there a minimum order requirement for the 3D AOI machine?

Answer: There is none. You can place an order for one machine only and we will be more than glad to process the order for you.

Question: If the machine malfunctions after the warranty period, and our engineers need parts replacement, can we order it from your company again?

Answer: Yes. If you need parts replacement, all you need to do is contact us back and we will work hard in finding the part/s that you need. We will also give you a discounted rate for being a loyal customer.

Question: Is the 3D AOI better than the common AOI machines we already have in our assembly?

Answer: AOI machines work by scanning a printed circuit board and capturing the image of it. The image will then be matched with the right image set in the machine, to ensure 100% quality copy is made every single time.

A standard AOI machine can scan boards as simple as that. But a 3D AOI makes a scan in three different dimensions, such as the X, Y and height.

Doing so will simply produce better and higher quality results in your assembly.

Question: Some people say combining 3D AOI and 2D AOI is the best. Is that true?

Answer: In general, the answer is yes. While 3D AOI does the best scanning and inspection on boards, the additional layer of inspection will obviously add more to the time needed to complete a cycle of inspection.

Therefore, if you combine 2D and 3D and use the machines according to what boards are being inspected, then you can manage the time better and produce results within the fastest time possible.

Question: I want to place an order for the 3D AOI machine. Do you price match?

Answer: We understand that you may have talked to several suppliers of the 3D AOI machine already and you have received several quotations too. Here at CNSMT, we are very much open to negotiations. Let us know more about the quotation that you received and we will try to price match it and to give more value to your money.

Question: Are the machines covered with warranty especially to those that will be shipped overseas?

Answer: Yes. All orders from our company are covered by warranty. We also offer coverage to keep your machine safe during shipping. Just to let you know, we ship machines overseas on a daily basis, and we are happy to say that we seldom get concerns about it.

But for your peace of mind, all orders are covered with warranty and you should be able to see that from the email that we are going to send you prior to making your payment, so that you can review all details first.

Question: Do you give discounts on multiple orders?

Answer: If you have plans on ordering more than 2 units of the 3D AOI machine or if you plan on ordering other machines / equipment / accessories together with your 3D AOI machine, let us know.

We will give you a quote and give you the best price for each of the machines you wanted to order from us. So far, our company provides the best and most competitive price in the market today.
