To use Automated Optical Testing, the PCB is usually tested after reflow soldering in SMT (Surface Mount Technology) assembly. In the process of PCB assembly, the PCB is tested to check if the PCB has any faults. It’s the widely used process for PCBA Testing due to several factors. We will try our best to explain each of these matters comprehensively. And even if you don’t know, you need not worry about it. You might have heard about the famous Automated Optical Testing if you have a mild idea about the PCB assembly process. The well-known ways of PCBA testing are as follow: However, we are going to mention the most famous ways for the testing of PCBA that are been used worldwide by international manufacturers. There are several ways for PCBA testing, and the manufacturers decide the one that is most beneficial for them. We will be discussing each type in great depth below. The PCBA testing is further divided into different types, depending upon your needs. The technicians have to deal with many complications and complex steps for PCBA testing. Engineers will analyze their test schemes, reserve PCB test points, and give professional test documentation or test plans to manufacturers when clients are designing PCB boards.Īs you must have guessed by now that PCBA testing isn’t simple as it sounds. To fulfill the goal of speedy PCBA testing, the PCBA test fixture connects the test needles and test points on the PCB board, obtains voltage, current, and other essential data, and then displays it on the test fixture's display screen. Large volumes of PCBA circuit boards must be examined, and a corresponding PCBA test fixture is frequently provided to help with this. So, we have mentioned the FCT fixture (Functional Circuit Test), but what is the PCBA Testing fixture? Let’s have a look at it below! To complete the PCBA item test, observe the voltage and current values between the test points on the FCT fixture and verify that these input and output actions are compatible with the design. The MCU application will catch the user's input action and apply calculations to turn on and off neighboring circuits or drive motor rotation. The FCT (Functional Circuit Test) fixture connects the test points on the PCBA circuit board to make a complete circuit that connects the computer and the programmer and uploads the MCU (Microcontroller Unit) software. Do you want to know what the PCBA testing principle is? To know about on what basis a PCB is tested, Read on! PCBA testing is based upon one concrete principle. Any PCBA maker should adhere to PCBA testing standards and conduct tests in accordance with the customer's test plan. PCBA testing is an important step in ensuring manufacturing and delivery quality. To check whether the real PCBA board fits the design requirements, professional test equipment or a manually operated multimeter must be used to detect the test points. There are numerical relationships between distinct test points in the PCBA item test, such as voltage and current. PCBA testing is the process of determining the electrical conductivity of a printed circuit board containing electronic components and detecting it using input and output values. Thus, keep reading this article till the end to get the best out of it.īefore we dive into the major details, let’s have a brief overview of the technical meaning of PCBA testing. It is because, in today’s article, we will explore PCBA testing in great depth. Therefore, if you want to know more about PCBA testing, you are at the right place. This step is essential as it ensures that the manufacturers don’t receive the faulted PCBA. And one of the major and last steps before the successful assembling of a PCB is the PCBA (Printed circuit board assembly) has to be tested. There are certain strict steps that a PCB has to go through before getting properly assembled. This process is called the assembling of PCBs. But before we implement the characteristics of a PCB, we have to undergo some steps to assemble the PCBs. We can’t think of any single electronic\tech device that doesn’t need a PCB. A printed circuit board (PCB) is one of the most important electronic devices that has been used in the modern world.
