  • How to do aging test in PCBA processing in Chinese factories?

    In order to ensure the stability and reliability of PCBA products, after the completion of PCBA production, it is best to carry out an aging test. The main purpose of the aging test is to simulate the daily use environment of the product to expose the defects of the PCBA, such as the defects of the products, such as the high temperature, low temperature, high and low temperature changes and electrical power. Bad welding, mismatch of component parameters, and fault caused in the process of debugging, in order to eliminate and improve, it will play the role of stable parameters to the PCBA board without defect....

  • What is the "burning" program in PCBA?

    In the process of PCBA processing, in order to enable the PCB board to achieve certain specific functions, in addition to the hardware problem, but also need to join the software function. At this time, we need to carry out the "burning" program. Before starting the "burning", we should test whether the PCB board is qualified, and then choose the appropriate burning mode. Nowadays, the way of burning is usually divided into offline burning and online burning....

  • What is a PCBA test?

    The process of PCB Assembly is very complex, including PCB board manufacturing, component procurement and inspection, SMT assembly, DIP plug-in, PCBA test and many other important processes. Because in the process of production, various problems may occur due to improper equipment or operation, so it cannot make sure that the produced products are all qualified. Therefore, PCBA testing is needed to ensure that no quality problems occur with each product. The PCBA test mainly includes five forms: ICT test, FCT test, aging test, fatigue test, and harsh environment test....

  • What is the PCBA stress test principle?

    First, the strain gauges are attached to several different positions on the PCB. When the process or work station is operated, the strain gauges are connected to the measurement instrument system to make the stress quantitatively display the records. Namely: Strain - Resistance Change - Voltage (or Current) Change - Magnification - Recording - Data Processing...
